Description

This disclosure relates to technology for controlling dramatic effects.

At locations where various events such as competitive events or music events are held (hereinafter referred to as "event locations"), visual effects are important for creating a lively atmosphere. For example, Patent Document 1 discloses a technology for controlling the illumination of penlights held by spectators watching an event at the event location in response to control data transmitted from a control device. Furthermore, Patent Document 2 discloses a technology for illuminating the screens of mobile devices held by spectators at the event location with a flashing pattern transmitted by an audio beacon.

JP 2013-4323 A JP 2016-134162 A

Incidentally, not only can spectators who actually attend the event location watch the event, but viewers in locations other than the event location can also watch the event in real time by distributing video content of the event. However, viewers in locations other than the event location can only watch the video content and cannot participate in the production effects at the event location. In consideration of the above circumstances, one aspect of the present disclosure aims to enable a large number of users in locations other than the event location to participate in the production effects at the event location.

In order to solve the above problems, a production method according to one aspect of the present disclosure receives an action notification transmitted from each of a plurality of terminal devices in response to an action performed by a user, and controls the display mode of one or more production devices in a specific location in response to the number of times the action notification is received.

A control system according to one aspect of the present disclosure includes a receiving unit that receives an action notification transmitted from each of a plurality of terminal devices in response to an action performed by a user, and a control unit that controls the display mode of one or more performance devices in a specific location in response to the number of times the action notification is received.

A terminal device according to one aspect of the present disclosure includes an acquisition unit that acquires a set value, a receiving unit that receives from a control system a control value that increases over time according to the number of times that an action notification transmitted from each of a plurality of terminal devices in response to an action by a user is received, and a control unit that changes the display mode of a display device when the control value reaches the set value.

A: First embodiment Fig. 1 is a block diagram illustrating the configuration of a production system 100 according to a first embodiment. The production system 100 is a computer system for producing an event held in a facility 200. For example, various events such as a competitive event in which one or more athletes participate, or a music event in which one or more performers play or sing music, are held in the facility 200. The facility 200 in which the competitive event is held is, for example, a stadium or a gymnasium. The facility 200 in which the music event is held is, for example, an acoustic hall, a live music venue, or an outdoor stage.

An operator Ua and multiple visitors Ub are located within the facility 200. The operator Ua operates a service that uses the production system 100. The operator Ua uses a terminal device 10a. Each of the multiple visitors Ub watches an event held within the facility 200. Each visitor Ub uses a terminal device 10b. The terminal device 10b is used to produce the event within the facility 200. The terminal devices 10a and 10b are information devices such as mobile phones, smartphones, tablet terminals, or personal computers.

A plurality of viewers Uc are located outside the facility 200. Each viewer Uc is located, for example, at a location remote from the facility 200 (for example, at home). Each viewer Uc uses a playback device 400 and a terminal device 10c. The terminal device 10c is, for example, an information device such as a mobile phone, a smartphone, a tablet terminal, or a personal computer. Note that each viewer Uc may be located inside the facility 200.

The playback device 400 plays video content V that represents the status of an event held in the facility 200. The video content V is composed of video data representing video and audio data representing audio. The playback device 400 includes a display device that displays video represented by the video data and an audio output device that reproduces audio represented by the audio data (not shown). For example, a television receiver that reproduces a television program transmitted by airwaves as video content V is used as the playback device 400. In addition, an information terminal such as a smartphone or a tablet terminal is also used as the playback device 400. A large-scale video device (public viewing) that can be viewed by a large number of viewers Uc may be used as the playback device 400. Note that the video content V may be audio content (e.g., a radio program) composed only of audio data. In addition, a situation in which the terminal device 10c reproduces the video content V is also assumed. In other words, the playback device 400 is not essential for viewing the video content V.

The production system 100 includes a recording system 21, a distribution system 22, and a control system 30. The control system 30 is a computer system for controlling the production within the facility 200.

The recording system 21 records video of an event held within the facility 200. Specifically, the recording system 21 includes an imaging device that captures video of the event, and a sound collection device that collects the sound of the event (not shown). The recording system 21 generates a video composed of the video captured by the imaging device and the sound collected by the sound collection device.

The distribution system 22 distributes video content V, including the video recorded by the recording system 21, to each of the multiple playback devices 400. The distribution system 22 distributes the video content V in real time in parallel with the progress of the event in the facility 200 (i.e., live distribution). Each playback device 400 receives the video content V distributed by the distribution system 22 and plays the video content V in parallel with the progress of the event. The viewer Uc can grasp the status of the event in real time by watching the video content V played by the playback device 400.

Figure 2 is a block diagram illustrating the configuration of a terminal device 10 (10a, 10b, 10c). The terminal device 10 comprises a control device 11, a storage device 12, a communication device 13, an operation device 14, and a display device 15. The terminal device 10 may be realized as a single device, or may be realized as multiple devices configured separately from each other.

In the following description, when distinguishing between terminal device 10a, terminal device 10b, and terminal device 10c, the suffix a is added to the elements of terminal device 10a, the suffix b is added to the elements of terminal device 10b, and the suffix c is added to the elements of terminal device 10c. For example, the terminal device 10a used by the administrator Ua includes a control device 11a, a storage device 12a, a communication device 13a, an operation device 14a, and a display device 15a. The terminal device 10b used by the visitor Ub includes a control device 11b, a storage device 12b, a communication device 13b, an operation device 14b, and a display device 15b. The terminal device 10c used by the viewer Uc includes a control device 11c, a storage device 12c, a communication device 13c, an operation device 14c, and a display device 15c.

The control device 11 (11a, 11b, 11c) is composed of one or more processors that control each element of the terminal device 10. For example, the control device 11 is composed of one or more types of processors, such as a CPU (Central Processing Unit), an SPU (Sound Processing Unit), a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), or an ASIC (Application Specific Integrated Circuit).

The storage device 12 (12a, 12b, 12c) is a single or multiple memories that store the programs executed by the control device 11 and various data used by the control device 11. The storage device 12 is configured from a known recording medium, such as a magnetic recording medium or a semiconductor recording medium. The storage device 12 may also be configured from a combination of multiple types of recording media. The communication device 13 (13a, 13b, 13c) communicates with the control system 30 via a communication network 300, such as the Internet.

The operation devices 14 (14a, 14b, 14c) are input devices that accept instructions from users U (operator Ua, visitor Ub, viewer Uc). The operation devices 14 are, for example, multiple controls operated by the users U, or a touch panel that detects contact by the users U. The display devices 15 (15a, 15b, 15c) display images instructed by the control device 11. The display devices 15 are, for example, liquid crystal display panels or organic EL display panels.

Figure 3 is a block diagram illustrating the configuration of the control system 30. The control system 30 includes a control device 31, a storage device 32, and a communication device 33. The control system 30 may be realized as a single device, or as a collection of multiple devices configured separately from each other.

The control device 31 is composed of one or more processors that control each element of the control system 30. For example, the control device 31 is composed of one or more types of processors such as a CPU, SPU, DSP, FPGA, or ASIC. The storage device 32 is one or more memories that store the programs executed by the control device 31 and various data used by the control device 31. The storage device 32 is composed of a known storage medium such as a magnetic storage medium or a semiconductor storage medium. The storage device 32 may be composed of a combination of multiple types of storage media. The communication device 33 communicates with each of the multiple terminal devices 10 (10a, 10b, 10c) via the communication network 300.

Figure 4 is an explanatory diagram of the general operation of the performance system 100. Each of the multiple viewers Uc performs a predetermined operation (hereinafter referred to as an "instruction operation") on the operation device 14c of the terminal device 10c while watching the video content V played by the playback device 400. The instruction operation is, for example, a tap operation of touching the display surface of the display device 15c. The communication device 13c of the terminal device 10c transmits a notification A regarding the instruction operation (hereinafter referred to as an "action notification") to the control system 30. The action notification A is transmitted for each instruction action. That is, in parallel with the progress of the event in the facility 200, the action notification A is transmitted in parallel or sequentially from each of the multiple terminal devices 10c to the control system 30. The control system 30 receives the action notification A transmitted from the multiple terminal devices 10.

On the other hand, each of the multiple visitors Ub watches the event with the display device 15b of the terminal device 10b facing the location where the event will be held in the facility 200. For example, each visitor Ub maintains the display surface of the display device 15b facing the competition field where the competition event will be held, or the stage where the music event will be held. The display device 15b of each terminal device 10b displays a predetermined image (hereinafter referred to as a "performance image") 62. The performance image 62 in the first embodiment is an image that occupies most of the display surface of the display device 15b, and the display color is uniform throughout the entire image. By each display device 15b displaying (i.e. emitting light from) the performance image 62, a visual performance similar to the performance in which, for example, many spectators in the facility 200 emit light from their penlights is realized. The terminal device 10a is a device that allows the administrator Ua to instruct the start of the performance described above.

The control system 30 controls the display color of the performance image 62 in the multiple terminal devices 10b. The control system 30 of the first embodiment changes the performance image 62 in each of the multiple terminal devices 10b from an initial display color (hereinafter referred to as "initial color") C0 to a specific display color (hereinafter referred to as "target color") Ct. The initial color C0 of the performance image 62 is set individually for each terminal device 10b. Therefore, the initial color C0 of the performance image 62 differs between two or more terminal devices 10b in the facility 200. On the other hand, the target color Ct is common to the multiple terminal devices 10b.

The control system 30 of the first embodiment increases the number or percentage of terminal devices 10b whose performance images 62 change from the initial color C0 to the target color Ct (hereinafter referred to as "performance progress") over time in parallel with the progress of the event in the facility 200. That is, the display color of the performance image 62 in each terminal device 10b changes sequentially from the initial color C0 set individually for each terminal device 10b to a common target color Ct. That is, the display colors of the multiple performance images 62 are unified over time from multiple different initial colors C0 to a common target color Ct. The performance of changing the display color in each terminal device 10b from the initial color C0 to the target color Ct as in the above example is hereinafter referred to as "light performance operation". The terminal device 10b functions as a performance device for visual performance in the facility 200.

The control system 30 of the first embodiment controls the display color of the performance image 62 in each terminal device 10b according to the number of times (hereinafter referred to as the "number of receptions") N that the operation notification A is received from the multiple terminal devices 10c. Specifically, the performance progress increases over time according to the number of times N that the operation notification A is received. That is, the control system 30 controls the increase speed of the performance progress (e.g., the amount of increase per unit time) according to the number of receptions N. For example, the control system 30 controls the display color of the performance image 62 in the terminal device 10b so that the increase speed of the performance progress increases as the number of times N that the operation notification A is received increases. Therefore, the time required for the light performance operation changes according to the number of receptions N. For example, when the number of receptions N is large, the display color of all the performance images 62 changes to the target color Ct in a short time, and when the number of receptions N is small, the display color of all the performance images 62 changes to the target color Ct over a long time. As can be understood from the above explanation, each terminal device 10c is used so that the viewer Uc can participate in the light performance operation. Specific operations for realizing the light performance operation are described below. Each of the actions (Sa-Sd) illustrated below is executed in parallel with the progress of the event within the facility 200.

[Operation of terminal device 10a]
5 is a flowchart illustrating a specific procedure of a process (hereinafter referred to as a "management process") Sa executed by the control device 11a of the terminal device 10a used by the administrator Ua. The management process Sa is started in response to an instruction from the administrator Ua to the operation device 14a.

When the management process Sa is started, the control device 11a of the terminal device 10a causes the display device 15a to display the operation screen 40 of FIG. 6 (Sa1). The operation screen 40 is an image that allows the administrator Ua to specify the conditions for the light performance operation. Specifically, the operation screen 40 includes an operation image 41 (start), an operation image 42 (end), an operation image 43 (color selection), and an operation image 44. The operation image 41 is an image that allows the administrator Ua to instruct the start of the light performance operation. The operation image 42 is an image that allows the administrator Ua to instruct the end of the light performance operation.

The operation image 43 is an image for the administrator Ua to specify the target color Ct. That is, the administrator Ua selects the desired target color Ct by operating the operation image 43 using the operation device 14a. For example, a color symbolizing an athlete participating in a competitive event or a performer at a music event is specified as the target color Ct. In FIG. 6, it is assumed that the administrator Ua selects one of multiple colors prepared in advance. However, the method by which the administrator Ua specifies the target color Ct is not limited to the above example. For example, the administrator Ua may specify the target color Ct by inputting the component values of red (R), green (G), and blue (B).

The operation image 44 is an image that allows the operator Ua to indicate the shortest time T1 and the longest time T2. As mentioned above, the time required for the light performance operation changes depending on the number of receptions N. The shortest time T1 corresponds to the minimum value of the time required for the light performance operation, and is an example of the "first time." The longest time T2 corresponds to the maximum value of the time required for the light performance operation, and is an example of the "second time." The time required for the light performance operation is the length of time from when the performance image 62 of the initial color C0 is displayed on each terminal device 10b until the performance images 62 of all terminal devices 10b change to the target color Ct.

The control device 11a receives the selection of the target color Ct and instructions for the shortest time T1 and the longest time T2 from the administrator Ua (Sa2). The control device 11a also determines whether or not it has accepted the operation of the operation image 41 by the administrator Ua (Sa3). In other words, it determines whether or not the administrator Ua has issued an instruction to start the light performance operation. If the operation image 41 has not been operated (Sa3: NO), the control device 11a continues accepting instructions from the administrator Ua (Sa2).

On the other hand, if the operation image 41 is operated (Sa3: YES), the control device 11a transmits a start instruction Q1a from the communication device 13a to the control system 30 (Sa4). The start instruction Q1a is a message instructing the start of a light performance operation, and includes the target color Ct specified by the administrator Ua, and the shortest time T1 and longest time T2 specified by the administrator Ua.

When the start instruction Q1a is sent, the control device 11a waits until the operator Ua operates the operation image 42 (Sa5: NO). In other words, it is determined whether or not the operator Ua has instructed the end of the light performance operation. If the operation image 42 is operated (Sa5: YES), the control device 11a sends an end instruction Q2a from the communication device 13a to the control system 30 (Sa6). The end instruction Q2a is a message instructing the end of the light performance operation. The operation of the terminal device 10a is as described above. As can be understood from the above explanation, the terminal device 10a is used as an operation device for operating the light performance operation.

[Operation of control system 30]
FIG. 7 is a flowchart illustrating a specific procedure of the process Sd executed by the control device 31 of the control system 30 (hereinafter referred to as the "control process").

When the control process Sd is started, the control device 31 waits to receive a start instruction Q1a sent from the management terminal device 10a (Sd1: NO). When the start instruction Q1a is received by the communication device 33 (Sd1: YES), the control device 31 stores the target color Ct, shortest time T1, and longest time T2 included in the start instruction Q1a in the storage device 32 (Sd2). The control device 31 transmits a start instruction Q1b to each terminal device 10b and each terminal device 10c (Sd3). The start instruction Q1b is a message instructing the start of a light performance operation, and includes the target color Ct selected by the manager Ua. The terminal devices 10b and 10c to which the start instruction Q1b is to be sent are registered in advance in the storage device 32.

The control device 31 initializes the control value X to the minimum value xL (Sd4). The control value X is a variable for controlling the progress of the performance, and increases over time at a rate according to the number of times N that the action notification A has been received. The minimum value xL of the control value X is, for example, 0. After initializing the control value X, the control device 31 starts measuring the elapsed time t of the light performance action (Sd5). The elapsed time t is the length of time that has elapsed since the start of the light performance action.

The control device 31 receives the action notification A transmitted from each of the multiple terminal devices 10c by the communication device 33 (Sd6). That is, the control device 31 functions as a receiving unit that receives the action notification A transmitted from each of the multiple terminal devices 10c in response to an instruction action by the viewer Uc. The control device 31 counts the number of times N that the action notification A is received (Sd7). Specifically, the number of times that the action notification A is received within a unit period of a predetermined length is counted as the number of times N that the action notification A is received. The control device 31 updates the control value X in accordance with the number of times N that the action notification A is received (Sd8).

Figure 8 is an explanatory diagram of the change in control value X over time. The control device 31 updates the control value X so that it increases at a rate according to the number of receptions N. Specifically, the control value X is updated so that the rate at which the control value X increases increases as the number of receptions N increases. The rate at which the control value X increases is updated each time the number of receptions N is tallied (Sd7). Therefore, as shown by the dotted line in Figure 8, the control value X changes in a polygonal line shape over time t starting from the minimum value xL, and eventually reaches a predetermined maximum value xH. The maximum value xH is set to 100, for example.

The upper limit value EH(t) in FIG. 8 is a numerical value that changes over time over the shortest time T1 specified by the operator Ua. Specifically, the upper limit value EH(t) changes linearly from the minimum value xL to the maximum value xH over the shortest time T1. On the other hand, the lower limit value EL(t) is a numerical value that changes over time over the longest time T2 that is longer than the shortest time T1. Specifically, the lower limit value EL(t) changes linearly from the minimum value xL to the maximum value xH over the longest time T2. Therefore, the lower limit value EL(t) is lower than the upper limit value EH(t). Note that, in FIG. 8, an example is shown in which the upper limit value EH(t) changes linearly over time t, but the relationship between time t and the upper limit value EH(t) is not limited to the above example. For example, the upper limit value EH(t) may change in a curved or broken line shape over time t. Similarly, the relationship between time t and the lower limit value EL(t) is not limited to the linear relationship in FIG. 8. For example, the lower limit value EL(t) may change in a curved or broken line shape with respect to time t.

As can be seen from FIG. 8, the control device 31 changes the control value X within the range between the upper limit value EH(t) and the lower limit value EL(t) at the current time t. That is, if the control value X exceeds the upper limit value EH(t) when increased at an increase rate according to the number of receptions N, the control value X is set to the upper limit value EH(t). On the other hand, if the control value X falls below the lower limit value EL(t) when increased at an increase rate according to the number of receptions N, the control value X is set to the lower limit value EL(t). As can be seen from the above explanation, the time required for the control value X to change from the minimum value xL to the maximum value xH is a time in the range of the shortest time T1 or more and the longest time T2 or less.

When the control value X is updated, the control device 31 determines whether the communication device 33 has received an information request R from the terminal device 10b or terminal device 10c (Sd9). The information request R is a message requesting the control value X from the control system 30. If an information request R is received (Sd9: YES), the control device 31 transmits the control value X after the most recent update (Sd8) from the communication device 33 to the requesting terminal device 10b or terminal device 10c (Sd10). On the other hand, if the information request R is not received (Sd9: NO), the transmission of the control value X (Sd10) is not executed.

The control device 31 determines whether the communication device 33 has received an end instruction Q2a from the terminal device 10a of the operator Ua (Sd11). If the end instruction Q2a has not been received (Sd11: NO), the control device 31 transitions to step Sd6. That is, the reception and aggregation of the operation notification A (Sd6, Sd7), the update of the control value X (Sd8), and the transmission of the control value X to the terminal device 10b (Sd9, Sd10) are repeated until the end instruction Q2a is received.

When the communication device 33 receives the end instruction Q2a (Sd11: YES), the control device 31 transmits the end instruction Q2b to each terminal device 10b and each terminal device 10c (Sd12). The transmission of the end instruction Q2b terminates the control process Sd.

[Operation of terminal device 10c]
9 is a flowchart illustrating a specific procedure of a process (hereinafter referred to as a "participation process") Sc executed by the control device 11c of the terminal device 10c used by the viewer Uc. The participation process Sc is a process for the viewer Uc to participate in the light performance operation in the facility 200. The participation process Sc is started in response to an instruction from the viewer Uc to the operation device 14c.

When the participation process Sc is started, the control device 11c waits to receive a start command Q1b sent from the control system 30 (Sc1: NO). If the communication device 13c receives the start command Q1b (Sc1: YES), the control device 11c stores the target color Ct included in the start command Q1b in the storage device 12c (Sc2).

The control device 11c causes the display device 15c to display the operation image 51 (Sc3), as illustrated in FIG. 10. The operation image 51 is an image that allows the viewer Uc to instruct participation in the light performance operation. The control device 11c waits until the viewer Uc operates the operation image 51 (Sc4: NO). As explained above, the operation of the operation image 41 by the administrator Ua triggers each viewer Uc to be able to participate in the light performance operation.

When the operation image 51 is operated (Sc4: YES), the control device 11c causes the display device 15c to display an initial status image 52, as illustrated in FIG. 10 (Sc5). The status image 52 is an image that represents the progress of the light performance operation. Specifically, the status image 52 includes an effective area 53 displayed in the target color Ct. In the initial stage immediately after the participation process Sc is started, the effective area 53 is displayed in a small area.

The viewer Uc performs an instruction action (e.g., a tap operation) while viewing the situation image 52. The control device 11c judges whether the instruction action by the viewer Uc has been accepted by the operation device 14c (Sc6). If the instruction action has been accepted (Sc6: YES), the control device 11c transmits an action notification A, which signifies the acceptance of the instruction action, from the communication device 13c to the control system 30 (Sc7). As described above, the control system 30 receives the action notification A transmitted from each terminal device 10c (Sd6). On the other hand, if the instruction action is not accepted (Sc6: NO), the control device 11c does not transmit the action notification A (Sc7). As described above, an action notification A is transmitted to the control system 30 for each instruction action by the viewer Uc.

The control device 11c repeats the transmission of the operation notification A (Sc6, Sc7) until a predetermined time has elapsed since the display or update of the situation image 52 (Sc8: NO). When the predetermined time has elapsed (Sc8: YES), the control device 11c transmits an information request R from the communication device 13c to the control system 30 (Sc9). As described above, when the control system 30 receives the information request R from the terminal device 10c (Sd9: YES), it transmits the current control value X to the terminal device 10c (Sd10). The control device 11c of the terminal device 10c receives the control value X transmitted from the control system 30 by the communication device 13c (Sc10). That is, the control device 11c functions as a receiver that receives the control value X from the control system 30.

The control device 11c updates the situation image 52 according to the current control value X received from the control system 30 (Sc11). Specifically, as illustrated in FIG. 10, the control device 11c expands the area of the effective area 53 displayed in the target color Ct in the situation image 52 according to the control value X. The area of the effective area 53 expands over time as the control value X increases. In addition, when the control value X reaches a predetermined maximum value xH, the control device 11c causes the display device 15c to display a predetermined achievement image 54, as illustrated in FIG. 10. The achievement image 54 is an image that means that the performance progress has reached its maximum value.

After updating the situation image 52 (Sc11), the control device 11c judges whether the communication device 13c has received an end instruction Q2b from the control system 30 (Sc12). If the end instruction Q2b has not been received (Sc12: NO), the control device 11c transitions to step Sc6. That is, the transmission of an action notification A for each instruction action by the viewer Uc (Sc6, Sc7) and the updating of the situation image 52 according to the control value X (Sc8 to Sc11) are repeated until the end instruction Q2b is received. The participation process Sc ends when the end instruction Q2b is received (Sc12: YES).

[Operation of terminal device 10b]
FIG. 11 is a flow chart illustrating a specific procedure of a process (hereinafter referred to as a "performance process") Sb executed by the control device 11b of the terminal device 10b used by the visitor Ub in the facility 200. The performance process Sb is started when the visitor Ub gives an instruction to the operation device 14b. It is also assumed that the user U (visitor Ub or viewer Uc) can select whether the terminal device 10 executes the participation process Sc or the performance process Sb. When the participation process Sc is selected, the terminal device 10 is used as the terminal device 10c for the viewer Uc, and when the performance process Sb is selected, the terminal device 10 is used as the terminal device 10b for the visitor Ub. That is, the user U can select whether the terminal device 10 is used as the terminal device 10b for performance or the terminal device 10c for viewing.

When the performance process Sb is started, the control device 11b waits to receive a start command Q1b sent from the control system 30 (Sb1: NO). If the communication device 13b receives the start command Q1b (Sb1: YES), the control device 11b stores the target color Ct included in the start command Q1b in the storage device 12b (Sb2).

As shown in FIG. 12, the control device 11b causes the display device 15b to display an operation image 61 (Sb3). The operation image 61 is an image that allows the visitor Ub to instruct his/her participation in the light performance operation. The control device 11b waits until the viewer Uc operates the operation image 61 (Sb4: NO). As explained above, the operation of the operation image 41 by the administrator Ua triggers each visitor Ub to be able to participate in the light performance operation.

When the operation image 61 is operated (Sb4: YES), the control device 11b sets the initial color C0 (Sb5). For example, the control device 11b randomly selects one of multiple colors as the initial color C0. Specifically, the control device 11b generates, for example, a uniformly distributed random number, and sets the color corresponding to the random number from among the multiple colors as the initial color C0. As illustrated in FIG. 12, the control device 11b displays the performance image 62 of the initial color C0 on the display device 15b (Sb6). As described above, the initial color C0 is set individually for each terminal device 10b, so that the initial color C0 differs for two or more terminal devices 10b in the facility 200, as illustrated in FIG. 4.

The control device 11b also sets a set value Y (Sb7). The set value Y is set to a numerical value within the range of the minimum value xL to the maximum value xH of the control value X (xL≦Y≦xH). The control device 11b randomly selects a numerical value within the range of the minimum value xL to the maximum value xH as the set value Y. Specifically, the control device 11b sets a random number generated by uniform distribution within the range of the minimum value xL to the maximum value xH as the set value Y. As described above, the set value Y is set randomly for each terminal device 10b, so that the set value Y differs for two or more terminal devices 10 in the facility 200.

The control device 11b waits until a predetermined time has elapsed (Sb8). When the predetermined time has elapsed (Sb8: YES), the control device 11b transmits an information request R from the communication device 13b to the control system 30 (Sb9). As described above, when the control system 30 receives the information request R from the terminal device 10b (Sd9: YES), it transmits the current control value X to the terminal device 10b (Sd10). The control device 11b of the terminal device 10b receives the control value X transmitted from the control system 30 via the communication device 13b (Sb10).

The control device 11b determines whether the current control value X received from the control system 30 exceeds the set value Y (Sb11). If the control value X is below the set value Y (Sb11: NO), the control device 11b transitions to step Sb8. That is, the acquisition of the latest control value X (Sb9, Sb10) and the comparison of the control value X with the set value Y (Sb11) are repeated at predetermined time intervals.

When the control value X exceeds the set value Y (Sb11: YES), the control device 11b changes the display color of the performance image 62 displayed on the display device 15b to the target color Ct stored in the storage device 12b (Sb12), as illustrated in FIG. 12. That is, when the control value X, which increases over time, reaches the set value Y, the display color of the performance image 62 changes from the initial color C0 to the target color Ct. As can be understood from the above explanation, the operation of the control device 31 of the control system 30 transmitting the control value X to each terminal device 10b (Sd10) realizes a control unit that controls the display color of the multiple terminal devices 10b in the facility 200 according to the number of receptions N. In addition, the control device 11b of the terminal device 10b functions as a control unit that changes the display mode of the display device 15b. Note that, when the control value X and the set value Y are equal, either the transition to step Sb8 or the update of the performance image 62 (Sb12) may be executed.

As mentioned above, the setting value Y is set individually for each terminal device 10b. On the other hand, the control value X is common to multiple terminal devices 10b. Therefore, the time when the display color of the performance image 62 changes from the initial color C0 to the target color Ct differs for each terminal device 10b. That is, the ratio of terminal devices 10b in which the display color of the performance image 62 has changed to the target color Ct among the multiple terminal devices 10b in the facility 200 (i.e., the performance progress degree) increases over time as the control value X increases, and eventually the performance images 62 of all terminal devices 10b change to the target color Ct. Since the increase speed of the control value X is controlled according to the number of times N that the action notification A is received, the performance progress degree also increases over time at a speed according to the number of times N that the action notification A is received. In other words, the time when the display color of the performance image 62 in each terminal device 10b changes from the initial color C0 to the target color Ct is controlled according to the number of times N that the action notification A is received.

As can be understood from the above explanation, during the light performance operation, among the multiple terminal devices 10b in the facility 200, a number or ratio of terminal devices 10b corresponding to the control value X display the target color Ct. In other words, the control value X is essentially regarded as the performance progress degree. As described above, the control value X changes over time within a range between an upper limit value EH(t) that changes over time over the shortest time T1 and a lower limit value EL(t) that changes over time over the longest time T2. Therefore, the performance progress degree changes over time between a maximum value that changes over time over the shortest time T1 and a minimum value that changes over time over the longest time T2.

As described above, the time until the display color of the effect image 62 in all terminal devices 10b changes to the target color Ct is limited to a range of at least the shortest time T1 and at most the longest time T2. This prevents all effect images 62 from changing to the target color Ct in an excessively short time that falls short of the shortest time T1, or prevents an excessively long time that exceeds the longest time T2 from passing before the display color of all effect images 62 changes to the target color Ct.

As described above, in the first embodiment, the display color of the performance image 62 on the multiple terminal devices 10b in the facility 200 is controlled according to the number of times N that the operation notification A transmitted from the multiple terminal devices 10c is received. Therefore, a viewer Uc who is outside the facility 200 can participate in the visual performance effect within the facility 200. In the first embodiment, the display color of the performance image 62 on the multiple terminal devices 10b in the facility 200 changes to a common target color Ct, so that an effective performance with a sense of visual unity or togetherness can be realized. Each viewer Uc can also confirm the progress of the light performance operation within the facility 200 by watching the video content V that records the situation within the facility 200.

In the first embodiment, the performance progress degree, which is the number or percentage of terminal devices 10b among the multiple terminal devices 10b in which the display color of the performance image 62 has changed to the target color Ct, increases over time according to the number of receptions N. Therefore, multiple viewers Uc outside the facility 200 can be involved in the rate at which the performance progress degree increases within the facility 200.

In addition, in the first embodiment, when the control value X that each of the multiple terminal devices 10b acquires from the control system 30 reaches the setting value Y set for each terminal device 10b, the display color of the performance image 62 in that terminal device 10b changes to the target color Ct. This has the advantage that the control system 30 does not need to manage the display color of the performance image 62 in each of the multiple terminal devices 10b.

When the administrator Ua instructs the terminal device 10a, each terminal device 10c starts sending an operation notification A (Sc7) and each terminal device 10b starts controlling the display color (Sb12). This makes it possible to avoid a situation in which a light performance operation starts at an inappropriate time for an event in progress within the facility 200.

B: Second embodiment A second embodiment will be described. Note that, for elements in the following exemplary aspects that have the same functions as those in the first embodiment, the same reference numerals as those in the first embodiment will be used, and detailed descriptions of each will be omitted as appropriate.

Figure 13 is a block diagram illustrating the configuration of a production system 100 according to the second embodiment. The production system 100 of the second embodiment includes a sound emission system 25 in addition to the same elements as in the first embodiment. The sound emission system 25 is an acoustic system composed of audio equipment installed in the facility 200, and emits sound within the facility 200. The sound emission system 25 includes, for example, multiple sound emission devices installed in different locations within the facility 200.

The control system 30 of the second embodiment controls the light production operation as in the first embodiment, and also causes the sound emission system 25 to emit various sound effects. The sound effects are sounds for production related to the event. For example, the singing sounds and instrument sounds of cheering songs for the participants of a competitive event, the cheers of many spectators, the applause sounds generated by the applause of the spectators, the sigh sounds of many spectators when disappointed, etc. are exemplified as sound effects. The control system 30 selectively causes the sound emission system 25 to emit one of a plurality of sound effects. For example, the control system 30 transmits one of a plurality of sound data representing waveforms of different sound effects to the sound emission system 25, and the sound emission system 25 emits a sound effect corresponding to the sound data. By emitting sound effects in the facility 200, an atmosphere as if a large number of spectators were watching can be created in the facility 200, even in a situation where there are few visitors Ub. The control system 30 may be composed of a device that controls the light performance operation and a device that controls the emission of sound effects.

Figure 14 is a schematic diagram of a selection screen 70 displayed by the display device 15c of the terminal device 10c used by the viewer Uc. The selection screen 70 is an image for the viewer Uc to select one of a number of types of sound effects. Specifically, a number of operation images 71 corresponding to different sound effects are arranged on the selection screen 70. Each operation image 71 is a software button that the viewer Uc can operate using the operation device 14c. "Cheer song" in Figure 14 refers to the vocal sounds and instrumental sounds of a cheer song for the participants of a competitive event. "Cheers" refers to the cheering sounds made by the spectators at a competitive event. "Applause" refers to the applause sounds made by the spectators' applause. "Disappointment" refers to the sighing sounds made by the spectators when they are disappointed.

The viewer Uc can select one of a number of sound effects from the selection screen 70 by operating the operation device 14c while watching the video content V. The control device 11c of the terminal device 10c transmits a selection notification B, which specifies the sound effect selected by the viewer Uc, from the communication device 13c to the control system 30.

When the terminal device 10c receives the start instruction Q1b sent by the control system 30 (Sc1), the control device 11c causes the display device 15c to display the operation image 51 so as to overlap the selection screen 70, as illustrated in FIG. 14 (Sc3). Note that before the start instruction Q1b is received (Sc1: NO), the multiple operation images 71 are displayed on the display device 15c, but the operation image 51 is not displayed. In other words, upon receiving the start instruction Q1b, the state in which the selection of a sound effect by the viewer Uc is accepted transitions to a state in which the selection of a sound effect and an instruction to participate in the light performance operation are accepted.

Figure 15 is a flow chart illustrating the specific steps of the process Se (hereinafter referred to as "sound emission process") for controlling the emission of sound effects by the control system 30 of the second embodiment. The control device 31 of the control system 30 executes the sound emission process Se in parallel with the control process Sd (Figure 7) similar to that of the first embodiment. In other words, the sound emission process Se is executed in parallel with the progress of the event in the facility 200. The sound emission process Se is repeated at a predetermined cycle.

When the sound emission process Se is started, the control device 31 receives the selection notification B sent from each terminal device 10c via the communication device 33 (Se1). The control device 31 counts the sound effects specified by each selection notification B to calculate the number of selections M for each of the multiple sound effects (Se2). The number of selections M for each sound effect is the number of times that sound effect has been selected by multiple viewers Uc.

The control device 31 selects one of the multiple sound effects according to the number of times M each sound effect has been selected (Se3). For example, the control device 31 selects the sound effect with the largest number of times M selected from the multiple sound effects (hereinafter referred to as the "selected sound effect"). The control device 31 causes the sound emission system 25 to emit the selected sound effect (Se4). For example, the control device 31 causes the sound emission system 25 to emit the selected sound effect by supplying audio data of the selected sound effect to the sound emission system 25. Note that the control device 31 may adjust the volume of the selected sound effect by processing the audio data according to the number of times M the selected sound effect has been selected. For example, a configuration is envisioned in which the volume of the selected sound effect increases as the number of times M selected increases.

The second embodiment achieves the same effects as the first embodiment. Furthermore, in the second embodiment, sound effects are emitted in addition to the light production operation, so that both visual and auditory production effects can be achieved within the facility 200. Furthermore, multiple viewers Uc can participate in both the visual and auditory production effects.

C: Third embodiment FIG. 16 is a schematic diagram of an operation screen 40 displayed on the display device 15a of the terminal device 10a in the third embodiment. The operation screen 40 of the third embodiment includes an operation image 46 (instant change) in addition to elements similar to those of the operation screen 40 of the first embodiment illustrated in FIG. 6. As described above, the light performance operation gradually progresses over a period of time that is greater than or equal to the shortest time T1 and less than or equal to the longest time T2. The operation image 46 in FIG. 16 is an image for the operator Ua to immediately and forcibly end the light performance operation. When the operator Ua operates the operation image 46, the control device 11a of the terminal device 10a transmits an immediate end instruction from the communication device 13a to the control system 30.

Figure 17 is a flow chart illustrating a part of the control process Sd in the third embodiment. When the control value X is updated in the same procedure as in the first embodiment (Sd8), the control device 31 judges whether or not the communication device 33 has received an immediate termination instruction from the terminal device 10a (Sd21). If an immediate termination instruction has been received (Sd21: YES), the control device 31 sets the control value X to the maximum value xH (Sd22). On the other hand, if an immediate termination instruction has not been received (Sd21: NO), the process of setting the control value X to the maximum value xH is not executed. As in the first embodiment, the control device 31 transmits the control value X to the terminal device 10b or the terminal device 10c (Sd9, Sd10).

When the control value X is set to the maximum value xH, the control value X naturally exceeds the set value Y set for each terminal device 10b (Sb11). That is, the result of the judgment in step Sb11 in the performance process Sb (FIG. 11) is positive (Sb11: YES). Therefore, in all terminal devices 10b in which the performance image 62 has not been changed to the target color Ct, the display color of the performance image 62 is changed to the target color Ct. That is, the light performance operation is forcibly progressed to the final state. Furthermore, by setting the control value X to the maximum value xH, the achievement image 54 is displayed in the terminal device 10c.

The third embodiment also achieves the same effect as the first embodiment. In addition, in the third embodiment, the operator Ua can immediately and forcibly end the light performance operation. The configuration of the second embodiment in which the sound emission system 25 emits sound effects may be applied to the third embodiment. In the above description, the light performance operation is ended by setting the control value X to the maximum value xH, but the control device 31 of the control system 30 may send instruction data to each terminal device 10b and each terminal device 10c to end the light performance operation. When the control device 11b of the terminal device 10b receives instruction data from the control system 30, it changes the display color of the performance image 62 to the target color Ct. When the control device 11c of the terminal device 10c receives instruction data from the control system 30, it causes the display device 15c to display the achievement image 54.

D: Modifications Specific modifications to the above-mentioned embodiments are illustrated below. Multiple embodiments selected from the following examples may be combined as appropriate to the extent that they are not mutually contradictory.

(1) In each of the above-mentioned embodiments, the display color of the display device 15b is changed to the target color Ct, but the display mode that is changed according to the number of times N of receiving the action notification A is not limited to the display color. In other words, as long as the display mode is controlled according to the number of times N of receiving the action notification A, the type of the display mode is arbitrary. "Display mode" means a display characteristic that can be visually distinguished by an observer. For example, in addition to the display colors exemplified in each of the above-mentioned embodiments, the concept of "display mode" includes the pattern (design) or shape of the performance image 62. Note that the "display color" is defined by hue (tone), saturation, or brightness (gradation). One or more of the display modes exemplified above are controlled according to the number of times N of receiving the action notification A. The process of changing the display color of the performance image 62 from the initial color C0 to the target color Ct is comprehensively expressed as a process of changing the display mode of the terminal device 10b from an initial display mode (initial mode) to a target display mode (target mode). In each of the above-mentioned embodiments, an example is given in which the overall display color of the effect image 62 changes, but embodiments in which the display mode of only a portion of the effect image 62 changes are also envisioned.

(2) In each of the above-mentioned embodiments, the terminal device 10b used by the visitor Ub is exemplified as a device for effecting (hereinafter referred to as a "effecting device"), but the effecting device is not limited to the above-mentioned examples. For example, a lighting device with a variable emission color may be used as the effecting device. The lighting device is equipped with a portable (e.g., penlight-type) light-emitting body capable of communicating with the control system 30. The emission color of the lighting device changes from the initial color C0 to the target color Ct by the same operation as the terminal device 10b in each of the above-mentioned embodiments. In addition, for example, a display device installed in the facility 200 may be used as the effecting device. The display device is a large display body (e.g., a back screen installed in a baseball field) capable of communicating with the control system 30. The display color of the display device changes from the initial color C0 to the target color Ct by the same operation as the terminal device 10b in each of the above-mentioned embodiments. As can be understood from the above explanation, the effecting device is any device capable of changing the display mode. In addition, in a configuration in which a lighting device is used as a effecting device, the emission color or the amount of emission is included in the concept of "display mode".

(3) In each of the above-described embodiments, a tap operation on the display surface of the display device 15c is exemplified as an instruction action, but the instruction action is not limited to the above examples. For example, a flick operation or a double tap operation on the display surface of the display device 15c, or an action of pressing an operator provided on the operation device 14c are also included in the "instruction action". Furthermore, the instruction action is not limited to an action detected by the operation device 14c. For example, an action of the viewer Uc detected by a detection device other than the operation device 14c (for example, an acceleration sensor) is also included in the "instruction action". For example, the detection device may detect an action of the viewer Uc shaking the terminal device 10c as an "instruction action".

(4) In each of the above-mentioned embodiments, the display color of the effect image 62 is switched from the initial color C0 to the target color Ct, but the manner in which the display color changes is not limited to the above examples. For example, the display color of the effect image 62 may change stepwise or continuously from the initial color C0 to the target color Ct. Specifically, a configuration is envisaged in which the display color of the effect image 62 is multi-value controlled according to the control value X within the range between the initial color C0 and the target color Ct. The speed at which the display color of the effect image 62 changes from the initial color C0 to the target color Ct may be controlled according to the number N of times the action notification A is received.

(5) In each of the above-mentioned embodiments, the display color of the performance image 62 in each terminal device 10b is changed from the initial color C0 to the target color Ct at a time point corresponding to the number of times N of reception of the action notification A, but the relationship between the number of times N of reception and the display mode of the terminal device 10b is not limited to the above examples. For example, the brightness or saturation of the performance image 62 in each terminal device 10b may be controlled according to the number of times N of reception. For example, a configuration is assumed in which the brightness or saturation of the performance image 62 in each terminal device 10b is increased as the number of times N of reception increases. In addition, the display mode of the performance image 62 in each terminal device 10b may be changed at a frequency corresponding to the number of times N of reception. It does not matter whether the time point at which the display mode of the performance image 62 changes in the multiple terminal devices 10b is the same. As can be understood from the above examples, "controlling the display mode according to the number of times N of reception" means that the display mode in the terminal device 10b changes in conjunction with the change in the number of times N of reception. That is, a configuration is assumed in which the change in the display mode (e.g., the conditions for the change) differs when the number of receptions N is a first value and when the number of receptions N is a second value other than the first value. In other words, a configuration in which the change over time in the performance progress degree when the number of receptions N is a first value differs from the change over time in the performance progress degree when the number of receptions N is a second value.

For example, in each of the above-mentioned embodiments, the rate at which the control value X (performance progress) increases is controlled according to the number of times N that the action notification A is received, but the relationship between the number of times N and the control value X is not limited to the above examples. Specifically, a configuration in which the control value X increases at a frequency according to the number of times N that the action notification A is received is also envisioned.

(6) In each of the above-mentioned embodiments, the display color of the effect image 62 in each terminal device 10b changes to a target color Ct common to the multiple terminal devices 10b. However, it is not essential that the final display state of the effect image 62 is common to the multiple terminal devices 10b. For example, contrary to the above-mentioned embodiments, a form in which the display color of the effect image 62 changes from an initial color C0 common to the multiple terminal devices 10b to a target color Ct set individually for each terminal device 10b is also envisioned.

(7) In the above embodiments, the initial color C0 of the effect image 62 is set individually by each terminal device 10b, but the control system 30 may set the initial color C0 centrally for each of the multiple terminal devices 10b. For example, the control device 31 of the control system 30 selects one of multiple display colors as the initial color C0 for each of the multiple terminal devices 10b and notifies each terminal device 10b of the initial color C0. With the above configuration, it is possible to appropriately distribute the initial color C0 of the effect image 62 among the multiple terminal devices 10b.

In addition, in each of the above-mentioned embodiments, the setting value Y is set individually by each terminal device 10b, but the control system 30 may centrally set the setting value Y for each of the multiple terminal devices 10b. For example, the control device 31 of the control system 30 sets different setting values Y for each of the multiple terminal devices 10b and notifies each terminal device 10b of the setting value Y. The control device 11b of each terminal device 10b receives the setting value Y by the communication device 13b. The specific process in which the setting value Y is applied is the same as in the first embodiment. According to the above configuration, it is possible to appropriately distribute the setting value Y among the multiple terminal devices 10b. That is, it is possible to appropriately distribute the time at which the display color of the performance image 62 changes from the initial color C0 to the target color Ct among the multiple terminal devices 10b. As can be understood from the above explanation, the control device 11b of the terminal device 10b functions as an element (acquisition unit) that acquires the setting value Y. The acquisition unit includes both an element that sets the set value Y as illustrated in the first embodiment, and an element that receives the set value Y from the control system 30.

(8) In each of the above-described embodiments, a large-area image in which the display color is uniform across the entire image is exemplified as the performance image 62, but the performance image 62 is not limited to the images exemplified above. For example, any image can be used as the performance image 62, such as an image in which the display color differs for each region, or an image that includes various patterns such as geometric patterns.

(9) In each of the above-mentioned embodiments, when the control value X, which increases over time, exceeds the set value Y for each terminal device 10b, the terminal device 10b changes the display color of the performance image 62 from the initial color C0 to the target color Ct. However, the specific configuration and method for changing the display color of the performance image 62 in each terminal device 10b are not limited to the above examples. For example, an instruction to change the display color of the performance image 62 from the initial color C0 to the target color Ct (hereinafter referred to as a "change instruction") may be sent from the control system 30 to each terminal device 10b. Specifically, the control device 31 of the control system 30 selects each of the multiple terminal devices 10b in sequence so that the performance progress increases over time according to the number of receptions N, and transmits the change instruction to each selected terminal device 10b. When the communication device 13b receives the change instruction from the control system 30, each terminal device 10b changes the display color of the performance image 62 from the initial color C0 to the target color Ct.

(10) In each of the above-described embodiments, the user U selects whether to use the terminal device 10 as the terminal device 10b for performance or the terminal device 10c for viewing. However, a configuration is also envisioned in which the terminal device 10 located within the facility 200 operates as the terminal device 10b for performance and the terminal device 10 not located within the facility 200 operates as the terminal device 10c for viewing.

For example, a wireless transmission device is installed in the facility 200. The wireless transmission device transmits confirmation data indicating that the terminal device 10 is located in the facility 200 to the facility 200 by short-range wireless communication. That is, the terminal device 10 located in the facility 200 can receive the confirmation data, but the terminal device 10 located outside the facility 200 cannot receive the confirmation data. The terminal device 10 that receives the confirmation data operates as the terminal device 10b for performance, and the terminal device 10 that cannot receive the confirmation data operates as the terminal device 10c for viewing. The short-range wireless communication performed by the wireless transmission device is, for example, wireless communication such as Bluetooth (registered trademark) or Wi-Fi (registered trademark), or acoustic communication using sound as a transmission medium. In a configuration in which the confirmation data is transmitted by acoustic communication, for example, a sound emitting device that emits a guidance voice in the facility 200 is used as the wireless transmission device. In addition, the terminal device 10 that reads the QR code (registered trademark) posted in the facility 200 may be operated as the terminal device 10b for performance.

(11) Although competitive events and music events have been exemplified in each of the above-mentioned forms, the events to which each of the above-mentioned forms apply are not limited to these examples. For example, each of the above-mentioned forms applies to various events held for a specific purpose, such as dance events where dancers dance, theater events where actors perform, lecture events where speakers give lectures, and educational events where various educational institutions such as schools and cram schools provide lessons to students.

(12) As described above, the functions of the control system 30 exemplified above are realized by the cooperation of one or more processors constituting the control device 31 and the programs stored in the storage device 32. In addition, the functions of each terminal device 10 (10a, 10b, 10c) are realized by the cooperation of one or more processors constituting the control device 11 and the programs stored in the storage device 12.

The above-mentioned programs can be provided in a form stored in a computer-readable recording medium and installed in a computer. The recording medium is, for example, a non-transitory recording medium, and a good example is an optical recording medium (optical disk) such as a CD-ROM, but also includes any known type of recording medium such as a semiconductor recording medium or a magnetic recording medium. Note that a non-transitory recording medium includes any recording medium other than a transient, propagating signal, and does not exclude volatile recording media. In addition, in a configuration in which a distribution device distributes a program via a communication network, the recording medium that stores the program in the distribution device corresponds to the non-transitory recording medium described above.

E: Supplementary Note From the above-described exemplary embodiments, the following configurations, for example, can be understood.

A production method according to one aspect (aspect 1) of the present disclosure receives an action notification transmitted from each of a plurality of terminal devices in response to an action by a user, and controls the display mode of one or more production devices in a specific location in response to the number of times the action notification is received. In the above aspect, the display mode of the production device in the specific location is controlled in response to the number of times the action notification transmitted from the plurality of terminal devices is received. Therefore, for example, a user of a terminal device located in a location other than the specific location can participate in the visual production effect in the specific location.

In a specific example (Aspect 2) of Aspect 1, the one or more production devices are multiple production devices, and in controlling the display mode, the display mode of each of the multiple production devices is changed to a common target mode. In the above aspect, the display modes of multiple production devices in a specific location change to a common target mode. Therefore, an effective production that creates a sense of visual unity or togetherness can be realized. Note that it does not matter whether the time at which the display mode changes to the target mode in each of the multiple production devices is the same.

In a specific example (Aspect 3) of Aspect 2, in controlling the display mode, the display mode of each of the multiple production devices is controlled so that the performance progress degree, which is the number or percentage of the multiple production devices whose display mode has changed to the target mode, increases over time according to the number of times the operation notification is received. In the above aspect, the performance progress degree, which is the number or percentage of the multiple production devices whose display mode has changed, increases over time according to the number of times the operation notification is received. Therefore, the user of the terminal device can be involved in the rate at which the performance progress degree increases in a specific location.

The relationship between the number of times an action notification is received and the performance progress level is arbitrary. For example, a configuration is envisioned in which the performance progress level monotonically increases as the number of times an action notification is received increases. It is not necessary for the performance progress level to be linked to the number of times the notification is received throughout the entire range of the numerical value of the number of times it is received. For example, a configuration is also envisioned in which the performance progress level does not change in response to changes in the number of times it is received within a specific range.

In a specific example of aspect 3 (aspect 4), in controlling the display aspect, the display aspect of each of the multiple production devices is controlled so that the rate at which the performance progress degree increases changes according to the number of times the notification is received. In the above aspect, the rate at which the overall display aspect across the multiple production devices changes to the target aspect can be controlled. For example, a configuration is envisaged in which the rate at which the performance progress degree increases increases as the number of times the action notification is received increases. Note that the rate at which the performance progress degree increases refers to the rate at which the performance progress degree increases over time (the amount of increase per unit time).

In a specific example (Aspect 5) of Aspect 3 or Aspect 4, in controlling the display mode, the display mode of each of the multiple production devices is controlled so that the performance progress changes within a range between a maximum value that changes over time over a first time and a minimum value that changes over time over a second time that is longer than the first time. In the above aspect, the time until the display modes of all of the multiple production devices change to the target mode can be limited to a range of at least the first time and at most the second time. In other words, it is possible to change the display modes of the multiple production devices to the target mode over an appropriate amount of time, at least the first time and at most the second time. For example, it is possible to prevent the display modes of all of the production devices from changing to the target mode in an excessively short time, or to prevent an excessively long time from elapsed until the display modes of all of the production devices change to the target mode.

In a specific example (Aspect 6) of any of Aspects 2 to 5, each of the multiple production devices sets a setting value, and in controlling the display mode, a control system that receives the operation notification from each of the multiple terminal devices increases a control value over time according to the number of times the notification is received, and each of the multiple production devices acquires the control value from the control system and changes the display mode when the control value reaches the setting value set for that production device. In the above aspects, when the control value acquired by each of the multiple production devices from the control system reaches the setting value set for each production device, that production device changes the display mode. Therefore, there is no need for the control system to know the display mode of each of the multiple production devices.

In a specific example (Aspect 7) of any of Aspects 1 to 6, an instruction from the operator to the management device is triggered to cause each of the multiple terminal devices to start transmitting an operation notification and to start controlling the display mode of the one or more production devices. In the above aspects, an instruction from the operator to the management device is triggered to cause each terminal device to start transmitting an operation notification and to start controlling the display mode of the production device. This makes it possible to avoid a situation in which the display mode of the production device changes at an inappropriate time.

A control system according to one aspect (aspect 8) of the present disclosure includes a receiving unit that receives an action notification transmitted from each of a plurality of terminal devices in response to an action by a user, and a control unit that controls the display mode of one or more performance devices in a specific location in response to the number of times the action notification is received. Also, a terminal device according to one aspect (aspect 9) of the present disclosure includes an acquisition unit that acquires a setting value, a receiving unit that receives from the control system a control value that increases over time in response to the number of times the action notification transmitted from each of a plurality of terminal devices in response to an action by a user is received, and a control unit that changes the display mode of the display device when the control value reaches the setting value.
