JP 2004-318503 A

However, the behavior management support system disclosed in Patent Document 1 notifies the user of messages that include direct instructions, which may cause some users to feel a sense of obligation and stress as a result.

This disclosure has been made to solve the problems described above, and provides a behavioral support system that can encourage users to take voluntary action.

The behavioral support system according to the present disclosure is a behavioral support system that supports a user's activity, and includes a detection device that detects the user's condition, a projection device that displays or illuminates an image, and a control device that controls the projection device to display or illuminate an image related to an action item defined in accordance with the activity to be supported based on the results detected by the detection device, and when the action item is eating, the control device analyzes the eating pace from the results detected by the detection device and controls the projection device to change the color or brightness of the lighting in accordance with the eating pace, and when the user's eating pace is faster than a threshold value, controls the projection device to fluctuate the illuminance and color temperature of the lighting .

The behavior support system disclosed herein displays an image or illuminates the screen when the behavior item is eating, based on the results of detection by the detection device. This makes it possible to indirectly encourage the user to perform a specific activity without directly instructing the user to do so. This makes it possible to encourage the user to be more spontaneous in their activities.

Embodiment 1.
The action support system 1 of the first embodiment will be described with reference to the drawings. The action support system 1 is installed in, for example, a facility for elderly people. In this case, elderly people staying at the facility correspond to users of the action support system 1. The action support system 1 supports users to perform activities defined as action items. The action items are activities performed in daily life by users staying at the facility classified as items, such as walking, exercise, climbing stairs, eating, conversation, hobbies, bathing, getting up, and going to bed. In other words, the action items are defined corresponding to the activities to be supported. The action support system 1 supports users to perform at least one activity defined as an action item according to the type of the facility.

FIG. 1 is a schematic diagram showing a behavior support system 1 according to the first embodiment. As shown in FIG. 1, the behavior support system 1 has a detection device 11, a projection device 12, and a control device 13. The control device 13 is connected to the detection device 11 and the projection device 12 so as to be able to communicate with each other via wire or wirelessly.

Detection device 11 is a general term for a device that detects the presence or state of a user, such as their actions. Various types of detection device 11 are used, such as beacons, motion detection devices, infrared sensors, sound sensors, and sleep sensors. Detection devices 11 are installed at multiple locations within the facility according to the activities defined as action items. The specific devices adopted as detection devices 11 and the locations at which they are installed are determined based on the type of action item and the state of each action item. Details of specific devices will be described later for each action item.

Projection device 12 is a general term for a device that projects images or light, that is, displays images or provides illumination. Various types of projection devices 12 are used, such as projectors, displays, and lighting equipment. Projection devices 12 are installed at multiple locations within the facility depending on the activities defined as action items. The specific devices used as projection devices 12 and the locations at which they are installed are determined based on the type of action item and the state of each action item. Details of the specific devices will be described later in conjunction with the explanation of detection device 11 for each action item.

The control device 13 is, for example, a server device having a CPU (Central Processing Unit, also called a central processing unit, processing device, arithmetic device, microprocessor, or processor). The control device 13 is installed in a room in the facility or outside the facility. The control device 13 centrally manages and controls the detection device 11 and the projection device 12. In detail, the control device 13 controls the projection device 12 so as to display or illuminate an image related to an action item based on the result detected by the detection device 11. In addition, the control device 13 controls the projection device 12 based on the result detected by the detection device 11 when the user is performing an activity defined as an action item. In other words, the specific content of the image or the lighting method is changed according to the action performed by the user. Note that the lighting method here means the lighting mode determined by the dimming and color adjustment settings, the lighting direction, etc.

The control device 13 has a control unit and a memory unit 22. Each function of the control unit is realized by software, firmware, or a combination of software and firmware. The software and firmware are written as programs and stored in the memory unit 22.

The control unit has a type determination unit 31, an analysis unit 32, and a first output unit 33. The type determination unit 31 determines the type of the action item that the user is about to perform based on the detection result of the detection device 11. That is, the type determination unit 31 determines which action item of the multiple pre-set action items the user's activity corresponds to based on the detection result of the detection device 11. Note that, if only one action item is set, the type determination unit 31 determines whether the user's activity corresponds to the action item. After the action item is determined, the analysis unit 32 analyzes the detection result of the detection device 11 and measures the user's actions and the surrounding environment, etc. The method of analyzing the user's actions and the surrounding environment, etc. is a well-known video analysis method, so the explanation is omitted. The first output unit 33 generates video data or a lighting control signal to be displayed on the projection device 12 based on the measurement result of the analysis unit 32, and outputs it to the projection device 12. Note that the video data is output data that determines the content of the specific video. In addition, the specific operation of the control unit is determined based on the state of each action item. The specific operation of the control unit will be described later for each action item along with an explanation of the detection device 11 and projection device 12.

The storage unit 22 is, for example, a non-volatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, or an EEPROM. The storage unit 22 stores information determined at the time of installation of the behavior support system 1, such as the type and installation location of the detection device 11 and the projection device 12. The storage unit 22 also stores cumulatively information communicated during operation of the behavior support system 1, such as the detection results of the user's behavior and the surrounding environment received from the detection device 11, and the operating status of the detection device 11 and the projection device 12. The storage unit 22 also stores a user table, etc., in which the user's physical characteristics and the type of behavior item set by the user or administrator to perform support are stored in correspondence with the user ID that identifies the user. Among the information stored in the storage unit 22, information specific to each behavior item will be described later together with the explanation of the operation of the detection device 11, the projection device 12, and the control unit for each behavior item.

The management terminal 14 is connected to the control device 13 via wired or wireless communication. The management terminal 14 is, for example, a general-purpose PC (Personal Computer) installed in a management room or the like in the facility, or a smartphone or a dedicated terminal equipped with a CPU carried by a facility manager or the like. The management terminal 14 is used by a user to manage or control the behavior acquisition device and the projection device 12 via the control device 13. For example, the manager or the like can specify behavior items stored in the user table via the management terminal 14 regardless of the detection results of the detection device 11. The manager or the like may also set the specification of behavior items to be scheduled.

(Control by action item)
In the following, the aspects of the action support system 1 corresponding to specific action items will be described. First, the action support system 1 will be described in detail in the case where the type of action item targeted for support by the action support system 1 includes a walk. FIG. 2 is a diagram for explaining the action support system 1 according to the first embodiment. As shown in FIG. 2, the action support system 1 has a control device 13, a beacon tag 11a, a receiver 11b, a moving object detection device 11c, a projector 12a, and a lighting device 12b when the action items targeted for support include a walk. The control device 13, the receiver 11b, the moving object detection device 11c, the projector 12a, and the lighting device 12b are connected to each other so as to be able to communicate with each other, for example, via the Web or a dedicated communication network. When the action items targeted for support include a walk, the action support system 1 aims to make the walk feel comfortable, improve motivation for the walk, and assist walking.

The beacon tag 11a is worn by a user (person P1 in FIG. 2). The beacon tag 11a transmits a wireless signal such as Bluetooth (registered trademark) to the receiver 11b. The signal sent from the beacon tag 11a to the receiver 11b contains ID information that identifies the user wearing the beacon tag 11a.

Receiver 11b is attached to the ceiling or the like of a corridor C of the facility. Corridor C is an example of a location within the facility that is set in advance in the user table as a walking location when the user takes a walk. Receiver 11b detects that a user identified by the ID information received from beacon tag 11a is present within the detection range. Receiver 11b transmits a detection signal to control device 13 notifying the user of the presence within the detection range and including the ID information of the detected user. While receiver 11b detects that the user is present within the detection range, it transmits a detection signal to control device 13 at regular intervals. Receiver 11b is an example of a detection device 11 that operates together with beacon tag 11a.

The moving object detection device 11c records video while it detects a moving object, which is a user, in the corridor C, and transmits the recorded video to the control device 13. Specifically, for example, the moving object detection device 11c detects a moving object when the amount of information increases when the corridor C is photographed for a certain period of time, starts recording, and transmits the recorded video to the control device 13. Also, for example, the moving object detection device 11c may be configured with an infrared sensor and a video camera, and when it detects a heat source that radiates infrared rays, it may detect a moving object, which is a user, in the corridor C and transmit the recorded video to the control device 13. The moving object detection device 11c is an example of a detection device 11.

The memory unit 22 stores information for generating image data to be projected, such as images of scenery and walking routes, which will be described later.

When the determination conditions are met, the type determination unit 31 of the control device 13 determines that the action item for starting support is a walk. The determination conditions are, for example, the following two conditions. The first condition is that a detection signal of a user who has set a walk as the support target is received from the receiver 11b installed in the corridor C. The second condition is that recorded video is received from the moving object detection device 11c. Note that these conditions may be AND conditions or OR conditions (the same applies to other action items below).

In addition, the type determination unit 31 completes the walking support if the completion condition is met after the determination condition is met. The completion condition is, for example, that a predetermined time has elapsed without receiving a detection signal from the receiver 11b installed in the corridor C of a user who has set walking as the support target.

After the behavior items have been determined, the analysis unit 32 continuously analyzes the user's body parts and movements based on the recorded video received from the moving object detection device 11c. A specific body part is the position of the feet. Specific user movements include walking posture, walking speed, and stride length. The stride length may be calculated by measuring the foot position. The stride length may be calculated by multiplying the user's height by a value between 0.45 and 0.50.

The first output unit 33 of the control device 13 generates video data based on the measurement results of the analysis unit 32 and outputs it to the projector 12a. The video data is output data corresponding to the image to be displayed. The projector 12a displays the video data output from the first output unit 33 as an image G on a wall surface, floor surface, or the like. The projector 12a is an example of a projection device 12, and is attached to a wall or ceiling of the corridor C, or the like.

The first output unit 33 of the control device 13 generates a lighting control signal based on the measurement results of the analysis unit 32 and outputs the signal to the lighting device 12b. The lighting control signal is a signal that includes information indicating the lighting method to be operated by the lighting device 12b. Upon receiving the lighting control signal, the lighting device 12b performs the lighting method indicated by the lighting control signal. The lighting device 12b is an example of a projection device 12. The lighting device 12b is, for example, a spotlight that uses an LED (Light Emitting Diode) and is attached to the wall or ceiling of the corridor C.

The first output unit 33 outputs video data or a lighting control signal to the projector 12a or the lighting device 12b so as to display or illuminate at least one of the following four types of images. The type of display content to be displayed is determined in advance by the user or administrator.

As a first type, the first output unit 33 uses the projector 12a to display scenery images during hiking or the like. The scenery images are, for example, images of a predetermined length that record the scenery changing as the user walks. The first output unit 33 changes the scenery images stored in the memory unit 22 in response to the user's walking motion and displays them on the projector 12a. Specifically, when the user walks, the scenery images are played back frame by frame for an amount corresponding to the stride length so that the user can experience moving forward by the stride length. This makes the user feel comfortable while walking, and increases motivation for walking.

As the second type, the first output unit 33 displays a walking route by the projector 12a. FIG. 3 is a diagram for explaining the action support system 1 according to the first embodiment. FIG. 4 is a diagram for explaining the action support system 1 according to the first embodiment. FIG. 3 and FIG. 4 show a case where the action item is a walk. FIG. 4 is a diagram for explaining a case where the action item is a walk in the action support system 1 according to the first embodiment. As shown in FIG. 3, the first output unit 33 displays a walking route T on the front side of the person P1 based on the user's posture and foot position. The walking route is a route on the corridor C, and is set in advance according to the installation direction of the projector 12a. Also, as shown in FIG. 4, the first output unit 33 deletes the walking route that the user has already finished walking from the video data so as to output only the walking route T on the front side of the person P1 based on the user's posture and foot position. This makes it possible to assist the user's walking.

As the third type, the first output unit 33 displays a walking mark by the lighting device 12b. The walking mark indicates the position where the next stepping foot should be placed. In FIG. 2, the walking mark is shown as walking mark L1. The first output unit 33 displays the walking mark according to the foot position, walking speed, stride length, etc. Specifically, when the left foot is forward, the walking mark of the right foot is displayed before the right foot moves forward. Similarly, when the right foot is forward, the walking mark of the left foot is displayed before the left foot moves forward. The timing for displaying the walking mark is, for example, immediately after the walking mark of one foot touches the ground with the other foot. The display position of the walking mark is, for example, a position at a distance of the stride length of the target foot on the walking path described above. This makes it possible to assist the user in walking. In addition, the walking marks of the right foot and the left foot may be moved seamlessly, taking into account the walking speed. As an example, immediately after the left foot lands, the circular pattern or footprint pattern may be moved at walking speed on each of the left and right walking paths while maintaining the shape of the pattern from the tip of the right foot to the stride. In this way, the user can be assisted in walking at an appropriate walking speed. In addition, the walking mark may be a specific shape, such as a specific symbol or footprint, by placing a light-shielding sheet with a specific graphic pattern on the emission side of the lighting device 12b.

As a fourth type, the first output unit 33 displays a gaze mark using the lighting device 12b. The gaze mark is a mark that guides the user's gaze. In FIG. 2, the gaze mark is shown as gaze mark L2. The first output unit 33 displays the gaze mark away from the feet based on the user's posture and foot position. The gaze mark may have a shape such as a circle, and may be displayed brightly to attract the user's attention. In addition, the first output unit 33 causes the display position of the gaze mark to follow the user's walking. This makes it possible to guide the user's gaze away from the feet, and encourage improvement in walking posture.

Note that a display may be used instead of the projector 12a. The walking route may be displayed using the lighting device 12b. When the lighting device 12b is used to display the walking route, for example, the lighting devices 12b may be dotted in the corridor C and turned on only at positions corresponding to the walking route ahead. The walking marks and gaze marks may be displayed using the projector 12a. In this case, the walking marks may be in the shape of footprints, for example.

In addition, while FIG. 2 illustrates a corridor C with a ceiling, it may be an open space without a ceiling or part of a wall. The receiver 11b, the motion detection device 11c, the projector 12a, and the lighting device 12b may be installed at any position by the manager, etc., as long as they are capable of performing their functions.

Figure 5 is a flowchart showing the operation of the control device 13 according to the first embodiment. The operation of the control device 13 will be described using Figure 5. First, the type determination unit 31 determines whether or not the determination condition is satisfied (S1). If the determination condition is not satisfied (S1: NO), the control device 13 waits until the determination condition is satisfied. If the determination condition is satisfied (S1: YES), the type determination unit 31 determines "walk" as the action item for starting support (S2).

Next, the analysis unit 32 analyzes the recorded video received from the motion detection device 11c and measures the user's body parts and movements (S3). Next, the first output unit 33 generates video data or a lighting control signal based on the measurement results of the analysis unit 32 (S4) and causes the projection device 12 to display the image or provide illumination (S5).

Then, the type determination unit 31 determines whether the completion condition is met (S6). If the completion condition is not met (S6: NO), the control device 13 continues the control of S3 to S5 until the completion condition is met. If the completion condition is met (S6: YES), the control device 13 completes the control when a walk is being performed as the action item.

In this way, the action support system 1 can make the walk feel comfortable, increase motivation for the walk, and provide walking assistance based on the results detected by the detection device 11.

In particular, because the content of the video and the lighting method change in accordance with the user's walk, the user can experience the sensation that the content of the video and the lighting method are linked to their own movements, further encouraging the user to be more spontaneous.

The action support system 1 will be described in detail for a case where the types of action items supported by the action support system 1 include stair climbing. The action support system 1 has a control device 13, a beacon tag 11a, a receiver 11b, a motion detection device 11c, a projector 12a, and a lighting device 12b. When the types of action items supported by the action support system 1 include stair climbing, the action support system 1 aims to improve motivation for climbing and descending stairs and to provide assistance with climbing and descending stairs.

Each device of the action support system 1 is the same as the device of the action support system 1 when supporting stair climbing and descending, so a description is omitted. However, the receiver 11b, the motion detection device 11c, the projector 12a, and the lighting device 12b are attached, for example, to a wall or ceiling near the stairs in the facility. The stairs are an example of a place that is set in advance by the user as a place where the stairs are to be ascended or descended. Note that step climbing and descending may be regarded as an activity equivalent to stair climbing and descending, and the place where the step climbing and descending is performed may be set as the place where the stair climbing and descending is to be performed.

When the determination conditions are met, the type determination unit 31 of the control device 13 determines that the action item for which support is to be started is climbing stairs. The determination conditions are, for example, the following two conditions. The first condition is that a detection signal of a user who has set climbing stairs as a support target is received from a receiver 11b installed near the stairs. The second condition is that recorded video is received from the moving object detection device 11c.

Furthermore, the type determination unit 31 completes the assistance for ascending and descending stairs if a completion condition is met after the determination condition is met. The completion condition is, for example, that a predetermined time has elapsed without receiving a detection signal from a receiver 11b installed near the stairs of a user who has set ascending and descending stairs as a support target.

After the behavior items have been determined, the analysis unit 32 continuously analyzes the video received from the moving object detection device 11c, and continuously measures the user's body parts and movements. Specific body parts are the feet. Specific user movements measured include the ascending and descending posture and ascending and descending speed.

The first output unit 33 generates video data based on the measurement results of the analysis unit 32 and outputs it to the projector 12a. The first output unit 33 of the control device 13 also generates a lighting control signal based on the measurement results of the analysis unit 32 and outputs it to the lighting device 12b. The first output unit 33 outputs the video data or lighting control signal to the projector 12a or the lighting device 12b so as to display or illuminate at least one of the following two types of images.

As a first type, the first output unit 33 causes the projector 12a to display, for example, scenery images taken while climbing a mountain. The scenery images are, for example, moving images of a predetermined length, which record the gradual changes in the scenery. This can increase motivation to climb stairs.

As the second type, the first output unit 33 provides lighting to brighten the user's feet while following the user going up and down the stairs. This can assist the user in going up and down the stairs.

The operation of the control device 13 is the same as the processing when walking is the support target, so a description will be omitted. As described above, the action support system 1 can make the user feel comfortable going up and down stairs based on the results detected by the detection device 11, thereby increasing motivation for going up and down stairs and providing walking assistance.

In particular, the content of the images and the lighting method change in accordance with the user's movements as they ascend and descend the stairs, allowing the user to experience a sensation linked to their own movements and encouraging them to be more spontaneous.

The action support system 1 will be described in detail for a case where gymnastics is included in the types of action items supported by the action support system 1. The action support system 1 has a control device 13, a beacon tag 11a, a receiver 11b, a motion detection device 11c, a projector 12a, and a lighting device 12b. When gymnastics is included in the types of action items supported by the action support system 1, the purpose of the action support system 1 is to improve motivation for gymnastics and to assist with the exercises.

Each device of the action support system 1 is the same as the device of the action support system 1 when supporting a walk, so a description is omitted. However, the receiver 11b, the moving object detection device 11c, the projector 12a, and the lighting device 12b are attached to, for example, a wall or ceiling of a hall in the facility. The hall is an example of a place that is set in advance by the user as a place to perform exercises.

When the determination conditions are met, the type determination unit 31 of the control device 13 determines that the action item for which support is to be started is gymnastics. The determination conditions are, for example, the following two conditions. The first condition is that a detection signal of a user who has set gymnastics as the support target is received from a receiver 11b installed in the hall. The second condition is that recorded video is received from a moving object detection device 11c installed in the hall.

Furthermore, the type determination unit 31 completes the exercise support if the completion condition is met after the determination condition is met. The completion condition is, for example, that a predetermined time has elapsed without receiving a detection signal from the receiver 11b installed in the hall of a user who has set exercise as the support target.

After the behavioral items have been determined, the analysis unit 32 continuously analyzes the video received from the moving object detection device 11c and continuously measures the user's body parts and movements.

The first output unit 33 generates video data based on the measurement results of the analysis unit 32 and outputs it to the projector 12a. The first output unit 33 of the control device 13 also generates a lighting control signal based on the measurement results of the analysis unit 32 and outputs it to the lighting device 12b. The first output unit 33 outputs the video data or lighting control signal to the projector 12a or the lighting device 12b so as to display or illuminate at least one of the following two types of images.

As a first type, the first output unit 33 displays, for example, an image of a person performing exercises on the projector 12a. This image is, for example, a video of a predetermined length in which a person performs a series of movements such as radio exercises. This can reduce resistance to performing exercises and improve motivation for doing exercises.

As a second type, the first output unit 33 changes the color or brightness of the lighting to match the tempo of the exercise. This can assist the user in performing the exercise.

In addition, if the analysis result of the analysis unit 32 indicates that the user's movement does not correspond to exercises, the first output unit 33 determines that there is no indication of exercises and stops displaying or lighting the image.

The operation of the control device 13 is the same as the processing when the support target is walking, so a description thereof will be omitted. As described above, the action support system 1 can reduce the resistance to performing exercises, increase motivation for exercises, and provide assistance with exercises based on the results detected by the detection device 11.

The action support system 1 will be described in detail in the case where eating is included in the types of action items supported by the action support system 1. FIG. 6 is a diagram for explaining the action support system 1 according to the first embodiment. As shown in FIG. 6, the action support system 1 has a control device 13, a beacon tag 11a, a receiver 11b, a moving object detection device 11c, and a lighting device 12b. When eating is included in the types of action items supported by the action support system 1, the purpose of the action support system 1 is to improve motivation for eating and to provide assistance with eating.

The devices of the action support system 1 are the same as those of the action support system 1 when the action items to be supported include walking, and therefore will not be described. However, the receiver 11b, the motion detection device 11c, and the lighting device 12b are attached, for example, to the wall or ceiling of a room R1 in the facility. The room R1 is an example of a place that is set up in advance as a place to eat, such as a dining room.

When the determination conditions are met, the type determination unit 31 of the control device 13 determines that the action item for which support is to be started is eating. The determination conditions are, for example, the following two conditions. The first condition is that a detection signal of a user who has set eating as the support target is received from the receiver 11b installed in room R1. The second condition is that recorded video is received from the moving object detection device 11c installed in room R1.

Furthermore, the type determination unit 31 completes the meal support if the completion condition is met after the determination condition is met. The completion condition is, for example, that a predetermined time has elapsed without receiving a detection signal from the receiver 11b installed in room R1 of a user who has set meals as the support target.

After the behavioral items have been determined, the analysis unit 32 continuously analyzes the recorded video received from the motion detection device 11c, and analyzes the number of times the user chews, the pace at which the meal is eaten, the menu served in front of the user, etc.

The first output unit 33 of the control device 13 generates a lighting control signal based on the analysis result of the analysis unit 32 and outputs it to the lighting device 12b. The first output unit 33 outputs the lighting control signal to the lighting device 12b to perform at least one of the following three types of lighting. The control device 13 may analyze the food leftover situation and accumulate data linked to the user to grasp personal preferences and health conditions.

In the first type, the first output unit 33 illuminates the table with warm light. This makes the dining environment more comfortable and increases motivation to eat.

In the second type, the first output unit 33 shines a spotlight on a specific dish. In FIG. 6, for example, a spotlight L3 is shining on a specific dish from the meal F that is served in front of person P2. The specific dish is, for example, vegetables. By illuminating the vegetables first after starting assistance, it is possible to encourage eating vegetables at the beginning of the meal and suppress the rise in blood sugar levels. The specific dish may also be a dish that is left over in large portions.

As a third type, the first output unit 33 changes the color or brightness of the lighting in accordance with the eating pace. Specifically, for example, if the eating pace is too fast, the first output unit 33 gently fluctuates the illuminance and color temperature of the lighting. This makes it possible to prompt the user to slow down the eating pace.

The operation of the control device 13 is the same as the processing when the support target is a walk, so a description is omitted. As described above, the action support system 1 can improve motivation for eating and provide meal assistance based on the results detected by the detection device 11.

Details of the action support system 1 will be described for a case where conversation is included in the types of action items supported by the action support system 1. FIG. 7 is a diagram for explaining the action support system 1 according to the first embodiment. As shown in FIG. 7, the action support system 1 has a control device 13, a beacon tag 11a, a receiver 11b, a moving object detection device 11c, a projector 12a, and an audio sensor 11d. When conversation is included in the types of action items supported by the action support system 1, the purpose of the action support system 1 is to improve motivation for conversation.

The control device 13, beacon tag 11a, receiver 11b, moving object detection device 11c, and projector 12a are the same as the devices in the action support system 1 when supporting a walk, and therefore a description thereof will be omitted. However, the receiver 11b, moving object detection device 11c, and lighting device 12b are attached, for example, to a wall or ceiling of room R2 in the facility. Room R2 is an example of a place that is set in advance as a place where a conversation will take place. The sound sensor 11d is, for example, a microphone, and is attached to a table or the like in room R2.

When the determination conditions are met, the type determination unit 31 of the control device 13 determines that the action item for which support is to be started is a conversation. The determination conditions are, for example, the following two conditions. The first condition is that a detection signal of a user who has set a conversation as the support target is received from the receiver 11b installed in room R2. The second condition is that recorded video is received from the motion detection device 11c installed in room R2.

Furthermore, the type determination unit 31 completes the conversation support if the completion condition is met after the determination condition is met. The completion condition is, for example, that a predetermined time has elapsed without receiving a detection signal from the receiver 11b installed in room R2 of a user who has set the conversation as the support target.

After the action items have been determined, the analysis unit 32 continuously analyzes the video received from the motion detection device 11c and continuously measures the user's movements. Specifically, the user's movements are measured by measuring the user's facial expressions and the content of the conversation. The analysis unit 32 also analyzes the sound from the audio sensor to extract keywords and the like contained in the conversation. The analysis unit 32 also extracts from the video stored in the memory unit 22 those matters associated with the extracted keywords. In other words, the analysis unit 32 extracts video that expands on the content of the user's conversation.

The first output unit 33 of the control device 13 generates the image extracted by the analysis unit 32 as image data based on the measurement results of the analysis unit 32, and outputs the image data to the projector 12a. In FIG. 7, image G2 is displayed to person P3, and image G3 is displayed to person P4.

The operation of the control device 13 is the same as the processing when the support target is a walk, so a description is omitted. As described above, the action support system 1 can reduce the resistance to conversation, increase motivation for conversation, and provide conversation assistance based on the results detected by the detection device 11.

The action support system 1 will be described in detail in the case where the types of action items supported by the action support system 1 include hobbies. FIG. 8 is a diagram for explaining the action support system 1 according to the first embodiment. As shown in FIG. 8, the action support system 1 has a control device 13, a beacon tag 11a, a receiver 11b, a moving object detection device 11c, a projector 12a, and a lighting device 12b. When the action items supported by the action support system 1 include hobbies, the purpose of the action support system 1 is to improve motivation for the hobby and to relax the user while performing the hobby.

The devices of the action support system 1 are the same as those in the case where the action item is walking, and so a description thereof will be omitted. However, the receiver 11b, the motion detection device 11c, the projector 12a, and the lighting device 12b are attached, for example, to the wall or ceiling of room R3 in the facility. Room R3 is an example of a place, such as a living room, that is set in advance by the user as a place for carrying out hobbies.

The type determination unit 31 of the control device 13 determines that the action item is a hobby if a determination condition is met. The determination condition is, for example, to analyze the video received from the motion detection device 11c installed in room R3 and determine that the video received from the motion detection device 11c shows the user engaged in an activity designated as a hobby. Hobbies include, for example, handicrafts, reading, mahjong, and calligraphy, and are stored in the user table.

Furthermore, the type determination unit 31 completes the hobby support if a completion condition is met after the determination condition is met. The completion condition is, for example, to analyze the video received from the motion detection device 11c installed in room R3 and determine that the user has not engaged in the activity designated as a hobby for a predetermined period of time in the video received from the motion detection device 11c.

After the action items have been determined, the analysis unit 32 continuously analyzes the video received from the moving object detection device 11c and continuously measures the user's actions. The analysis unit 32 measures the user's activity time, etc.

The first output unit 33 generates video data based on the measurement results of the analysis unit 32 and outputs it to the projector 12a. The first output unit 33 also generates a lighting control signal based on the measurement results of the analysis unit 32 and outputs it to the lighting device 12b. The first output unit 33 outputs the video data or lighting control signal to the projector 12a or the lighting device 12b so as to display or illuminate at least one of the following three types of video:

In the first type, the first output unit 33 displays an image related to the subject designated as the hobby. For example, if needlework is designated as the hobby, an image of how to knit or a finished product is displayed. This can improve motivation for the hobby. In FIG. 8, G4 is displayed for person P5.

As a second type, when the user's activity time exceeds a predetermined time, the first output unit 33 displays a landscape image or an image that is not related to the hobby, etc., to encourage the user to take a break. This can prevent the user from concentrating too much on the hobby and becoming tired.

As a third type, the first output unit 33 provides lighting to brightly illuminate the user's hands. This allows the user to feel comfortable while working on handicrafts or other handiwork, thereby improving motivation for the hobby.

The operation of the control device 13 is the same as the processing when the support target is walking, so a description is omitted. As described above, the action support system 1 can improve motivation for hobbies and provide support for hobbies based on the results detected by the detection device 11.

The action support system 1 will be described in detail for a case where bathing is included in the types of action items supported by the action support system 1. The action support system 1 has a control device 13, a beacon tag 11a, a receiver 11b, and a projector 12a. When bathing is included in the action items supported by the action support system 1, the purpose of the action support system 1 is to increase motivation for bathing and to provide assistance with bathing.

Each device of the activity support system 1 is the same as the device of the activity support system 1 when supporting a walk, so a description is omitted. However, the receiver 11b is attached to the changing room of the bathroom, etc., and the projector 12a is attached to a wall or ceiling of the hallway near the bathroom, and to a wall or ceiling inside the bathroom.

When the determination condition is met, the type determination unit 31 of the control device 13 determines that the action item for which support is to be started is bathing. The determination condition is, for example, that it is a time period during which a predetermined bathing schedule is reached.

Furthermore, the type determination unit 31 completes the bathing assistance if the completion condition is met after the determination condition is met. The completion condition is, for example, that one of the following two conditions is met. The first condition is that a pre-set time period for scheduled bathing has passed. The second condition is that the completion of the user's bathing is communicated to the behavior type determination. The completion of the user's input may be input, for example, by a terminal device such as a smartphone that is capable of communicating with the control device 13.

After the action item has been determined, the analysis unit 32 receives a detection signal from the receiver 11b set in the changing room of the bathroom, indicating that the user has set bathing as a support target, and determines that the user is in the changing room of the bathroom or in the bathroom.

The first output unit 33 generates video data based on the processing results of the analysis unit 32 and outputs it to the projector 12a. The first output unit 33 outputs the video data to the projector 12a so as to display at least one of the following two types of video:

As a first type, the first output unit 33 causes the projector 12a installed in the hallway near the bathroom to display an arrow or the like indicating the route to the bathroom. This allows the user to be smoothly guided to the bathroom.

As a second type, when the user is in the changing room of the bathroom, an image of a forest or the ocean, for example, is displayed on the ceiling or walls of the bathroom. This gives the user a sense of openness, making bathing feel comfortable and increasing motivation to bathe.

The operation of the control device 13 is the same as the processing when the support target is a walk, so a description is omitted. As described above, the action support system 1 can increase motivation for bathing and provide assistance with bathing based on the results detected by the detection device 11.

The action support system 1 will be described in detail for a case where waking up is included in the types of action items that are the target of support by the action support system 1. The action support system 1 has a control device 13, a projector 12a, a lighting device 12b, and a sleep sensor (not shown). When waking up is included in the action items to be supported, the action support system 1 aims to assist with waking up.

The control device 13, projector 12a, and lighting device 12b are the same as the devices in the action support system 1 when supporting a walk, and therefore a description thereof will be omitted. However, the projector 12a and lighting device 12b are attached, for example, to a wall or ceiling of a bedroom in the facility. The sleep sensor is, for example, a mat-type sensor that is placed on the bed or futon on which the user sleeps. The sleep sensor outputs an electrical signal according to the pressure applied to the mat.

When the determination condition is met, the type determination unit 31 of the control device 13 determines that the action item for which support is to be started is waking up. The determination condition is, for example, that the time period during which the user is scheduled to wake up is set in advance.

In addition, the type determination unit 31 completes the wake-up support if a completion condition is met after the determination condition is met. The completion condition is, for example, that a preset scheduled wake-up time period has passed.

After the action items have been determined, the analysis unit 32 continuously analyzes the results received from the sleep sensor and analyzes the depth of the user's sleep over time.

The first output unit 33 generates video data or a lighting control signal and outputs it to the projector 12a or the lighting device 12b so as to display or illuminate at least one of the following two types of video:

In the first type, when the user's sleep becomes light, the first output unit 33 causes the projector 12a installed in the bedroom to display an image that mimics people around the user waking up.

In the second type, when the user's sleep becomes lighter, the first output unit 33 adjusts the brightness and color of the lighting throughout the bedroom to, for example, an illuminance of 500 Lux or more (on the bed or futon) and a color temperature of more than 4000K.

It is advisable to install the lighting device 12b next to a window so that it irradiates light in the direction of the bed. This allows the user to feel as if sunlight is shining into the bedroom, allowing the user to wake up comfortably even on a cloudy or rainy day. It is also possible to use a spotlight for the lighting device 12b so that light close to parallel light is irradiated onto the bed.

The operation of the control device 13 is the same as the processing when the support target is a walk, so a description is omitted. As described above, the action support system 1 can assist in waking up based on the results detected by the detection device 11.

The action support system 1 will be described in detail for a case where going to sleep is included in the types of action items that are the target of support by the action support system 1. The action support system 1 has a control device 13, a projector 12a, a lighting device 12b, and a sleep sensor. When going to sleep is included in the action items to be supported, the action support system 1 aims to assist with going to sleep.

The control device 13, projector 12a, and sleep sensor devices themselves, as well as their installation locations, are similar to those of the behavior support system 1 when assisting with waking up, and therefore will not be described here.

When the determination condition is met, the type determination unit 31 of the control device 13 determines that the action item for which support is to be started is going to bed. The determination condition is, for example, that it is a time period during which the user is scheduled to go to bed that has been set in advance.

Furthermore, the type determination unit 31 completes the sleep support if a completion condition is met after the determination condition is met. The completion condition is, for example, that a pre-set time period for the planned sleep has passed.

After the action items have been determined, the analysis unit 32 continuously analyzes the results received from the sleep sensor to analyze the timing at which the user lay down in bed and the depth of sleep.

The first output unit 33 generates video data or a lighting control signal and outputs it to the projector 12a or the lighting device 12b so as to display or illuminate at least one of the following two types of video:

In the first type, the first output unit 33 causes the projector 12a installed in the bedroom to display an image reminiscent of night, such as a moon, on the wall of the bedroom when the user lies down in bed. Furthermore, the first output unit 33 ends the display of the image when it is determined from the analysis results of the analysis unit 32 that the user has fallen asleep.

As a second type, the first output unit 33 causes the lighting device 12b installed in the bedroom to provide illumination of about moonlight of 10 Lux or less when the user lies down on the bed. In addition, the first output unit 33 ends the display of the image when it is determined from the analysis result of the analysis unit 32 that the user has fallen asleep.

The operation of the control device 13 is the same as the processing when the support target is a walk, so a description is omitted. As described above, the action support system 1 can provide assistance with going to sleep based on the results detected by the detection device 11.

As described above, according to the first embodiment, an image related to an action item is displayed or illuminated based on the result of detection by the detection device 11. This makes it possible to indirectly encourage the user to perform a specific activity without directly instructing the user to do so. This makes it possible to encourage the user to be more voluntary in their activities.

Embodiment 2.
Fig. 9 is a functional block diagram showing a behavior support system 1A according to embodiment 2. As shown in Fig. 9, the control device 13 of embodiment 2 does not have a first output unit 33 and a projection device 12, but differs from embodiment 1 in that it has an evaluation unit 41, an addition unit 42, and a communication unit 43. In embodiment 2, the same parts as those in embodiment 1 are given the same reference numerals and their description is omitted, and the description will focus on the differences from embodiment 1.

Unlike in embodiment 1, the action support system 1A in embodiment 2 does not display images or provide illumination. The action support system 1A in embodiment 2 awards social contribution points to a user who has performed an action item whose main purpose is physical exercise, such as taking a walk, climbing stairs, or calisthenics. The control device 13 is communicatively connected to an external system that performs activities that lead to the resolution of social issues, such as reforestation, building schools in developing countries, or vaccination, in exchange for the social contribution points held by the user. In other words, the user can contribute to social contribution activities using the social contribution points accumulated through their own activities.

The memory unit 22 of the control device 13 stores an ID that identifies the user and a points table that stores the social contribution points held by the user.

The evaluation unit 41 of the control device 13 evaluates the exercise posture and the amount of exercise after the action item is completed, when the action item is a walk, climbing up and down stairs, or exercise. For example, in the case of a walk, the exercise posture may be evaluated comprehensively from the measured walking posture, walking speed, and stride length. The amount of exercise may be, for example, the walking distance calculated by multiplying the measurement time of the analysis unit 32, that is, the time from when the determination condition is satisfied to when the completion condition is satisfied, by the average walking speed. Various evaluation criteria are adopted. For example, based on the history of the detection results of the user's movements, a high numerical evaluation may be given if improvement is observed, and a low numerical evaluation may be given if no improvement is observed. Also, a graded evaluation such as high, medium, or low may be given depending on the degree to which a predetermined standard is met based on the measurement results of the walking posture, walking speed, stride length, etc. of a person of similar age, sex, physique, etc.

The addition unit 42 adds different values of social contribution points to the points table depending on the evaluation result. For example, if the evaluation of the exercise posture and the amount of exercise is high, a higher value of social contribution points is added to the points table.

Although the above description mainly deals with the case where the action item is walking, the exercise posture and amount of exercise may also be calculated and evaluated for going up and down stairs and exercise. For example, if the action item is going up and down stairs, the exercise posture may be calculated from the ascent and descent posture and the ascent and descent speed, and the amount of exercise may be calculated using the number of ascent and descent steps, etc. Furthermore, if the action item is exercise, only the amount of exercise may be calculated from the time the exercise was performed and the displayed exercise menu.

The communication unit 43 of the control device 13 subtracts the points held by the user stored in the points table, and transmits information to the external system S requesting a points exchange. When the external system S executes the points exchange, the user is able to realize social contribution activities.

Figure 10 is a flowchart showing the operation of the control device 13 according to the second embodiment. The operation of the control device 13 will be described using Figure 10. The processes from S1 to S3 are similar to those described in the first embodiment, and therefore will not be described. When the user's movements and the like are analyzed and measured (S3), the type determination unit 31 determines whether or not the completion condition is met (S11). If the completion condition is not met (S11: NO), the analysis unit 32 continues to analyze and measure the user's movements and the like until the completion condition is met. If the completion condition is met (S11: YES), the evaluation unit 41 calculates the amount of exercise and the exercise posture of the user and performs an evaluation (S12). Then, based on the evaluation result performed by the evaluation unit 41, social contribution points are added to the points table (S13).

According to the second embodiment, social contribution points are awarded based on the results detected by the detection device 11. This makes it possible to indirectly encourage the user to perform a specific activity without directly instructing the user to do so. This makes it possible to encourage the user to engage in spontaneous activities.

Embodiment 3.
Fig. 11 is a functional block diagram showing a behavior support system 1B according to embodiment 3. As shown in Fig. 11, in embodiment 3, the control device 13 has, in addition to the configuration of embodiment 1, the evaluation unit 41, the addition unit 42, and the communication unit 43 described in embodiment 2, as well as a second output unit 51 not included in embodiments 1 and 2. In embodiment 3, the same parts as those in embodiments 1 and 2 are denoted by the same reference numerals and description thereof is omitted, and the differences from embodiments 1 and 2 will be mainly described.

The action support system 1B of the third embodiment displays or illuminates images as described in the first embodiment. In addition, as described in the second embodiment, social contribution points are awarded to a user who has performed an action item whose main purpose is physical exercise, such as walking, climbing stairs, or calisthenics. Furthermore, the action support system 1B of the third embodiment displays information related to the awarded social contribution points by means of images. The following will explain the case where the action item is walking, for example.

As described above, the type determination unit 31, the analysis unit 32, and the first output unit 33 of the control device 13 of embodiment 3 are similar to the type determination unit 31, the analysis unit 32, and the first output unit 33 of embodiment 1. Similarly, the evaluation unit 41 and the addition unit 42 of the control device 13 of embodiment 3 are similar to the evaluation unit 41 and the addition unit 42 of embodiment 2.

When the completion condition is met, the second output unit 51 of the control device 13 generates evaluation video data and outputs it to the projection device 12 to display the evaluation video. The evaluation video data is output data that determines the specific content of the evaluation video. The evaluation video is a video whose content includes the evaluation result of the evaluation unit 41.

12 is a diagram for explaining the second output unit 51 according to the third embodiment. In FIG. 12, the person P6 has a high evaluation result for his/her exercise posture, and the person P7 has a low evaluation result for his/her exercise posture. FIG. 13 is a diagram showing an evaluation image G5 displayed by the projector 12a according to the third embodiment. FIG. 13 shows an evaluation image displayed on a wall surface or the like by the projector 12a after the person P6 has completed a walk. As shown by the dashed line M1 in FIG. 13, the second output unit 51 displays the social contribution points granted by the current activity based on the evaluation result of the evaluation unit 41. Also, as shown by the dashed line M2, the second output unit 51 displays the cumulative social contribution points by referring to the social contribution points owned by the user stored in the point table. Also, as shown by the dashed line M3, the second output unit 51 displays the social contribution points required for the purpose previously set by the user by communicating with the external system S via the communication unit 43. As indicated by dashed line M4, comments according to the evaluation of exercise posture and amount of exercise are referenced from a list of comments previously stored in storage unit 22, and comments on areas for improvement, etc. are displayed. As indicated by dashed line Ic1, second output unit 51 references symbol data according to the evaluation of exercise posture or amount of exercise from a list of symbol data previously stored in storage, and displays a symbol indicating the evaluation. Person P6 received a high evaluation for his/her exercise posture, so the symbol "sunny" is displayed. Symbols such as "sunny," "cloudy," and "rainy" are used in descending order of the rank of the evaluation result.

Figure 14 is a diagram showing an evaluation image G6 displayed by the projector 12a according to the third embodiment. Figure 14 shows an evaluation image displayed on a wall surface or the like by the projector 12a after person P7 has completed his walk. The evaluation image shown in Figure 14 also shows the social contribution points acquired through the current activity, as shown by the dashed line M5. Also, as shown by the dashed line M6, the cumulative social contribution points are displayed. Also, as shown by the dashed line M7, the social contribution points required for the purpose previously set by the user are displayed. Also, as shown by the dashed line M8, comments on areas for improvement are displayed. Person P7's evaluation result for exercise posture was low, so the social contribution points acquired through the current activity are lower than those of person P6, and as shown by the dashed line Ic2, the evaluation result is medium, so the "cloudy" symbol is displayed.

In addition, the following evaluation images may be displayed in addition or instead. FIG. 15 is a diagram showing evaluation image G7 displayed by projector 12a according to embodiment 3. FIG. 15 shows an image of forest trees increasing and growing when the user selects, for example, "afforestation and nature conservation" as the use of social contribution points. Furthermore, evaluation image G7 displays the amount of trees that can be planted, which is equivalent to the social contribution points awarded for the current activity, as shown by the area surrounded by dashed line E1. This allows the user to visually recognize how much social contribution can be made with the social contribution points awarded for the current activity.

Figure 16 shows an evaluation image G8 displayed by projector 12a according to embodiment 3. As shown in Figure 16, if the user selects, for example, "humanitarian aid" as the use of the social contribution points, an image is displayed that shows children around the world smiling. Furthermore, as shown by the area enclosed by dashed line E2, evaluation image G8 displays a part of the school that corresponds to the social contribution points awarded for the current activity. This allows the user to visually recognize how much social contribution can be made with the social contribution points awarded for the current activity.

In addition, various types of images are used depending on the purpose selected for the social contribution points. For example, if "ocean conservation" is selected as the purpose for the social contribution points, an image of the ocean becoming cleaner is displayed, and if "animal protection" is selected as the purpose for the social contribution points, an image of animals increasing in number and becoming healthier is projected.

Figure 17 is a flowchart showing the operation of the control device 13 according to the third embodiment. The operation of the control device 13 will be described using Figure 17. The processes from S1 to S6 are similar to those described in the first embodiment, and therefore will not be described. If the completion condition is met (S6: YES), the evaluation unit 41 performs an evaluation based on the amount of exercise and exercise posture of the user (S21). The addition unit 42 adds social contribution points to the points table based on the evaluation result of the evaluation unit 41 (S22). Next, the second output unit 51 generates evaluation video data (S23) and causes the video to be displayed (S24). The control device 13 then completes the operation when a walk is being performed as the action item.

According to the third embodiment, social contribution points are awarded based on the results detected by the detection device 11, and the degree of contribution is displayed in a video. This makes it possible to indirectly encourage the user to perform a specific activity without directly instructing the user to do so. This makes it possible to encourage the user to take part in spontaneous activities.

In addition, by displaying images, information can be conveyed intuitively to elderly users of facilities for the elderly.

The above is a description of the action support systems 1, 1A, and 1B of the present disclosure, but various modifications can be made within the scope of the spirit of the disclosure. For example, the color tone of the video data output by the first output unit 33 and the evaluation video data output by the second output unit 51 described in embodiments 1 and 3 may be corrected. For example, the brightness of blue in the displayed image may be made brighter and the brightness of yellow may be made darker. This allows even a user who has difficulty seeing blue due to aging to feel the realism of the image.

In addition, in the first and third embodiments, when the user is performing exercises, the first output unit 33 may correct the video data so as to brighten and emphasize the ends or joints of the hands, feet, etc. of the person included in the video. Furthermore, when the user is performing an activity of an action item whose main purpose is physical exercise, the first output unit 33 may brighten the ends or joints of the hands, feet, etc. of the user's body using the lighting device 12b, or may emphasize them by displaying an image. This makes it easier to avoid collisions between the user and people or objects around the user.

In addition, in the first and third embodiments, the first output unit 33 may provide illumination in random positions or display an image in which shapes move randomly so as to move the user's line of sight. The image may display a shape such as a circle, for example, on the floor or wall. Generally, a user whose field of vision has narrowed due to aging may have difficulty walking, such as bumping into or tripping over objects placed on the wall or floor. By displaying random types using images or illumination, the user's line of sight can be guided and the field of vision can be improved. This leads to the maintenance and improvement of the user's walking function.

In addition, in the first and third embodiments, when carrying out an activity for an action item such as a conversation or a hobby, an image related to the user may be displayed. This can prevent the user from forgetting things. The data for outputting the image may be stored in the user table of the storage unit 22 in association with the user ID, for example, by receiving a storage medium such as a photograph or a hard disk from the user or a family member when moving into a facility.

In addition, in the first and third embodiments, when performing an activity for the action item of going to bed, a digest of the day's activities may be displayed. This can prevent the user from forgetting things or strengthen short-term memory. The data for outputting the digest may be footage captured when the user performs an activity defined as an action item, or when the user performs an activity for an action item such as conversation or a hobby, the footage displayed at that time may be displayed.

In addition, in the first and third embodiments, when a person approaches the user, the direction of the person may be illuminated. Furthermore, when the distance between the user and an object placed on a wall, floor, or the like becomes smaller than a predetermined distance, the object placed on the wall, floor, or the like may be illuminated. This makes it possible to alert the user to avoid colliding with people or objects. In particular, when the light is illuminated in the direction of a person approaching the user, it is possible that the person is trying to talk to the user, and therefore the user can be notified that he or she may be called out to.

In addition, in the first and third embodiments, when a person approaches the user and light is emitted by the lighting device 12b, the emitted light may be a color preferred by each user.

The control of the projection device 12 shown in the modified examples described so far may be performed when the user is performing an activity defined as an action item, or may be performed independently when the user is not performing an activity defined as an action item.

In addition, in embodiment 3, when displaying the evaluation video, an external system S may be accessed to display a video related to the social contribution activity that is closest to the cumulative social contribution points.

In the first to third embodiments, the control device 13 is described as a server device, but the control device 13 may be realized as a function of the management terminal 14, for example. It may also be realized as a function of the projection device 12 or the detection device 11.

The action items described in the first embodiment are merely an example, and do not need to be limited to nine items. For example, action items may be further categorized, such as conversations with relatives and conversations with friends, and hobbies as handicrafts, reading, mahjong, and calligraphy. Furthermore, an action item for exercise may be provided, and action items belonging to exercise may be categorized as walking, exercise, dancing, climbing stairs, etc.

In addition, instead of the social contribution points described in the second and third embodiments, points that can be used for purposes other than social contribution may be used. In this case, too, by linking the user's activities with the awarding of points, the motivation of the user's activities can be promoted.

In addition, in the third embodiment, the first output unit 33 may display the walking mark or the gaze mark in blue or green based on the evaluation by the evaluation unit 41. If the evaluation of the walking posture is low, the first output unit 33 may display the walking mark or the gaze mark in yellow or red. This can enhance the effect of improving the user's walking posture.

The projection device 12 and the detection device 11 described in the first embodiment are merely examples. For example, if the location where the support image or the evaluation image is displayed is other than the space such as the floor, wall, or ceiling, the projection device 12 may be a display instead of the projector 12a. Also, a VR device may be used as the projection device 12. This can give the image a sense of realism. Also, a LIDAR (Laser Imaging Detection and Ranging) may be used as the detection device 11. This can, for example, measure the position of the user's feet with higher accuracy. Also, in each embodiment, the user can be identified by the beacon tag 11a. However, other indoor positioning technologies such as Wi-Fi may be used. Also, if the user can be identified by analyzing the user's physical characteristics from the recorded image of the moving object detection device 11c, the installation or use of the beacon tag 11a and the receiver 11b may be omitted.
