The present invention is not limited to the embodiments.

[Configuration of information presentation system]
FIG. 1 is a functional block diagram illustrating the configuration of the information presentation system according to the first embodiment. As shown in FIG. 1, in the information presentation system 9, the some portable terminal 1 and the server 2 are connected by radio | wireless communication. In the information presentation system 9, the probability that the server 2 is located in the area, which becomes higher toward the center of the area together with the information associated with the predetermined area (hereinafter referred to as “potential”). The defined area information is provided to the mobile terminal 1. Then, the received portable terminal 1 integrates the potential based on the position changing according to the movement of the user who owns the portable terminal 1 using the region information, and based on the accumulated potential and the user's operation state. To control the presentation of information associated with the area. For example, the mobile terminal 1 detects that the mobile terminal 1 is operating as the user's operating state during movement, stoppage, and operation. And the portable terminal 1 does not present until the accumulated potential exceeds the first level (low), and when it exceeds the first level, presents information at the timing when the user operates the portable terminal 1. In addition, when the accumulated potential is equal to or higher than the second level (medium), the mobile terminal 1 presents information at a timing when the user operates the mobile terminal 1 or when the user stops. In addition, when the accumulated potential is equal to or higher than the third level (high), the mobile terminal 1 presents information regardless of the operation state of the user. Such processing in the portable terminal 1 is hereinafter referred to as “information presentation control processing”.

[Configuration of mobile terminal]
The mobile terminal 1 corresponds to, for example, a mobile phone, but is not limited to this, and may be a PDA (Personal Digital Assistants) or a portable personal computer, and the server 2 provides information associated with the area. Any terminal can be used. Furthermore, the mobile terminal 1 includes a position sensor 10, an acceleration sensor 20, a gyro sensor 30, an output device 40, a storage unit 50, and a control unit 60.

  The position sensor 10 corresponds to a GPS sensor, for example, and acquires the current position (latitude, longitude) of the user who owns the mobile terminal 1. The acceleration sensor 20 detects acceleration in three orthogonal directions. The gyro sensor 30 detects an angular velocity. The acceleration sensor 20 and the gyro sensor 30 are used, for example, to determine the operating state of the user who owns the mobile terminal 1.

  The output device 40 corresponds to a display (or monitor, touch panel) or a speaker, and information associated with the area is presented.

  The storage unit 50 corresponds to a storage device such as a non-volatile semiconductor memory device such as a flash memory or a FRAM (registered trademark) (Ferroelectric Random Access Memory). Further, the storage unit 50 includes presentation information data 51 and user status data 52. The presentation information data 51 is data including information associated with an area to be presented to the user, information on conditions presented to the user, and information on the presented means. The presentation information data 51 includes an inner area table 511 and an outer area table 512. The inner area table 511 is presentation information data regarding an inner area indicating a main area. The outer area table 512 is presentation information data relating to an outer area indicating an area outside the inner area. The user state data 52 is data indicating the operation state of the user. Detailed description of the presentation information data 51 and the user status data 52 will be described later.

  The control unit 60 has an internal memory for storing programs defining various processing procedures and control data, and executes various processes using these. The control unit 60 corresponds to, for example, an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA) or an electronic circuit such as a central processing unit (CPU) or a micro processing unit (MPU). Furthermore, the control unit 60 includes a presentation information data acquisition unit 61, a position acquisition unit 62, a user state determination unit 63, an area entry / exit level determination unit 64, and an information presentation unit 65.

  The presentation information data acquisition unit 61 acquires presentation information data corresponding to the user who owns the mobile terminal 1 from the server 2. For example, the presentation information data acquisition unit 61 provides the presentation information corresponding to the user transmitted from the server 2 when the user registers through the portable terminal 1 to receive a service that provides information associated with various areas. Data 51 is acquired. Then, the presentation information data acquisition unit 61 stores the acquired presentation information data 51 in the storage unit 50. Here, the data structure of the presentation information data 51 will be described with reference to FIGS. 2 describes the data structure of the presentation information data 51 relating to the inner area, and FIG. 3 describes the data structure of the presentation information data 51 relating to the outer area.

  FIG. 2 is a diagram illustrating an example of the data structure of the inner area table. As shown in FIG. 2, the inner region table 511 includes inner region ID 511a, region information 511b, presentation information 511c, potential history 511d, entry / exit level 511e, entry / exit level definition 511f, presented means 511g, and outer region ID 511h. Store in association with each other. The inner area ID 511a indicates the identification ID of the main area linked to the information to be presented.

  The area information 511b is information representing the position and potential of the inner area indicated by the inner area ID. That is, in the region information 511b, a partial region in the inner region and a potential value that increases toward the center of the inner region are stored in association with each other. For example, the area information 511b has a figure having a vertex coordinate sequence and an array of potential values. As an example of how to give the potential value at each coordinate point, assuming that the film is stretched over the region, the displacement in the height direction at the boundary of the region is fixed to zero, and the film of constant tension is used. There is a method of giving it as the amplitude of natural vibration (in vibration mode 1). As another example, there is a method of giving a value proportional to the distance from the boundary of the region. Furthermore, as another example, there is a method in which a line such as a contour line is manually drawn in advance in an area. In addition, how to give the potential value at each coordinate point is not limited to these methods.

  The presentation information 511c is presentation information associated with the inner area indicated by the inner area ID. For example, when the area is a commercial area, a character string and voice such as “Store is near here”, a store map image, a store URL, and the like are set.

  The potential history 511d indicates a history of potential in the inner region indicated by the inner region ID. That is, the potential value based on the position of the user in the inner region is stored as a history in the potential history 511d.

  The entrance / exit level 511e is a degree indicating how much the user is surely entering the inner area indicated by the inner area ID. The entry / exit level 511e is set as an entry level in the case of the inner area indicated by the inner area ID. The entry / exit level 511e is set to a corresponding level among a plurality of levels defined by an entry / exit level definition 511f described later. In the case of an outer area described later, it is set as a withdrawal level.

  In the entry / exit level definition 511f, a plurality of entry / exit levels are defined. For example, the entrance / exit level is represented by three levels of “low”, “medium”, and “high”. Each level is represented by a range of potential integrated values.

  In the presented means 511g, a presentation means is set when already presented. For example, the presented means 511g may be presented to the output device 40 as an alarm using voice, melody, vibration, or the like, or may be presented to the output device 40 as a display using an image, a character string, or the like. In the case where it has not been presented yet, for example, “NULL” is set in the presented means 511g.

  The outer area ID 511h is an identification number of an outer area that is paired with the inner area indicated by the inner area ID and is associated with information to be presented. If the information to be presented is not associated, nothing is set in the outer area ID 511h.

  As an example, when the inner area ID 511a is “1”, the area information 511b is “p1 [x1, y1, x2, y2,...] Pot = 0.1 p2 [x10, y10, x11, y11,. 0.5 ... "is stored. p1 and p2 represent partial areas, and pot represents a potential value associated with the partial area. Specific presentation contents represented by “URL, application, image, character string, voice, melody, etc.” are stored as the presentation information 511c. “0.2 0.1 ··” is stored as the potential history 511d. “Medium” is stored as the entry / exit level 511e, and “Low = 2-3 Medium = 3-5 High = 5” is stored as the entry / exit level definition 511f. That is, when the range of the potential integrated value is “2-3”, the entry / exit level is defined as “low”. When the range of the potential integrated value is “3-5”, the entry / exit level is defined as “medium”. When the range of the integrated value of potential is “5”, the entry / exit level is defined as “high”. “Alarm” is stored as the presented means 511g, and “10001” is stored as the outer area ID 511h.

  FIG. 3 is a diagram illustrating an example of the data structure of the outer area table. As shown in FIG. 3, the outer area table 512 includes an outer area ID 512a, area information 512b, presentation information 512c, potential history 512d, entry / exit level 512e, entry / exit level definition 512f, presented means 512g, and valid flag 512h. The area ID 512i is stored in association with each other. The outer area ID 512a indicates an identification ID of the outer area associated with the information to be presented.

  The presentation information 512c is presentation information associated with the outer area indicated by the outer area ID. For example, when the outside area is outside the range in which movement around the child's house is permitted, a character string such as “do not go too far” and a voice are set.

  The entry / exit level 512e is a degree of accuracy indicating how reliably the user is in the outer area indicated by the outer area ID. The entry / exit level 512e is set as the withdrawal level in the case of the outer area indicated by the outer area ID. The entry / exit level 512e is set to a corresponding level among a plurality of levels defined by the entry / exit level definition 512f.

  The validity flag 512h is a flag for determining whether or not to validate the outer area indicated by the outer area ID as a target of the “information presentation control process”. For example, the validity flag 512h is set to “TRUE” when the outside area is to be validated as the target of the “information presentation control process”, and when the outside area is invalidated as the subject of the “information presentation control process”, “ "FALSE" is set.

  The inner area ID 512i is an identification number of an inner area that is paired with the outer area indicated by the outer area ID.

  As an example, when the outer area ID 512a is “10001”, the area information 512b is “p1 [x100, y100, x101, y101,...] Pot = 0.1 p2 [x110, y110, x111, y111,. 0.5 ... "is stored. p1 and p2 represent partial areas, and pot represents a potential value associated with the partial area. Specific presentation contents each represented by “URL, application, image, character string, voice, melody, etc.” are stored as the presentation information 512c. “0.2 0.1 ··” is stored as the potential history 512d. “Medium” is stored as the entry / exit level 512e, and “Low = 2-3 Medium = 3-5 High = 5” is stored as the entry / exit level definition 512f. “NULL” is stored as the presented means 512g, and “TRUE” is stored as the valid flag 512h. “1” is stored as the inner area ID 512i.

  Returning to FIG. 1, the position acquisition unit 62 acquires the position of the user acquired by the position sensor 10 every predetermined period. Then, the position acquisition unit 62 passes the acquired user position to the region entrance / exit level determination unit 64.

  The user state determination unit 63 determines the user's operation state using the acceleration detected by the acceleration sensor 20 and the angular velocity detected by the gyro sensor 30. For example, the user state determination unit 63 determines whether the user is moving, stopped, or operating the mobile terminal 1 as the operation state of the user. Then, when there is a change in the user's operation state, the user state determination unit 63 notifies the information presentation unit 65 of the change in the operation state. In the following description, the type of operation state is described as “moving” during movement, “stop” during stopping, and “operation” during operation of the mobile terminal 1, but is not limited thereto. It is not a thing.

  Each time the area entry / exit level determination unit 64 acquires the position of the user handed over from the position acquisition unit 62, the area entry / exit level determination unit 64 acquires the potential value corresponding to the acquired position from the area information 511 b of the inner area table 511. Integrate the acquired potential values. For example, the region entry / exit level determination unit 64 uses the potential value corresponding to the position acquired from the region information 511b and the potential history 511d of the inner region table 511, and the potential for the specified number from the latest to the past. Is integrated. Then, the region entry / exit level determination unit 64 updates the potential value corresponding to the position acquired from the region information 511b to the potential history 511d of the inner region table 511.

  Further, the area entry / exit level determination unit 64 determines the entry / exit level with respect to the accumulated potential value using the entry / exit level definition 511f of the inner area table 511. Furthermore, when there is a change in the determined entry / exit level, the area entry / exit level determination unit 64 notifies the information presentation unit 65 of the entry / exit level that has changed. Here, the area entry / exit level determination unit 64 determines that the outer area table 512 is valid if the outer area ID is set in the outer area ID 511h of the inner area table 511 when the entry / exit level first changes. Set the flag 512h to TRUE. That is, the area entry / exit level determination unit 64 validates the outer area as a target of the “information presentation control process”. At this time, the area entry / exit level determination unit 64 sets the presented means 512g of the outer area table 512 to “NULL” indicating that nothing has been presented yet. Thereafter, the area entry / exit level determination unit 64 determines the entry / exit level of not only the inner area but also the outer area every time the user's position is acquired. The inner area table 511 is used for the determination of the inner area entrance / exit level (referred to as “area input level determination”), while the outer area entry / exit level determination (“area exit level determination”) uses the outer area table 511. An area table 512 is used.

  Based on the entry / exit level notified from the region entry / exit level determination unit 64 and the user's operation state notified from the user state determination unit 63, the information presenting unit 65 is associated with the region targeted for the entry / exit level. Control the presentation of information. In addition, when the entrance / exit level is notified from the region entrance / exit level determination unit 64, the information presentation unit 65 is notified including whether the notification is from “region entrance level determination” or “region exit level determination”. The

  For example, when the user's operation state is notified from the user state determination unit 63, the information presentation unit 65 stores the notified user's operation state in the user state data 52 as the user state. When the entry / exit level is notified from the area entry / exit level determination unit 64, the information presentation unit 65 satisfies the correspondence between the notified entry / exit level and the user state stored in the user state data 52. It is determined whether or not. As an example, the information presentation unit 65 determines whether the user state is “operation” when the entrance / exit level is low. In other words, when the entry / exit level is low, the information presenting unit 65 can present information related to the area if the user state is “operated”. Further, the information presenting unit 65 determines whether the user state is “stop” or “operation” when the entrance / exit level is the medium level. That is, when the entry / exit level is the medium level, the information presenting unit 65 can present information regarding the area if the user state is “operation” or “stop”. Further, the information presenting unit 65 determines whether the user state is “move”, “stop”, or “operation” when the entrance / exit level is high. That is, when the entry / exit level is a high level, the information presenting unit 65 can present information regarding the region regardless of the state of the user.

  Then, if the correspondence between the entry / exit level and the user state is satisfied, the information presenting unit 65 further determines the correspondence between the user state stored in the user state data 52 and the presented means of the presentation information data 51. Determine whether it is satisfied. As an example, when the user state is “operation”, the information presentation unit 65 determines whether the presented means is “NULL” or “alarm”. That is, if the user state is “operation”, the information presenting unit 65 presents information related to the region unless “displayed” in the past. Further, the information presenting unit 65 determines whether the presented means is “NULL” when the user state is “stopped”. That is, if the user state is “stopped”, the information presenting unit 65 presents information regarding the area if it has not been presented by any means. Further, the information presenting unit 65 determines whether the presented means is “NULL” when the user state is “move”. That is, if the user state is “movement”, the information presenting unit 65 presents information regarding the region if it has not been presented by any means.

  Then, if the correspondence between the user state and the presented means is satisfied, the information presenting unit 65 presents information associated with the target area by the presenting means suitable for the user state. An example of the presentation unit suitable for the user state is to display on the mobile terminal 1 when the user state is “operation”. As an example, when the user state is “stop” or “move”, an alarm is generated using voice, melody, vibration, or the like. Then, when presenting, the information presenting unit 65 updates the presented means to the presented means of the presentation information data 51. As a result, the information presenting unit 65 can present “alarm” and “display” up to once each and prevent the same information from being presented many times.

[Server configuration]
The server 2 is a provider of information associated with an area, and corresponds to an information processing apparatus such as a personal computer or a workstation. Further, the server 2 includes a storage unit 70 and a control unit 80. The storage unit 70 corresponds to a storage device such as a non-volatile semiconductor memory element such as a flash memory or a FRAM (registered trademark) (Ferroelectric Random Access Memory). The storage unit 70 includes presentation information data 71. In the presentation information data 71, presentation information data 51 corresponding to one user is stored for a plurality of users. Note that the data structure for one user of the presentation information data 71 is the same as the data structure of the presentation information data 51, and thus the description thereof is omitted.

  The control unit 80 has an internal memory for storing programs defining various processing procedures and control data, and executes various processes using these. The control unit 80 corresponds to, for example, an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA) or an electronic circuit such as a central processing unit (CPU) or a micro processing unit (MPU). Further, the control unit 80 includes a presentation information data providing unit 81.

  The presentation information data providing unit 81 provides the presentation information data 71 corresponding to the user to the mobile terminal 1 corresponding to the user. For example, when the presentation information data providing unit 81 receives a registration request for a service that provides information associated with various areas from the mobile terminal 1 corresponding to the user, the presentation information data providing unit 81 creates the presentation information data 71 corresponding to the user in the storage unit 70. To do. Then, the stored presentation information data providing unit 81 transmits the created presentation information data 71 to the portable terminal 1 that has requested the registration request. When the presentation information in the presentation information data 71 is changed, the presentation information data providing unit 81 may provide the changed presentation information to all registered users.

[Description of area entry / exit level judgment]
Next, the area entry / exit level determination will be specifically described with reference to FIGS. 4 to 6 specifically explain the area entry level determination among the area entry / exit level determinations. 4 to 6, the region information 511b of the inner region includes a potential near the region boundary of 0.1, a region near the center of the region 1.0, and a potential between the region boundary near the center. Is defined as 0.5. The potential value is set high around the entrance / exit of the region. Further, it is assumed that “low = 0.15−0.25, medium = 0.25−0.75, high = 0.75” is stored in the entry / exit level definition 511f.

  In this way, the user owns the mobile terminal 1 and moves around the inner area where the area information is defined. When the user enters the inside of the inner area, the area entrance / exit level determination unit 64 performs area entrance level determination based on the position of the user.

  In FIG. 4, it is assumed that the user has moved from t0 to t1 to t2, and the region entrance / exit level determination unit 64 has acquired the user's position from the position acquisition unit 62 at t0, t1, and t2. In such a case, the region entry / exit level determination unit 64 acquires the value of the potential corresponding to the position of the user at time t1 as 0.1 using the region information 511b. However, the region entrance / exit level determination unit 64 does not define the potential values corresponding to the respective user positions at the times t0 and t2. 1 is calculated. Then, the area entry / exit level determination unit 64 does not determine the entry / exit level of the inner area because the integrated value 0.1 is lower than the low level.

  FIG. 5 illustrates a case where the potential gradually increases as the user moves. In the left diagram of FIG. 5, it is assumed that the user has moved from t0 → t1 → t2, and the area entry / exit level determination unit 64 has acquired the user's position from the position acquisition unit 62 at t0, t1, and t2. In such a case, the region entry / exit level determination unit 64 uses the region information 511b to obtain the potential values corresponding to the user's position at time t1 and t2 as 0.1 and 0.1, respectively. Then, the region entry / exit level determination unit 64 calculates 0.2 when past potential values are integrated at the time point t2. Then, the area entry / exit level determination unit 64 determines that the calculated integrated value 0.2 is lower than the low level lower limit 0.15 of the entry / exit level definition 511f. Then, when the operation state of the user is “operation”, that is, when the user operates the mobile terminal 1, the information presentation unit 65 presents information associated with the inner area. For example, when the area is a commercial area, a character string such as “Shop is near here”, a URL of the store, or the like is displayed on the output device 40. Note that the information presentation unit 65 does not present the information when the operation state of the user is not “operation”.

  Suppose that the operation state of the user is not “operation” at time t2. In FIG. 5, it is assumed that the user has further moved from t2 to t3, and the region entrance / exit level determination unit 64 has acquired the user's position from the position acquisition unit 62 at t3. In such a case, the region entry / exit level determination unit 64 acquires the value of the potential corresponding to the position of the user at time t3 as 0.1 using the region information 511b. Then, the region entry / exit level determination unit 64 calculates 0.3 when past potential values are integrated at time t3. Then, the area entry / exit level determination unit 64 determines that the calculated integrated value 0.3 is the intermediate level because it is greater than the lower limit 0.25 of the intermediate level of the entry / exit level definition 511f. The information presenting unit 65 presents information associated with the inner area when the user's operation state is “stopped”, that is, when the user stops. Note that the information presenting unit 65 does not present the information when the operation state of the user is “moving”.

  Suppose that the user's operation state is “moving” at time t3. In the right diagram of FIG. 5, it is assumed that the user has moved from t3 to t4, and the region entry / exit level determination unit 64 has acquired the user's position from the position acquisition unit 62 at t4. In such a case, the region entry / exit level determination unit 64 acquires the value of the potential corresponding to the position of the user at time t4 as 0.5 using the region information 511b. Then, the region entry / exit level determination unit 64 calculates 0.8 when the past potential values are integrated at time t4. Then, the region entry / exit level determination unit 64 determines that the calculated integrated value 0.8 is higher than the lower limit 0.75 of the high level of the entry / exit level definition 511f. Then, the information presenting unit 65 presents information associated with the inner area regardless of the user's operating state.

  FIG. 6 illustrates a case where the potential increases at once due to the movement of the user. In FIG. 6, it is assumed that the user has moved from t0 to t1 due to the movement of the user, and the region entrance / exit level determination unit 64 has acquired the user's position from the position acquisition unit 62 at t1. In such a case, the region entry / exit level determination unit 64 acquires the value of the potential corresponding to the position of the user at time t1 as 1.0 using the region information 511b. Then, the region entrance / exit level determination unit 64 calculates 1.0 when past potential values are integrated at the time point t1. Then, the area entry / exit level determination unit 64 determines that the calculated integrated value 1.0 is higher than the lower limit 0.75 of the low level of the entry / exit level definition 511f. Then, the information presenting unit 65 presents information associated with the inner area regardless of the user's operating state. For example, when the area is a commercial area, a sound such as “Shop is near here” is output to the output device 40.

  In FIG. 7, the region exit level determination among the region entrance / exit level determination will be specifically described. In FIG. 7, the region information 512b of the outer region defines the potential near the region boundary as 0.1 and the potential as 0.5 and 1.0 as the region boundary is moved away. The potential value is set high around the entrance / exit of the region. Further, it is assumed that “low = 0.15−0.25, medium = 0.25−0.75, high = 0.75” is stored in the entry / exit level definition 512f.

  When the entrance / exit level of the inner region becomes a low level or more, the region entrance / exit level determination unit 64 starts the region exit level determination based on the position of the user.

  In FIG. 7, it is assumed that the user has moved from the inner area to the outer area as t0 → t1, and the area entrance / exit level determination unit 64 acquires the user's position from the position acquisition unit 62 at t1. In this case, the region entry / exit level determination unit 64 acquires the value of the potential corresponding to the position of the user at time t1 as 0.5 using the region information 512b. Then, the region entrance / exit level determination unit 64 calculates 0.5 when past potential values are integrated at the time point t1. Then, the area entry / exit level determination unit 64 determines the medium level because the calculated integrated value 0.5 is larger than the lower limit 0.25 of the medium level of the entry / exit level definition 512f. Then, when the user's operation state is “stopped”, that is, when the user stops, the information presenting unit 65 presents information associated with the outer area. For example, when the outside area is outside the permitted range of movement around the child's house, a voice such as “Do not go too far” is output to the output device 40. If the information presentation unit 65 determines that the entry / exit level is low, the character string or the like is displayed on the output device 40 at a timing when the operation state of the user is “operation”.

[Procedure for area entry / exit level judgment]
Next, the procedure of the region entry / exit level determination process by the region entry / exit level determination unit 64 will be described with reference to FIGS. 8 and 9. 8 and 9 are flowcharts showing the procedure of the area entry / exit level determination process.

  First, the area entry / exit level determination unit 64 determines whether or not the user's position has been acquired from the position acquisition unit 62 (step S11). When it is determined that the user's position has not been acquired (step S11; No), the area entry / exit level determination unit 64 repeats the determination process until the user's position is acquired.

  On the other hand, when it is determined that the position of the user has been acquired (step S11; Yes), the area entry / exit level determination unit 64 determines whether the validity flag 512h of the outer area table 512 is “TRUE” (step S11). S12). When it is determined that the validity flag 512h of the outer region table 512 is not “TRUE” (step S12; No), the region entry / exit level determination unit 64 proceeds to step S20 to perform region entry level determination.

  When it is determined that the validity flag 512h of the outer area table 512 is “TRUE” (step S12; Yes), the area entry / exit level determination unit 64 proceeds to step S13 to perform area exit level determination. In step S13, the area entry / exit level determination unit 64 determines whether or not the presented means 512g of the outer area table 512 is “display” (step S13).

  When it is determined that the presented means 512g of the outer area table 512 is “display” (step S13; Yes), the area entry / exit level determination unit 64 sets the validity flag 512h of the outer area table 512 to “FALSE”. (Step S14). Since the area entry / exit level determination unit 64 has already presented the information associated with the outside area, the area entry / exit level determination unit 64 invalidates the area entry / exit level determination. Then, the area entry / exit level determination unit 64 proceeds to step S20 in order to perform area entry level determination.

  On the other hand, when it is determined that the presented means 512g of the outer region table 512 is not “display” (step S13; No), the region entrance / exit level determination unit 64 determines the potential value corresponding to the acquired user position. Obtained from the area information 512b of the outer area table 512. Then, the region entrance / exit level determination unit 64 integrates the acquired potential values (step S15). For example, the region entry / exit level determination unit 64 uses the acquired potential value and the potential history 512d of the outer region table 512 to integrate the specified number of potential values from the latest to the past.

  Then, the area entry / exit level determination unit 64 calculates an entry / exit level for the accumulated potential value using the entry / exit level definition 512f of the outer area table 512 (step S16). Then, the area entry / exit level determination unit 64 updates the presentation information data 51 (step S17). That is, the area entry / exit level determination unit 64 updates the acquired potential value to the potential history 512d in the outer area table 512, and updates the calculated entry / exit level to the entry / exit level 512e.

  Subsequently, the area entry / exit level determination unit 64 determines whether or not the calculated entry / exit level has changed (step S18). When it is determined that the calculated entry / exit level has changed (step S18; Yes), the area entry / exit level determination unit 64 notifies the information presenting unit 65 of the change in entry / exit level (step S19). Then, the area entry / exit level determination unit 64 proceeds to step S20 in order to perform area entry level determination.

  On the other hand, when it is determined that there is no change in the calculated entry / exit level (step S18; No), the region entry / exit level determination unit 64 performs region entry level determination without notifying the information presentation unit 65 of the entry / exit level. Therefore, the process proceeds to step S20.

  Subsequently, the area entry / exit level determination unit 64 acquires the value of the potential corresponding to the acquired user position from the area information 511 b of the inner area table 511. Then, the region entrance / exit level determination unit 64 integrates the acquired potential values (step S20). For example, the region entry / exit level determination unit 64 uses the acquired potential value and the potential history 511d of the inner region table 511 to integrate the potential values for the designated number from the latest to the past.

  Then, the area entry / exit level determination unit 64 calculates an entry / exit level for the accumulated potential value using the entry / exit level definition 511f of the inner area table 511 (step S21). Then, the area entry / exit level determination unit 64 updates the presentation information data 51 (step S22). That is, the area entry / exit level determination unit 64 updates the acquired potential value to the potential history 511d in the inner area table 511, and updates the calculated entry / exit level to the entry / exit level 511e.

  Subsequently, the area entry / exit level determination unit 64 determines whether or not to update the presented means 511g of the inner area table 511 to “NULL” (step S23). For example, the area entry / exit level determination unit 64 updates the presented means 511g to “NULL” when the calculated entry / exit level becomes less than the low level. In such a case, even if the user once leaves the inner area, information may be presented when the user enters the inner area again. Note that the region entrance / exit level determination unit 64 may update the presented means 511g to “NULL” after a certain period of time after it has become low level. In such a case, once the information is presented, the information is not presented for a while. Further, the area entry / exit level determination unit 64 may update the presented means 511g to “NULL” when it is away from the inner area by a certain distance or more. Furthermore, the area entry / exit level determination unit 64 may not update the presented means 511g to “NULL”. In such a case, once the information is presented, the information is not presented again. The determination as to whether or not to update to “NULL” of the presented means 511g may be made, for example, depending on the application.

  Subsequently, the area entry / exit level determination unit 64 determines whether or not the calculated entry / exit level has changed (step S24). When it is determined that there is no change in the calculated entry / exit level (step S24; No), the region entry / exit level determination unit 64 ends the process.

  On the other hand, when it is determined that the calculated entrance / exit level has changed (step S24; Yes), the region entrance / exit level determination unit 64 notifies the information presenting unit 65 of the entry / exit level having changed (step S25). . Then, the region entry / exit level determination unit 64 determines whether or not the outer region ID 511h of the inner region table 511 has an outer region ID (step S26).

  When it is determined that the outer region ID 511h of the inner region table 511 has an outer region ID (step S26; Yes), the region entry / exit level determination unit 64 sets the effective flag of the region of the outer region ID to TRUE and has been presented. Is set to NULL (step S27). That is, the area entry / exit level determination unit 64 updates the valid flag 512h in the record corresponding to the outer area ID of the outer area table 512 to “TRUE” and updates the presented means 512g to “NULL”. Then, the area entry / exit level determination unit 64 ends the process.

  On the other hand, when it is determined that the outer area ID 511h of the inner area table 511 does not have an outer area ID (step S26; No), the area entrance / exit level determination unit 64 ends the process.

[Information presentation process procedure]
Next, the procedure of information presentation processing by the information presentation unit 65 will be described with reference to FIG. FIG. 10 is a flowchart showing the procedure of the information presentation process.

  First, the information presentation unit 65 determines whether or not a user state (user operation state) that has changed has been notified (step S31). When it is determined that the user state that has changed is not notified (step S31; No), the information presenting unit 65 repeats the determination process until the user state that has changed is notified. On the other hand, when it is determined that the user state that has changed is notified (step S31; Yes), the information presenting unit 65 updates the notified user state to the user state data 52 (step S32), and proceeds to step S34. To do.

  On the other hand, the information presentation unit 65 determines whether or not an entry / exit level that has changed has been notified (step S33). If it is determined that the changed entry / exit level is not notified (step S33; No), the information presenting unit 65 repeats the determination process until the changed entry / exit level is notified. On the other hand, if it is determined that the entry / exit level that has changed is notified (step S33; Yes), the information presenting unit 65 proceeds to step S34. The information presenting unit 65 receives a notification including whether the notification is from the “region entrance level determination” or the “region exit level determination” along with the entry / exit level that has changed.

  In step S34, the information presentation unit 65 determines whether or not the correspondence between the entry / exit level and the user state is OK (step S34). As an example, when the entry / exit level is low, the information presenting unit 65 determines whether the user state is “operation” in which the mobile terminal 1 is being operated. Further, when the entrance / exit level is the medium level, the information presenting unit 65 determines whether the user state is “stop” in which the user state is stopped or “operation” in which the mobile terminal 1 is being operated. In addition, when the entry / exit level is high, the information presenting unit 65 is “moving” in which the user state is moving, “stopping” in which the user state is stopped, or “operation” in which the mobile terminal 1 is being operated. Determine if there is.

  When it is determined that the correspondence between the entry / exit level and the user state is not OK (step S34; No), the information presenting unit 65 does not match the presenting condition, and thus ends the process. On the other hand, when it is determined that the correspondence between the entry / exit level and the user state is OK (step S34; Yes), the information presenting unit 65 determines whether or not the correspondence between the user state and the presented means is OK ( Step S35). In the case of notification from “area entry level determination”, the already-presented means 511 g of the inner area table 511 is used as the presented means, and in the case of notification from “area withdrawal level determination”, the outer area table 512 Presented means 512g is used.

  As an example, when the user state is “operation”, the information presentation unit 65 determines whether the presented means is “NULL” or “alarm”. Further, the information presenting unit 65 determines whether the presented means is “NULL” when the user state is “stopped”. Further, the information presenting unit 65 determines whether the presented means is “NULL” when the user state is “move”.

  When it is determined that the correspondence between the user status and the presented means is not OK (step S35; No), the information presenting unit 65 does not match the presenting condition, and thus ends the process. On the other hand, when it is determined that the correspondence between the user state and the presented means is OK (step S35; Yes), the information presentation unit 65 presents the presentation information according to the user state (step S36). In addition, as the presentation information, the presentation information 511c of the inner area table 511 is used in the case of notification from “area entering level determination”, and the presentation information of the outer area table 512 in the case of notification from “area withdrawal level determination”. 512c is used.

  As an example, the information presentation unit 65 displays the presentation information on the output device 40 when the user state is “operation”. In addition, when the user state is “stop” or “move”, the information presentation unit 65 presents the presentation information to the output device 40 with an alarm using voice, melody, vibration, or the like.

  Thereafter, the information presentation unit 65 updates the presentation information data 51 (step S37). That is, in the case of notification from “area entering level determination”, the information presenting unit 65 updates the presented means to the presented means 511 g in the inner area table 511. In the case of notification from “area withdrawal level determination”, the information presenting unit 65 updates the presented means to the presented means 512g in the inner area table 512. And the information presentation part 65 complete | finishes a process.

  By the way, it has been described that the area entrance / exit level determination unit 64 integrates the value of the potential corresponding to the position of the user acquired from the position sensor 10, that is, one point of position information. However, the region entry / exit level determination unit 64 is not limited to this, and the potential may be calculated by another integration method.

  FIG. 11 is a diagram for explaining another potential accumulation method in the region entrance / exit level determination unit 64. As illustrated in FIG. 11, the region entrance / exit level determination unit 64 creates a normal distribution centered on the user's position with the accuracy of the user's position acquired from the position sensor 10 as a variance. Then, the region entry / exit level determination unit 64 sets the volume P of the portion where the created normal distribution shape and the potential (region information 511b) relating to the region overlap as the value of the potential at that position. Then, the area entry / exit level determination unit 64 integrates the potential values calculated for each position of the user acquired from the position sensor 10. Thereby, taking into account measurement errors when acquiring the position of the position sensor 10, the potential values at the acquired positions are integrated, so that the potential corresponding to the position of the user can be calculated strictly. As a result, when it is determined that the user has entered the area, the mobile terminal 1 can accurately suppress the information associated with the area from being presented uniformly.

[Effect of Example 1]
According to the first embodiment, in the presentation information data 51, as the region information, the potential value that increases toward the center of the region is stored in association with the partial region in the region. Then, each time the position acquisition unit 62 acquires the user's position, the region entry / exit level determination unit 64 acquires the potential value corresponding to the acquired position from the region information, and integrates the acquired potential value. . The information presentation unit 65 controls the presentation of information associated with the region based on the accumulated potential value and the operation state determined by the user state determination unit 63. According to such a configuration, when the user enters the area, the information presenting unit 65 can prevent the information associated with the area from being presented uniformly. For example, even when the user hits the area or there is a position detection error, the information presenting unit 65 immediately presents information associated with the area when it is determined that the user has entered the area. This can be suppressed.

  Further, according to the first embodiment, the region entrance / exit level determination unit 64 determines whether or not the accumulated potential value exceeds a predetermined threshold value. Then, when it is determined that the accumulated value of the potential exceeds a predetermined threshold, the information presenting unit 65 displays information associated with the region according to the user's operation state determined by the user state determination unit 63. Present. According to such a configuration, the information presenting unit 65 uniformly presents information regardless of the accumulated value of the potential by using a predetermined threshold for comparison with the accumulated value of the potential. Can be suppressed.

  Further, according to the first embodiment, the region entrance / exit level determination unit 64 determines whether or not the accumulated value of the potential exceeds the lower limit of the low level. When the accumulated value of the potential exceeds the lower limit of the low level, the information presenting unit 65 automatically displays the information associated with the area according to the user's operation state when the user's operation state is the operation of the own terminal. Present to the terminal. The area entry / exit level determination unit 64 determines whether the accumulated value of the potential exceeds the lower limit of the medium level. Then, when the accumulated value of the potential exceeds the lower limit of the middle level, the information presenting unit 65 displays information associated with the area according to the user's operation state when the user's operation state is operation or stop of the own terminal. And present it to your terminal. The area entry / exit level determination unit 64 determines whether or not the accumulated value of the potential exceeds the lower limit of the high level. Then, when the accumulated value of the potential exceeds the lower limit of the high level, the information presenting unit 65 presents the information associated with the area to the own terminal regardless of the user's operation state. According to such a configuration, when the accumulated value of potential exceeds each level, the information presenting unit 65 changes the means for presenting information according to the user's operating state. Can present well.

  Further, according to the first embodiment, in the presentation information data 51, as region information, a potential value that increases toward the outside of the region is stored in association with a partial region outside the region. . When the region entrance / exit level determination unit 64 determines that the accumulated value of the potential has exceeded the lower limit of the low level, the region entry / exit level determination unit 64 performs processing by the region entry / exit level determination unit 64 and the information presenting unit 65. Start processing. According to such a configuration, the information presenting unit 65 can present information associated with the outside of the area as well as the outside of the area, so that the service is presented to the user with respect to the area. it can.

  By the way, in the information presentation system 9 according to the first embodiment, the mobile terminal 1 acquires the presentation information data 51 including information associated with the area from the server 2 in advance, and uses the acquired presentation information data 51 to It explained that it controls the presentation of information to the user. However, the information presentation system 9 is not limited to this, and the server 2 controls the presentation of the information to the user (mobile terminal 1) using the presentation information data 51 including the information associated with the area. May be. Therefore, in the second embodiment, an information presentation system 9A in which the server 2 controls presentation of the information to the user (mobile terminal 1) using the presentation information data 51 including information associated with the area will be described.

[Information Presentation System According to Second Embodiment]
FIG. 12 is a functional block diagram illustrating the configuration of the information presentation system according to the second embodiment. In addition, about the structure same as the information presentation system 9 shown in FIG. 1, it attaches | subjects the same code | symbol and abbreviate | omits the description of the overlapping structure and operation | movement. The difference between Example 1 and Example 2 is that the area entry / exit level determination unit 64 and the information presentation unit 65 of the mobile terminal 1A are deleted, and the position / user state transmission unit 91 and the information acquisition unit 92 are added. is there. Further, the difference between the first embodiment and the second embodiment is that the presentation information data 51 and the user status data 52 of the portable terminal 1A are deleted. The difference between the first embodiment and the second embodiment is that the presentation information data providing unit 81 of the server 2A is deleted and an area entry / exit level determination unit 93 and an information presentation unit 94 are added. Further, the difference between the first embodiment and the second embodiment is that user status data 72 is added to the storage unit 70 of the server 2A.

  The position / user state transmission unit 91 transmits the acquired user position to the server 2 </ b> A each time the user position delivered from the position acquisition unit 62 is acquired. Further, the position / user state transmission unit 91 transmits the user operation state notified from the user state determination unit 63 to the server 2A.

  The information acquisition unit 92 acquires information and presentation means associated with the area from the server 2A. And the information acquisition part 92 presents the information linked | related with the acquired area | region with the acquired presentation means.

  Each time the region entrance / exit level determination unit 93 receives the position of the user transmitted from the position / user state transmission unit 91, for the inner region, the region entry / exit level determination unit 93 displays the potential value corresponding to the acquired position in the region information 711 b of the inner region table 711. And the obtained potential values are integrated. Then, the area entry / exit level determination unit 93 determines an entry / exit level from the accumulated potential value, and notifies the information presenting unit 94 of the determined entry / exit level. Note that the processing of the region entrance / exit level determination unit 93 is the same as the processing of the region entrance / exit level determination unit 64, and thus description thereof is omitted.

  Based on the entry / exit level notified from the region entry / exit level determination unit 93 and the user's operation state notified from the user state determination unit 63, the information presentation unit 94 associates the information presentation unit 94 with the region targeted for the entry / exit level. The information presented to the portable terminal 1A is controlled. Then, when presenting information as a result of the control, the information presenting unit 94 transmits information associated with the region and a presenting means for presenting the information to the corresponding portable terminal 1A. Note that the processing of the information presentation unit 94 is the same as the processing of the information presentation unit 65, and thus the description thereof is omitted.

[Effect of Example 2]
According to the second embodiment, the presentation information data 71 stores, as region information, a potential value that becomes higher toward the center of the region in association with a partial region in the region. Then, each time the region entrance / exit level determination unit 93 detects the position of the user transmitted from the mobile terminal 1 </ b> A, the region entrance / exit level determination unit 93 acquires the potential value corresponding to the detected position from the presentation information data 71. Accumulate. And the information presentation part 94 controls the presentation to 1 A of portable terminals about the information tied to the area | region based on the value of the accumulated potential, and the operation state of the user of 1 A of portable terminals. According to such a configuration, even if a user who owns the mobile terminal 1A enters the area, the server 2A does not uniformly present information associated with the area to the mobile terminal 1A. As a result, the mobile terminal 1 </ b> A provided with the information can suppress uniform presentation of information associated with the area even if a user who owns the terminal enters the area.

[Programs]
In addition, although the user state determination part 63 was arrange | positioned in the portable terminals 1 and 1A, you may make it arrange | position in the servers 2 and 2A. In such a case, the servers 2 and 2A acquire the acceleration detected by the acceleration sensor 20 and the angular velocity detected by the gyro sensor 30 from the mobile terminals 1 and 1A, and use the acquired acceleration and angular velocity to determine the operation state of the user. Judgment is sufficient.

  In addition, each component of each illustrated apparatus does not necessarily need to be physically configured as illustrated. That is, the specific mode of distribution / integration of each device is not limited to that shown in the figure, and all or a part thereof may be functionally or physically distributed or arbitrarily distributed in arbitrary units according to various loads or usage conditions. Can be integrated and configured. For example, the position acquisition unit 62 and the area entry / exit level determination unit 64 may be integrated as one unit. On the other hand, the region entry / exit level determination unit 64 may be distributed into region exit level determination processing and region entry level determination processing. Further, a storage unit such as the presentation information data 51 may be connected as an external device of the mobile terminal 1 via a network.

  The various processes described in the above embodiments can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. Therefore, in the following, an example of a computer that executes an information presentation program that realizes the same function as the portable terminal 1 illustrated in FIG. 1 will be described. FIG. 13 is a diagram illustrating an example of a computer that executes an information presentation program.

  As illustrated in FIG. 13, the computer 200 includes a CPU 201 that executes various arithmetic processes, an input device 202 that receives data input from a user, and a display 203. The computer 200 also includes a reading device 204 that reads a program and the like from a storage medium, and an interface device 205 that exchanges data with other computers via a network. The computer 200 also includes a RAM 206 that temporarily stores various information and a hard disk device 207. The devices 201 to 207 are connected to the bus 208.

  The hard disk device 207 stores an information presentation program 207a and information presentation related information 207b. The CPU 201 reads the information presentation program 207 a and develops it in the RAM 206. The information presentation program 207a functions as an information presentation process 206a.

  For example, the information presentation process 206 a corresponds to the presentation information data acquisition unit 61, the position acquisition unit 62, the user state determination unit 63, the area entry / exit level determination unit 64, and the information presentation unit 65.

  Note that the information presentation program 207a is not necessarily stored in the hard disk device 207 from the beginning. For example, each program is stored in a “portable physical medium” such as a flexible disk (FD), a CD-ROM, a DVD disk, a magneto-optical disk, and an IC card inserted into the computer 200. Then, the computer 200 may read and execute the information presentation program 207a from these.
