  Regional information and peripheral information based on position information are often acquired from a data center or the like via a communication network. On the other hand, computer graphics and images are often used as content, and the data capacity of the content tends to increase. Further, when HMD (Head Mounted Display) or the like becomes widespread in the future, there is a possibility that data communication is constantly performed in order to display the content.

  In order to efficiently use the communication network and optimize search information, it is necessary to optimize the communication frequency and communication amount of the peripheral information search. For that purpose, it is important to narrow down the search range to some extent and to expand the search range according to the situation. On the other hand, when it is necessary to constantly check the data, it is inefficient to request the user to perform the operation each time, which may hinder the spread of services to the user.

  For example, in the general system described in Patent Document 2, when searching for peripheral information based on position information, a certain range of information is searched based on the position information. However, when there is no information corresponding to the information in the searched range, the user needs to perform an operation for expanding the search range and make a search request again.

  In order to avoid such an operation load on the user, a method of performing a search by expanding the range in advance on the system side is also conceivable. However, as described above, the communication frequency increases due to an increase in the search processing and the amount of result data. It becomes a problem.

Further, if the peripheral information cannot be appropriately provided unless the user moves, there is a problem that a burden is imposed on the user.

  Therefore, the present invention provides a peripheral information search device, a peripheral information search system, a portable terminal, and a peripheral information search device that can search peripheral information in an appropriate range without burdening the user even when the user is not moving.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Embodiment 1. FIG.
FIG. 1 is a block diagram showing an example of a peripheral information search system in the first embodiment of the present invention. The peripheral information search system in this embodiment includes a mobile terminal 10 and a peripheral information search system 20. The portable terminal 10 and the peripheral information search system 20 are connected to each other via the communication network 30.

  The mobile terminal 10 is a terminal device that is carried by a user. The portable terminal 10 includes an information management unit 11, a communication unit 12, a GPS sensor 13, an acceleration sensor 14, an electronic compass 15, and a display device 16.

  The GPS sensor 13 detects information indicating the user's position (hereinafter referred to as position information). In the present embodiment, a case where the position information of the user is detected using a GPS sensor will be described. However, any sensor other than the GPS sensor may be used as long as it can detect the user's position information.

  The acceleration sensor 14 recognizes the movement state of the user. Specifically, the acceleration sensor 14 detects acceleration information or the like for performing behavior estimation of whether the user is moving or stopped. The acceleration sensor 14 may determine that the user is not moving (that is, in a stopped state) when the acceleration is zero for a predetermined time. In the present embodiment, a case will be described in which the movement state of a user is authorized using an acceleration sensor. However, any sensor other than the acceleration sensor may be used as long as it can recognize the movement state of the user.

  The electronic compass 15 detects information indicating the direction in which the user is facing (hereinafter referred to as direction information). Specifically, the electronic compass 15 detects the direction in which the mobile terminal 10 carried by the user is facing. In addition, in order for the electronic compass 15 to detect the direction in which the user is facing correctly, the user may hold the mobile terminal 10 in a predetermined direction. In the present embodiment, a case where direction information of a user is detected using an electronic compass will be described. However, any means other than the electronic compass may be used as long as it can detect the direction information of the user.

  The information management unit 11 estimates a user's behavior and creates a condition (hereinafter referred to as a search condition) that causes the peripheral information search system 20 to search for peripheral information. The search condition includes at least user position information.

  Specifically, when the information management unit 11 estimates that the user (more specifically, the mobile terminal 10) is moving within a certain time based on the acceleration information detected by the acceleration sensor 14, the information management unit 11 searches for peripheral information. The position information is transmitted to the system 20. On the other hand, when the information management unit 11 estimates that the user (more specifically, the portable terminal 10) is stopped within a certain time based on the acceleration information detected by the acceleration sensor 14, the position information and the electronic compass 15 Is transmitted to the peripheral information search system 20.

  That is, when the acceleration sensor 14 recognizes that the user is not moving (that is, in a stopped state), the information management unit 11 uses the position information and the direction information detected by the electronic compass 15 as the search conditions to obtain the peripheral information. It transmits to the search system 20.

  Further, the information management unit 11 causes the display device 16 to display the search result of the peripheral information searched by the peripheral information search system 20 (hereinafter referred to as the peripheral information search result). The information management means 11 is realized by a CPU of a computer that operates according to a program. For example, the program may be stored in a storage unit (not shown) of the mobile terminal 10, and the CPU may read the program and operate as the information management unit 11 according to the program.

  The communication unit 12 transmits the search condition created by the information management unit 11 to the peripheral information search system 20. Further, the communication unit 12 notifies the information management unit 11 of the peripheral information search result received from the peripheral information search system 20.

  The display device 16 displays the search result of the peripheral information received from the peripheral information search system 20. The display device 16 is realized by, for example, a liquid crystal display. The contents of the peripheral information displayed on the display device 16 will be described later.

  The peripheral information search system 20 searches the user's peripheral information based on a request from the mobile terminal 10. The peripheral information search system 20 includes an information search means 21, a communication means 22, and a peripheral information database storage unit (hereinafter referred to as a peripheral information DB) 23.

  The communication unit 22 notifies the information search unit 21 of the information received from the mobile terminal 10. In addition, the communication unit 22 transmits the search result of the peripheral information by the information search unit 21 to the mobile terminal 10 via the communication network 30.

  The peripheral information DB 23 stores information provided to the user in association with the position information of the information. Examples of information provided to the user include commercial facilities such as restaurants and public facilities. Further, the peripheral information DB 23 may store information such as an accident site as information to be provided to the police and local government staff. Furthermore, the information provided to the user may include descriptions of exhibits and products in the exhibition facility or store facility. Information provided to the user and position information of the information are stored in advance in the peripheral information DB 23 by an administrator or the like.

  The information search means 21 determines a search range for searching for peripheral information based on the search condition received from the mobile terminal 10. Then, the information search means 21 searches for peripheral information included in the search range.

  Specifically, upon receiving a search condition including position information from the mobile terminal 10, the information search unit 21 determines a search range based on the position information and searches for peripheral information included in the search range. At that time, the information search means 21 may determine a range from the position indicated by the received position information to a predetermined distance as the search range. FIG. 2 is an explanatory diagram illustrating an example of a search range in the moving state. The example illustrated in FIG. 2 indicates that a range having a radius of 100 m from the terminal position indicated by the position information received from the mobile terminal 10 is determined as the search range for the peripheral information. In this case, the information search unit 21 searches the peripheral information DB 23 for peripheral information included in the determined search range, and notifies the communication unit 22 of the search result.

  FIG. 3 is an explanatory diagram illustrating an example in which the display device 16 displays peripheral information included in the search range illustrated in FIG. The mobile terminal screen image illustrated in FIG. 3 is an example of the content displayed on the display device 16 and indicates the facility indicated by the peripheral information and the distance to the facility. The search range shown in the example of FIG. 2 is a range with a radius of 100 m centered on the terminal position. In the search range, there is a station at a position 30 m from the terminal position and a pub at a position 85 m from the terminal position. Indicates that

  Further, when the information search means 21 receives a search condition including position information and direction information from the mobile terminal 10 (that is, when the mobile terminal 10 is in a stopped state), the search range of the direction indicated by the direction information is in another direction. The search range is determined so as to be wider. Specifically, the information search means 21 determines a range from the position indicated by the received position information to a distance that is longer by a predetermined length than the predetermined distance to the direction indicated by the direction information. May be.

  FIG. 4 is an explanatory diagram illustrating an example of a search range in the stopped state. The example shown in FIG. 4 indicates that an ellipse having the direction indicated by the direction information as the major axis and the minor axis in the direction perpendicular to the major axis is determined as the search range. The search range illustrated in FIG. 4 is a range indicated by an ellipse having a minor axis of 100 m and a major axis of 200 m, and the terminal position is a point moved by 100 m in a direction opposite to the direction indicated by the direction information on the major axis. Equivalent to. Also in this case, the information search unit 21 searches the peripheral information DB 23 for peripheral information included in the determined search range, and notifies the communication unit 22 of the search result.

  FIG. 5 is an explanatory diagram illustrating an example in which the display device 16 displays peripheral information included in the search range illustrated in FIG. The mobile terminal screen image illustrated in FIG. 5 is an example of the content displayed on the display device 16 as in FIG. 3, and indicates the facility indicated by the peripheral information and the distance to the facility. The search range illustrated in FIG. 4 is wider than the other search directions in the direction indicated by the direction information, compared to the search range illustrated in FIG. Therefore, the peripheral information illustrated in FIG. 3 does not include a convenience store (convenience store) located at a position 240 m from the terminal position, but is included in the peripheral information illustrated in FIG.

  As described above, in the present embodiment, attention is paid to the sensor of the mobile terminal 10 (for example, the GPS sensor 13, the acceleration sensor 14, and the electronic compass 15) and the movement of the person estimated from the information detected by the sensor. . Specifically, when the user is in a stopped state, it is assumed that the user has not determined a destination and is seeking a wider range of information. Therefore, optimizing the operability and communication efficiency is achieved by synchronizing the movement of the user with the search range of the peripheral information.

  The information search means 21 is realized by a CPU of a computer that operates according to a program (peripheral information search program). For example, the program may be stored in a storage unit (not shown) of a server device that implements the peripheral information search system 20, and the CPU may read the program and operate as the information search unit 21 according to the program.

  Next, the operation will be described. FIG. 6 is a sequence diagram showing an operation example of the peripheral information search system in the present embodiment. First, the position information acquired by the GPS sensor 13 is notified to the information management means 11 (step S1). Further, the sensor information (specifically, acceleration information) acquired by the acceleration sensor 14 is notified to the information management means 11 (step S2).

  First, an operation when searching for peripheral information while the user is moving (that is, when the user is in a moving state) will be described. The information management means 11 estimates behavior information based on the sensor information acquired by the acceleration sensor 14, and recognizes that the user is in a moving state (step S3). Then, the information management unit 11 transmits the position information to the peripheral information search system 20 (more specifically, the information search unit 21) (step S4).

  The information search means 21 determines a search range based on the received position information, searches the area information DB 23, and acquires peripheral information included in the search range (step S5). And the information search means 21 transmits the acquired periphery information to the portable terminal 10 (more specifically, the information management means 11) (step S6). When receiving the peripheral information, the information management means 11 displays the peripheral information on the display means 16 (step S7).

  Next, an operation when searching for peripheral information while the user is stopped (that is, when the user is in a stopped state) will be described. The operation for notifying the information management means 11 of the position information and the sensor information is the same as in steps S1 to S2.

  The information management means 11 estimates behavior information based on the sensor information acquired by the acceleration sensor 14, and recognizes that the user is in a stopped state (step S8). At this time, the electronic compass 15 notifies the information management means 11 of the acquired direction information (step S9). Then, the information management unit 11 transmits the position information and the direction information to the peripheral information search system 20 (more specifically, the information search unit 21) (step S10).

  The information search means 21 determines a search range based on the received position information and direction information, searches the area information DB 23, and acquires peripheral information included in the search range (step S11). And the information search means 21 transmits the acquired periphery information to the portable terminal 10 (more specifically, the information management means 11) (step S12). When receiving the peripheral information, the information management means 11 displays the peripheral information on the display means 16 (step S13).

  Next, the operation of the mobile terminal 10 will be described in detail. FIG. 7 is a flowchart showing an operation example of the mobile terminal 10 in the present embodiment. First, the information management means 11 acquires the position information detected by the GPS sensor 13 (step S71). Next, the information management means 11 acquires acceleration information detected by the acceleration sensor 14 (step S72), and determines whether or not the user is in a stopped state (step S73). Specifically, the information management unit 11 continues the preset time and the acceleration is not zero (that is, even if the acceleration is zero or the acceleration is zero, the information management means 11 does not perform the preset time. If not, it is determined that the user is not in a stopped state.

  When the user is not in the stop state (“non-stop state” in step S73), the information management unit 11 notifies the communication unit 12 of the position information acquired in step S72, and the communication unit 12 transmits the position information to the periphery. It transmits to the information search system 20 (step S74). When the time when the acceleration is 0 has not reached the preset time, the information management unit 11 measures the number of hours when the acceleration is 0. This measurement result is used when determining whether or not the vehicle is stopped in step S73.

  On the other hand, when the user is in a stopped state in step S73 (“stopped state” in step S73), the information management unit 11 acquires direction information detected by the electronic compass 15 (step S75). Then, the information management unit 11 notifies the communication unit 12 of the position information acquired in step S72 and the direction information acquired in step S75, and the communication unit 12 transmits the position information and direction information to the peripheral information search system 20. (Step S76).

  Thereafter, when the communication unit 12 receives the search result of the peripheral information from the peripheral information search system 20 (step S77), the information management unit 11 displays the peripheral information on the display unit 16 (step S78). Thereafter, the information management unit 11 interrupts the processing for a preset time (timer) number (step S78). Henceforth, the portable terminal 10 repeats a process from step S71.

  As described above, according to the present embodiment, the information management unit 11 transmits at least the position information detected by the GPS sensor 13 to the peripheral information search system 20. And the information search means 21 determines a search range based on the positional information received from the portable terminal 10, and searches the surrounding information contained in the search range. Further, when the acceleration sensor 14 recognizes the stop state of the user, the direction information and the position information detected by the electronic compass 15 are transmitted to the peripheral information search system 20. And the information search means 21 determines a search range so that the search range of the direction which direction information shows is wider than another direction. With the configuration described above, even if the user is not moving, it is possible to search for peripheral information in an appropriate range without imposing a burden on the user.

  Further, according to the present embodiment, when the peripheral information search system 20 receives position information from the mobile terminal 10, the information search means 21 determines a search range based on the position information and is included in the search range. Search nearby information. Then, when determining the search range, when the peripheral information search system 20 receives the direction information from the mobile terminal 10, the information search means 21 makes the search range of the direction indicated by the direction information wider than other directions. The search range is determined as follows. Even in such a configuration, when the user is not moving, it is possible to search for peripheral information in an appropriate range without imposing a burden on the user.

  That is, according to the present embodiment, after displaying the search result of the peripheral information, when it is estimated that there is no movement by the acceleration sensor 14 or the like, the direction in which the mobile terminal 10 is currently facing (that is, the electronic compass 15 The search range of the peripheral information in the direction indicated by the direction information acquired by automatically expands the search range. Therefore, it is possible to perform a search again for peripheral information that matches the user's action without any user operation.

  Further, according to the present embodiment, when expanding the search range, information is automatically narrowed down by the direction of the person. This eliminates the need for an operation on the mobile terminal side that expands the search range of peripheral information, thereby improving user operability. Furthermore, since the peripheral information is searched according to the user's action, the line utilization rate can be improved.

In addition, about the structure similar to 1st Embodiment, the code | symbol same as FIG. 1 is attached | subjected and description is abbreviate | omitted. The peripheral information search system in this embodiment also includes a mobile terminal 10 and a peripheral information search system 20. In addition, the mobile terminal 10 and the peripheral information search system 20 are connected to each other via the communication network 30. The contents of the peripheral information search system 20 are the same as those in the first embodiment.

Mobile terminal 10, the information management unit 11a, a communication unit 12, the GPS sensor 13, an acceleration sensor 14, an electronic compass 15, a display device 16, and an operation detection unit 17.

  The operation detection unit 17 detects whether or not the user has operated the mobile terminal 10.

  The information management means 11a is a case where the acceleration sensor 14 recognizes that the user is not moving (that is, the stop state) and the user operates the mobile terminal 10 within a predetermined time. When the operation detection unit 17 detects that it is not, the position information and direction information are transmitted to the peripheral information search system 20 as search conditions. That is, when the operation detection unit 17 does not detect an operation for a predetermined period, the peripheral information search system 20 (more specifically, the information search means 21) indicates that the search range of the direction indicated by the direction information is greater than the other directions. The search range is determined so as to be wide.

  Note that the communication unit 12, the GPS sensor 13, the acceleration sensor 14, the electronic compass 15 and the display device 16 are the same as those in the first embodiment. The information management unit 11a is realized by a CPU of a computer that operates according to a program.

  Next, the operation will be described. FIG. 9 is a flowchart showing an operation example of the mobile terminal 10 in the present embodiment. The operations until the information management unit 11a acquires the position information and the acceleration information and determines whether or not the user is in the stop state are the same as those in steps S71 to S73 in FIG.

  When the user is in a stopped state (“stopped state” in step S73), the information management unit 11a obtains whether or not the user has operated the mobile terminal 10 from the operation detection unit 17, and operates the mobile terminal 10 by the user. Is determined (step S81). If the user has not operated the mobile terminal 10 within a predetermined time (“no operation” in step S81), the information management unit 11a acquires the direction information detected by the electronic compass 15 (step S75), The communication unit 12 is notified of position information and direction information. Then, the communication unit 12 transmits the position information and direction information to the peripheral information search system 20 (step S76).

  On the other hand, when the user has operated the mobile terminal 10 within a predetermined time (“operation” in step S81), the information management unit 11a notifies the communication unit 12 of the location information, and the communication unit 12 The position information is transmitted to the peripheral information search system 20 (step S74).

  Thereafter, the process from receiving the peripheral information from the peripheral information search system 20 to displaying the peripheral information on the display means 16 is the same as steps S77 to S78 in FIG.

  As described above, according to the present embodiment, when the operation detection unit 17 does not detect a predetermined time operation, the position information and the direction information are transmitted as search conditions to the peripheral information search system 20. That is, when it is estimated that there is no operation by the user for a certain time and there is no movement by the acceleration sensor 14 or the like, the direction in which the mobile terminal 10 is currently facing (that is, the direction information acquired by the electronic compass 15 indicates The search range of peripheral information automatically expands in the direction). Therefore, in addition to the effects of the first embodiment, it is possible to perform information retrieval with priority given to user operations.
