Description

  The present invention relates to an information presentation system, an information presentation method, and a program used in the system for presenting information on an object (object) associated with a position to the portable terminal device according to the position and orientation of the portable terminal device. .

  As an example of such an information presentation system, there is a system that presents augmented reality by combining a virtual space with a real space. In this system, an image of a virtual space generated by a server (information presentation device) according to the position and orientation of a mobile terminal device with an imaging function such as a mobile phone with a camera is displayed on a display (display unit) of the mobile terminal device with an imaging function. It can be realized as a display system (see Patent Document 1). As the virtual space image, for example, a virtual object or character information drawn by computer graphics is used.

  These virtual objects and text information are information related to stores, facilities, artificial public objects (roads, bridges, etc.), natural public objects (rivers, lakes, etc.), etc. existing at various positions in the real space, that is, objects associated with the positions By presenting this information, the user can obtain more information than the information obtained from the appearance of the real space image.

  As another example of such an information presentation system, there is a system that displays an image generated by a server (information presentation device) on the display of the portable terminal device according to the position and orientation of the portable terminal device (Patent Document 2). reference).

  However, in the conventional information presentation system, the information presented from the server to the mobile terminal device is related to an object that exists in the direction that the mobile terminal device is facing. Even if the object exists in the vicinity of the terminal device, there is a problem in that information on the object cannot be obtained when the object is present in a direction in which the mobile terminal device is not directed, for example, rearward or laterally. If the orientation of the mobile terminal device is changed, information on objects existing in various directions can be obtained according to the orientation, but the mobile terminal device must be rotated each time, and the operation is troublesome.

  Therefore, it is conceivable to simultaneously present information related to an object that exists not only in the direction in which the mobile terminal device is facing, but also in the direction in which it is not facing. However, simply presenting information about an object that exists in various directions may present unnecessary information.

  The communication unit 22 communicates with the mobile terminal device 4 via the network 1 and the base station 3. The storage unit 23 includes an HDD (hard disk device), and is provided with a position related information DB (database) 231, a direction related information DB 232, and a display information selection table 233.

  The location related information DB 231 includes location related information, such as gasoline stunts, convenience stores, ramen shops, hotels, famous facilities, railway tracks (including subways), major roads, lakes, rivers, coastlines, etc. In addition, information about the object associated with the position in the real space is stored. As shown in FIG. 4A, the position related information includes a position related information ID, a name, position information (latitude, longitude), barycentric position information, content information, and a corresponding direction related information ID. However, the center-of-gravity position information exists only when the object is a polygon (polygon) on the planar map.

  “Position related information ID” is identification information of position related information. “Name” is information indicating the name of the object associated with the position. “Position information (latitude, longitude)” is information indicating the latitude and longitude of the object associated with the position. The “center of gravity position information” is information indicating the position (latitude, longitude) of the center of gravity of the polygon of the target object associated with the position. “Content information” is the content of the object associated with the position, that is, if the object is a store or facility, etc., it is business hours, products, etc. If the object is a section with a railway line, Or a nearby station name.

  The “corresponding direction related information ID” is an ID of the direction related information associated with the object associated with the position. The direction-related information varies depending on whether the object associated with the position is a polygon or a line. In the case of a polygon, information related to an object existing in an arbitrary direction within a predetermined distance from the polygon is direction-related information. For example, if the object associated with the position is Hibiya Park, the information related to Yurakucho Station, Imperial Palace, Kasumigaseki Station, etc. is the direction related information. On the other hand, in the case of a line, information related to an object existing in the extending direction of the line is direction-related information. For example, if the information associated with the location is Yurakucho Station on the Yamanote Line, information on the Shimbashi and Tokyo directions will be relevant information, and if it is Shinagawa Station on the Tokaido Shinkansen, information on the Tokyo and Shin Osaka areas will be displayed.

For example, if the direction-related information is information about Yurakucho Station and the corresponding position-related information is Hibiya Park, Yurakucho Station is located in the northeast of Hibiya Park, so the direction information is “Northeast”.

  The “content information” is the content of the direction-related information, that is, the timetable for Tokyo (inner route), the timetable for Shimbashi (outer route), etc., for Yurakucho Station.

  The “corresponding position related information ID” is an ID of Hibiya Park or the like if the content of the position related information corresponding to the direction related information, that is, the direction related information is information about Yurakucho Station.

  The display information selection table 233 is a table describing rules for selecting the direction related information when the direction related information is provided to the mobile terminal device 4. This rule will be described later.

<Operation of information presentation system>
The schematic operation of the information presentation system having the above configuration will be described with reference to the flowchart shown in FIG. The flow in this figure is performed by the CPU 411 of the mobile terminal device 4 executing the program stored in the ROM 412 and the CPU 211 of the information presentation device 2 executing the program stored in the ROM 212.

  When the user of the mobile terminal device 4 starts an information presentation application (hereinafter referred to as an information presentation application), the mobile terminal device 4 transmits an access request to the information presentation device 2 (step S1). This access request includes the terminal device ID of the mobile terminal device 4.

  Upon receiving the access request, the information presentation device 2 writes the terminal device ID in the RAM 213, and subsequently reads out the image data of the top screen of the information presentation application from the storage unit 23 and transmits it to the portable terminal device 4 (step S11). The image data on the top screen is image data for displaying a message to start the information presentation application. The mobile terminal device 4 receives the image data of the top screen of the information presentation application and displays it on the display unit 43 (step S2).

  Next, in the mobile terminal device 4, the GPS reception unit 44 and the direction detection unit 45 operate under the control of the CPU 411. Thereby, the GPS receiving unit 44 measures (positions) the current position of the mobile terminal device 4 to generate position information and positioning time information, and the direction detection unit 45 indicates the direction in which the mobile terminal device 4 is directed. Information is generated (step S3). The position information and the positioning time information are transmitted to the information presentation device 2 together with the terminal device ID (step S4).

  When the information presentation device 2 receives the position information, the azimuth information, and the terminal device ID (step S12), the information presentation device 2 accesses the position related information DB 231 and a predetermined distance from the current position of the mobile terminal device 4 indicated by the position information received in step S12. Among objects (objects) within (for example, 5 km) and existing at a predetermined angle (for example, 30 ° on both sides) with respect to the direction indicated by the direction information received in step S12, The target object is searched and acquired (step S13). Here, the object to be a line (line object) has a total length of a predetermined length or more, such as a river, a coastline, a main road, or a railway line, and the object to be a polygon (polygon object) is a lake. Compared to other landmark objects such as mountains, theme parks, etc., it is vast.

  Next, the information presentation apparatus 2 determines the direction related information regarding the direction located in a predetermined direction with respect to the object (object) acquired in step S13 based on the rules described in the display information selection table 233. Thus, the area-related information to be presented on the mobile terminal device 4 is acquired (step S14).

  Next, the information presentation device 2 generates image data for displaying the direction-related information acquired in step S14 on the display unit 43 of the portable terminal device 4 in a predetermined display form, and transmits the image data to the portable terminal device 4 (step). S15). The portable terminal device 4 receives this image data and displays it on the display unit 43 (step S5).

  In the portable terminal device 4, steps S3 to S5 are repeated until an operation for ending the information presentation application is detected (step S6: YES), and if detected, an access release request is transmitted to the information presentation device 2 ( Step S7).

  The information presentation device 2 repeats steps S12 to S15 until an access release request is received (step S16: YES), and when received, the access of the mobile terminal device 4 is released (step S17).

<Details of processing for obtaining direction-related information>
The details of the process for obtaining the direction related information and the content of step S14 differ depending on whether the object is a line or a polygon, and will be described below in the order of the polygon and the line.

  FIG. 6 shows processing when the object is a polygon. First, a point closest to the current position of the mobile terminal device 4 on the reference direction line that connects the center of gravity of the object (polygonal object) and the direction associated with the object (polygonal object) is determined. Then, a straight line is drawn from the current position (step S21).

  A specific example of step S21 is shown in FIG. Here, the object (polygonal object) PLG is associated with three directions where the objects α to γ are located. These objects are, for example, stations, temples, mountains and the like. The direction-related information in these three directions is information related to the objects α to γ. Here, a point closest to the current position P0 of the mobile terminal device 4 is obtained on a reference direction line L1 that connects the center of gravity G1 of the object (polygonal object) PLG and the direction in which the object α is located. Draw a straight line L4 from the current position P0 until. The straight line L4 is a perpendicular line drawn from the current position P0 to the reference direction line L1. Although not shown for convenience, the point closest to the current position P0 of the mobile terminal device 4 on the direction reference line L2 connecting the center of gravity G1 and the direction in which the object β is located, the center of gravity G1, and the object γ A point closest to the current position P0 of the mobile terminal device 4 is obtained on the reference direction line L3 connecting the direction where the position is located, and a straight line is drawn from the current position P0 to each point. However, description of the direction reference lines L2 and L3 will be omitted hereinafter.

  Returning to the description of FIG. Next, an angle formed by the direction of the straight line drawn from the current position and the direction in which the mobile terminal device 4 is currently facing is obtained (step S22). In the case of FIG. 7, the direction in which the mobile terminal device 4 is currently facing is the direction of the straight line L5. Therefore, the obtained angle is an angle formed by the direction of the straight line L4 and the direction of the straight line L5.

  Next, the information presentation device 2 presents the information to the mobile terminal device 4 according to the angle obtained in step S22 by referring to the rules for determining the direction-related information described in the display information selection table 233. The direction related information is determined (step S23).

  A rule for determining the direction related information described in the display information selection table 233 will be described with reference to FIG. In this figure, the same reference numerals as those in FIG. The direction D0 is a direction in which the straight line L4 extends from the current position P0, and the directions D1 and D2 are directions extending from the intersection with the straight line L4 to the left side and the right side in the reference direction line L1, respectively. Accordingly, in the case of FIG. 7, the object α is present in the direction located in the direction D1. In this figure, the angle in the clockwise direction with respect to the direction D0 is a positive angle, and the angle in the counterclockwise direction is a negative angle.

  When the current orientation of the mobile terminal device 4 is within a predetermined angle (30 ° in this case) on both sides of the direction D0, the information presentation device 2 provides the direction related information to the mobile terminal device 4 in both directions D1 and D2. Information about the object existing in the location is presented. However, in the case of FIG. 7, since there is no object in the direction located in the direction D2, information regarding the object α existing in the direction located in the direction D1 is presented. For example, when the object (polygonal object) PLG in FIG. 7 is a lake and the object α is a temple, a tag with the name of the lake is displayed on the display unit 43 of the mobile terminal device 4 at the center of the screen. The image data for displaying the tag of the name of the temple is presented. When the tag of the temple name is touched, the details of the temple (such as admission fee, visitable date and time) can be displayed. Also, if the object α is a station, a station name, an up / down timetable, etc. are presented, and if it is a bus stop, a stop name, a destination, a timetable, etc. are presented.

  When the current orientation of the mobile terminal device 4 exceeds −30 ° and is within −120 °, the information presenting device 2 gives the direction related information to the mobile terminal device 4 in the direction D1, that is, the directions D1 and D2. Among them, information about an object existing in a direction located only in a direction close to the current direction of the mobile terminal device 4 is presented. Therefore, in the case of FIG. 7, information on the object α is presented.

  When the current orientation of the mobile terminal device 4 exceeds + 30 ° and is within + 120 °, the information presentation device 2 provides the mobile terminal device 4 with direction D2 as direction-related information, that is, among the directions D1 and D2, The information regarding the target object which exists in the direction located only in the direction close | similar to the present direction of the portable terminal device 4 is shown. In the case of FIG. 7, since there is no object in the direction located in the direction D2, only information related to the object (polygonal object) PLG, that is, position related information is presented to the mobile terminal device 4, and the direction related information is Do not present.

  When the current orientation of the mobile terminal device 4 exceeds −120 ° or + 120 °, the mobile terminal device 4 presents only the position related information regarding the object (polygonal object) PLG, and does not present the direction related information.

  The description regarding the determination of the presentation target information using FIG. 8 relates only to the direction-related information of the direction located in the azimuth direction of the reference direction line L1 in FIG. 7, and is located in the azimuth direction of the reference direction lines L2 and L3. The direction related information of the direction to be selected is also performed in parallel, and the direction related information of the direction located in the direction in which the reference direction lines L2 and L3 extend is presented.

  FIG. 9 shows processing when the object is a line. First, a point closest to the current position of the mobile terminal device 4 is obtained on the object (line object), and a straight line is drawn from the current position (step S31). However, when the object (line object) is a railway line, a straight line may be drawn to the nearest station.

  Next, the angle formed by the direction of the straight line drawn from the current position and the direction in which the mobile terminal device 4 is currently facing is obtained (step S32). Next, by referring to the rules for determining the direction-related information described in the display information selection table 233, the direction-related information to be presented to the mobile terminal device 4 is determined according to the angle obtained in step S32. (Step S33).

  The rules for determining the direction-related information are the same as those in the case where the object is a polygon described with reference to FIG. 8, and the reference direction line L1 in FIG. 8 is regarded as the object (line object). That's fine. If the target (line object) is a road, the direction-related information to be presented is the direction of the vertical line, parking, interchange, etc. If the target (line object) is the coastline, the direction is Enoshima, Manazuru, etc. is there. Moreover, if it is a railroad line, it is the direction of an up-and-down line, a timetable, etc.

  FIG. 10 is a diagram for explaining the direction-related information presented when the object (line object) is a railway line. The illustrated object (line object) is three railway lines composed of a route A, a route B, and a route C. These railway lines are within a circle R1 at a predetermined distance (for example, 5 km) from the current position P1 of the mobile terminal device 4 in step S13 of FIG. 5 and are predetermined on both sides of the direction in which the mobile terminal device 4 is currently facing. Obtained as an object (line object) existing within the range of the angle (for example, 30 °).

  On the routes A and B, the station “I” exists in the circle R1, and on the route C, the stations “RO” and “HA” exist outside the circle R1. Each station is content information of position related information indicating the route A, the route B, and the route C. Stations are generally not polygonal objects, but large stations such as Tokyo Station and Shinjuku Station may be polygonal objects. Moreover, you may comprise so that it may set to the operation mode which presents only the information regarding a railway line by the operation part 42 of the portable terminal device 4. FIG.

  When presenting the direction-related information in the extending direction of these route A, route B, and route C to the mobile terminal device 4, first, the closest point of the route A, route B, route C from the current position P1 of the mobile terminal device 4 Draw a straight line until These straight lines are perpendicular to the route A, route B, and route C from the current position P1. In the figure, since the routes A and B are parallel, the perpendicular line from the current position P1 to the routes A and B becomes a common straight line L11. A perpendicular line dropped on the route C is a straight line L12.

In the drawing, straight lines obtained by rotating the straight line L11 by 30 ° and 120 ° clockwise are L11 ₊₃₀ and L11 ₊₁₂₀ , respectively, and straight lines obtained by rotating the straight line L11 by 30 ° and 120 ° counterclockwise are L11 _-30 and L11 _{-120, respectively.} It was. Further, straight lines obtained by rotating the straight line L12 by 30 ° and 120 ° clockwise are L12 ₊₃₀ and L12 ₊₁₂₀ , respectively, and straight lines obtained by rotating the straight line L12 by 30 ° and 120 ° counterclockwise are L12 _-30 and L12 _-120 , respectively. did.
