By executing, it functions as various function realization means. The server device 10 may be configured by a single information processing device or may be configured by a plurality of information processing devices dispersed on a network.

[2. Terminal device hardware configuration]
FIG. 2 is a block diagram showing an outline of a hardware configuration of the portable terminal 20 which is a terminal device. As shown in FIG. 2, the portable terminal 20 mainly includes a control unit 21, a communication unit 22, a storage unit 23, an operation unit 24, a display unit 25 and a positioning unit 26. The control unit 21 mainly includes a CPU 21 a and a memory 21 b. The description of each configuration will be described later. The portable terminal 20 functions as various function realizing means, for example, by the CPU 21a executing a predetermined program stored in the memory 21b or the like.

  The control unit 21 controls the operation of various components of the mobile terminal 20 and controls the execution of various processing. Details of the process executed by the control unit 21 will be described later. The communication unit 22 is a communication interface for communicating with another external device.

  The storage unit 23 is configured of a storage device such as a hard disk. The storage unit 23 stores various programs and various information necessary for execution of processing in each information processing apparatus. The operation unit 24 is a user interface for receiving an operation instruction from a user.

  The positioning unit 26 specifies the position (for example, latitude, longitude) of the portable terminal 20 based on the signals received from the GPS satellites 30, 31, 32 and communication devices (for example, the base station 40 and the routers 41 and 42) A process of specifying the date and time when the position is specified (that is, specifying positioning information) is performed. The positioning unit 26 outputs the identified positioning information. Note that information detected by various sensors (not shown) such as a gyro sensor, a geomagnetic sensor, an acceleration sensor, and an atmospheric pressure sensor included in the portable terminal 20 is used together with signals from the GPS satellites 30, 31, 32 and the like to carry Positioning information of the terminal 20 can be identified.

[3. Software Configuration of Terminal Device]
The portable terminal 20 mainly includes a database 210, a traveling direction identification unit 220, a moving speed measurement unit 230, a display control unit 240, and a positioning accuracy determination unit 250 as software configurations (functional configurations).

  The database 210 stores various types of information such as information necessary for processing executed in the portable terminal 20 and information generated by the processing.

  The traveling direction identification unit 220 identifies the traveling direction with respect to the movement of the user of the mobile terminal 20 based on the positioning information (the positioning position and the positioning time) of the mobile terminal 20. For example, the traveling direction identification unit 220 acquires, from the positioning unit 26, information on the positioning position at predetermined time intervals (for example, every one second), and the direction of the line connecting the positioning positions in order of passage of positioning time. The movement direction of the user of the portable terminal 20 is specified based on The traveling direction may be identified based on the orientations of a plurality of lines connecting the positioning positions.

  An example of a method of specifying the traveling direction by the traveling direction specifying unit 220 will be described with reference to FIG. 4. In FIG. 4, five positioning positions of the mobile terminal 20 are indicated by circles, and the positioning positions are connected by an arrow that points in the direction in which the positioning time passes in the order in which the positioning time passes. The traveling direction identification unit 220 identifies the traveling direction of the movement of the user corresponding to the five positioning positions, based on the directions and lengths of the four arrows connecting the positioning positions. For example, the traveling direction identification unit 220 can specify the traveling direction based on the average value of the values weighted by the lengths of the arrows with respect to the directions of the four arrows connecting the positioning positions. Also, in this example, the traveling direction is specified using five positioning positions, but the invention is not limited thereto, and the traveling direction is determined using any number of positioning positions (for example, two or ten). It can be identified.

  In FIG. 4, although the actual traveling direction is straight, the line connecting the five positioning positions is not a straight line. This is because an error may occur between the measured position of the mobile terminal 20 and the actual position with a size corresponding to the positioning accuracy.

  The moving speed measurement unit 230 measures the moving speed of the user of the portable terminal 20 based on the positioning information (positioning position and positioning time) of the portable terminal 20. Specifically, the moving speed measurement unit 230 acquires information on the positioning position at predetermined time intervals (for example, every one second) from the positioning unit 26, and continues between the positioning positions in the order in which the positioning time passes. The movement speed of the movement of the user of the portable terminal 20 is measured based on the distance and the difference in positioning time.

  An example of a method of measuring the moving speed by the moving speed measurement unit 230 will be described with reference to FIG. 4. The moving speed measurement unit 230 specifies the distance between two positioning positions connected by an arrow and the difference between the positioning times of the positioning positions, and the difference between the distance between the specified positioning positions and the positioning time Based on, measure the moving speed of the user.

  The display control unit 240 performs control for causing the display unit 25 to display various types of information. For example, the display control unit 240 displays the map image acquired from the server device 10 (or from the storage unit 23) on the display unit 25, and the positioning position of the portable terminal 20 specified by the positioning unit 26 on the map image. It can indicate the current location of the user based on.

  The display control unit 240 can further control to change the display on the display unit 25 based on the traveling direction of the movement of the user of the portable terminal 20 specified by the traveling direction specifying unit 220.

  For example, the display control unit 240 can control to display the map (that is, display with head-up) such that the traveling direction of the user on the map is upward. That is, the display control unit 240 can rotate the map and cause the display unit 25 to display the map according to the traveling direction of the user based on the positioning information of the portable terminal 20.

  In addition, the display control unit 240 can display an image (a direction display image) having a shape indicating the traveling direction of the user. In addition, when the direction display image is displayed, the display of the map may be a head-up display or a display in which a predetermined direction is upward (for example, a north-up display). Further, the display position of the direction display image may be displayed at a position corresponding to the user's current position on the map, or separately from the image showing the current position (ie, at a position unrelated to the current position). May be displayed.

  An example of the direction display image will be described with reference to FIG. (A) to (f) of FIG. 6 show an example of a direction display image, and the upper direction of each image is a direction indicating the traveling direction. Note that these drawings are merely examples of direction display images, and any image that can indicate a direction can be a direction display image.

  The display control unit 240 can further control to change the display on the display unit 25 based on the moving speed of the user measured by the moving speed measurement unit 230. For example, when the moving speed of the user measured by the moving speed measurement unit 230 is equal to or less than a predetermined value (rotation stop threshold), the display control unit 240 causes the display unit 25 to display the display so as to stop the rotation of the map. Can be controlled.

  With reference to FIG. 5, when the moving speed of the user measured by the moving speed measurement unit 230 is equal to or less than the rotation stop threshold value, the meaning of stopping the rotation of the above-described map will be described. FIG. 5 shows five positioning positions of the mobile terminal 20 when the user carrying the mobile terminal 20 is moving slowly (for example, 2 km / h), and each positioning position is In the order in which positioning time passes, it is connected by the arrow which turns to the direction where positioning time passes.

  As described above, an error may occur between the measured position of the mobile terminal 20 and the actual position with a size corresponding to the positioning accuracy. Therefore, when the user's traveling direction is specified using the positioning position where such an error may occur, a direction different from the actual traveling direction may be specified. The gap between the identified traveling direction and the actual traveling direction is the lower the moving speed of the user (specifically, the moving distance of the user in the period for specifying the traveling direction is the degree of the positioning error It is considered that the shorter the The example in FIG. 5 indicates that when the user is moving slowly, the traveling direction of the user identified by the traveling direction identification unit 220 points in a direction different from the actual traveling direction.

  The above-mentioned rotation stop threshold is a value of speed (for example, such as not to cause a shift between the traveling direction specified by the traveling direction identification unit 220 and the actual traveling direction) or to decrease even if a shift occurs. 2 km / h) is set. The rotation stop threshold may be set to a value corresponding to the moving means of the user. For example, when traveling by car, the rotation stop threshold may be set at 10 km / h, and when traveling by foot, the rotation stop threshold may be set at 2 km / h. The determination of the moving means of the user can be made by any method. In the present embodiment, it is assumed that the method is performed by a known method, and the description is omitted here. A threshold (for example, a direction display threshold and a movement stop threshold) to be described later may be set to a value according to the moving means of the user.

  As described above, according to this embodiment, the rotation stop threshold is set, and when the moving speed of the user measured by the moving speed measurement unit 230 is equal to or less than the rotation stop threshold, the rotation of the map is stopped. As a result, it is possible to prevent the user from being confused by the map being rotated according to the traveling direction different from the actual one specified by the traveling direction specifying unit 220. Thereby, the fall of the convenience of the portable terminal 20 for a user can be prevented.

  In addition, when the moving speed of the user measured by the moving speed measurement unit 230 is equal to or higher than a predetermined value (direction display threshold), the display control unit 240 displays an image having a shape indicating the moving direction of the user (the above-described direction display It is possible to display the image and control not to display the direction display image if it is less than the direction display threshold. Note that the direction display threshold value has a low speed (for example, a value that does not cause a gap between the traveling direction specified by the traveling direction identification unit 220 and the actual traveling direction) or decreases even if a gap occurs (for example, , 2 km / h) is set.

  The display control unit 240 may change and display the shape of the direction display image according to the value of the moving speed. For example, when the movement speed is equal to or higher than the direction display threshold, the display control unit 240 displays the direction display image of any of (a), (b), and (c) in FIG. 6 (d), (e), or (f) may be displayed (e.g., the image of (a) being displayed, the moving speed When it falls below, it may be changed to the image of (d) and displayed. As a method of changing and displaying the shape of the direction display image, when the moving speed is within a predetermined range less than the direction display threshold, the display control unit 240 is more than the direction display image when the moving speed is equal to or higher than the direction display threshold. The direction display image can be displayed in a shape indicating the traveling direction of the user in a wide angle range (for example, the displayed image of (b) can be changed to the image of (e) and displayed) ).

  Furthermore, the display control unit 240 can display an image of another shape (for example, the image of (e) displayed) when the moving speed falls below a predetermined threshold that is lower than the direction display threshold (for example, the image The image is changed to the image of (g) and displayed, or the image of (f) that has been displayed is changed to the image of (h) and the like).

  The display control unit 240 can control not to display the direction display image when the moving speed is less than the direction display threshold.

  As described above, according to the present embodiment, when the moving speed is low (when it is less than the direction display threshold), the display control unit 240 displays the direction display image having a shape indicating the traveling direction of the user in a wide angle range. Display or do not display direction display image. As a result, it is possible to prevent the user from being confused by the direction display image indicating a traveling direction different from the actual one specified by the traveling direction specifying unit 220. Thereby, the fall of the convenience of the user of the portable terminal 20 can be prevented.

  Furthermore, the display control unit 240 controls to display a current position image indicating the current position of the user at a position on the map corresponding to the current position of the user specified based on the positioning information of the portable terminal 20. The current image is displayed to move on the map in accordance with positioning information that changes according to the movement of the user.

  In addition, the display control unit 240 controls to stop the movement of the current location image on the map when the movement speed of the user measured by the movement speed measurement unit 230 is equal to or less than a predetermined value (movement stop threshold). Can. That is, the display control unit 240 displays the current location image at the position displayed when the moving speed becomes equal to or less than the moving stop threshold, and does not move from the position until the moving speed exceeds the moving stop threshold. Images can be displayed. When the movement speed exceeds the movement stop threshold, the current location image is displayed to move the position on the map corresponding to the current location.

  In addition, it is preferable that the value (for example, 2 km / h) of low speed is set as a movement stop threshold value. By setting the movement stop threshold in this manner, display on the display unit 25 is performed as if the user is moving due to the positioning accuracy although the user is not moving. Can prevent the user from being confused.

  For example, an image as shown in FIG. 6 can be used as the current position image. In addition, since the image of (a)-(f) of FIG. 6 can show a user's advancing direction, by displaying these images on the user's present location on a map, as a direction display image and a present location image It can be used.

  It returns to the explanation of FIG. The positioning accuracy determination unit 250 determines the accuracy of the positioning performed by the positioning unit 26 (the accuracy of the positioning information identified by the positioning unit 26). The determination method of the positioning accuracy can be performed by any method. For example, it is determined that the accuracy of the positioning performed based on the signals received by the portable terminal 20 from the GPS satellite 30, the base station 40, or the router 41 is higher as the intensity of the signals received is higher. It can be determined to be low. The positioning accuracy determination unit 250 can output the determination result of the positioning accuracy by any method. For example, the positioning accuracy determination unit 250 can output the determination result of the positioning accuracy at five or ten levels.

  The determination result of the positioning accuracy determined by the positioning accuracy determination unit 250 can be used to determine the above-described threshold (for example, the rotation stop threshold, the direction display threshold, the movement stop threshold). That is, different values can be set as the threshold according to the determination result of the accuracy. For example, the threshold may be set to be a lower value as the determined positioning accuracy is higher. That is, since the deviation between the positioning position and the actual position of the portable terminal 20 is smaller as the positioning accuracy is higher, the threshold used for the above processing can be set to a lower value.

  Next, a flow of an example of processing executed in the mobile terminal 20 will be described with reference to FIG. Note that each processing step included in the processing flow described below can be arbitrarily changed in order or can be executed in parallel, as long as no contradiction occurs in the processing content. You may add steps. In addition, while the steps described as one step can be divided into a plurality of steps and executed for convenience, those described into a plurality of steps for convenience can be grasped as one step. The details of the processing of each processing step are omitted here because they have already been described.

  First, in step S11, the control unit 21 measures the moving speed of the user of the mobile terminal 20 based on the positioning information (positioning position and positioning time) of the mobile terminal 20.

  In step S12, the control unit 21 determines whether the moving speed measured in step S11 is equal to or less than the rotation stop threshold value. If it is less than the rotation stop threshold (S12: Yes), the process proceeds to step S15, and if it is not less than the rotation stop threshold (S12: No), the process proceeds to step S13.

  In step S <b> 13, the control unit 21 specifies the traveling direction of the movement of the user of the mobile terminal 20 based on the positioning information of the mobile terminal 20.

  In step S14, the control unit 21 rotates the map according to the moving direction of the user specified in step S13, and causes the display unit 25 to display (for example, with head-up).

  In step S15, when the map is rotated and displayed on the display unit 25 in accordance with the traveling direction of the user, the control unit 21 stops the rotation.

  In step S16, the control unit 21 determines whether to end the display on the display unit 25. If not (S16: No), the process proceeds to step S11, and if it is ended (S16: Yes) , And end the process shown in FIG.

  As described above, according to the present embodiment, the rotation stop threshold is set, and when the moving speed of the user measured based on the positioning information is equal to or less than the rotation stop threshold, the rotation of the map is stopped. As a result, the map is rotated according to a direction of travel different from the actual direction specified based on the positioning information, and the user is not confused. Thereby, the fall of the convenience of the user of the portable terminal 20 can be prevented.

  The present invention is not limited to the embodiments described above, and can be implemented in other various forms without departing from the scope of the present invention. The above embodiments are merely illustrative in every respect and are not to be construed as limiting.
