Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1 FIG.
FIG. 1 shows an example of a configuration including a trajectory display device 10 according to Embodiment 1 of the present invention. The trajectory display device 10 has a configuration as a known computer, and includes a calculation unit that performs processing such as calculation, a storage unit that stores information, an input unit that inputs information, a display unit that displays information, Communication means for performing communication. The arithmetic means includes, for example, a CPU (Central Processing Unit), the storage means includes, for example, a semiconductor memory and a removable storage device, and the input means and the display means include, for example, a touch panel type liquid crystal display.

  The storage means stores information necessary for the operation of the trajectory display device 10 described in this specification. The storage means stores a trajectory display program, and this trajectory display program causes the computer to function as the trajectory display device 10. That is, the computer realizes the function as the trajectory display device 10 by executing the trajectory display program.

  The trajectory display device 10 is a portable computer and can be configured using, for example, a smartphone, a tablet terminal, a mobile phone, or the like. The trajectory display program can be configured by combining, for example, a smartphone OS and an application program. The owner of the trajectory display device 10 carries the trajectory display device 10 during running, for example.

  The trajectory display device 10 has a function of acquiring position information via a GPS (Global Positioning System) 30. The trajectory display device 10 acquires position information of the trajectory display device 10 itself by communicating with the GPS 30, for example.

  The trajectory display device 10 has a function of communicating with the user information server 40 and the position information sharing server 50. Communication is performed, for example, via mobile wireless communication.

  The trajectory display device 10 constitutes a pair with another device (for example, the trajectory display device 20). In the present embodiment, the trajectory display device 20 is a device having the same function as the trajectory display device 10. The owner of the trajectory display device 20 is, for example, a friend of the trajectory display device 10 and carries the trajectory display device 20 as a pair partner when running.

  The process for defining a pair of the trajectory display device 10 and the trajectory display device 20 can be designed as appropriate, but can be performed via the user information server 40 and the position information sharing server 50, for example. More specifically, the user information server 40 may store pair information defining that the trajectory display device 10 and the trajectory display device 20 are a pair, and the position information sharing server 50 stores the trajectory display device 10. The trajectory display device 20 may store a database for sharing position information.

  Hereinafter, the operation of the trajectory display apparatus 10 relating to the trajectory display will be described. The trajectory display device 10 is operable at least in the single trajectory display mode and the multiple trajectory display mode (and may be operable in other modes). The single trajectory display mode is a mode for displaying only the trajectory of the trajectory display device 10 as shown in FIG. 2, and the multiple trajectory display mode is the trajectory and trajectory display of the trajectory display device 10 as shown in FIG. This is a mode for displaying both the trajectories of the device 20 (simultaneously or selectively).

  The operation of the trajectory display device 10 in the single trajectory display mode will be described with reference to FIG. FIG. 2 is an example of a screen displayed by the trajectory display device 10 in the single trajectory display mode. In the single trajectory display mode, the trajectory display device 10 displays the first map image 61 (first map display function). Processing related to acquisition and output of the first map image 61 (including determination of a display range and the like) can be appropriately designed based on the position of the trajectory display device 10 using a known technique.

  Further, the trajectory display device 10 displays the first trajectory 62 (first trajectory display function). The 1st locus | trajectory 62 is a locus | trajectory which concerns on the locus | trajectory display apparatus 10, for example, represents the path | route which the locus | trajectory display apparatus 10 moved to the present time. The first locus 62 is represented by information including time-series data of a set of latitude and longitude, for example. This set may further include altitude.

  The first locus 62 is displayed, for example, superimposed on the first map image 61. The calculation method of the first trajectory 62 can be appropriately designed using a known technique based on the position of the trajectory display device 10. Further, the format, output method, display mode, and the like of the first trajectory 62 can be appropriately designed using known techniques. Information representing the first trajectory 62 is stored in, for example, a storage unit of the trajectory display device 10.

  The trajectory display device 10 may change (move, enlarge, reduce, etc.) the displayed first map image 61 according to the movement of the trajectory display device 10 or the change of the first trajectory 62.

  Information representing the first locus 62 is acquired at any time via the GPS 30, for example. An ordered set of positions at each time can be used as the first trajectory 62. When displaying the 1st locus | trajectory 62, the position in each time can be displayed by the line which connects in order of time, for example. The first trajectory 62 only needs to be displayed at least in part (for example, the portion including the current position). When the first trajectory 62 exceeds the display range of the first map image 61, the first trajectory 62 is displayed. It is not necessary to display the entire 62.

  Next, the operation of the trajectory display device 10 in the multiple trajectory display mode will be described with reference to FIG. FIG. 3 is an example of a screen displayed by the trajectory display device 10 in the multiple trajectory display mode. In the multiple trajectory display mode, the trajectory display device 10 displays the first map image 61 (first map display function) and also displays the first trajectory 62 (first trajectory display), as in the single trajectory display mode. function). In addition to these, the trajectory display device 10 displays the second map image 71 (second map display function) and also displays the second trajectory 72 (second trajectory display function). Further, the displayed second map image 71 may be changed (moved, enlarged, reduced, etc.) in accordance with the movement of the locus display device 20 or the change of the second locus 72.

  The second map image 71 may represent a range that partially overlaps with the first map image 61, or may represent a range that does not overlap with the first map image 61 at all. In addition, when the locus | trajectory display apparatus 10 and the locus | trajectory display apparatus 20 exist in the same point, the 1st map image 61 and the 2nd map image 71 may represent the same range.

  The second trajectory 72 is a trajectory related to the trajectory display device 20, and represents, for example, a route traveled by the trajectory display device 20 up to the current time. The second locus 72 is represented by information including time series data of a set of latitude and longitude, for example. This set may further include altitude.

  The second locus 72 is displayed, for example, superimposed on the second map image 71. The calculation method of the second trajectory 72 can be appropriately designed using a known technique based on the position of the trajectory display device 20. In addition, the format, output method, display mode, and the like of the second locus 72 can be appropriately designed using known techniques. Information representing the second locus 72 is stored, for example, in a storage unit of the locus display device 10. Processing related to the display and storage of the second locus 72 may be designed in the same manner as the first locus 62.

  Information representing the second locus 72 is acquired, for example, via mobile wireless communication. More specifically, for example, the trajectory display device 20 acquires or calculates the second trajectory 72 and transmits it to the location information sharing server 50, and the location information sharing server 50 transfers it to the trajectory display device 10. The second locus 72 can be configured as information in the same format as the first locus 62, for example.

  The second trajectory 72 only needs to be displayed at least in part (for example, the portion including the current position). If the second trajectory 72 exceeds the display range of the second map image 71, the second trajectory 72 is displayed. It is not necessary to display the entire 72.

  In addition, the trajectory display device 10 transmits information representing the first trajectory 62 to the trajectory display device 20. This transmission is performed, for example, via mobile radio communication. More specifically, for example, the trajectory display device 10 acquires or calculates the first trajectory 62 and transmits it to the location information sharing server 50, and the location information sharing server 50 transfers it to the trajectory display device 20.

  As shown in FIG. 2, the second map image 71 and the second locus 72 are not displayed in the single locus display mode. That is, the function of displaying the second map image 71 (second map display function) and the function of displaying the second locus 72 (second locus display function) are stopped.

  The trajectory display device 10 updates information necessary for displaying the trajectory as needed in each mode. For example, in the single trajectory display mode, the position of the trajectory display device 10 itself is periodically acquired via the GPS 30, and the first trajectory 62 is updated. In the multi-trajectory display mode, the first trajectory 62 is similarly updated, the position of the trajectory display device 20 is periodically acquired via the position information sharing server 50, and the second trajectory 72 is updated.

  As described above, when the trajectory display device 10 is operating in the multiple trajectory display mode, both the first trajectory 62 and the second trajectory 72 are displayed. Can know that they are running at the same time, and can share each other's position information and running track in real time. For this reason, even when they are in a place where they cannot directly see each other, they can enjoy running while sharing their senses.

  Furthermore, since the first trajectory 62 and the second trajectory 72 are displayed on the first map image 61 and the second map image 71 that occupy different areas on the screen, the trajectories of two runners in separate locations can be simultaneously displayed. Can be displayed. In addition, in order to display the locus | trajectory of two runners in the separated place using the same map image, a large scale map is required, and a locus | trajectory becomes difficult to read, but this embodiment shows in FIG. As described above, since independent map images are used, the scale of each map can be reduced (that is, the displayed map can be enlarged), and the locus can be easily read.

  Other information may be displayed on the screen of the trajectory display device 10. For example, in the example of FIG. 2, the user name (“jun”) representing the owner of the trajectory display device 10, the icon or photograph representing the owner of the trajectory display device 10, the length of the first trajectory 62, that is, the previous travel The distance (“km 0.12”), the recording time of the first trajectory 62, that is, the travel time so far (“time 1:23:45”), and the like are displayed. In addition, in the example of FIG. 3, in addition to these, a user name (“natsuko”) representing a pair partner (the owner of the locus display device 20), an icon or photograph representing the pair partner, the length of the second locus 72, that is, this The travel distance up to, the recording time of the second locus 72, that is, the travel time so far, and the like are displayed.

  In addition, a means for inputting an instruction operation to the trajectory display device 10 may be displayed. For example, in FIG. 2 and FIG. 3, a tracking end button 63 is displayed. It should be noted that the image representing the tracking end button 63 may be different depending on the mode as shown.

  FIG. 4 is a flowchart for explaining the flow of processing of the trajectory display apparatus 10 including control of these modes and the like. The process of FIG. 4 is started in response to the locus display device 10 receiving a predetermined tracking start operation in a state where the locus display device 10 and the locus display device 20 are paired (step S1).

  The specific content of the tracking start operation can be designed as appropriate. For example, it may be an operation for starting a specific application, and by starting the specific application, tapping the tracking start button displayed. There may be. The tracking start button may be displayed, for example, in the same position as the tracking end button in FIGS. 2 and 3 in a manner different from the tracking end button. The owner of the trajectory display device 10 performs this tracking start operation when starting running, for example.

  The trajectory display device 10 transmits a tracking start signal in response to the tracking start operation (step S2). The tracking start signal is transmitted to the trajectory display device 20. More precisely, the tracking start signal is transmitted from the trajectory display device 10 to the user information server 40, and further transmitted from the user information server 40 to the trajectory display device 20. This tracking start signal is a signal for notifying that the trajectory display device 10 starts its own tracking. The tracking start signal is transmitted to the trajectory display device 20 via the user information server 40, for example.

  Further, the trajectory display device 10 initializes a trajectory (first trajectory) related to the trajectory display device 10 in response to the tracking start operation (step S3). For example, the position information of the trajectory display device 10 itself is acquired from the GPS 30, and the starting point of the trajectory is stored as the position.

  Thereafter, the trajectory display device 10 starts an operation in the single trajectory display mode (step S4). As a result, for example, a screen as shown in FIG. 2 is displayed.

  The trajectory display device 10 can receive a tracking start signal from the trajectory display device 20 in the single trajectory display mode (step S5). This tracking start signal is a signal for notifying the trajectory display device 10 that the trajectory display device 20 starts its own tracking. For example, the signal is transmitted from the trajectory display device 10 to the trajectory display device 20 in step S2. It is configured in the same format.

  Although not shown in FIG. 4, the trajectory display device 20 transmits this tracking start signal in response to, for example, the tracking start operation as described above. For example, when the pair partner performs a tracking start operation when starting running, a tracking start signal is transmitted from the track display device 20 to the track display device 10 accordingly.

  In response to receiving the tracking start signal, the trajectory display device 10 initializes the second trajectory 72 related to the trajectory display device 20 (step S6). For example, the locus of the locus display device 20 is set to an undefined state.

  Further, the trajectory display device 10 starts the operation in the multiple trajectory display mode in response to receiving the tracking start signal (step S7). That is, the trajectory display device 10 switches the operation mode from the single trajectory display mode to the multiple trajectory display mode. As a result, for example, a screen as shown in FIG. 3 is displayed.

  The trajectory display device 10 can receive a tracking end signal from the trajectory display device 20 in the multiple trajectory display mode (step S8). This tracking end signal is a signal for notifying the trajectory display device 10 that the trajectory display device 20 ends its own tracking.

  In response to receiving the tracking end signal, the trajectory display device 10 starts the operation in the single trajectory display mode (step S9). That is, the trajectory display device 10 switches the operation mode from the multiple trajectory display mode to the single trajectory display mode. Thereby, the display content of the trajectory display device 10 is switched from the format of FIG. 3 to the format of FIG. 2, and the second map image 71 and the second trajectory 72 that have been displayed until then are not displayed. The trajectory display device 10 may end the update of the second trajectory 72 in response to receiving the tracking end signal.

  The trajectory display device 10 can accept a predetermined tracking end operation in the single trajectory display mode (step S10). The specific content of the tracking end operation can be designed as appropriate. For example, it may be an operation for ending the execution of a specific application, or by tapping the tracking end button displayed in the single trajectory display mode. There may be. The owner of the trajectory display device 10 performs this tracking end operation, for example, when the running is ended.

  The trajectory display device 10 may end processing such as display of the first map image 61, display of the first trajectory 62, and update of the first trajectory 62 in accordance with the tracking end operation.

  The trajectory display device 10 transmits a tracking end signal in response to the tracking end operation (step S11). In this example, the tracking end signal is transmitted to the user information server 40. This tracking end signal is a signal for notifying that the trajectory display device 10 ends its own tracking. In this example, the trajectory display device 10 operates in the single trajectory display mode. However, when the trajectory display device 10 operates in the multiple trajectory display mode, the tracking end signal is further transmitted to the user information server 40. To the trajectory display device 20.

  Thereafter, the trajectory display device 10 ends the process shown in FIG. For example, the execution of a specific application that has been executed may be terminated. Alternatively, the process may be returned to step S1 to enter a state of waiting for a tracking start operation.

  In addition, the specific process in case the locus | trajectory display apparatus 20 transmits a tracking end signal in step S8 may be the same as the process which starts tracking end operation with respect to the locus | trajectory display apparatus 10 in step S11, for example.

  5 to 7 are sequence diagrams showing an example of the flow of processing by the trajectory display device 10, the trajectory display device 20, the user information server 40, and the position information sharing server 50 that operate as described above. In particular, FIG. 5 is a sequence diagram illustrating an example of processing for defining a pair, FIG. 6 is a sequence diagram corresponding to an execution example of steps S1 to S7 in FIG. 4, and FIG. It is a sequence diagram corresponding to the example of execution of the part of step S8-S11 of FIG. 6 and 7 roughly show the correspondence with each step in FIG.

  As described above, according to the trajectory display device 10 according to the first embodiment of the present invention, two trajectories are displayed on two maps as shown in FIG. The trajectory of a human runner can be displayed at the same time.

  Further, in the first embodiment, since the trajectory display device 10 automatically performs switching between the single trajectory display mode and the multiple trajectory display mode in response to reception of the tracking start signal and the tracking end signal, the user performs a switching operation. There is no need to do this, and the mode can be switched seamlessly.

In the first embodiment, the following modifications can be made.
In the multiple trajectory display mode, it is not necessary to display two maps simultaneously. For example, the trajectory display device 10 has a function of selectively displaying a screen (first screen) including the first map image 61 and a screen (second screen) including the second map image 71 in the multiple trajectory display mode. May be provided. The screen selection operation and screen selection processing for switching between the first screen and the second screen can be designed as appropriate. For example, an operation of tapping a predetermined screen switching button, an operation of sliding the screen, an operation of flicking the screen, It may be configured to switch the screen according to the above. Further, when the screen is switched, the first screen and the second screen may be displayed side by side and slid in the horizontal direction. Further, information indicating whether the trajectory display device 10 is operating in the single trajectory display mode or in the multiple trajectory display mode may be displayed.

  Even when two maps are displayed simultaneously, the display mode of the map is not limited to that shown in FIG. In FIG. 3, the first map image 61 and the second map image 71 are displayed side by side on the left and right, but may be displayed side by side on the top and bottom, or may be displayed according to other positional relationships.

  The reception of the tracking start signal (step S5) may be executable before the tracking start operation (step S1). If the tracking start signal has been received first, the trajectory display device 10 may start the operation in the multiple trajectory display mode in response to the tracking start operation (ie, the process proceeds from step S1 to step S7). Also good). Alternatively, the trajectory display device 10 may operate in a specific mode that displays the second map image 71 and the second trajectory 72 without displaying the first map image 61 and the first trajectory 62.

  The tracking end operation (step S10) may be acceptable in the multiple trajectory display mode. If a tracking end operation is accepted in the multiple locus display mode, the process may proceed to step S11.

  In the first embodiment, the trajectory display device 10 and the trajectory display device 20 have the same function. When the trajectory display device 20 operates in the multiple trajectory display mode, the trajectory display device 10 is viewed from the trajectory display device 20. Corresponds to “other devices”. As a modification, the trajectory display device 20 may not have the same function as the trajectory display device 10, or may have an additional function. For example, one of the functions of the user information server 40 and the location information sharing server 50 may be provided and function as a host machine. In that case, the other may function as a guest machine. For example, even in the case where the trajectory display device 20 does not perform screen display relating to the trajectory, in principle, the same effect as in the first embodiment can be obtained for the user on the trajectory display device 10 side.

  Although the maximum number of trajectories displayed at the same time in the first embodiment is two, the trajectory display device 10 may be operable in a mode in which three or more trajectories are displayed using three or more map images. . In that case, the trajectory display device 10, the trajectory display device 20, and another trajectory display device form a group for transmitting and receiving a tracking start signal, a tracking end signal, information representing the trajectory, and the like. May be.

  Specific processing for forming a pair of the trajectory display device 10 and the trajectory display device 20 can be appropriately designed, but may be performed via an SNS (social networking service). For example, the owner of the trajectory display device 10 executes a specific application program, specifies an SNS interface, and transmits an invitation message to the pair partner. A pair partner is formed by operating the trajectory display device 20 to receive this message and performing an operation to approve it.
