When a plurality of targets are set, the target may be switched by an input from the operation unit 23 or at predetermined intervals.

  Next, the operation of the above configuration will be described with reference to the flowchart showing the operation procedure on the server 11 side shown in FIG. Note that the following operation procedure is based on the premise that an application of a ghost game is activated in advance on the mobile device 1 side.

  In the figure, first, in step S1, the control unit 41 determines whether or not the user carrying the mobile device 1 has started the game. When the image recognition unit 34 determines that the image signal captured from the camera 25 is a photograph of a specific silhouette SH drawn in the picture book 2, the image recognition unit 34 sends the picture book 2 to the control unit 41. It is possible to determine that the user has started the game by sending out character shooting information M3 indicating which silhouette SH was shot. That is, here, in order to raise the user's interest in the monster character, authentication is performed using the silhouette SH instead of the office barcode or the two-dimensional code.

  When it is determined that the user has started the game, the process proceeds to the next step S2, and the target position setting means 51 sets the initial position of the target corresponding to the silhouette SH of the monster character selected by the user. The target position information M4 is stored and held in the target position information storage means 55 (step S3).

  In the next step S4, the target position setting means 51 determines whether or not the time measured by the timer means built in the control unit 41 has reached a preset update time. If the time measured by the timer means does not reach the update time, the process proceeds to step S5, and the target / character information creating means 52 reads the target position information M4 from the target position information storage means 55, and the target position information M4. On the basis of the user position information M1 from the user position information creation means 31, the setting position of each target and the direction from the current position of the user to one target are calculated as target information M6. By sending this target information M6 from the server 11 to the display control means 32 of the portable device 1, the display unit 3 of the portable device 1 displays as shown in FIGS.

  In the next step S6, the target arrival determination means 53 determines whether or not the user has reached the target position based on the user position information M1 from the user position information creation means 31, and the user reaches the target position. Only when it is determined that the target has arrived, the target arrival information M5 is sent to the target / character information creating means 52. At this time, unless the target / character information creation means 52 receives the target arrival information M5 from the target arrival determination means 53, the target / character information creation means 52 returns to the above-described step S4, and the time measured by the timer means built in the control unit 41 is set in advance. Until the update time is reached, the target information M6 is repeatedly sent from the server 11 to the display control means 32 of the mobile device 1.

  Eventually, when the time measured by the timer means built in the control unit 41 reaches the preset update time in the procedure of step S4, the procedure returns to the procedure of step S2, and the target position setting means 51 resets the position of each target. In the next step S3, the reset target position is overwritten and updated as new target position information M4 in the target position information storage means 55. Then, after the procedure of step S4, in the next step S5, based on the user position information M1 from the user position information creation means 31 and the new target position information M4, the set position of each target and the current position of the user The target information M6 calculated from the position to the one target is sent from the server 11 to the display control means 32 of the portable device 1.

  As described above, in the procedure from step S2 to step S6, the position of the target can be moved with time.

  In step S6, when the target arrival determination unit 53 determines that the user has reached the target position based on the user position information M1 from the user position information creation unit 31, the process proceeds to step S7. Target arrival information M5 is sent to the target / character information creating means 52. In response to this, the target / character information creating means 52 sends the service additional information M7 to the display control means 32 of the portable device 1 instead of the target information M6. As a result, the display unit 3 displays the AR display 4 of the monster character indicating that the treasure X has been found, the AR display serving as a key or hint for predicting the position of another target, and another user holding the treasure X. An AR display indicating the found state is displayed. At the same time, a hint (key) of the game is displayed on the display unit 3, a virtual photograph can be taken with the AR using the camera of the mobile device 1, and information at the point is added to the service additional information M7. And can be displayed on the display unit 3, or the camera 25 can be used to take a commemorative photo with a character installed at the site.

  In this way, when the user reaches the target position corresponding to the treasure X, the game ends. However, if another silhouette SH is photographed with the camera 25, the ghost game is again performed in the series of steps shown in FIG. Can enjoy. When the user actually finds the treasure X and the treasure X is a seal SL, the acquired seal SL can be pasted on the silhouette SH of the picture book 2 selected in step S1. As a result, it is possible to aim at completion of the picture book 2 while proceeding with the ghost game.
