FIG. 3 is a flowchart illustrating a procedure of output control performed by the content output apparatus. 4 to 6 and FIGS. 7A and 7B are diagrams showing examples of output control methods.

  In the information distribution method according to the first embodiment, when content is output from the content output device 3 to the display device 2, first, as shown in FIG. 3, the video analysis unit 303 first captures the image taken by the camera 7. The previous image of the display device 2 is acquired and analyzed (step 901), and it is determined whether or not a change is detected (step 902). The step 901 compares, for example, the latest frame on the acquired video with a video (frame) taken when there is no viewer in front of the display device 2 or a video (frame) before Δt seconds. Analyzing the presence or absence of changed areas. If it is determined in step 902 that there is no changed area, the process returns to step 901 and video analysis is continued.

  When it is determined in step 902 that there is a changed area, the video analysis unit 303 notifies the event generation unit 304 of the content of the change, for example. At this time, the event generating means 304 generates an event corresponding to the content of the change (step 903). Then, the event generation unit 304 notifies the script execution unit 305 of the event generated in the step 903.

  When the script execution unit 305 is notified of the event, the script execution unit 305 acquires a script corresponding to the event from the action script storage unit 307, for example (step 904), and executes the script (step 904). 905). At this time, the script execution unit 305, for example, passes a control command to the screen control unit 306, and causes the screen control unit 306 to output the content to the display device 2, or the content being output as content of detailed information. The process of switching to is executed. When the script is executed, as shown in FIG. 3, the process returns to the step 901 and the video analysis is continued.

  In the output control of the content performed in such a procedure, in step 901, for example, as shown in FIG. 4, a person (viewable person) 10 in front of the display device 2 stands for a predetermined time. When it is detected that there has been a change in staying at the same position, control is performed to output (display) the contents 801, 802, and 803 on the display device 2. At this time, in step 903, an event corresponding to the case where a certain person 10 stays at the same position for a certain time is generated. In step 904 and step 905, a script corresponding to the event is acquired and executed. At this time, the script executed in step 905 may be an instruction that causes the screen control unit 306 to read the contents 801, 802, and 803 from the content holding unit 302 and display them on the display device 2 in a pop-up manner.

  Further, in step 901, for example, as shown in FIG. 5, a change has been detected in which the viewer 10 standing in the vicinity of the content 801A with the display device 2 has moved near the other content 803A. In this case, it is also possible to control to switch the content 803A displayed near the position where the moved viewer 10 is present to the content 803B including the detailed information. At this time, in step 903, an event corresponding to the case where the viewer is moved before a certain content is generated. In step 904 and step 905, a script corresponding to the event is acquired and executed. At this time, the script executed in the step 905 reads the content 803B including the detailed information of the content 803A in front of the viewer 10 from the content holding unit 302 into the screen control unit 306, and the display device The command may be output to 2 and the content is switched.

  At this time, for example, as shown in FIG. 6, a map in the vicinity of the installation location is displayed on the display device 2 as a background, and for example, the viewer 10 stops in front of the display device 2. Sometimes, the display device 2 may display contents 801A, 802A, 803A, 804A, 805A. Then, when the viewable viewer 10 stopped in front of the display device 2 moves, the content 804A in front of or near the moved destination may be switched to the content 804B including detailed information.

  In addition, for example, as shown in FIG. 7A, when the viewer 10 stops in front of the display device 2, the content 801A is only in the vicinity of the position where the viewer 10 is present. , 802B may be controlled (output). Furthermore, not only the operation in which the viewer 10 stops or moves, but the viewer 10 places a finger on the content displayed on the display device 2 as shown in FIG. 7B, for example. Control may be performed so that the content pointed by the finger is switched to the content 802B including the detailed information when the operation is performed.

  As described above, according to the information distribution method of the first embodiment, when a viewer who has viewed the content displayed on the display device 2 desires more detailed information or related information about the content, The image 8P displayed on the content 8 may be read using the communication terminal 5, and the address information of the acquisition destination of the detailed information and related information may be extracted from the read image 8P. Therefore, when obtaining the related information, it is possible to reduce the burden of searching for the information of the obtaining source and the burden of inputting the address of the obtaining destination while the viewer is viewing the content. In addition, since the address information is extracted from the image 8P, it is possible to prevent the related information from being obtained due to an input error.
