Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an information display control apparatus 100 according to the first embodiment of the present invention. The information display control device 100 includes a human detection unit 101, a distance calculation unit 102, an information control unit 103, a sensor input interface (not shown) that receives the output of the human sensor group 204 (see FIG. 2), and an information providing device 111. An information input interface (not shown) for reading display information, an information output interface (not shown) for outputting display information to the information display device 104, and a memory (not shown) are provided. For example, the human sensor group 204 is installed adjacent to the information display area 202 at equal intervals as shown in FIG. The information display area 202 is an area where the information display device 104 can display information of an arbitrary size and an arbitrary luminance. Here, the information display area 202 is the floor of the passage 201 in the street or indoors, but it may be installed in an arbitrary space such as a plaza. As for the human sensor group 204, an ordered number is assigned to each human sensor spread as shown in FIG. 3, and X1, X2,..., Y1, Y2,.・ A number is assigned and a unique number such as X1Y1 is assigned to each sensor. The information providing device 111 is a device including a hard disk device, a CD device, or a DVD device that stores display information to be presented to a passerby.

  Next, the operation of the information display control apparatus 100 will be described. The human detection means 101 of the information display control device 100 reads the output of each human sensor of the human sensor group 204 via the sensor input interface and stores it in the memory of the information display control device 100. The human detection means 101 extracts the number of the reacting sensor from the output of the human sensor stored in the memory, and considers that a person or an object exists up to the sensors located around the sensor. For example, if the sensor X3Y2 is reacting, a person or an object including the sensor X3Y2 including the sensor X2Y1, the sensor X3Y1, the sensor X4Y1, the sensor X2Y2, the sensor X3Y2, the sensor X4Y2, the sensor X2Y3, the sensor X3Y3, and the sensor X4Y3 Consider it an existing area. As a result, the area 304 occupied by the person so as to surround the sensor group reacting to the person 203 as shown in FIG. 3 can be calculated. Furthermore, the person detecting means 101 outputs the sensor number (here, “X6Y3”) closest to the information display area 202 in the area 304 occupied by the person.

  Next, upon receiving the sensor number “X6Y3” output from the human detection unit 101, the distance calculation unit 102 calculates the number of sensors from the sensor with the number “X6Y3” to the information display area 202. Here, since the sensor X7Y3 to the sensor X12Y3, the number of sensors is “6”. At this time, since the interval between the sensors is known at the time of installation, it is registered in advance in the memory of the information display control device 100 (here, it is assumed that it is 30 cm at equal intervals). By multiplying the calculated sensor number “6” by the registered sensor interval “30 cm”, a distance 306 “180 cm” between the person 203 and the information display area 202 is calculated and output.

  Upon receiving the distance 306 “180 cm” output from the distance calculation means 102, the information control means 103 selects what to display from the display information stored in the information providing apparatus 111 via the information input interface, and selects this. get. Next, the display size of the display information is determined from the distance 306, and an instruction to display the information on the information display device 104 so as to be the display size is given via the information output interface, and the display information is transmitted. For example, when a person approaches from a position 5 m away, the display information 307 in 2 m square is displayed first, and the display information 307 is always provided in a natural size and easy to see for passers-by by gradually reducing the display size. can do. Further, when the user is far away, the display information 307 is displayed with the brightness increased, and the brightness is decreased as the passerby approaches the information display area 202, so that the passerby first attracts attention and draws attention. When approaching 307 to some extent, it is possible to realize an information display that is easy to view and can browse information for a long time.

The human detection unit 101 and the distance calculation unit 102 obtain an image from a camera installed around the information display area 202, and calculate the distance 306 between the person and the information display area 202 based on the image processing. It may be realized by doing.
As described above, by using this embodiment, it is possible to realize the information display control apparatus 100 that naturally draws attention to a passerby who approaches the information display area from a distance and is easy to see.
As a result, display information can be displayed at a position that naturally enters the passer's field of view, and display information can be displayed in a size that is always easy to see according to the distance. Is also effective as an information display method. In addition, by increasing the brightness of the display information for distant passers-by and making the display information more conspicuous than the surrounding environment, it is possible to obtain an effect of attracting passers-by, which is a leap forward compared to conventional technologies In particular, the recognition rate of information for passersby can be improved, which is very effective.

Functions of the human detection unit 101, the distance calculation unit 102, the human sensor group 204, the information display device 104, and the information providing device 111 are the same as those in the first embodiment. As shown in FIG. 5, the object detection sensor group 507 is a sensor that detects objects such as people and objects that are installed at equal intervals in an information display area 502 that can display information on the information display device 104. It is.

Next, the operation of the information display control device 400 will be described. The human sensor 204, the human detection unit 101, and the distance calculation unit 102 operate in the same manner as in the first embodiment, and the distance calculation unit 102 outputs the distance 506 between the person 203 and the information display area 502. On the other hand, the object detection means 403 reads the output of each object detection sensor of the object detection sensor group 507 via the sensor input interface, calculates the area 508 occupied by a person or an object in the same manner as the person detection means 101, These sensor numbers are stored in the memory of the information display control device 400. In the information display area calculation unit 404, the sensor number stored in the memory by the object detection unit 403 is read, and the detection range of the sensor number other than these numbers is used as the information displayable area 608 (see FIG. 6). Store in memory.
When the information control unit 405 receives the distance 506 from the distance calculation unit 102, the information control unit 405 obtains display information from the information providing apparatus 111 via the information input interface, and can further display information stored in the memory by the information display area calculation unit 404. The area 608 is read out. The information control means 405 changes the display size and brightness of the display information in accordance with the distance 506, and displays the display information at a position where it can be surely seen from the position of the passerby within the information displayable area 608. In addition, the information display device 104 is controlled via the information output interface.

For example, in FIG. 6, a passer-by 203 is on the left side of the passage 201, but there are people and objects 503 on the left side in the information display area 202. Therefore, the information 505 is displayed in the maximum size that can be displayed on the leftmost side in the information display area 502.
As described above, by using this embodiment, attention is naturally paid to a passerby who approaches the information display area from a distance, and information is lost due to the entry of an object such as a person or an object into the information display area. An information display control device 400 that does not occur can be realized.

As a simple example of calculating the traveling direction of the passerby around the information display area, the area occupied by the person is rectangular as shown in FIG. 8, and the traveling direction of the passerby is obtained by using the reaction trajectory of one sensor. There is a way to decide. For example, FIG. 8 shows an example in which the sensors X1Y1 to X5Y5 react at first due to the movement of the passerby 203, but the sensors X7Y3 to X11Y7 react at the next moment. At this time, considering the reaction locus with reference to the leftmost sensor in the region 304 occupied by the person, the movement direction can be easily determined as indicated by an arrow 806 since the sensor X1Y1 moves to X7Y3. Further, the sensor number of the sensor located at the center of the reacting sensor group is transmitted to the information control means 704 as passerby position information.

The information control unit 704 determines the display position so that the center of the display information comes in the traveling direction calculated by the traveling direction calculating unit 703 from the sensor number indicating the center position of the passerby, and the traveling direction is set to the display position.

Similarly to the description in the second embodiment, an object detection sensor group 507 is connected to the information display control apparatus 700, and the information display control apparatus 700 includes an object detection means 403 and an information display area calculation means 404. By performing the same processing as that described in the second embodiment in the information control means 704, it is possible to display information with a size that is easy to see in a state where there is no missing information.

As described above, by using this embodiment, it is possible to realize the information display control device 700 that displays the information in an easy-to-read manner by determining the direction in which the display information is displayed using the traveling direction of the passerby.
As a result, on the streets and indoor passages, information is displayed in front of the direction of travel for passers-by who are heading to the information display area even if the information display location such as a liquid crystal display or screen is not displayed. Since it is displayed and always changes its orientation and size, it is a very effective information display method that can greatly extend the time for displaying information to passers-by compared to conventional methods.
