  FIG. 1 is a block diagram of an information providing system 1 in the embodiment. The information providing system 1 projects a video by a video photographing means 2 for photographing a video, a video analyzing means 3 for analyzing the photographed video, a control means 4 for instructing each means based on a result of the analysis, and a video. The display unit 6 can control the transparency and opacity, and the video storage unit 7 stores the projected video data (video information).

  The video photographing means 2 will be described. The image photographing means 2 is a camera using, for example, a CCD or a CMOS and can photograph an image. The camera is arranged to photograph a predetermined place. The photographing may be performed when it is sensed that a user is in a predetermined place by sensing means (not shown). In the case of the information providing system 1, the predetermined place is the front of the display means 5 described below. The shooting range is determined by the performance of the camera, but since there are a plurality of user sizes, the blind spots can be eliminated by using a plurality of video shooting means 2.

  The video analysis means 3 will be described. When the pattern of the video shot by the video shooting device 2 is recognized and a human being is photographed and it is recognized that the human face is reflected, it is determined that the human is in a predetermined position as a user, The eye position is obtained from the image, and the eye position information is transmitted to the control means 4.

  Based on the eye position information sent from the video analysis means 3, the control means 4 calculates the projection position from the eye position and the content of the information to be projected, and sees the content related to the information as the product. The projection unit 5 is controlled so as to project to the projection position that does not obstruct the user's line of sight, the display unit 6 is controlled so as to make the projection position opaque, and the information content projected on the video storage unit 7 is transmitted to the projection unit 5. Control as follows.

  The projection unit 5 will be described. As the projection means 5, for example, a liquid crystal projector is used in which light from a light source, for example, a high-pressure mercury lamp, is generated by a modulation element using liquid crystal and a polarizing plate, and is enlarged and projected by a lens. Further, it is not limited to a liquid crystal projector, and any means that performs the same function may be used.

  The display means 6 will be described. The display means 6 is composed of a member in which a liquid crystal layer is sandwiched between transparent members with transparent electrodes. The transparent electrode is connected to a power source, and a voltage can be applied between the electrodes. When a voltage is applied, the sandwiched liquid crystal elements are aligned in one direction by an electric field. Thereby, the polarized light in a certain direction is easily transmitted. When no voltage is applied, the liquid crystals are uneven and scatter light in various directions. Thereby, the transparency can be controlled. As such a member, for example, a so-called light control glass can be used.

  The video storage means 7 is composed of an HDD or the like, and stores advertisements that advertise products as data. The control means 4 transmits video data to the projection means 5.

  Next, a specific system configuration will be described. The information providing system 1 is a system that provides information to users, and can be combined with a reach-in showcase 8 installed in a convenience store, for example.

  FIG. 2 is a diagram for explaining the reach-in showcase 8. The reach-in showcase 8 is a showcase in which a plurality of shelves 9 are arranged in a showcase installed in a convenience store and the like, and a large number of products 10 such as beer can be displayed. In addition, a transparent door 11 is installed in front of the reach-in showcase 8 so that the user can check the products in the showcase without opening the door 11, and by opening the door 11, the user can select the product 10. Can take.

  FIG. 3 is a diagram for explaining the arrangement of the video photographing means 2. The video photographing means 2 is arranged inside the reach-in showcase 8 and photographs the state of the front surface of the door 11 through the door 11. Further, the photographing unit 2 is arranged at the upper part of the shelf 9 so that the video photographing unit 2 is not easily seen by the user in front of the door 11.

  When there is a user in front of the door 11, the user is photographed by the video photographing means 2, and the video analyzing means 3 identifies that the user is in front of the door 11.

  When the video analysis means 3 identifies that the user is in front of the door 11, the video analysis means 3 sends eye position information to the control means 4. When the user is in front of the door 11 and can recognize his eyes, it can be assumed that the user is looking at the product 10 inside the reach-in showcase 8. The control means 4 takes into consideration the position information of the eyes sent from the video analysis means 3 and the information contents to be displayed by the projection means 5 set in advance, and blocks products related to the information contents from the line of sight. It calculates so that information may be displayed in the position which does not exist, and a projection location is determined like FIG.

  Display means 6 is arranged on door 11, and when display means 6 is in a transparent state, product 10 inside reach-in showcase 9 can be confirmed. The display means 6 can control the transparency for each area. The control unit 4 controls which area the transparency of the display unit 6 is adjusted, and the projection unit 5 controls which area is projected. The projection means 5 projects an image only in the designated area, and projects no image or projects a black display in other areas.

  Further, the control unit 4 can instruct the video storage unit 7 which data among the stored video data is to be transmitted to the projection unit 5.

As a result, a part of the door 11 becomes opaque (light scattering state), and video information is projected onto the part, so that the user can view the video information and the product at the same time.
The analysis unit 3, the control unit 4, and the video storage unit 7 are constituted by a personal computer or the like.

  FIG. 4 is a flowchart showing the operation of the information providing system 1. In S001, the image capturing unit 2 captures an image at a predetermined position. In S002, the video analysis means 3 recognizes the pattern of the video shot by the video recognition device 2, and determines whether or not a person as a user has been shot and the human face is reflected. As a result, if the user's face cannot be recognized, the shooting and determination operations are continued. If the user's face can be recognized, the process proceeds to the next step. In S003, the video analysis means 3 recognizes the position of the user's eyes from the video shot by the video recognition device 2. In S004, the control unit 4 calculates the projection position from the eye position and the content of the information to be projected based on the eye position information sent from the video analysis unit 3. In S005, the control unit 4 operates the projection unit 5 to start projection. In S006, the control unit 4 transmits the projection position to the display unit 5, controls the transparency of the display unit 5 and the transparent position, and transmits the projection position to the projection unit 5 so that only the position to be projected is transmitted. To be projected. In S007, the control unit 4 causes the projection unit 5 to acquire the video content to be projected from the video storage unit 7. In S008, the projection unit 5 projects the video acquired from the video storage unit 7.
