<p>An information processing device which can provide a variety of information by a simple construction. In predetermined positions of a region (1), light beacons (2-1 to 2-5) for generating identification numbers respectively as light signals are arranged. A video camera (4) in the region (1) receives a light signal from each light beacon at a sensor unit (5), and determines the position of each light beacon and its own position on the basis of the principle of trigonometrical survey. In the image picked up by the video camera (4), there is shown information corresponding to the detected identification number. The device can be applied to a light beacon and a sensor unit for determining the position of the light beacon contained in the video camera.</p> |
