Abstract:
A remote coordinate input system for use with a screen, comprising:a designator including a first surface on which at least three first reflecting elements are arranged in a plane, and a second reflecting element arranged on an orthogonal axis to the plane, said second reflecting element arranged on a second surface different from said first surface; an imaging device that images relative positional relationship between the first reflecting elements and the second reflecting element; an irradiating device that irradiates the at least three first reflecting elements and the second reflecting element; a coordinate converter that obtains an orientation of the designator with respect to said imaging device from an image that is imaged by said imaging device and converts the image into planar coordinates; an output device that outputs the planar coordinates that are obtained by the coordinate converter; and a display that displays designation information on the screen based on the planar coordinates that are obtained from said output device.
