ABSTRACT:
An information input system inputs pointing information by a slight movement of an input implement held in an operator's hand. The information input system is a combination of an input implement 11 which is manually operated relative to a predetermined reference point to change an attitude thereof, and a detector for optically detecting the attitude of the input implement 11 using light as a detecting medium, in which information according to the manual operation is input to a television set 1 by utilizing the above attitude detection. At the reference point on the television set 1, a light emitting diode 6 is arranged to emit incident light 7 toward the input, implement 11. On the other hand, the detector is provided with an image forming portion, a light-receiving portion and a processing portion, and is integratedly incorporated into the input implement 11 so as to receive the incident light 7 emitted from the light emitting diode 6. The image forming portion converts the incident light 7 emitted from the light emitting diode 6 into a spot image or a pattern image to be projected on the light-receiving portion. The light-receiving portion then outputs electric signals according to positions of the spot image or the pattern image corresponding to the attitude of the input implement 11. The processing portion finally processes the electric signals to extract the attitude of the input implement 11, and transmits the extracted attitude to the television set 1 as input information. This transmission uses modulated infrared-light 10 as a medium.
