Position Detecting System and Position Detecting Method

摘要

A position detecting system includes an indicating device including a photodiode that detects timing of a light pulse and a transmission unit that transmits a signal representing the timing, a plurality of light sources that emit light pulses to areas acquired by dividing a screen into a plurality of parts at timings unique to the light sources, a reception unit that receives the signal representing the timing, and a control unit that detects a position of the indicating device based on the signal representing the timing.
