Abstract
The present invention relates to an optical position detecting device and method thereof, comprising multiple light emitting components, a driving unit, at least one photo detecting unit, a position storing unit and a position determining unit. Each light emitting components disposed on a plane to form a sensing area respectively projects a light source into the sensing area. The disposing positions of light emitting components and photo detecting unit are recorded in the position determining unit. The driving unit drives light emitting components sequentially. When an object encounters the projected light source above the sensing area, thus sequentially creating a reflected light signal, the photo detecting unit respectively generates sensed signals based on the intensity of the reflected light signal. The position storing unit records the positions of light emitting components and photo detecting unit. The position determining unit determines the position of the object.
