Abstract: A touch system with track detecting function includes a touch pad for sequentially sensing a plurality of positions of an indication object at a plurality of moments in order to detect a track of the indication object on the touch pad, and a processor for continuously generating motion vectors according to the track of the indication object on the touch pad, for generating a candidate motion vector according to at least one motion vector, and for nonlinearly generating a target motion vector according to the candidate motion vector in order to move a target shown on a display panel. Each of the motion vectors represents a difference between a position of the indication object and a next position of the indication object.

Abstract: There is provided a pupil tracking device including an active light source, an image sensor and a processing unit. The active light source emits light toward an eyeball alternatively in a first brightness value and a second brightness value. The image sensor captures a first brightness image corresponding to the first brightness value and a second brightness image corresponding to the second brightness value. The processing unit identifies a brightest region at corresponding positions of the first brightness image and the second brightness image as an active light image.
