Computer System And Related Touch Method

摘要

The present disclosure provides a computer system. The computer system comprises a stylus pen and an optical touch system. The stylus pen comprises an optical lens for retrieving relative movement information of the stylus pen when the stylus pen is moving, a first processing unit for analyzing the relative movement information and generating a control signal and a light-emitting unit for sending an optical signal according to the control signal, wherein the optical signal includes the relative movement information. The optical touch system comprises a sensing module for receiving the optical signal and a second processing unit, for calculating relative coordinates of the stylus pen according to the relative movement information included in the optical signal.
