Optical touch sensing system, optical touch sensing device and touch detection method thereof
An optical touch sensing system, an optical touch sensing device, and a touch detection method thereof are provided. The optical touch sensing system includes an optical touch sensing device and a stylus. The optical touch sensing device includes a touch panel, multiple optical sensors, a first light source, and a processor. The touch panel has a touch surface. The first light source generates a first light periodically. The stylus includes a switch module and a second light source. The switch module enables the second light source to generate a second light when the stylus touches the touch surface. The processor determines a position touched by the stylus according to the first light and the second light received by the optical sensors.
