Abstract: An optical touch system includes two touch devices, two optical sensing devices, and a processing module. When the optical touch system is in use according to an optical touch method, the two touch device are used to touch a touch surface and emit first light and second light with different wavelengths respectively. The two optical sensing devices are disposed at the circumference of the touch surface and individually receive the first light and the second light to generate an optical sensing signal. The processing module receives the two optical sensing signals and determines a touch position on the touch surface for each touch device according to the two optical sensing signals. Therefore, the touching by each touch device is independent, so the optical touch system and the optical touch method can allow touch operations for different purposes to be performed simultaneously.
