Abstract
An optical touch system is disclosed. The optical touch system comprises a panel apparatus and an optical touch apparatus. The panel apparatus includes a first position and a second position. The optical touch apparatus includes a light emitting module, a light path adjusting module, a light sensing module, and a processing module. The light emitting module and the light sensing module are set on the first position and the second position respectively. The light emitting module emits a sensing light, and the sensing light is reflected by the light path adjusting module to form a reflected light. The light sensing module receives the reflected light and generates a sensing result according to whether the light sensing module receives the reflected light. The processing module determines the touch point position formed on the panel apparatus according to the sensing result.
