Optical touch apparatus and operating method thereof
An optical touch apparatus including an input interface, at least one sensing module, and a processing module is disclosed. The input interface includes at least one functional input key, and the position of the at least one functional input key disposed on the input interface corresponds to that of the at least one sensing module disposed on the surrounding of the input interface. The at least one sensing module generates a sensing result according to the condition that the at least one sensing module receives sensing lights. The processing module determines touch point position formed on the input interface according to the sensing result.
