An electronic device includes a housing, an optical touch module, and a detecting unit. The housing includes a first body and a second body, and an angle is formed between the first body and the second body. The optical touch module executes a positioning function by sensing signals. The detecting unit is configured to the optical touch module, and is used for detecting the angle. When the angle is smaller than a predetermined angle, the detecting unit instructs the optical touch module to pause executing the positioning function, so as to avoid false position determinations by the optical touch module.
