    摘要: A sensing device includes a housing and an image sensing system disposed in the housing and used for detecting a reflected light from an object. The image sensing system includes a substrate, a light sensing element, and a reflection and redirection element. The light sensing element is disposed on the substrate. The reflection and redirection element is disposed between the light sensing element and the object, and used for reflecting and redirecting the reflected light from the object to a receiving direction of the light sensing element, such that the light sensing element receives the reflected light and generates a corresponding sensing signal.

    摘要: 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.
