Abstract
An electronic apparatus includes a structure and an optical navigation circuit. A first end of the structure is located inside the electronic apparatus and its second end corresponds to a user's control. The structure can be moved forward/backward in a specific direction and/or rotated in another direction. The optical navigation circuit captures reflection of a light emitting to the structure to detect displacement of the image along a specific axis of the structure, and determines the user's operating behavior as a specific operation according to a change of the sensed displacement of the image.
