发明名称 NAVIGATION APPARATUS AND RELATED ACTUATING METHOD
摘要 A method capable of detecting position of an object for actuating a navigation apparatus is disclosed in the present invention. The navigation apparatus includes a casing, an optical touch unit and a touch processing unit. The optical touch unit is disposed on an upper surface of the casing. The touch processing unit is disposed inside the casing and electrically connected to the optical touch unit. The actuating method includes outputting an optical detecting signal, receiving an optical reflecting signal from the object, analyzing the optical reflecting signal to obtain intensity of the optical reflecting signal, determining whether the object is located above the optical touch unit according to the intensity, and switching the touch processing unit into a normal mode when the object is located above the optical touch unit.
