Optical navigation sensor and method

摘要

Optical navigation sensors and methods are provided for use in an input device. In one embodiment, the input device comprises: (i) a button configured to in a first mode of operation of the input device receive user input when a surface of the button is pressed; (ii) an optical navigation sensor (ONS) configured to in a second mode of operation of the input device illuminate an object in proximity to the surface of the button and to sense and provide input related to motion of the object; and (iii) means for disabling input from the ONS in the first mode of operation. Other embodiments are also disclosed.
