Abstract
A hybrid sensor module and methods of operating the same are provided. In one embodiment, the hybrid sensor module includes: (i) a touch sensor configured to sense motion of an object in proximity to a surface of the touch sensor; (ii) an optical navigation sensor (ONS) configured to illuminate the object through the surface of the touch sensor and to sense motion of the object based on light returned from the object; and (iii) a controller electrically coupled to the touch sensor and the ONS to process the sensed motion of the object and to generate an output signal in response to the sensed motion, wherein the controller is configured to dynamically adjust a tracking resolution of the hybrid sensor module based on a characteristic of the sensed motion. Other embodiments are disclosed.
