Abstract:
An input/output device for a computing device including one or more touch sensors and one or more force sensors. The touch sensors sense data including one or more locations at which a contact or near-contact occurs. The force sensor sense data including a measure of an amount of force presented at the one or more locations at which a contact occurs. The touch sensors and the force sensors responsive to signals occurring in response to whether the signals are in response to contact or in response to an amount of force. The input/output device also includes one or more circuits coupled to the touch sensors and to the force sensors, and capable of combining information from both sensors.
