Title: APPARATUS FOR SENSING USER INPUT
Abstract:
An apparatus for sensing user input includes a first strain gauge grouping at an inner surface of a housing of a device, and a second strain gauge grouping at the inner surface of the housing. The apparatus includes a circuit coupled to the first and second strain gauge groupings. The circuit: (i) receives a first signal from the first strain gauge grouping in response to user input at the housing over a location of the first strain gauge grouping, (ii) indicates a first type of user input has been received in response to receipt of the first parameter signal, (iii) receives a second signal from the second strain gauge grouping in response to user input at the housing over a location of the second strain gauge grouping, and (iv) indicates that a second type of user input has been received in response to receipt of the second parameter signal.
