Abstract
Methods and systems implement touch sensors or force sensitive materials disposed on the case of a computing device in order to enable user input gestures to be performed on portions of the device case. The force sensitive elements may generate an electrical signal in response to a gesture, such as a tap, squeeze, swipe or twist. The properties of the generated electrical signal may be compared to various reference templates to recognize particular input gestures. The force sensitive elements may operate in conjunction with more traditional input methods, such as touch-screen display and electromechanical buttons. By enabling user input gestures on the case of computing devices, the various aspects permit one hand operation of the devices including intuitive gestures that do not require the users focused attention to accomplish. Thus the various aspects may enable users to utilize their computing devices in situations not suitable to conventional user input technologies.
