US Patent 9354731 Multi-dimension touch input

A computing device can use a combination of input technologies in order to provide for more accurate input determinations, as well as to reduce the number of false inputs determined. A capacitance-sensing approach, which can be self- or mutual-capacitance in nature, can be combined with a force- or pressure-sensing approach. The approaches can share at least some components, such as one or more electrodes, in order to conserve space on the device and reduce cost. An input at one or more locations in one or more modes then can be accepted only if the input is determined to be valid for both approaches, which can prevent false input resulting from keys or other metallic objects being detected by the capacitance components, as well as objects applying pressure to the device as detected by the force sensing components.
