Abstract

A computing device processes input by determining one or more inputs corresponding to a user interacting with an input interface. In an embodiment, the input interface may correspond to a button state or to a multi-state input interface. A value corresponding to an amount of pressure applied by the user is determined on the computing device. The value is determined during an instance or duration in which the user is interacting with the input interface. The value for the applied pressure is determined apart from the input. In one embodiment, the value is determined using a force sensor that is separate from the input interface. An operation is then performed that is responsive to the determined amount of pressure, as well as to the one or more inputs.
