1. A method for detecting an input to a device comprising:
- providing a prompt to select a user configurable input type;
receiving a user input, which defines a function with the input type, a first function being defined with a soft touch input type and a second function being defined with a hard touch input type;
detecting an input to a touch screen of the device via a plurality of acoustic sensors;
determining the type of the input based on an acoustic characteristic of the input detected via the plurality of acoustic sensors; and
performing the defined function based on the type of the input,wherein the characteristic of the input distinguishes between a touch input from a fingertip and a knuckle.
