Abstract
Geometrically based system and method for receiving capacitive sensory input. User input may be received by a capacitive sensing pad. A signal may be generated by the capacitive sensing pad. The signal may indicate a size of an area in which the user input is received. The signal may be received by an input composed in processing circuitry and coupled to the capacitive sensing pad. A location of the user input may be determined by the processing circuitry based on the signal.
