1. A system comprising:
- a surface comprising a multi-mode area;
a plurality of touch sensors coupled to the surface, the plurality of touch sensors configured to generate at least one sense signal based on sensed user contact with the surface;
a plurality of motion sensors, the plurality of motion sensors configured to generate a motion signal based on sensed vibrations of the surface; and
a processor in signal communication with the surface, the plurality of touch sensors, and the plurality of motion sensors, wherein the processor is configured to determine mode of operation associated with the multi-mode area based on interpretation of at least one of the generated at least one sense signal and the motion signal associated with the multi-mode area.

Abstract
A method and system that integrates a numeric keypad with a touchpad in the same physical location on a touch-sensitive display device. Operational mode of the same location is automatically determined based on user actions with the display or based on a manual entry by the user. The system operates in at least one mode of operation selected from: numpad mode, touchpad mode, keyboard mode and auto-detect mode. A visual indicator communicates with the user which mode is the current mode.
