1. A gaming system comprising:
- a memory device;
a microprocessor; and
a composite touchscreen including;
a display,an acoustic pulse recognition touchscreen subsystem,a capacitive touchscreen subsystem,one or more touchscreen controllers, andwherein the touchscreen is configured to detect an x-y coordinate location of a touch of the touchscreen with the acoustic pulse recognition subsystem and to detect a simultaneous lift-off of an object from the touchscreen with the capacitive touchscreen subsystem.

Abstract
A composite touchscreen incorporates acoustic pulse recognition sensing and capacitive sensing technology. The hybrid screen incorporates the advantages of each technology while minimizing the drawbacks. When such a screen is incorporated in a gaming device specialized gestures and functions can be implemented that enhance the interface, the range of games, and the gaming experience.
