METHOD AND APPARATUS FOR DETECTING LIFT OFF ON A TOUCHSCREEN

摘要

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.
