First Claim
Patent Images
1. A multi-touch device comprising:
- a touchscreen;
a processor coupled to the touchscreen; and
a haptic feedback system coupled to the processor;
wherein the processor is configured to sense at least two generally simultaneous touches on a touchscreen;
wherein the processor is configured to generate through the haptic feedback system a dynamic haptic effect in response to the sensing; and
wherein the dynamic haptic effect is a vibration that comprises a variation of at least one parameter that is based on a user interaction with the touchscreen.
