Abstract
A system for generating haptic effects senses at least two generally simultaneous touches on a touchscreen and, in response, generates a dynamic haptic effect.
Claims18
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 adapted to sense at least two generally concurrent touches on a touchscreen;
- and
- the processor is adapted to generate through the haptic feedback system a dynamic haptic effect in response to the sensing;
- wherein the dynamic haptic effect is a vibration that comprises a variation of at least one parameter.
5 more elements
A computer readable medium having instructions stored thereon that, when executed by a processor, causes the processor to:
- sense at least two generally concurrent touches on a touchscreen;
- and
- generate a dynamic haptic effect in response to the sensing;
- wherein the dynamic haptic effect is a vibration that comprises a variation of at least one parameter.
