14. The multi-touch device 12, wherein the sensing comprises determining a location of the touches.
-
15. The multi-touch device 12, wherein the sensing comprises determining a number of touches on the touchscreen.
-
16. The multi-touch device 12, wherein the dynamic haptic effect is a vibration that comprises a variation of at least one parameter.
-
17. The multi-touch device 16, wherein the at least one parameter is one or more of amplitude, frequency and duration.
-
18. The multi-touch device 16, wherein the sensing comprises a first determination that a first finger and a second finger are being moved apart, and the dynamic haptic effect comprises increasing the parameter.
-
19. The multi-touch device 16, wherein the sensing comprises a second determination that the first finger and a second finger are being moved together, and the dynamic haptic effect comprises decreasing the parameter.
-
20. The multi-touch device 16, wherein the sensing comprises a determination that a first finger and a second finger are being rotated, and the dynamic haptic effect comprises generating a detent simulation from the variation.
-
21. The multi-touch device 16, wherein the sensing comprises a determination that a first finger and a second finger created a boundary box and the box is being dragged, wherein the dynamic haptic effect comprises generating a dragging speed indication from the variation.
-
22. The multi-touch device 16, wherein the dynamic haptic effect is generated substantially solely at points of contact of the touches on the touchscreen.
-
23. A computer readable medium having instructions stored thereon that, when executed by a processor, causes the processor to:
-
sense at least two generally simultaneous touches on a touchscreen; and generate a dynamic haptic effect in response to the sensing.
-
-
24. A system for generating haptic effects comprising:
-
means for sensing at least two generally simultaneous touches on a touchscreen; and means for generating a dynamic haptic effect in response to the sensing.
