Abstract

Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multipoint sensing device such as a multipoint touch screen where the data pertains to touch input with respect to the multipoint sensing device, and identifying at least one multipoint gesture based on the data from the multipoint sensing device.

Claims

1. A computer implemented method comprising:

presenting a virtual wheel;

detecting at least a first finger over the virtual wheel;

associating the finger to the virtual wheel; and

generating control signals when the finger is moved about the virtual wheel.

2. The method as recited in claim 1 further comprising:

rotating the presented virtual wheel when the finger is moved about the virtual wheel.

3. The method as recited in claim 1 wherein the control signals implement scrolling on a display.
