First Claim
Patent Images
1. A method of selecting input of a computing system including a touch sensing surface, the method comprising:
- detecting a set of one or more contacts touched down on or near the surface;
determining a number of the one or more contacts;
determining whether the one or more contacts are in motion;
determining whether the one or more contacts are decelerating; and
selecting an input based on the number of contacts, whether the contacts are in motion, and whether the contacts are decelerating.

Abstract
Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing, multi-touch surface. Identification and classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.
