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.
Claims25
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.
A non-transitory computer-readable storage medium storing computer-readable program instructions executable to perform 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.
An apparatus comprising:
- a touch sensing surface;
- and
- an input system that
- detects a set of one or more contacts touched down on or near the surface;
- determines a number of the one or more contacts;
- determines whether the one or more contacts are in motion;
- determines whether the one or more contacts are decelerating;
- and
- selects an input based on the number of contacts, whether the contacts are in motion, and whether the contacts are decelerating.
