1. A method for selecting a state of a computing system including a touch sensing surface, the method comprising:
- detecting a set of plurality of contacts touched down on or near the surface;
detecting a liftoff of a first subset of one or more contacts of the set, wherein a second subset of one or more contacts of the set remains touched down;
determining a motion of the first subset, prior to the liftoff, from a first position on the surface to a second position on the surface;
selecting, while the first subset remains lifted off from the surface after the liftoff, one of a plurality of post-liftoff states, wherein the selection is determined by first information including the motion of the first subset, prior to the liftoff, from the first position on the surface to the second position on the surface; and
the selection occurs while the second subset remains touched down.

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.

1. A method for selecting a state of a computing system including a touch sensing surface, the method comprising:
-
detecting a set of plurality of contacts touched down on or near the surface; detecting a liftoff of a first subset of one or more contacts of the set, wherein a second subset of one or more contacts of the set remains touched down; determining a motion of the first subset, prior to the liftoff, from a first position on the surface to a second position on the surface; selecting, while the first subset remains lifted off from the surface after the liftoff, one of a plurality of post-liftoff states, wherein the selection is determined by first information including the motion of the first subset, prior to the liftoff, from the first position on the surface to the second position on the surface; and the selection occurs while the second subset remains touched down. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A non-transitory computer-readable storage medium storing computer-readable program instructions executable to perform a method of selecting a state of a computing system including a touch sensing surface, the method comprising:
-
detecting a set of plurality of contacts touched down on or near the surface; detecting a liftoff of a first subset of one or more contacts of the set, wherein a second subset of one or more contacts of the set remains touched down; determining a motion of the first subset, prior to the liftoff, from a first position on the surface to a second position on the surface; selecting, while the first subset remains lifted off from the surface after the liftoff, one of a plurality of post-liftoff states, wherein the selection is determined by first information including the motion of the first subset, prior to the liftoff, from the first position on the surface to the second position on the surface; and the selection occurs while the second subset remains touched down. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)

45. An apparatus comprising:
-
a touch sensing surface; and an input system that detects a set of plurality of contacts touched down on or near the surface, detects a liftoff of a first subset of one or more contacts of the set, wherein a second subset of one or more contacts of the set remains touched down, determines a motion of the first subset, prior to the liftoff, from a first position on the surface to a second position on the surface, selects, while the first subset remains lifted off from the surface after the liftoff, one of a plurality of post-liftoff states, wherein the selection is determined by first information including the motion of the first subset, prior to the liftoff, from the first position on the surface to the second position on the surface; and the selection occurs while the second subset remains touched down. - View Dependent Claims (46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66)
