Patent Images
1. A touch-based method, comprising:
- (a) detecting a user input that occurs over a multipoint sensing screen or pad, the user input including one or more inputs, each input having a unique identifier;
(b) during the user input, classifying the user input as a tracking or selecting input when the user input includes one unique identifier or a gesture input when the user input includes at least two unique identifiers;
(c) performing tracking or selecting during the user input when the user input is classified as a tracking or selecting input;
(d) performing one or more control actions during the user input when the user input is classified as a gesturing input.
