A system and method for detecting and tracking multiple objects on a touchpad or touchscreen, wherein the method provides a new data collection algorithm, wherein the method reduces a calculation burden on a processor performing detection and tracking algorithms, wherein multiple objects are treated as elements of a single object and not as separate objects, wherein the location of the objects are treated as corners of a quadrilateral outline of a single object when two objects are detected, and wherein the multiple objects are capable of being tracked so as to perform a multi-touch rotation gesture. |
