A METHOD OF DETECTING AND TRACKING MULTIPLE OBJECTS ON A TOUCHPAD USING A DATA COLLECTION ALGORITHM THAT ONLY DETECTS AN OUTER EDGE OF THE OBJECTS AND THEN ASSUMES THAT THE OUTER EDGES DEFINE A SINGLE LARGE OBJECT

摘要

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 end-points of a single object when two objects are detected, and treated as a perimeter or boundary when more than two objects are detected.
