A method for using existing touchpad hardware to detect and track multiple objects such as fingers that are in contact with a touchpad, wherein the method extracts information from data that is already being collected, wherein analysis of the data is simplified by identifying objects by only looking for a positive slopes and negative slopes to identify multiple objects in data from the touchpad.

Multitouch input to touchpad derived from positive slope detection data

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.

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
