CIRCUITS, SYSTEMS, AND METHODS FOR PROCESSING THE PROXIMITY OF LARGE OBJECTS, INCLUDING LARGE OBJECTS ON TOUCH SCREENS

摘要

A method of sensing at least one object in proximity to an array of sensors can include making a determination that an object greater than a predetermined size has been detected; defining an ignore zone that includes sensor locations of the object and sensor locations surrounding those of the object; and removing the ignore zone after a predetermined duration; wherein the proximity of objects outside of the ignore zone are processed differently than the proximity of objects inside of the ignore zones.
