TOUCH LOCATION DETERMINATION INVOLVING MULTIPLE TOUCH LOCATION PROCESSES

摘要

Touch location determination approaches involving a plurality of touch location techniques are described. Each touch location technique is capable of independently determining a location of a touch within a touch area of the touch sensitive device. The touch location determination made by at least one touch location technique is enhanced using touch location information associated with the touch acquired from one or more other touch location techniques. One touch location technique may use a different type of sensor, signal, and/or algorithm from the one or more other touch location techniques.
