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.

主权项

1. A touch sensitive device, comprising:
a plurality of touch detectors, comprising:
one or more first touch detectors configured to determine a touch location of a touch on a touch panel using one or more first touch location techniques; andone or more second touch detectors configured to acquire touch location information using one or more second touch location techniques; and processing circuitry coupled to the one or more first touch detectors and the one or more second touch detectors, the processing circuitry configured to provide an enhanced accuracy touch location determination based on a combination of the touch location determined by the one or more first touch detectors and the touch location information acquired using the one or more second touch detectors.
