Abstract: A contact's interaction with a sensing array is subject to several external and internal stimuli which may impact a processing unit's confidence in the characteristics of that interaction or the presence of the interaction itself. Fidelity of user action is greatly improved with a step-wise and holistic analysis of a contact on an array of capacitance sensors, which allows for repetition of certain steps of processing or the entire operation if threshold confidence levels are not achieved.

The trellis pattern of conductors forms a multiple capacitors and the processing device is configured to sense a capacitance of each of the capacitors. A host is coupled to the processing device. The host includes decision logic to determine a state of the trellis pattern of conductors responsive to a signal that indicates a capacitance of one or more capacitors sensed by the processing device.

Abstract: An apparatus includes a memory and a processing device comprising touch sorting logic. The touch sorting logic sorts the raw touch position data in two stages. In each of the stages, the touch sorting logic predicts the centroid positions for each touch of the plurality of touches, compares the predicted centroid positions for each touch and indexes the centroid position for each touch based on the predicted centroid position that is closest to the raw touch position data. The sorted touch position data is sorted according to the touch index assigned to each of the centroid positions for each of the plurality of touches.
