Abstract
A touch sensitive pad with a plurality of touch sensitive elements and processing circuitry coupled to a communications interface and to the touch sensitive pad for scanning the plurality of touch sensitive elements to measure a plurality of touch sensitive element values. The plurality of touch sensitive element values is compared to a hovering finger threshold pattern. Upon a favorable comparison, a hovering finger condition is determined, and a position of the hovering finger in three-dimensions is detected with respect to the touch sensitive pad. The plurality of touch sensitive element values is compared to a touching finger threshold pattern. Upon a favorable comparison, a touching finger condition is determined, and a position of the touching finger is detected upon the touch sensitive pad.
