Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A user input device comprising: a communications interface; a touch sensitive pad having a plurality of touch sensitive elements including: at least one central touch sensitive element with a first touch sensitive element value; and a set of touch sensitive elements located about the at least one central touch sensitive element, wherein each of the set of touch sensitive elements have a second touch sensitive element value being lower to that of th…
