Abstract

The present invention relates to touch sensor detector systems and methods incorporating an interpolated variable impedance touch sensor array and specifically to such systems and methods for gesture recognition and associating a UI element with the recognized gesture. In one embodiment, the present invention provides a variable impedance array (VIA) system for receiving a gesture that includes: a plurality of physical VIA columns connected by interlinked impedance columns; a plurality of physical VIA rows connected by interlinked impedance rows; and a processor configured to interpolate a location and/or pressure of the gesture in the physical columns and rows from an electrical signal from a plurality of column drive sources (connected to the plurality of physical VIA columns through the interlinked impedance columns) sensed at a plurality of row sense sinks (connected to the plurality of physical VIA rows through the interlinked impedance rows).
