Abstract
A touch sensor capable of detecting multiple touches thereto is coupled with a digital device having multi-touch decoding capabilities. These multi-touch decoding capabilities comprise touch data acquisition, touch identification, touch tracking and processed touch data output to a device associated with the touch sensor. Touch identification comprises touch location(s) peak detection, touch location(s) nudging and touch location(s) interpolation. Touch data acquisition locates potential touches on the touch sensor. Peak detection identifies where potential touch locations are on the touch sensor. Once a potential touch location(s) has been identified, touch location nudging examines each adjacent location thereto and interpolation examines the adjacent touch location values to generate a higher resolution location of the touch. Touch tracking compares time sequential 'frames' of touch identification data and then determines which touches are associated between frames for further processing, e.g., determining gesturing actions.
