Abstract
A projected capacitive touch and force sensor capable of detecting multiple touches thereto and forces thereof is coupled with a digital device having multi-touch and force decoding capabilities. Once a touch has been established, a force thereof may be assigned to the touch based upon the magnitude of change of capacitance values determined during scans of the projected capacitive touch and force sensor. The touch forces applied to the touch sensor from the associated tracked touch points may be utilized in further determining three dimensional gesturing, e.g., X, Y and Z positions and forces, respectively.
