Abstract:
The present invention relates to touch sensor detectors incorporating interpolated variable impedance touch sensor arrays and specifically to detectors for non-planar touch controls. Variable impedance touch sensor arrays are applied to the surface of objects, inside objects, or other objects such that touches are detected directly or indirectly from the non-planar touch controls. An exemplary system includes a plurality of sensor panels on a plurality of device and a processor communicatively coupled to the sensor panels. The sensor panels include a plurality of physical VIA columns connected by interlinked impedance columns and a plurality of physical VIA rows connected by interlinked impedance rows. The processor detects touches at a first time at the sensor panels, determines that the two or more touches at the first time are arranged in a pattern corresponding to a predetermined gesture, and determines a relative pressure between the two or more touches.
