Abstract
Highly expressive and flexibly programmable foot-operated controllers are described. Specific implementations are intended for musical applications and allow musicians an unprecedented degree of control of a wide variety of musical components and subsystems for recording and/or performance.
Claims20
A sensor array, comprising:
- piezoresistive fabric;
- a plurality of sets of traces adjacent a same side of the piezoresistive fabric, each set of traces forming a corresponding sensor with a corresponding portion of the piezoresistive fabric;
- and
- sensor circuitry configured to receive a sensor signal from each set of traces, each sensor signal representing pressure applied to a surface of the sensor array near the corresponding sensor.

A method for generating control information representing pressure applied to a surface associated with a sensor array by an object, comprising:
- receiving a plurality of sensor signals, each sensor signal representing interaction of a portion of piezoresistive fabric and a corresponding set of traces adjacent a same side of the piezoresistive fabric resulting from the pressure on the surface;
- digitizing the sensor signals;
- and
- generating the control information from the digitized sensor signals, the control information representing movement of the object relative to the surface, the control information also representing a time-varying magnitude of the pressure.
