The controller comprises circuitry to drive and sense signals on interacting pairs of conductors (the transmitting conductor or receiving conductor can act as the drive side, or as the sense side). Signals are processed to analyze changes in measured signal and analyzed to determine interior movement. When the controller is deployed proximate to human skin, movement of muscles, tendons and bones within the skin are reflected in the measured signals. ## Claims ### Claim 1 An apparatus comprising: a transmitting conductor adapted to transmit signals;
