Abstract
Disclosed is a controller that modulates the phase, amplitude or phase and amplitude of the signal. The modulated signals are transmitted and interact with an object. Backscattered signals are received by the controller. The received backscattered signals are analyzed to determine the position, movement and/or touch event of a hand or other object.
