Systems and methods are disclosed for providing wireless remote control of devices, where the sensing/transmitting device is worn by, or affixed to, the operator, and responds in real-time to position or movements. The technology enables the operator to control remote devices, even while the operator is engaged in other activities. For an exemplary musical performance application, the remote control apparatus may take the form of a normal sized ring worn on a finger of a hand that the musician uses to play a musical instrument. The ring senses position or movement, e.g. of one or more fingers of the hand. In the examples, the remote control apparatus uses a capacitive measurement technique to measure an electrical field generated in the vicinity of the hand indicative of position. The musician or operator can finely control a device with the system, e.g. to provide nuanced control of audio effects during the performance.
