Abstract
Implementations relate to capacitive sensing of hand presence at a control input device. In some implementations, a control input device includes a support structure, a handle moveable in one or more degrees of freedom with reference to the support structure, and a capacitive sensor circuit electrically coupled to the handle. The handle is isolated from electrical ground and is an antenna for the capacitive sensor circuit.
