Abstract
A sensor device for determining a position of an operator's finger/hand, comprises a handle portion comprising one or more touch sensing electrode portions. Each touch sensing electrode portion is configured to provide an electrical signal in response to the operator's finger/hand being on or near the one or more touch sensing electrode portions. The sensor device also comprises a measurement module configured to receive the or each electrical signal from the touch sensing electrode portion(s) and determine a position of the operator's finger/hand relative to one or more of the touch sensing electrode portions based on the or each electrical signal. The or each touch sensing electrode portion is formed of or comprises a non-metallic conductive material.
