Abstract
A device comprising a body comprising an elongated housing with at least a first conductive tip formed at a distal end and at least one sense electrode on the body; a capacitance sense circuit disposed within the housing and configured to sense a capacitance of the sense electrode to generate a proximity result in response to contact with a human body; and a signal generator circuit disposed within the housing and configured to activate a position signal in response to the proximity result, the position signal being driven at the tip of the device.
