Abstract
Vehicle including a seat on which an occupant sits, a set of at least one electric field antenna arranged in the seat, and a control unit coupled to the antenna set and configured to direct one or more antennas to transmit an oscillating electric field at a frequency that enables the electric field to be conducted through the seated occupant. An electrical circuit is coupled to a vehicular component and has a conductive surface in a position accessible by the occupant's finger. Proximity of the occupant's finger to or contact with the conductive surface, when an antenna is transmitting an oscillating electric field conducted through the occupant, causes a capacitive coupling to develop between the occupant and the conductive surface and completion of the circuit. This enables control of the component by the occupant's finger, which may be adjustment or change in the state, condition or operation of the component.
