Control system for differentiating multiple users

A system with differentiated user controls, comprising:

• a plurality of controls;
• a conductive surface arranged in a close proximity to each control;
• a transmitter connected to the conductive surfaces, the transmitter emitting a unique signal to each conductive surface;
• a plurality of electrodes, each electrode arranged in close proximity to a particular one of a plurality of users of the controls;
• a receiver connected to each corresponding electrode;
• and
• means for associating a particular user with a particular control when the particular user is capacitively coupled to a particular conductive surface via the electrode, the receiver and the transmitter.
