1. A multi-user touch system, comprising:
- a touch sensitive surface including a plurality of antennas mounted thereon;
a transmitter configured to transmit uniquely identifiable signals to each antenna;
plurality of receivers, each receiver capacitively coupled to a different user, the receivers configured to receive the uniquely identifiable signals;
means for associating a specific antenna with a particular user when multiple users simultaneously touch any of the plurality of antennas.

Abstract
A multi-user touch system includes a surface on which are a pattern of mounted antennas. A transmitter transmits uniquely identifiable signals to each antenna. Receivers are capacitively coupled to different users, the receivers are configured to receive the uniquely identifiable signals. A processor then associates a specific antenna with a particular user when multiple users simultaneously touch any of the antennas.
