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 users when multiple users simultaneously touch any of the antennas.
Claims26
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.

A method for operating a multi-user touch system, comprising:
- transmitting uniquely identifiable signals to a plurality of antennas mounted on a surface;
- receiving the uniquely identifiable signals when users capacitively coupled the transmitted signal by touching the antennas;
- and
- associating specific touched antennas with particular users when multiple users simultaneously touch any of the plurality of antennas.
