1. A system for determining a touch contact location, comprising:

  • a communication interface configured to receive a signal that has been disturbed by a touch input on a surface; and

    a processor coupled with the communication interface and configured to;

    transform the received signal to determine a spatial domain signal;

    compare the spatial domain signal with an expected signal associated with a potential location of a source of a disturbance caused by the touch input; and

    determine the touch contact location of the touch input based at least in part on the comparison.
