1. A method for determining a location of a touch on a touch sensitive device having a touch plate and a plurality of vibration sensors configured to sense vibrations propagating in the touch plate, the method comprising:

  • sensing dispersive vibrations at each of the vibration sensors, the vibrations caused by the touch on the touch plate;

    determining an amount of dispersion in the dispersive vibrations sensed at each of the vibration sensors;

    calculating a distance between the touch and each of the vibration sensors corresponding to the amount of dispersion in the dispersive vibrations sensed at each of the vibration sensors; and

    determining the touch location using at least some of the calculated distances.
