Abstract
A touch sensitive device uses an iterative method for determining the location of a touch on a touch sensitive surface. The touch sensitive device includes a touch plate and a plurality of sensors configured to sense vibrations propagating in the touch plate. Signals responsive to the vibrations caused by the touch are generated. The touch location is approximated and the signals are adjusted using the approximate touch location. The touch location is determined using the adjusted signals.
