Claim One:
1. A method for determining touch events on a touch panel, the method comprising: identifying initial coordinate locations representative of the touch events based at least on template fingerprints, wherein a template fingerprint of the template fingerprints is an acoustic profile of a signal that represents a sound recognized when a coordinate location on the touch panel is touched, wherein the template fingerprint is established prior to the touch events, and wherein one of the initial coordinate locations corresponds to a primary touch event; identifying subsequent coordinate locations representative of the touch events based at least on the template fingerprints; gathering coordinate locations that are within a distance threshold to form groups of coordinate locations; identifying one or more secondary touch events that correspond to one or more of the groups with a predetermined number of coordinate locations identified within a predetermined period of time; and identifying a secondary touch event of the one or more secondary touch events based at least on a ratio between a score associated with the primary touch event and a score associated with the secondary touch event.
