Claim:
1. A system for classifying finger touch events and generating an event corresponding to one of a plurality of interaction layers, the system comprising: a touch screen configured to display interactive elements; one or more vibro-acoustic sensors coupled to the touch screen and configured to sense vibro-acoustic signals; a touch event detector configured to monitor the onset of user touches; a buffer to save vibro-acoustic signals sensed by the one or more vibro acoustic sensors, wherein the touch event detector is further configured to detect touch events in which the touch screen is touched by a first finger part or a second finger part of a user, and wherein the touch events result in generating the vibro-acoustic signals; a classifier configured to classify the vibro-acoustic signals; a first interaction layer configured to activate a first function responsive to the touch event is by said first finger part touching an interactive element; and a second interaction layer configured to activate a second function responsive to the touch event is by said second finger part performing a gesture on the touch screen.
