METHOD AND APPARATUS FOR CLASSIFYING A TOUCH EVENT ON A TOUCHSCREEN AS RELATED TO ONE OF MULTIPLE FUNCTION GENERATING INTERACTION LAYERS AND ACTIVATING A FUNCTION IN THE SELECTED INTERACTION LAYER
First 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 operating inside the device;
a touch event detector configured to monitor the onset of user touches;
a buffer to save touch and vibro-acoustic signals sensed by the one or more vibro acoustic sensors and the touchscreen, wherein the touch event detector is further configured to detect touch events in which the interactive element is touched by a first or a second finger part of a user, and wherein the touch events result in generating the touch and vibro-acoustic signals;
a touch and vibro-acoustic classifier configured to classify the touch and vibro-acoustic signals; and
a plurality of interaction layers of function generation responsive to whether the touch event is by said first finger part or by said second finger part.

Abstract
A system for classifying touch events of different interaction layers includes a touch screen configured to display an interactive element, one or more vibro-acoustic sensors coupled to the touch screen, a touch event detector configured to monitor the one or more vibro-acoustic sensors and 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 interactive element is touched by a first or a second finger part of a user, and wherein the touch events result in generating the vibro-acoustic signals, and a vibro-acoustic classifier is configured to classify the vibro-acoustic signals and activate corresponding functions in the different layers dependent upon which finger part is used.

16. A method for classifying touch events, the method comprising:
-
displaying an interactive element of a touch screen; monitoring one or more vibro-acoustic sensors operating inside the device to save vibro-acoustic signals sensed by the one or more vibro-acoustic sensors; detecting touch events in which the interactive element is touched by a first or a second finger part of a user, wherein the touch events result in generating touch event signals; classifying the vibro-acoustic and touch event signals; determining whether the first finger part or the second finger part is used to touch the interactive element on the touch screen based on classified vibro-acoustic and touch event signals; and selectively generating a corresponding function from a plurality of interaction layers depending upon whether the first finger part or the second finger part is used to touch the interactive element. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A computer readable medium containing instructions for classifying touch events, wherein execution of the program instructions by a processor causes the processor to carry out the steps of:
-
displaying an interactive element of a touch screen; monitoring one or more vibro acoustic sensors coupled to the touch screen to save vibro-acoustic signals sensed by the one or more vibro acoustic sensors; detecting touch events in which the interactive element is touched by a first or a second finger part of a user, wherein the touch events result in generating the vibro-acoustic signals; classifying at least one of the vibro-acoustic signals and the touch events; determining whether the first finger part or the second finger part is used to touch the interactive element on the touch screen based on said classifying; and initiating a function selection from different interaction layers depending whether the first finger part or the second finger part was used to touch the interactive element. - View Dependent Claims (24)
