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 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.

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 coupled with 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 touch signals; classifying the vibro-acoustic 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 the classified vibro-acoustic signals; and selectively activating a first function from a first interaction layer if the interactive element is touched by the first finger part or a second function from a second interaction layer if a gesture is performed on the touch screen by the second finger part. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. A non-transitory 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 on 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 touch screen 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 the vibro-acoustic signals; determining whether the first finger part or the second finger part is used to touch the touch screen based on said classifying; and activating a first function from a first interaction layer based on the first finger part touching the interactive element, and activating a second function from a second interaction layer based on the second finger part performing a gesture on the touch screen. - View Dependent Claims (24)
