METHOD TO RECOGNIZE A GESTURE AND CORRESPONDING DEVICE
First Claim
1. Method to recognize a gesture made in direct or indirect contact on a physical object, wherein said method comprises the following steps:
- associating a device using said method in contact with said physical object;
supplying an entrance signal generated by a gesture made in direct or indirect contact on said physical object;
segmenting said entrance signal to obtain a group of signal segments and at least one physical value processed from said entrance signal;
processing at least a characteristic vector of signal features for each segment of said group of signal segments using said at least one physical value in order to learn metric function between gestures;
supplying a specific exit signal correlated to the specific gesture.

Abstract
The present disclosure concerns a method to recognize a gesture, namely a physical action, made in direct or indirect contact on a physical object, wherein said method comprises:
associating a device using said method in contact with said physical object;
supplying an entrance signal generated by a gesture made in direct or indirect contact on said physical object;
segmenting said entrance signal to obtain a group of signal segments and at least one physical value processed from said entrance signal;
processing at least a characteristic vector of signal features for each segment of said group of signal segments using said at least one physical value in order to learn metric function between gestures;
supplying a specific exit signal correlated to the specific gesture.
Further, the present invention concerns also a device to recognize a gesture using said method to recognize a gesture.

14. Device to recognize a gesture made in direct or indirect contact on a physical object, comprising:
-
a transducer associable in contact with said physical object and configured to detect the vibrations and/or sounds generated by the gesture made on said physical object; a reception unit configured to receive an entrance signal from said transducer generated from said gesture made on said physical object; a segmentation unit configured to receive said entrance signal and to obtain a group of signal segments and at least one physical value processed from said entrance signal; a processing unit configured to calculate at least one characteristic vector of signal features for each segment of said group of signal segments and said at least one physical value; a command unit configured to supply to a device a specific exit signal correlated to the specific gesture made. - View Dependent Claims (15, 16, 17, 18)
