DEVICE AND METHOD FOR RECOGNIZING GESTURES FOR A USER CONTROL INTERFACE
First Claim
1. A gesture-recognition method for recognizing gestures in the context of user interface control, said method being implemented by a gesture-recognition device, the method comprising receiving gyroscopic data representing a gesture executed with a dedicated instrument comprising a gyroscopic sensor, wherein the gesture recognition device includes a network of artificial neurons comprising output neurons associated respectively with the gestures that said device is adapted for recognizing, and wherein the method further comprises:
- determining, by the network of artificial neurons, a correlation between the received gyroscopic data and gyroscopic data relating to a supervised learning and pre-recorded in a database, the network of artificial neurons implementing an activation function of the sigmoid type and, for the received gyroscopic data and for each output neuron, supplying a probability that said received gyroscopic data correspond to the gesture associated with said output neuron;
recognizing or not the executed gesture according to said correlation, the only data representing the executed gesture taken into account being said gyroscopic data; and
transposing each recognized gesture into a user interface command.

Abstract
In the context of a user interface control, a gesture-recognition device: receives gyroscopic data representing a gesture executed with a dedicated instrument including a gyroscopic sensor; determines a correlation between the received gyroscopic data and gyroscopic data relating to a supervised learning and pre-recorded into a database; recognizes or not the executed gesture according to said correlation, the only data representing the executed gesture taken into account being said gyroscopic data; transposes each recognized gesture into a user interface command.
