DEVICE AND METHOD FOR THE CLASSIFICATION AND THE RECLASSIFICATION OF A USER ACTIVITY
First Claim
1. A portable device to monitor at least an activity of a user, said portable device comprising at least:
- A first sensor (310) configured to capture signals representative of at least a physical parameter induced by at least an activity of the user;
A channel of communication to processing capabilities, said processing capabilities configured to;
Perform a first classification algorithm (320) to classify the signals representative of the at least a physical parameter over a first period of time into a first set of classes of activities of the user;
Perform a second classification algorithm (340) to classify the at least an activity of the user at the output of the at least first classification algorithm over a second period of time which includes the first period of time using a second set of classes which is different from the first set of classes

Abstract
The invention relates to a portable device to monitor at least an activity of a user The portable device comprises at least a first sensor configured to capture signals representative of at least a physical parameter induced by at least an activity of the user, and a channel of communication to processing capabilities. The processing capabilities are configured to perform a first classification algorithm to classify the signals representative of the at least a physical parameter over a first period of time into a first set of classes of activities of the user, and to perform a second classification algorithm to classify the at least an activity of the user at the output of the at least first classification algorithm over a second period of time which includes the first period of time using a second set of classes which is different from the first set of classes
The invention also relates to a method to monitor, a computer program and a system to monitor at least an activity of a user.
