SYSTEM AND METHOD FOR OBSERVING THE SWIMMING ACTIVITY OF A PERSON
First Claim
1. A system for observing a swimming activity of a person, comprising a waterproof housing (BET) comprising a motion sensor (MS), and furnished with fixing means (BEL) for securely fastening the housing (BET) to a part of the body of a user, characterized in that it comprises analysis means (AN) for analyzing the signals transmitted by the motion sensor (MS) to at least one measurement axis and which are adapted for determining the type of swimming of the user as a function of time by using a hidden Markov model with N states corresponding respectively to N types of swimming.

15. A method for observing a swimming activity of a person on the basis of measurements transmitted by a motion sensor fixed in a waterproof manner to a part of the body of a user, characterized in that the signals transmitted by the motion sensor to at least one measurement axis are analyzed to determine a type of swimming of the user as a function of time by using a hidden Markov model with N states corresponding respectively to N swimming types.
