1. A method for determining a person'"'"'s activity in surroundings equipped with electrical appliances that are switchable, in response to a command from the person, between an ‘
- on’
mode, in which the electrical appliance radiates an electromagnetic field corresponding to a characteristic magnetic signature, and an ‘
off’
mode, in which the electrical appliance does not radiate any electromagnetic field or radiates an electromagnetic field corresponding to a magnetic signature different from the magnetic signature characterizing the same appliance in ‘
on’
mode, wherein the method comprises;
measuring a magnetic field produced by one of the electrical appliances by means of a magnetometer carried by the person,identifying an electrical appliance in ‘
on’
mode in proximity to the magnetometer by comparing the measured magnetic field with the pre-recorded magnetic signatures of electrical appliances in ‘
on’
mode, anddetermining the activity of the person on the basis of a pre-recorded activity identifier associated with the electrical appliance identified as being in ‘
on’
mode on the basis of its magnetic signature.

Abstract
This method for determining a person'"'"'s activity in surroundings equipped with electrical appliances that are switchable, in response to a command from the person, between an ‘on’ mode and an ‘off’ mode, wherein the method comprises:
- the measuring of the magnetic field produced by one of the electrical appliances by means of a magnetometer carried by the person,
- the identifying of the electrical appliance in ‘on’ mode in proximity to the magnetometer by comparing the measured magnetic field with the pre-recorded magnetic signatures of these electrical appliances in ‘on’ mode, and
- the determining of the activity of the person on the basis of a pre-recorded activity identifier associated with the electrical appliance identified as being in ‘on’ mode on the basis of its magnetic signature.

8. A non transitory tangible information-recording medium having encoded thereon software for determining a person'"'"'s activity in surroundings equipped with electrical appliances that are switchable, in response to a command from the person, between an ‘
- on’
mode, in which the electrical appliance radiates an electromagnetic field corresponding to a characteristic magnetic signature, and an ‘
off’
mode, in which the electrical appliance does not radiate any electromagnetic field or radiates an electromagnetic field corresponding to a magnetic signature different from the magnetic signature characterizing the same appliance in ‘
on’
mode, said software comprising instructions that, when executed by an electronic computer, cause said electronic computer to;receive data provided by a magnetometer carried by the person, said data being representative of measurements of the magnetic field produced by one of the electrical appliances, identify an electrical appliance in ‘
on’
mode in proximity to the magnetometer by comparing the measured magnetic field with pre-recorded magnetic signatures of electrical appliances in ‘
on’
mode, anddetermine the activity of the person on the basis of a pre-recorded activity identifier associated with the electrical appliance identified as being in ‘
on’
mode on the basis of its magnetic signature.

9. A system for determining the activity of a person in surroundings, the system comprising:
-
a magnetometer carried by the person, a data base containing pre-recorded magnetic signatures of electrical appliances present in the surroundings, each of the electrical appliances being switchable, in response to a command from the person, between an ‘
on’
mode in which the electrical appliance radiates an electromagnetic field corresponding to a characteristic magnetic signature and an ‘
off’
mode in which the electrical appliance does not radiate any electromagnetic field or radiates an electromagnetic field corresponding to a magnetic signature different from the magnetic signature characterizing the same appliance in ‘
on’
mode, each of the magnetic signatures contained in the data base being capable of enabling the identification of the electrical appliance in ‘
on’
mode from among the different electrical appliances present in the surroundings, anda computer capable of; identifying the electrical appliance in ‘
on’
mode in proximity to the magnetometer by comparison of the electromagnetic field measured by the magnetometer with the pre-recorded magnetic signatures pre-recorded in the database, anddetermining the activity of the person on the basis of at least one pre-recorded activity identifier associated with the identified electrical appliance as being in ‘
on’
mode on the basis of its magnetic signature. - View Dependent Claims (10)
