Abstract

The disclosed embodiments include a method for monitoring the visual behavior of a person. In one embodiment, the method includes a person activity data providing step during which person activity data indicative of an activity of the person are provided; a person visual behavior data providing step during which person visual behavior data indicative of the visual behavior of the person related to said activity of the person are provided; reference visual behavior providing step during which a reference visual behavior data indicative of the reference visual behavior of the person based on said activity of the person are provided; and a comparing step during which the person visual behavior data and the reference visual behavior data are compared so as to deduce whether the person visual behavior is adapted with respect to said activity of the person.

First claim

The invention claimed is:

1. A method for monitoring the visual behavior of a person, the method comprising:
receiving person activity data indicative of an activity of the person;
receiving person visual behavior data indicative of the visual behavior of the person related to said activity of the person;
receiving environment data indicative of the environment of the person;
receiving reference visual behavior data indicative of a reference visual behavior of the person based on said activity of the person and the environment data; and
comparing the person visual behavior data and the reference visual behavior data to deduce whether the person visual behavior is adapted for said activity of the person, wherein
the receiving of the person visual behavior data comprises receiving the person visual behavior data from a head mounted device that measures at least part of the person visual behavior data.

2. The method according to claim 1 , further comprising:
receiving person head movement data indicative of the head movement of the person;
receiving reference head movement data indicative of the head movement data based on said activity of the person; and
comparing the person head movement data and the reference head movement data to determine whether the head movement of the person corresponds to the reference head movement given the current activity of the person.

3. The method according to claim 1 , wherein
the environment data relate to spectral features and intensity of the light received by the person.

4. The method according to claim 1 , further comprising receiving physiological data indicative of at least one parameter of the physiology of the person, wherein receiving the reference visual behavior comprises receiving the reference visual behavior data based on the physiology data.

5. The method according to claim 1 , wherein
the activity of the person comprises driving and the method further comprises receiving driving condition data indicative of driving conditions, wherein the reference visual behavior data are provided based on the driving condition data.

6. A method for determining a reference visual behavior corresponding to an activity of a person, the method comprising:
receiving person visual behavior data indicative of a visual behavior of the person;
receiving person activity data indicative of a current activity of the person;
receiving performance data indicative of the performance of the person when carrying out the current activity;
recording values of the person visual behavior data and the performance data;
receiving environment data indicative of the environment of the person, the environment data corresponding to spectral features and intensity of the light, and/or temperature, and/or wind speed, and/or humidity of the environment, and/or the amount and/or type of allergens and/or pollutants contained in the environment, and/or indicator of the location of the person, and/or the place of carrying out the activity; and
determining a most adapted visual behavior of the person to the activity based on the recorded values and the environment data, wherein
the receiving of the person visual behavior data comprises receiving the person visual behavior data from a head mounted device that measures at least part of the person visual behavior data.

7. The method according to claim 6 , further comprising:
receiving head movement data indicative of a head movement of the person, and
determining a most adapted head movement of the person to the activity based on the recorded values.

8. The method according to claim 6 , further comprising receiving physiological data indicative of at least one parameter of a physiology of the person, wherein determining the most adapted visual behavior of the person to the activity is based on the physiological data.

9. A system for monitoring the visual behavior of a person, comprising:
a memory; and
a processor configured to execute program instructions stored in the memory to:
receive person activity data indicative of an activity of the person;
receive person visual behavior data indicative of a visual behavior of the person related to said activity of the person;
receive reference visual behavior data indicative of a reference visual behavior of the person based on said activity of the person;
compare the person visual behavior data and the reference visual behavior data to deduce whether the person visual behavior is adapted for said activity of the person, wherein
receiving of the person visual behavior data comprises receiving the person visual behavior data from a head mounted device that measures at least part of the person visual behavior data.

10. The system according to claim 9 , wherein
the processor is further configured to execute the program instructions stored in the memory to receive environment data indicative of the environment of the person.

11. The system according to claim 9 , wherein
the processor is further configured to execute the program instructions stored in the memory to:
receive head movement data indicative of a head movement of the person from the head mounted device;
receive reference head movement data indicative of the head movement data based on said activity; and
compare the person head movement data and the reference head movement data to determine whether the head movement of the person corresponds to the reference head movement given the current activity of the person.

12. The system according to claim 10 , wherein
the environment data relate to spectral features and intensity of the light received by the person.

13. The system according to claim 9 , wherein
the processor is further configured to execute the program instructions stored in the memory to receive physiological data indicative of at least one parameter of the physiology of the person.

14. The system according to claim 13 , wherein
the reference visual behavior data are provided based the physiology data.

15. The system according to claim 9 , wherein
the activity of the person comprises driving.

16. The system according to claim 15 , wherein
the processor is further configured to execute the program instructions stored in the memory to receive driving condition data indicative of driving conditions.
