Abstract

Disclosed is a method implemented with a head-mounted device for identifying a distinct device within a given range distance of the head-mounted device, the head-mounted device includes a receiver adapted to receive wireless signals and a memory adapted to store data. The method includes: a tag data receiving step during which tag data identifying at least one electronic wireless tag placed on the distinct device are received by the receiver of the head-mounted device; a storing step during which the stored data including the tag data are stored in the memory of the head-mounted device; and an identification step during which the device is identified based on the stored data.

First claim

The invention claimed is:

1. A method implemented with a head-mounted device configured to identify a distinct device within a specific range distance of the head-mounted device, the head-mounted device including a receiver configured to receive wireless signals, a memory configured to store data, a function controller configured to control at least one function of the head-mounted device and configured to control at least one controllable active optical lens, the method comprising:
receiving tag data identifying at least one electronic wireless tag placed on the distinct device by the receiver of the head-mounted device;
storing data comprising the tag data in the memory of the head-mounted device as stored data;
identifying the distinct device based on the stored data;
modifying the at least one function of the head-mounted device based on the stored data, the at least one modified function being an optical function of the controllable active optical lens;
determining an activity of a wearer based on the stored data, the determined activity being stored in the memory of the head-mounted device so that the stored data is updated to further comprise activity data; and
determining a determined angle between the head-mounted device and at least two electronic tags placed on the distinct device based on the received tag data, the determined angle being stored in the memory of the head-mounted device, so that the stored data is updated to further comprise the determined angle data,
wherein the at least one modified optical function is an active dioptric function, and
wherein, during the function modifying, the active dioptric function is modified to be adapted to the wearer based on the stored data.

2. The method according to claim 1 , further comprising determining a distance between the head-mounted device and the distinct device based on the received tag data, the determined distance being stored in the memory of the head-mounted device, so that the stored data is updated to further comprise distance data.

3. The method according to claim 1 , further comprising determining another angle between at least two receivers of the head-mounted device and an electronic tag placed on the distinct device based on the received tag data, the determined other angle being stored in the memory of the head-mounted device, so that the stored data is updated to further comprise the other angle data.

4. The method according to claim 3 , further comprising determining a viewing distance of the wearer of the head-mounted device based on the stored data.

5. The method according to claim 1 , further comprising determining a viewing distance of the wearer of the head-mounted device based on the updated stored data.

6. The method according to claim 1 , wherein the modifying the at least one function of the head-mounted device comprises acting on an activation of said function.

7. The method according to claim 1 , wherein the modifying the at least one function of the head-mounted device comprises adapting the function.

8. The method according to claim 1 , wherein the at least one function of the head-mounted device comprises at least one notification function configured to send a notification to the wearer.

9. The method according to claim 1 , wherein the at least one modified optical function is an active transmission function, and
wherein, during the function modifying, the active transmission function is modified based on the stored data.

10. The method according to claim 1 , further comprising processing the stored data to determine at least part of a visual profile of the wearer of the head-mounted device.

11. A head-mounted device comprising:
at least one controllable active lens;
a function controller configured to control at least one function of the head-mounted device;
a receiver configured to receive signals;
a processor; and
a memory configured to store one or more sequences of instructions that are accessible to the processor, and which, when executed by the processor, causes the processor to carry out a method comprising:
receiving tag data identifying an electronic wireless tag placed on a distinct device by the receiver of the head-mounted device,
storing data comprising the tag data in the memory of the head-mounted device as stored data,
identifying the distinct device based on the stored data,
modifying the at least one function of the head-mounted device based on the stored data, the at least one function being an optical function of the controllable active optical lens,
determining an activity of a wearer based on the stored data, the determined activity being stored in the memory of the head-mounted device so that the stored data is updated to further comprise activity data, and
determining a determined angle between the head-mounted device and at least two electronic tags placed on the distinct device based on the received tag data, the determined angle being stored in the memory of the head-mounted device, so that the stored data is updated to further comprise the determined angle data,

wherein the at least one modified optical function is an active dioptric function, and
wherein, during the function modifying, the active dioptric function is modified to be adapted to the wearer based on the updated stored data.

12. A system comprising:
at least an electronic wireless tag, the at least one electronic wireless tag emitting an identifying wireless signal; and
at least the head-mounted device according to claim 11 .

13. The method according to claim 1 , further comprising determining another angle between at least two receivers of the head-mounted device and an electronic tag placed on the distinct device based on the received tag data, the determined other angle being stored in the memory of the head-mounted device, so that the stored data is updated to further comprise the other angle data.
