Abstract

A frame for a head mounted device including: a front part; a first temple configured to be electronically connected to the front part via a first connection and including a battery providing electrical power arranged in a cavity in the first temple and connected electrically to the first connection; a second temple configured to be electrically connected to the front part and having a cavity therein configured to receive therein at least one electronic module; and a second connection configured to connect electrically the battery of the first temple to the at least one electronic module of the second temple via the front part to receive power therefrom.

First claim

The invention claimed is:

1. A frame for a head mounted device comprising:
a front part;
a first temple configured to be electronically connected to the front part via a first connection means and comprising battery means for providing electrical power arranged in a cavity in the first temple and connected electrically to the first connection means;
a second temple configured to be electrically connected to the front part and including a cavity therein configured to receive therein at least one electronic module;
second connection means configured to connect electrically the battery means of the first temple to the at least one electronic module of the second temple via the front part to receive power therefrom; and
a wireless battery charging module arranged in at least one of the first temple or the second temple and configured to charge the battery means wirelessly, the wireless battery charging module being configured to connect to a data bus of the frame and to be controlled by a processor of the frame, wherein
at least one of the electronic module, a supplementary electronic module, a complementary electronic module, and an additional electronic module comprises a sensor configured to sense at least one data relating to a user of the frame when the user is using the frame, the at least one data relating at least to one user physiological parameter,
at least one electronic module comprises an information data generating unit configured to provide a recommendation data based on at least one data measured by the sensor of the frame,
the recommendation data is a lens design recommendation, the recommendation data including an activation of at least another electronic module of the frame, and
the front part comprises the complementary electronic module and a lens frame configured to receive an active lens and to position the active lens in front of an eye of a user of the head mounted device when the user wears the head mounted device, the complementary electronic module comprises an optical function controller configured to control an optical function of the active lens.

2. The frame according to claim 1 , wherein the complementary electronic module is configured to be electrically connected to the battery means.

3. The frame according to claim 1 , wherein one of the first temple or the second temple comprises a body and a tip configured to be attached to the body of the temple and including a cavity therein configured to removably receive therein the additional electronic module, the temple comprises third connection means configured to attach the tip to the body of the temple and to connect electrically the battery means of the first temple to the additional electronic module of the tip to receive power therefrom.

4. The frame according to claim 3 , wherein the tip is removably attached to the temple.

5. The frame according to claim 1 , wherein at least one of the connection means comprises a data bus configured to transfer data between at least two electronic modules.

6. The frame according to claim 1 , wherein at least one of the front part, the first temple, or the second temple comprises a processor configured to control at least an electronic module of the front part and/or the first temple and/or the second temple.

7. The frame according to claim 2 , wherein the at least one electronic module and/or the supplementary electronic module and/or the complementary electronic module and/or the additional electronic module comprises a data storage for storing data received from at least one sensor and/or received from a distant unit.

8. The frame according to claim 3 ,
wherein the front part comprises a lens frame configured to receive a lens and to position the lens in front of a user of the head mounted device when the user wears the head mounted device, the complementary electronic module comprises at least a display device configured to display a virtual image towards an eye of the user.

9. The frame according to claim 8 , wherein the at least one complementary electronic module comprises at least a camera configured to acquire images of an environment of the user and the display device is configured to display to the virtual image in addition to a real scene seen through the lens, the virtual image depending on the images acquired by the camera.

10. The head mounted device comprising the frame according to claim 1 .

11. The frame according to claim 1 , wherein the front part comprises active lenses being electrochromic lenses whose opacity is controlled based on luminosity of an environment.

12. The frame according to claim 1 , wherein the electronic module and/or the supplementary electronic module and/or the complementary electronic module and/or the additional electronic module comprises a communication unit associated with the at least one sensor and configured to communicate the data to a unit and/or another electronic module of the frame.

13. The frame according to claim 12 , wherein the another electronic module of the frame configured to be activated by the recommendation data comprises a vibrator module configured to emit a mechanical vibration when the vibrator module is activated.

14. The frame according to claim 12 , wherein the sensor is configured to measure at least one user environment parameter and/or at least one user physiological parameter and/or at least one user visual behavior parameter.

15. The frame according to claim 14 , wherein the environment parameter is light composition.

16. The frame according to claim 14 , wherein the environment parameter is spectral composition of natural light.

17. The frame according to claim 14 , wherein the environment parameter is time of exposure to artificial light.

18. The frame according to claim 14 , wherein the environment parameter is time spent using a display.

19. A frame for a head mounted device comprising:
a first temple configured to be electronically connected to a front part of the frame via a first connector and comprising a power source configured to provide electrical power arranged in a cavity in the first temple and connected electrically to the first connector;
a second temple configured to be electrically connected to the front part and including a second connector and a cavity configured to receive therein an electronic device; and
a wireless charger arranged in at least one of the first temple or the second temple and configured to charge the power source wirelessly, the wireless charger being configured to connect to a data bus of the frame and to be controlled by a processor of the frame, wherein
the second connector is configured to connect electrically the power source of the first temple to the electronic device of the second temple via the front part to receive power therefrom,
at least one of the electronic device and another electronic device comprises a sensor configured to sense at least one data relating to a user of the frame when the user is using the frame, the at least one data relating at least to one user physiological parameter,
at least one of the electronic device and another electronic device comprises circuitry configured to provide a recommendation data based on at least one data measured by the sensor of the frame,
