Abstract

A wearing detection module configured to be fixed on a spectacle frame element of a smart spectacle frame, the spectacle frame element including a first surface configured to face the wearer when using the smart spectacle frame and a second surface opposed to the first surface, and the wearing detection module including a pair of sensors configured to measure one parameter indicative of the distance between the spectacle frame element and the wearer, one sensor is arranged on the first surface and the other one is arranged on the second surface, and a processing unit configured to receive data indicative of the parameter sensed by each sensors and to determine a wearing data indicative of the use by the wearer of the smart spectacle frame based on the received data.

First claim

The invention claimed is:

1. A wearing detection module configured to be fixed on a spectacle frame element positioned on one side of a smart spectacle frame, the spectacle frame element comprising a first surface that faces a wearer when using the smart spectacle frame and a second surface opposed to the first surface that does not face the wearer when using the smart spectacle frame, the wearing detection module comprising:
a pair of sensors arranged on opposite surfaces of the spectacle frame element and each configured to measure a distance between the spectacle frame element and the wearer, one sensor is arranged on the first surface of the spectacle frame element that faces the wearer when using the smart spectacle frame and the other sensor is arranged on the second surface of the spectacle frame element that does not face the wearer when using the smart spectacle frame, both sensors positioned on a same side of the wearer's head; and
processing circuitry configured to receive data of the distance sensed by each of the sensors and to determine wearing data indicative of use by the wearer of the smart spectacle frame based on the received data.

2. The wearing detection module according to claim 1 , wherein at least one sensor of the pair of sensors is an infrared proximity sensor configured to emit light and to detect light reflected back.

3. The wearing detection module according to claim 1 , wherein at least one sensor of the pair of sensors is a capacitive sensor configured to measure a contact area or the distance between the spectacle frame element and the wearer.

4. The wearing detection module according to claim 1 , wherein at least one sensor of the pair of sensors is a temperature sensor configured to measure a temperature related to the distance between the spectacle frame element and the wearer.

5. The wearing detection module according to claim 1 , wherein at least one sensor of the pair of sensors is a resistive sensor configured to measure biological and/or physiological parameters of the wearer.

6. The wearing detection module according to claim 1 , wherein the spectacle frame element is a spectacle temple or a spectacle front part of the smart spectacle frame.

7. A spectacle frame element for a smart spectacle frame comprising the wearing detection module according to claim 1 .

8. A head mounted device comprising:
a smart spectacle frame having a spectacle frame element positioned on one side of the smart spectacle frame that includes a first surface that faces a wearer when using the smart spectacle frame and a second surface opposed to the first surface that does not face the wearer when using the smart spectacle frame, the spectacle frame element including a wearing detection module configured to be fixed on the spectacle frame element, the wearing detection module including
a pair of sensors arranged on opposite surfaces of the spectacle frame element and each configured to measure a distance between the spectacle frame element and the wearer, one sensor is arranged on the first surface of the spectacle frame element that faces the wearer when using the smart spectacle frame and the other sensor is arranged on the second surface of the spectacle frame element that does not face the wearer when using the smart spectacle frame, both sensors positioned on a same side of the wearer's head, and
processing circuitry configured to receive data of the distance sensed by each of the sensors and to determine wearing data indicative of use by the wearer of the smart spectacle frame based on the received data.

9. The head mounted device according to claim 8 , further comprising an electronic component and a battery configured to power the electronic component and a managing unit comprising at least:
a non-transitory memory configured to store computer executable instructions, and
a processor for executing the computer executable instructions, wherein the computer executable instructions comprise instructions for managing the power delivered by the battery to the electronic component considering the wearing data determined by the wearing detection module.

10. The head mounted device according to claim 8 , further comprising a communication device and a managing unit comprising at least:
a non-transitory memory configured to store computer executable instructions, and
a processor for executing the computer executable instructions, wherein the computer executable instructions comprise instructions for managing the reception or emission of data by the communication device to another communication entity considering the wearing data determined by the wearing detection module.

11. The head mounted device according to claim 8 , further comprising a health monitoring device configured to be fixed on the spectacle frame, wherein the monitoring device comprises:
at least two light sensors configured to measure light data indicative of at least one parameter of light received by the wearer when the head mounted device is worn by the wearer, and
a communication device associated with the light sensors and configured to communicate said light data to an information data generator,
the information data generator configured to:
receive and store said light data, and
generate light information based on the received light data, the light information being indicative of at least spectrum of the light received by the wearer, intensity of the light received by the wearer, dose of the light received by the wearer.

12. The head mounted device according to claim 11 , wherein the head mounted device further comprises an optical function controller configured to control an optical function of the head-mounted device based on light information generated by the monitoring device.

13. The head mounted device according to claim 8 , further comprising an environmental light monitoring device configured to be fixed on the spectacle frame, wherein the environmental light monitoring device comprises:
a environmental light sensor configured to measure environmental light data indicative of at least one parameter of light in an environment of the head mounted device, and
a communication device associated with the environmental light sensor and configured to communicate said environmental light data to an environmental information data generator,
the information data generator configured to:
receive and store said environmental light data, and
generate environmental light information based on the received environmental light data, the environmental light information being indicative of at least spectrum, intensity, dose of the light in the environment of the head mounted device,

wherein the environmental light monitoring device further comprises a solar cell arranged to receive light and to convert energy of received light into electricity capable to power at least the environmental light sensor, the communication device and the information data generator.

14. The wearing detection module according to claim 1 , wherein the spectacle frame element is a spectacle temple of the smart spectacle frame such that the one sensor is arranged on the first surface of the spectacle temple that faces the wearer when using the smart spectacle frame and the other sensor is arranged on the second surface of the spectacle temple that does not face the wearer when using the smart spectacle frame.
