Goggles, system and method for providing feedback

1. Goggles, configured for an exercise activity, for providing feedback to a user, the goggles comprising:

a lens;

a display comprising:

a first surface of the display being arranged to continuously cover all of a first surface of the lens in order to uniformly distribute light across all of the first surface of the lens;

a second surface of the display being exposed; and

a light guide to render light signals;

a light source coupled to the display to generate signals to the display corresponding to the light signals to be displayed, wherein the display is at least partially formed of a frame or frame connection connected to the lens, the frame and/or the frame connection being formed at least partially of a transparent material; and

at least one outcoupling structure located at the display to scatter the light signals.

2. The goggles as claimed in claim 1 , wherein the at least one outcoupling structure is formed on the light guide such that the light signals are enabled to exit the light guide through the at least one outcoupling structure.

3. The goggles as claimed in claim 1 , wherein the light guide comprises an at least partially reflective portion or an at least partially diffusely reflective portion for reflecting and/or scattering the light of the light source.

4. The goggles as claimed in claim 1 , wherein the at least one outcoupling structure is formed at either the first or second surface and/or in a bulk of the lens.

5. The goggles as claimed in claim 1 , further comprising an energy supply to provide electrical power, a receiver configured to obtain electrical power via contactless energy transfer and/or a kinetic energy convertor to convert movements of the goggles into electrical power.

6. The goggles as claimed in claim 1 , further comprising a sensor to sense physical or physiological parameters of a user and/or physical parameters of an environment of the user.

7. The goggles as claimed in claim 6 , wherein said sensor is further configured to:

measure a stroke frequency of the user, time, efficiency, depths, heartbeat, hip rotation or hip orientation;

measure an acceleration and/or movement of the goggles;

determine the orientation of a head of the user; and

measure a direction of movement of the user.

8. The goggles as claimed in claim 6 , wherein said sensor is integrated in the frame or a strap of the goggles which is connected to the frame.

9. The goggles as claimed in claim 1 , wherein the display comprises a liquid including charged, colored particles for changing a transparency and/or the color of the display.

10. The goggles as claimed in claim 1 , further comprising at least one receiver to acquire signals to be displayed.

11. A system for providing feedback to a user, comprising:

a feedback system configured to provide a feedback signal;

a transmitter coupled to the feedback system, the transmitter being configured to communicate the feedback signal to a receiver coupled to goggles for an exercise activity, the goggles comprising:

a lens;

a display comprising:

a first surface of the display being arranged to continuously cover all of a first surface of the lens in order to uniformly distribute light across all of the first surface of the lens;

a second surface of the display being exposed; and

a light guide to render light signals;

a light source coupled to the display or the lens for providing signals to the display corresponding to the light signals to be rendered, wherein the display is at least partially formed of a frame or frame connection, the frame and/or the frame connection being formed at least partially of a transparent material; and

at least one outcoupling structure located at the display to scatter the light signals.

12. The system as claimed in claim 11 , wherein the feedback system further comprises at least one sensor to determine at least one physical and/or physiological parameter of the user.

13. A method for providing feedback to a user, comprising:

determining at least one physical and/or physiological parameter of the user;

generating a feedback signal based at least partially on the at least one physical and/or physiological parameter;

providing the feedback using goggles for an exercise activity, the goggles comprising:

a lens;

a display comprising:

a light guide for rendering light signals;

a first surface of the display being arranged to continuously cover all of a first surface of the lens in order to uniformly distribute light across all of the first surface of the lens;

a second surface of the display being exposed;

a light source coupled to the display for providing signals to the display corresponding to the light signals to be displayed, wherein the display is at least partially formed of a frame or frame connection, the frame and/or the frame connection being formed at least partially of a transparent material; and

at least one outcoupling structure located at the display to scatter the light signals.

14. Goggles, for an exercise activity, for providing feedback to a user, the goggles comprising:

a lens;

a display comprising a light guide to render light signals;

at least one outcoupling structure located at the display to scatter the light signals; and

a light source coupled to the display, the light source to generate signals to the display corresponding to the light signals to be displayed, wherein the display is formed of a continuously at least partially transparent element, a first surface of the display being continuously attached to all of the first surface of the lens in order to uniformly distribute light across all of the first surface of the lens, wherein a second surface of the display is exposed, and wherein a transparency and/or color of the display are adaptable electrically using the signals provided by the light source.
