Abstract
Eyewear including an optical element, a controller, a support structure configured to support the optical element and the controller, light sources coupled to the controller and supported by the support structure, and a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern or a prism-like diffusion pattern.
Claims20
Eyewear comprising:
- a controller;
- lenses;
- a support structure configured to be worn on a head of a user and to support the controller and the lenses;
- a light source coupled to the controller and supported by the support structure, the light source controlled by the controller based on a lighting pattern selected by the user to indicate at least one of whether images are being recorded, whether video is being recorded, or whether sound is being recorded;
- and
- a light diffuser on a surface of the support structure, the light diffuser positioned to diffuse light emitted by the light source using microstructures to direct light having the lighting pattern toward at least one of an eye of the user or towards an observer in proximity of the user.
3 more elements
An eyewear control method for illuminating eyewear to be worn by a user, the method comprising:
- detecting, by a controller in a support structure of the eyewear, a trigger signal instructing the controller to illuminate at least one light source coupled to the controller and supported by the support structure to output a lighting pattern selected by the user to indicate at least one of whether images are being recorded, whether video is being recorded, or whether sound is being recorded;
- and
- in response to receiving the trigger signal, illuminating, by the controller, the at least one light source in the support structure such that the at least one light source emits light through a light diffuser on a surface of the support structure, the light diffuser positioned to diffuse light emitted by the at least one light source using microstructures and to direct light having the lighting pattern selected by the user toward at least one of an eye of the user or towards and observer in proximity of the user.
