Augmented reality glasses
The invention describes augmented reality glasses comprising a frame which supports a glasses lens, wherein associated with the frame are a miniaturized display configured for emitting images in a predetermined direction, an optical system configured for receiving the images coming from the display and creating processed images, and reflection means configured for receiving the processed images and reflecting them towards the glasses lens, so as to project the processed image onto this lens, wherein this lens is configured for reflecting the projected image in a direction of the ocular axis.
1. Augmented reality glasses comprising:
a frame which supports a glasses lens and is completed by two supporting temples of the glasses, wherein said lens comprises a flat lens comprising in its turn two lenses coupled so that one of respective coupling faces is treated with a reflective coating;
wherein said frame is associated with:
a miniaturized display configured for emitting images away from a plane comprising the longitudinal extension of the glasses lens and in a direction which substantially coincides with the directrix of a supporting temple in the prevalent direction of extension of the supporting temple;
an optical system configured for:
receiving images from said display;
processing said images so as to create processed images;
addressing these processed images in said direction away from said plane comprising the longitudinal extension of the glasses lens;
reflection means configured for receiving said processed images and reflecting them at a first predefined angle towards said glasses lens, so as to project said processed image onto said glasses lens, thereby defining a projected image;
wherein the lens is made to reflect the image coming from the display so that the centre of this image is at the centre of the glasses lens and is reflected along the ocular axis, enabling the eye to perceive it at the centre of the observed scene;
said at least one lens being configured for reflecting said projected image in a direction of the ocular axis according to a second predefined angle with respect to the direction of incidence of said processed images onto said glasses lens.
2. The glasses according to claim 1 wherein said display is a transmissive display.
3. The glasses according to claim 2 comprising an LED configured for back-lighting said display.
4. The glasses according to claim 1 wherein said display is a reflection display.
5. The glasses according to claim 4 wherein said optical system is configured for concentrating solar rays onto said display.
6. The glasses according to claim 5 wherein said optical system comprises at least one lens.
7. The glasses according to claim 1 comprising a luminosity sensor configured for measuring values of luminous intensity.
8. The glasses according to claim 1 comprising a processing unit configured for processing input data to said glasses to generate corresponding images on said display.
9. The glasses according to claim 8 wherein said processing unit comprises an adjustment module configured for producing an image for said display as a function of said luminous intensity.
10. The glasses according to claim 9 wherein said processing unit comprises a selection module configured for selecting the display mode of said display as a function of said luminous intensity so as to produce an image for said display as a function of said luminous intensity.
11. The glasses according to claim 1 wherein said lens comprises on a part thereof a surface coating configured to make a part of the glasses lens as an inclined flat mirror.
12. The glasses according to claim 1 wherein said optical system is configured for a variation in the position of its components in order to vary the focal length of the system so as to compensate for the visual defects of the user.
