Hybrid see through augmented reality systems and methods for low vision users
Provided herein are augmented reality visual aid systems, software, and methods which enhance vision, to simulate natural vision, by utilizing hybrid see through occlusion enabled hardware, and software through image manipulation, reprocessing, blending, for presentation and display to the eyes thus enabling a range of tasks previously lost or impacted.
1. A hybrid see-through augmented reality system, comprising: a frame configured to be worn on the head of a user; a camera configured to generate unprocessed real-time video images; a processor configured to apply image processing to the real-time video images from the camera to produce an enhanced video stream; and a first display disposed within the frame and including a first barrier configured to block at least 90% of external light corresponding to a central portion of the user's field of view from entering a first eye of the user while allowing external light corresponding to a peripheral portion of the user's field of view to enter the first eye of the user, the first display being configured to present the enhanced video stream to the central portion of the user's field of view while allowing the enhanced video stream to blend smoothly into the peripheral portion of the user's field of view that comprises the user's natural peripheral vision, wherein the enhanced video stream is magnified in a central portion of the enhanced video stream when compared to the unprocessed real-time video images.
2. The system of claim 1 , wherein the processor is further configured to gradually reduce the imaging processing towards the edges of the enhanced video stream.
3. The system of claim 1 , further comprising a second display disposed within the frame and including a second barrier configured to substantially prevent external light corresponding to the central portion of the user's field of view from entering a second eye of the user while allowing external light corresponding to the peripheral portion of the user's field of view to enter the second eye of the user.
4. The system of claim 3 , wherein the processor is also configured to display the video stream on the second display.
5. The system of claim 1 , wherein a portion of the enhanced video stream outside of the central portion is magnified less than the central portion but more than the unprocessed real-time video images.
6. The system of claim 1 , wherein the processor is configured to process the unprocessed real-time video images to blend a top edge, a bottom edge, a left edge, and a right edge of the video stream with the peripheral portion of the user's field of view.
7. The system of claim 1 , wherein the processor is configured to process the unprocessed real-time video images to blend only a left edge and a right edge of the video stream with the peripheral portion of the user's field of view.
8. The system of claim 1 , wherein the processor is configured to process the unprocessed real-time video with image coordinate remapping to blend the video stream with the peripheral portion of the user's field of view.
9. The system of claim 8 , wherein the image coordinate remapping comprises radial mapping.
10. The system of claim 1 , further comprising an input device configured to receive an input from the user regarding a type and/or an amount of enhancement to apply to the unprocessed real-time video images.
11. The system of claim 10 , wherein the input device comprises a physical mechanism.
12. The system of claim 10 , wherein the input device comprises a microphone configured to receive voice commands from the user.
13. The system of claim 1 , wherein the first barrier comprises a physical barrier disposed on the hybrid see-through augmented reality device.
14. The system of claim 13 , wherein the physical barrier is attached to a lens within the frame.
15. The system of claim 13 , wherein the physical barrier is attached to an outside surface of the first display.
16. The system of claim 13 , wherein the physical barrier comprises an opaque section of a lens disposed within the frame.
17. The system of claim 13 , wherein the physical barrier comprises a material selected from the group consisting of vinyl, tape, paint, ink, silkscreen, paper, metal, and plastic.
18. The system of claim 1 , wherein the first barrier comprises a polarized liquid crystal configured to manipulated to customize specific boundaries between transparent and blocked regions.
19. The system of claim 18 , wherein the polarized liquid crystal encompasses an entirety of the user's field of view.
20. The system of claim 1 , wherein the first barrier comprises a gradual transition from a highest opacity at a center of the first barrier to a lower opacity near edges of the first barrier.
21. The system of claim 1 , wherein the camera is disposed in the frame.
22. The system of claim 1 , wherein the camera is disposed in a device separate from the frame.
23. The system of claim 1 , wherein the processor is disposed in the frame.
24. The system of claim 1 , wherein the processor is disposed in a device separate from the frame.
