The document details the innovative approach of Eyeway in developing augmented reality (AR) technology, emphasizing the challenges of creating realistic and efficient AR experiences. Key features include eye-tracking, foveated projection, and direct retinal projection, which together enhance image resolution and energy efficiency. Eyeway's system aims to provide a high fidelity visual experience that seamlessly integrates with the user's natural vision while improving performance over existing AR devices.

- 13. Company Confidential 13 EyeWay Approach A Combined Approach Eye-Tracking Accurate, high-speed eye-tracking using IR lasers that directs the projection according to the users’ gaze. Foveated Projection An image is projected at the eye’s natural resolution only where it is needed at the center of the field of view. Direct Retinal Projection Low-power lasers project a single pixel at a time directly onto the users' retina without the use of screens or other intermediary images, at any level of brightness and contrast.
- 14. Company Confidential 14 Direct Retinal Projection
- 15. Company Confidential 15 Eye Tracking EyeWay's system utilizes infrared light scattered from the retina (which back illuminates the pupil), and the reflection from the cornea. This method allows EyeWay to track gaze direction by following the optical axis of the eye.

- 21. Company Confidential 21 Matching the fidelity of human vision is complex.
- 22. Company Confidential 22 HDR High Dynamic Range Reality has a much wider range of brightness than current screens can display: Brightness range of flower below: 188 nits to 14,700 nits Current TV and Blu-ray standards: 0.117 nits to 1000 nits
- 23. Company Confidential 23 Preferred Brightness Levels
- 24. Company Confidential 24 Perceptual Quantizer With lasers, the EyeWay system provides a dynamic range equivalent to the desired PQ EOTF standard.
- 25. Company Confidential 25 Wide Color Gamut The CIE Chromaticity Diagram visualizes how much of the human visual range is covered by a particular color gamut Pointer’s Gamut describes the range of colors we encounter in nature HDTV color gamut – Rec 709, aka SDR UHDTV color gamut – Rec 2020, aka HDR: this is the emerging standard set to replace HDTV. However, no existing system currently supports this color gamut. EyeWay technology fully supports HDR, and is even capable of extending it.
- 26. Company Confidential 26 Wide Color Gamut 2D color gamut diagrams represent the colors displayable by a device at a single brightness level
- 27. Company Confidential 27 The EyeWay system supports the UHDTV color gamut across all brightness level
- 28. Company Confidential 28 Laser projection decouples brightness and contrast. This allows our system to present more perceptible details in shadows and highlights, thus better matching the human visual system.
- 29. Company Confidential 29 UHR Ultra High Resolution In order to achieve ultra high resolution, screen-based AR HMDs need to increase pixel density per screen per eye over the whole display area, which increases the overall computing power necessary to run the device and requires complex engineering solutions to embed all these pixels into a small-sized display.
- 30. Company Confidential 30 Foveation The EyeWay system takes advantage of the eye's natural peripheral and foveal vision and addresses these areas separately. When projected into the fovea at 1 pixel per arcmin (or 60 pixels/degree), the eye will perceive a pixel-less, "natural resolution" image. Using this method of projecting 2 SVGA images per eye, the EyeWay system achieves the equivalence of 8K projectors per eye, and is thus 50 times more efficient.
- 31. Company Confidential 31 Vergence Accommodation Conflict When viewing objects naturally in the real world, vergence and focal distances are nearly always identical. When viewing in stereoscopic display, binocular disparity stimulates changes in vergence while the focal distance remains fixed at the display distance, resulting in discomfort as the viewer attempts to adjust vergence and accommodation appropriately.
- 32. Company Confidential 32 3D Accommodation Challenges It is a technological challenge for display-based HMDs to change their focal distance in real time. Light field technology compromises between the number of focal planes and the resolution. Varifocal representation requires good eye tracking system to know exactly where the person is looking Realistic AR requires virtual objects to blend seamlessly into our real environment, which means AR HMDs should present images with accurate stereo disparity and focal distance. It is challenging for display-based HMDs to change their focal distance in real time.
- 33. Company Confidential 33 The EyeWay system solves these challenges by tracking the user’s focus and adjusting the focal plane through changes in laser divergence.
- 35. Company Confidential 35 Energy efficiency is critical to all-day use.
- 36. Company Confidential 36 In order to maintain a large and persistent FOV in screen-based AR HMDs, screens need to output more light over a wider area to ensure light rays enter the eye wherever it looks. This inevitably results in wasted energy, as not all light rays can enter the eye at any given point in time.
- 37. Company Confidential 37 The EyeWay system instantaneously steers a small eye box according to the user’s gaze, thus making the system 80 times more energy efficient than current state of the art AR HMD systems.
