Challenge I
Vision Overview
For AR to succeed commercially it must be usable (lightweight,
portable, etc.)
Challenge II
AR must provide a realistic image that matches the way we see the
real world

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.

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.

Technical Details

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

Preferred Brightness Levels

Perceptual
Quantizer
With lasers, the
EyeWay system
provides a dynamic
range equivalent to
the desired PQ
EOTF standard.

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.

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.
