Eyegaze Edge User manual

With a little practice, you will learn to position the Eyegaze Edge®correctly
for successful calibration. There are a few reminders to have a successful
experience:
•Watch the Eyegaze Edge®set-up video on the desktop of the device
for review.
•Positioning the person & the device
1. position the individual comfortably
2. Position the screen between 18-30 inches away from their face.
3. Ensure that the plane of the screen is parallel to the plane of the
user’s face. If the person is reclined or laying down, position the
screen to be parallel to the recline angle.
4. Find the person’s eye using the eye image on the screen.
Position the person first, then the screen of the device, then the
camera.
5. Gently rotate the camera lens clockwise or counter clockwise until
you obtain a clear eye image on the screen. When it stops
rotating in either direction do not continue rotating.
•Use the on-screen eye image to guide you. This image tells us if the
position is correct and allows us to see the user’s eye clearly during
use.
Positioning the
Eyegaze Edge®
With the C6 Camera
A focused eye image should be crisp and clear
like the image here. If not, make adjustments by
rotating the camera lens to get a clear image
----------------------------------------------
The eye is in the center of the right box
The focus indicator is present and positioned in the
center of the left and right eye images
The left image shows a clear pupil without spots
There is a tracking gnat in the center of the pupil
The glint spot of light is visible on the cornea

When you get stuck during the calibration process, it is a great time to
exercise critical thinking skills about what might be wrong. Instead of
getting frustrated, ask yourself, “what else can I change to possibly get a
different outcome?” Start by trying these tips to get an accurate calibration
(less than 0.5 inches).
•Try the other eye. Sometimes the camera will track one eye better
than the other.
•Change the position of the Eyegaze Edge
®slightly: move it up or
down, backward or forward, left or right, or change the angle slightly.
Sometimes this slight change in position will help.
•Observe the environmental light and change if you see a glare on the
user’s glasses. Make sure the glasses are clean.
•Evaluate whether or not their eyes are dry: is it later in the day? Is
there a glint spot on the cornea? Is the eye image on the screen
inconsistent? Use eye drops if needed.
•Skip a calibration point if needed (hit Fn + F2 on your keyboard) to
avoid frustration.
•Pull up the calibration shortcut menu (Ctrl + C) and change from 9
calibration points to 5 points, or change from a small calibration point
to a larger one. Remember that we start with 9 small yellow balls, and
then move to fewer and bigger targets only as needed.
•If the person has difficulty focusing on the calibration point, give a
verbal cue and point to it with your finger.
•If all else fails, connect the device to the internet and phone LC’s
technical team for remote support (1-800-EYEGAZE). LC’s technical
team will see the eye image and coach you through calibration.
•After calibration, a flash of calibration numbers will appear on the
screen. To pause this display, simply press the space bar on the
keyboard.
•Want to start calibration over again? Hit Fn + F1 on the keyboard.
•Want to exit the calibration screen? Hit ESC on the keyboard.
