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.
