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.
