Using IntelliGaze™ IntelliGaze™ Installation & Service Manual

WARNING - If the IntelliGaze product is mounted in such a way to a

monitor that it may fall and potentially harm the user, this is done solely

at the user’s own risk. alea technologies or any of its representatives do

not take any responsibility and will not be liable for any damages or

injuries arising from the product falling onto someone or something, even

if the mounting has been made according to instructions.

As a general rule, the user should be centered in-front of the screen in a normal working position,

whenever possible. If the system will be mounted above a bed, or the users head has been stabilized

in a slightly tilted position, please adjust the monitor accordingly as pictured below.

5.3 Special Cases

IntelliGaze™ is designed to work out of the box for the majority of users without adjusting any parame-

ter. Some parameters allow users to adopt the system to special cases. The following overview explains

which parameters should be used in which situation.

5.3.1 Glasses

Most glasses do not interfere with the system, but bifocals and multifocals can be problematic.

If calibrating a subject wearing glasses continuously gives you an inaccurate calibration, you should

first try to change the camera position and repeat the calibration. Very often some disturbance reflec-

tion on the glasses will disappear if you change the system geometry. The eye video window will help

you to find good positions for the camera. Ctrl + F10 toggles the head status window into an eye video

if this option is activated in the IntelliGaze™ service mode.

In rare cases, the accuracy will be decreased when using IntelliGaze™ with glasses. You should increase

the cell size of your communication software in this case.

Sometimes when working with glasses, a limited area of the screen cannot be calibrated and used. Try

to change the calibration area (center, bottom, full) and avoid putting AAC input functions in the prob-

lematic area.

5.3.2 Monocular Operation

When just one eye of the subject is visible you should select “left or right eye calibration” and check the

option “ignore the other eye completely”. When just one properly moving eye is available because the

other eye is a glass eye or is visually impaired, you should NOT check the option “ignore the other eye

completely”. Both eyes are used for tracking but only the good one is used for calibration.

In monocular operation mode the accuracy can be decreased. Make sure that the cells of your commu-

nication software are large enough to cover this inaccuracy.
