The EyeMobile Plus is designed to work optimally when it is parallel to the user’s eyes at a distance from about
45 — 85 cm (18 to 33 inches).
This means that for those users leaning sideways or those lying down, the EyeMobile Plus also needs to be tilted in order to keep
the users eyes parallel to the screen and at the optimal distance.
The optimal distance that a user should be from the EyeMobile Plus mounted on a monitor/laptop differs depends on the size
of the screen. The user should be positioned at the optimal distance to allow for the best possible Windows Control.
Generally, the larger the size of the screen, the greater the distance the user should be from the Eye Tracker / Screen combination
for optimal Tobii Dynavox Windows Control usage.
