5.1
Positioning the User
Figure 5.1 Positioning
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), see
Figure 5.1 Positioning, page 13
or
Figure 5.2 Positioning for Users Leaning Sideways or
Lying Down, page 13
.
Figure 5.2 Positioning for Users Leaning Sideways or Lying Down
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, see
Figure 5.2 Positioning for Users Leaning Sideways or Ly-
ing Down, page 13
.
Make sure the user is placed comfortably in relation to the optimal positioning of, and distance from, the unit. Be
aware also that the user’s comfort, as well as the Windows Control performance, will be enhanced if the sun is not
shining directly on the screen or into the user’s eyes.
The optimal distance that a user should be from the EyeMobile Plus mounted on a monitor/laptop differs depending 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 combina-
tion for optimal Tobii Dynavox Windows Control usage.
Monitors larger than up to the maximum screen size limitation should not be used for optimal Tobii Dynavox Windows Control
usage, for more information see
Appendix C Technical Specifications, page 20
