4 Using PCEye Plus
4.1 Positioning the User
Figure 4.1 Positioning
The mounted PCEye Plus attached to its Magnetic Mounting Plate and to your device is designed to work optimally when it is
parallel to the user’s eyes at a distance from about 50 — 90 cm (20 to 35 inches), see
Figure 4.1 Positioning, page 9 or Figure
4.2 Positioning for Users Leaning Sideways or Lying Down, page 9 .
Figure 4.2 Positioning for Users Leaning Sideways or Lying Down
This means that for those users leaning sideways or those lying down the PCEye Plus with monitor and computer device also
needs to be tilted in order to keep the users eyes parallel to the screen and at the optimal distance, see
Figure 4.2 Positioning
for Users Leaning Sideways or Lying Down, page 9 .
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 PCEye 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 2 usage.
Monitors larger than up to the maximum screen size limitation should not be used for optimal Tobii Dynavox Windows Control 2
usage, for more information see
Appendix C Technical Specifications, page 15 .
