Appendix D: Positioning Examples
When positioning is correct, the device and the client’s face will be on the same plane—basically parallel
to each other. The track box will always show two white circles next to each other near the center of the
box. The client’s eyes will be within 18” – 30” of the display.
Correct Positioning from the side and as seen straight on.
Eyes are level and gaze is in the middle-to-upper part of the display.
With correct positioning, the nose should be pointed at the vertical middle of the display and the eyes
should be looking in the middle to the top two-thirds of the display. To achieve correct positioning you
may need to move your device, the client, or both until the client is comfortable and the white ovals line
up in the track box.
