Head Tracking Tips
Pausing Head Tracking
When you turn head tracking on, “Pause” appears centered between Vocab and Menu. When you
activate Pause, head tracking stops temporary and “Resume” appears. Use your trigger action to
activate Resume and start up head tracking again.
Important!
Currently “Resume” does not work with the Hover trigger action. Do not attempt to pause
head tracking when the trigger action is set to Hover.
Scrolling
When head tracking is enabled, quick scroll arrows appear in the corners of the TouchChat settings and
the TouchChat list of vocabularies. When you need to scroll through these lists of items, point at and
trigger the appropriate quick scroll arrow.
