Head Tracking with Manual Switch Activation
You can use a switch with head tracking. Use head tracking to move the
cursor and use the switch to make activations. This feature is activated
when you connect a switch to your device.
Important!
This feature works well for making selections in
vocabularies, but it does not allow you to make selections from menus.
Use head tracking to make menu selections.
1.
Set up the switch you want to use.
If you are using a wired switch:
Connect the switch to either port A
or port B.
If you are using a wireless Bluetooth switch:
Pair the wireless switch
with your device. See the instructions that came with your switch.
2.
Set the dwell time high enough to avoid accidental activations with
head tracking. Choose
Menu
>
Settings
>
Input
>
Head Tracking
>
Dwell Time
.
Hint:
Experiment with a time that works best for you. You might
want to start with a long dwell time such as 10.0 seconds and see if
you can work your way down to a lower setting and still avoid
accidental activations with head tracking.
