I've been trying to find more information about eye gazing, and what kind of systems are out there. These are two that my AT specialist is going to let me look at tomorrow. Both are from Austrailia, and are available for purchase in the US.
Look 2 Talk - 80.85 Great British Pounds - $162
Pragmatic Organisation Dynamic Display (PODD) - 250 Austrailian Dollars - $160
Both systems are customizable and also have pre-made boards. I am hoping to find more information tomorrow and will share with you after my look.
