Sarah has multiple disabilities from stroke. This video shows her using a Quick Glance system (with The Grid software; Dynavox 5 Software and Boardmaker SDP also available on the Quick Glance/Eye Tech SGD) to communicate. The device shown is now available smaller and with more portability. However the device costs about the same as a Dynavox or PRC plus the cost of the eye gaze controller which is slightly more than the device itself. Let's hope these prices come down!
Jenna has Spinal Muscular Atrophy. This video shows her using the Quick Glance 3 by Eye Tech to paint a picture using eye movement only. You can't see Jenna, but you can see her paint and hear her mom chat with her. Very cool.

Please note that the Quick Glance eye gaze controller cannot be added to any current AAC device on the market. The competitor to the Quick Glance is the Tobii, but it does not allow the head and body movements that the Quick Glance does and does not interact with off the shelf software as well as the Quick Glance. (I know because I have tried them both.)
