Communicating Through the Seeing Eye Gaze Device- Tobii Dynavox

We use the Tobii Dynavox (a seeing eye gaze device) to communicate. The seeing eye gaze device works by tracking her eyesight. It can be difficult for Ariana to use at times because she can't look up or down due a mid dorsal brain bleed at birth that caused vertical gaze palsy, and her lack of head control. We like to use the Tobii in the both the sitting and standing position.
