Using Communication Device

We are teaching Emily to user her new communication device. I thought you all might like this video. She is doing so great with it. The green lights on the bottom of the device show that the camera sees her eyes, and all she has to do is look at something to "mouse click" it. Right now she has just 6 squares on each page. When she gets more proficient with the device she will be able to work with more squares (12, 24, etc). Right now I am trying to teach her about hitting the back button so she can choose a different page/screen to talk about different things.
