I am a speech pathologist and use communication devices with my students on a regular basis. the basic concept is that you have a screen with a given set of buttons on it that, when pressed, gives a voice output response. For example, a picture of a drink and you push it and it says (through the ext speaker) "I want a drink of water."
I would like to figure out if this is a possible use for the tablet. Here is what I need help figuring out.
1. Can I divide the screen into 8-10 "button" zones.
2. Can I add picture images and text to those zones
3. Can I make a button press that causes a voice response. (could play a recoprding of the desired message or use voice generation if availible.)
In a perfect setup I would like to be able to make buttons that switch back and forth between screens (ie - a screen of different food choices that could be accessed by pushing a main screen food button)

I have absolutely no programming knowledge, but am hoping there is some program out there that I can adapt in some way to be able to do this. A dynamic display device like this could easily cost thousands of dollars, which makes them unrealistic for most families. This could revolutionize the communication abilities of many children.

Anyone interesed?
