Thin Film Transistor. Basically what all - or most - modern digital "LCD"
monitors are using.
However, it is not clear from Anne's post whether this is a monitor, 100
monitors, or some other rig.
If it's a monitor then I'm sure there are touchscreens that will fit the
If it is some other rig, she'll probably need to contact the manufacturer to
see what type of signal is sent - to a computer? - to an interface between it
and a computer? Serial Comm Port? USB? Parallel?
Does it emulate a mouse? a keyboard? Simple low-to-high voltage change on a
wire? Is there a software API available - ActiveX? - Xtra?...
In other words, if it's not a monitor, there's not enough information to go

Sounds like 100 touchscreens, each with a different picture, each acting as a single button. When you touch a screen/image/button - 'something happens'.
So for a start, you need 100 computers to feed 100 touchscreens. Each will most likely be running a projector
If the 'something' which happens is contained to the screen that was touched, then the projector can deal with this.
If 'something' is external - for example, a big screen displays the image that was touched, then you need the computers to all be on a network and use MultiUser Server, or Flash Communication Server, some other kind of server side application

I hadn't even considered that possibility. 100 screens scattered about a
trade show, hotel, class room, various locations around the world, etc...
As you suggested, the MultiUser Server/Flash Communication Server concept
would be the way to go.

Thank you very much:
Maybe multiuser Xtras (and server) works for this project
you can probably use two screens per computer of more but youll have to connect them in a local area network in some way and let all applications communicate with eachother. I Suggest you use a flash sprite in your shockwave movie comunnicationg with a socketserver (my experience is thats its faster than the multiuser xtra).
