Touch screens on museum exhibits

[gatepc]

I have been put in charge of helping redesign parts of a museum. Its a volunteered job but I ran the idea at them of using a touch screen to display information as well as pictures and videos etc. I don't know what kind of computers they have for me to use yet but they are probably windows. So heres my question will a usb touch screen work just like a mouse? is it plug in play? I plan to develop something by scanning in the images and putting the videos and text documents in ether a flash program or just standard html web page that will live on the desktop. It will be used by small children to elderly people and everything in between. It is a small museum and it does not need anything fancy, also they are on a budget. Will these monitors serve that purpose?

Which one would you choose? I don't know much about touchscreen. I think the flat screens would be much better choice for us since it will likely be screwed into counter top or cabinet of some kind.

From my experience with touchscreen displays; when you touch them it's the same as clicking in that spot (and holding until you let go). I'm not sure how others might work though - I had to design something for touchscreen displays at a museum whilst at university.

Does the 5 wire touchscreen technology in those displays allow for me to do things like say scroll up and down? ( I mean after I have already touched the screen if i start moving my finger does it follow? or stay at the spot I originally touched? )
