We would like to make an interactive exhibition piece foolproof, requiring as little staff presence as possible when recovering it from anything anyone made it do.
It has a text input and then it outputs something. I figured the easiest would be to not give them a mouse at all, just a keyboard that is always focused on the single input field. And then disable every shortcut and special key possible, remaining only with letters, space, backspace and enter.
We are flexible in terms of OS and wether the UI is a HTML page or a desktop app. But obviously windows (or a standard linux distro) and a HTML page would be best. We may need GPU drivers for the backend.
Tried googleing around, but maybe I haven't stumbled on the right keywords, because we are not the first ones having this problem. But then again, most interactive exhibits are very poorly secured.
