My goal is to develop an interactive kiosk with only touchscreen available to visitors for a local museum. I must admit that I'm a freshman in this part of hardware world, but I really like the sound of this challenge, so I need to get some info/advice first about kiosk's components.
Regarding to the software part, I'm going to use an Arch Linux OS and develop my own kiosk software for the most minimalistic framework possible. I opt for making an app based on WebGL (because I believe this is my forte), so WebGL Hardware Acceleration must be supported by GPU. In case WebGL would be too heavy, my emergency plan is to build a good HTML site or a standalone Java app (which could be the hardest way, but more efficient).
So now about the hardware: The first thing that interests me the most are touchscreens - is there a special type of them, i.e. industrial ones, that are appropriate for this purpose? Where to find them and which one would you recommend me?
