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?

Next, what about the computer? I thought about something like Hummingbird i2 or Cubox-i4Pro so it would support at least OpenGL 2.0, Wi-Fi adapter, keyboard and all those things and which would be ready to install the OS on it. Also it needs to be compatible with the chosen touchscreen.

For now that's all I have on my mind, I'll add more questions later if needed. I'm open for suggestions!

In the spirit of "DoTheSimplestThingThatCanPossiblyWork" don't try and reinvent the wheel here.

Run with some easily commercially available and stable platform (EG iPad is a fairly universal thing, decent build quality, known form factor, etc.) as your job is not to invent some new hardware platform but to make a kiosk that presents some content. You cannot make a small-volume touchscreen kiosk device for less money than Apple of Samsung can sell you a tablet or even full blown laptop or desktop computer, and you will waste huge amounts of time & money trying (and no-one will thank you or pay you more for doing so).

Doing it in a web browser (HTML + JS + video) locked in kiosk mode means your software/content, such as it is, can transfer to almost any other device with little effort.

Edit to add: Because it's relevant, and because he's a hero, check out Tim Hunkin's website, he's made all manner of interactive kiosks, displays, and arcade machines and has some good insights. My favourite being the dog walking simulator.
