I am looking for an OS that will work on a touch screen display. This is for a kiosk in a customer's store. This could be rolled out to as many as 500 stores and needs to be solid and maintainable.

The OS only has to display a web browser in Full Screen mode and run a few web applications.

The one feature that makes or breaks my decision is how typing into text fields is handled. When a text field gets focus (user touches field) an on-screen keyboard needs to appear. When the field looses focus (user touches something else) the keyboard needs to go away.

I found his thread that suggests Windows 7 but does specify how the on-screen keyboard is opened or closed. On-screen keyboard for touch display

So far I have had a hard time finding concrete information online. It appears that This will not work on Windows 7 or a Linux distribution (please correct me if I am wrong).

I am not sure how I feel about being left with only beta versions of x86 ports of Android or the beta version of Windows 8 (Metro) but those are looking like they might be my only options.

Does anyone have additional information? Has anyone accomplished a solution like this?

UPDATE I forgot that it has been already been decided, by management, that we will be using a 32" touch display for the kiosk.

Windows 7 fully supports the on-screen keyboard, and you can have it enabled by default if you have a touchscreen-compatible display. – Breakthrough Apr 16 '12 at 14:24
@Breakthrough, does this mean it will popup when a field gains focus and hide when it looses focus? This needs to be dead simple. It is for a store kiosk that will have a huge range of people using it. – modernzombie Apr 16 '12 at 14:40
I believe it does, yes. I was at a restaurant the other day with a Windows 7 touch-screen at my table, and every input field I "clicked" brought up the OSK. – Breakthrough Apr 16 '12 at 14:52
@Breakthrough, if it does that will be great. We are ordering the equipment to set up a demi unit and test out OSs. I'll give Windows 7 a try first. Thanks. – modernzombie Apr 16 '12 at 15:00

What do you feel about using iOS on iPads? You can even use the Apple Configurator to disable the home button. You could use something like OpenDNS (or some sort of proxy server) to whitelist only certain websites, or (preferably) create a custom app that essentially gives you nothing but a full screen web view.

This is exactly what Apple has done in their retail stores with their Smart Signs. They've disabled the home button and launch the iPad into what is essentially a full screen web view. All content you see on the Smart Signs is just HTML.

Thanks Liam. I left out a key part to my question. It has been decided already, by my bosses, that it will be a 32" touch display. – modernzombie Apr 16 '12 at 14:57
