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.
