No, this won't be used in the field.
Actually, it will be used for Manufacturing and Quality Assurance jobs ie Hardware inspection checklists, processing incoming units, etc...
I have done a little study and found that the touch screen technology is not in the Programming Language, rather, it is in the drivers related to the Touch Screen Peripheral itself. This means that the touches to the screen work much like a mouse click, except they are performed by fingers or stylus, instead of mouse clicks.
If this is indeed the case, then it seems that the only provision that needs to be made in the code is to be careful what Events are used. ie On Mouse Over probably would not be a good choice. On Mouse Click, however, would still be appropriate.
It seems to me that aesthetic form design will also have to be altered a bit from the traditional style forms. Perhaps bigger buttons and fewer drop down boxes. Perhaps even using only buttons as opposed to combo boxes.
Let me know about any more input.
