When you go into a library and they've got a big, unmovable book that sits on a pedastal, what kind of orientation is it in? When you lay out a cookbook in the kitchen, or you're transcribing papers onto your screen, what orientation are they in?
Basically the one I am describing. A little elevated at the top, with the end nearer to you and closer to the working surface, on some sort of stand designed just for this purpose. "Propped up". Most ATMs or other touch Kiosks, is the panel FLAT and facing you, or slightly inclined? When use the automated ticket kiosk at the movie theater?
The problem isn't that touch-screen is uncomfortable on a desktop - it is that a desktop is poorly oriented for a touch experience.
Huh? Did I just fix that problem? I think I did. I am so much wasted talent and potential. I should be designing things for Apple, not managing unruly IT workers and writing Tech Blogs.
