Do you want to work on a touch-screen mounted vertically? I find them comfortable when horizontal or slightly angled. Not at all ergonomic when mounted as a standard display.
Quite so. The effect is know as Gorilla Arm. From the Jargon File:-
Quote:
The side-effect that destroyed touch-screens as a mainstream input technology despite a promising start in the early 1980s. It seems the designers of all those spiffy touch-menu systems failed to notice that humans aren't designed to hold their arms in front of their faces making small motions. After more than a very few selections, the arm begins to feel sore, cramped, and oversized — the operator looks like a gorilla while using the touch screen and feels like one afterwards. This is now considered a classic cautionary tale to human-factors designers; “Remember the gorilla arm!” is shorthand for “How is this going to fly in real use?”.
Tablets and other touch screens work when you can get to them confortably. Shoving it up beside the screen is just repeating an old mistake. Reinventing the tarpit?
