Why are those 3d/space balls always sitting way forward on someone's
desk? Why not beside the chair, or held in the lap like a game
controller? In the dark ages I tried making a strap for a spaceball so
I could hold it on my thigh, but it was just too damned heavy.
Also, see "Gorilla Arm" in the Hacker's Dictionary:

gorilla arm /n./
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?".
