In fact, it takes a lot of skill to convert a desired motion on the screen to an appropriate nudge of the joystick. Thus, joysticks usually result in a lot of "hunting" as the cursor constantly overshoots the target and the user applies smaller and smaller corrections to get it to land on the desired point on the screen. See Stu Card's thesis; I know he presented the reasons at his oral (I was there) and assume they are also in his thesis. I have no experience with tracking balls, and am currently reluctant to offer opinions on them since I THINK I know a very, very cute way to implement one...and I won't say more until I've sold the idea. joe ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
