Fitts' Corners
A good discussion about HCI based on an article shown below ...
"Procrastination led me to this article: Top 8 Reasons HCI is in its Stone-age. Among other things he asks: Why do modern Desktop Environments not exploit Fitts' Law?
One of the implications of Fitts' law is that there are five spots on a mouse-operated display that are easiest to target, the four screen-corners and the spot directly under the cursor. This is a fairly sensible conclusion, so why don't any major Desktop Environments exploit the screen corners?
I have a good reason: it's because they are the easiest spots to hit with the mouse.
Setup your OSX box to trigger Expose when you move the mouse to a corner. Now count how many times during the day you nudge the mouse into the corner and trigger Expose by accident. It's very useful to be able to easily trigger Expose, but it's very annoying to be able to easily trigger Expose. The annoyance is such that I would definitely argue against inflicting such behavior on people by default. Apple apparently agree with me, by default you can only activate Expose with the F12 key." continued ... (Via amaroK)
