Fitts’ Law Misunderstood
2010-03-12 13 Comments
Fitts’ Law is being thrown around quite often. Some people seem to think that it is all about how the edges of the screen and especially the corners are easy/fast to hit with the pointer. We have to thank Tog for that 😉 This is at least not entirely wrong, but I also saw claims it would have to do with targets becoming harder to hit if you place other targets in close proximity.
It really only covers: The time to acquire a target is a function of the distance to and size of the target. It has to be noted that this does only refer to linear movement, so the size of the target has to be measured along the axis of movement.
