Fitts' Law

Thanks to Jared Spool‘s Usability Tools Podcast, I am no longer ignorant about Fitts’ Law.

Fitts’ Law, according to the Wiki, is

“a model of human movement which predicts the time required to rapidly move to a target area, as a function of the distance to the target and the size of the target.”

It’s a basic guide to the act of pointing; it helps you predict human motion based on rapid movement – which is great for interface design, especially on the Web.

I used to tune in a lot to Spool’s podcasts but I’ve been busy lately, so I haven’t really had time to sit back with a cup of coffee and chill.

But that must be the upside to being busy, I guess. You get to periodically rediscover shit you’re into.
