category interface design

fitts’ law

The time to acquire a target is a function of the distance to and size of the target. (or, mathmatically, MT = a + b log2(2A/W + c))

I’ve been reading up on user interface design, and this stuff is fascinating. I’m finding it all through the humanized blog. i had been thinking that google calendars’ quick event entry system was brilliant and now i can explain it. it’s accessed by the fastest/largest target possible (wherever your mouse happens to be) and the options are severly limited for input. works great.

now do that for a wysiwig editor. (and what about that pie-chart menu idea? i think that’s swell and we should give it a try)
