Usability Quote of the Day

And let it be noted that there is no more delicate matter to take in hand, nor more dangerous to conduct, nor more doubtful in its success, than to set up as the leader in the introduction of changes. For he who innovates will have for his enemies all those who are well off under the existing order of things, and only lukewarm supporters in those who might be better off under the new. -- Niccolò Machiavelli, The Prince (trans.

Circular Menus and Usability

Circular menus. Ever heard of them? I'm not sure if they have an "official" or "common" name, but this name is pretty descriptive.

Look at the iPod buttons, for example. Play/Pause, the most common function, is in the middle, and the other functions are equal distances from there.

Also check out the SecondLife context "spin menu". The pie pops up surrounding the cursor, and all the available options are an equal twitch away from the center.

Submenus? Just expand the circle. For example, here's a quick mockup I made converting much of my current FireFox context menu into a pie menu:"    (Continued via Tech Knack)    [Usability Resources]
