Pie-Menus in Mozilla

pronik writes "The Optimoz project on MozDev had two main development branches. While the first one, Mouse Gestures have been a success, we had to wait for the second, also very promising one: PieMenus. Now the wait is over! First implementation of PieMenus for Mozilla - RadialContext - is available for installation and testing!!!"

Pie menu advantages

[uhlume]

As I understand it, the primary advantage of pie menus over standard linear/cascading menus is that they leverage muscle memory for enhanced speed and accuracy in menu selections. In essence, pie menus are not unlike a gestural control scheme with training wheels -- a series of selections from a cascading pie menu effectively forms a complete mouse-gesture, which can later be replicated without conscious reference to menu labels. This allows novice users to make selections cognitively by following menu selections, while more advanced users can simply remember the series of mouse movements required to reach a given selection.

That site fails to list what is probably the second most well known use of 'pie' menus, after the Sims. Neverwinter Nights! The context menus you use to do basically everything are radial.

That brings up another good point, which is that from what I've seen none of the radial menu implementations (Moz's or his javascript ones) implement hotkeys, which for a lot of users (read: me) immensely improves speed. I didn't like NWN's radial menus at all, especially since they have a 9th zone in the middle, which is the 'close menu' or 'go back' function. That meant that you had to move the mouse a significant ways towards each icon, eliminating a lot of the speed gain. Then I found out that the keys on the Number Pad were hotkeys for each of the 8 directions (with 5 being a hotkey for the center zone, and 0 being a hotkey to popup the radial for your character.) After that I loved them. Need your familiar? 0-4-1. Need rapid shot mode? 0-3-7-3. That saved all my quickslots for spells, potions, and other life-saving bits. I played most of that game with my right hand on the mouse and my left moving between asdf and the number pad.

Of course, I have no idea whether I'll ever find a 'real' use for being able to 10-key with the wrong hand, but you never know. :)
