Utils Email Jason Intro A Pie Menu is a circular menu that lets people choose items by dragging the pointing device in the direction of the menu item. Compare this with linear popup menus. The target area for selecting a menu option is larger than linear popup menus, since you can just extend each pie slice to the edges of the screen.
People tend to recall angles better then positions in linear lists.
There is also muscle-memory involved, where your muscles remember the actions to take for a command. PieMenu JavaDoc Documentation is available. Javadoc Documentation for all of the GUIR research group's software is also available. Some Pie Menu Images Two sample images of how the pie menu works.
