Glossary » pie menu
a circular menu of options radiating out from where the user clicks. Each option occupies a pie slice. Because each option is equally distant, menu selection can be faster than with traditional pull-down menus. The geometry of the pie menu makes it work best for selecting icons rather than text. Also, when the number of options is kept reasonably small, a shortcut allows a user to swipe their pointer in a quick gesture to indicate their selection without waiting for the menu to appear.
