The Limits of Expert Performance Using Hierarchic Marking Menus
Gord Kurtenbach, Bill Buxton
ACM SIGCHI Conference on Human Factors in Computing Systems
1993
Abstract
A marking menu allows a user to perform a menu selection by either popping-up a radial (or pie) menu, or by making a straight mark in the direction of the desired menu item without popping-up the menu. A hierarchic marking menu uses hierarchic radial menus and “zig-zag” marks to select from the hierarchy. This paper experimentally investigates the bounds on how many items can be in each level, and how deep the hierarchy can be, before using a marking to select an item becomes too slow or prone to errors.
