KeyMenu: a keyboard based hierarchical menu
Kent Lyons, Nirmal Patel, Thad E. Starner · 2004
KeyMenu is a keyboard based hierarchical menu system originally designed for use on a wearable computer. The menu uses a one to one mapping between buttons on the keyboard and menu items. The KeyMenu leverages off of the advantages of other pointer based menus such as Marking Menus. It provides support for both novice and expert user interaction through the use of a delay in popping up the menu. Finally, by using a consistent physical action we support the transition from novice to expert.
