KeyMenu: A Keyboard Based Hierarchical Menu

KeyMenu is a keyboard based hierarchical menu system intended for use on a wearable computer. It is designed for use in conjunction with the Twiddler one-handed wearable keyboard. Unlike traditional menus and shortcut keys, our system employs a one-to-one mapping between buttons on the keyboard and menu items. With the addition of a pop- up menu interaction technique, the KeyMenu design consis- tently supports both novice and expert users.
