A menu system often serves as the core interaction workhorse of an application. We have researched and productized a few solutions that enhance the user’s experience. Most notably is the marking-menu which allows a user to perform a menu selection by either popping-up a radial menu or by quickly making a straight mark in the direction of the desired menu without popping-up the menu. Other investigations have focused on providing efficient access to a large number of menu-items (the HotBox), menus for pen computers (tracking menus), for rapid tool switching (pieCursor) and multitouch environments (multitouch marking menus).
