- Abstract
- Describes an experiment exploring both articulatory and cognitive aspects of marking menus for different numbers of items per menu and using different input devices (mouse; trackball and stylus). The articulatory aspects are how well subjects could execute the physical actions necessary to select from pie marking menus. Subjects were given the task of either mentally representing the menu or associating marks with the commands they invoked trough practice. Subjects' performance degraded as the number of items increased. When menus were hidden, however, subjects performance did not degrade as rapidly when menus contained even numbers of items. Subjects performed better with the mouse and stylus than with the trackball
