Navigation as Multiscale Pointing: Extending Fitts' Model to Very High Precision Tasks

Abstract

Fitts pointing model has proven extremely useful forunderstanding basic selection in WIMP user interfaces. Yet todaysinterfaces involve more complex navigation within electronicenvironments. As navigation amounts to a form of multi-scalepointing, Fitts model can be applied to these more complex tasks.We report the results of a preliminary pointing experiment thatshows that users can handle higher levels of task difficulty withtwo-scale rather than traditional one-scale pointing control. Also,in tasks with very high-precision hand movements, performance ishigher with a stylus than with a mouse.
