Bootsma, R. J., Fernandez, L. and Mottet, Deni (2004): Behind Fitts' law: kinematic patterns in goal-directed movements. In International Journal of Human-Computer Studies, 61 (6) pp. 811-821.

Half a century ago, Paul Fitts first discovered that the time necessary to complete a pointing movement (MT) linearly increases with the amount of information (ID) necessary to specify the target width (W) relative to the distance (D). The so-called Fitts' law states that, with ID being a logarithmic function of the D/W ratio. With the rising importance of pointing in human-computer interaction, Fitts' law is nowadays an important tool for the quantitative evaluation of user interface design. We show that changes in ID give rise to systematic changes in the kinematics patterns that determine MT, and provide evidence that the observed patterns result from the interplay between basic oscillatory motion and visual control processes. We also emphasize the generality and abstract nature of Fitts' robust model of human psychomotor behavior, and suggest that some adaptations in the design of the (computer-mediated) coupling of perception and production of movement might improve the efficiency of the interaction.

(eds.) Proceedings of the ACM CHI 99 Human Factors in Computing Systems Conference May 15-20, 1999, Pittsburgh, Pennsylvania. pp. 450-457.

Fitts' pointing model has proven extremely useful for understanding basic selection in WIMP user interfaces. Yet today's interfaces involve more complex navigation within electronic environments. As navigation amounts to a form of multi-scale pointing, Fitts' model can be applied to these more complex tasks. We report the results of a preliminary pointing experiment that shows that users can handle higher levels of task difficulty with two-scale rather than traditional one-scale pointing control. Also, in tasks with very high-precision hand movements, performance is higher with a stylus than with a mouse.
