Fitts and VR: Evaluating Display and Input Devices with Fitts' Law
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 1997This paper describes an experiment using Fitts' Law to evaluate performance in target acquisition tasks comparing a typical virtual reality (VR) display and input device with a typical computer workstation display and input device. The objective was to determine the effects of using VR hardware on target acquisition performance and validate Fitts' Law

Violations of Fitts’ Law in a Ballistic Task
Journal of Motor Behavior, 2009The authors explored changes in the postural preparation and movement times during jumps into targets of different sizes placed at different distances from the participant. Both movement and preparation times scaled with movement distance. Neither movement nor preparation time showed an effect of target size, although preparation time showed a tendency

Feedback Control of Hand-Movement and Fitts' Law
The Quarterly Journal of Experimental Psychology Section A, 1983Fitt's empirical result is stated and its information theoretic interpretation briefly discussed. An alternate derivation from a model assuming continuous velocity control of hand position is shown to fit the motion time data equally well. Detailed studies of hand motion trajectories in Fitts' reciprocal tapping task have confirmed the exponential ...

Movement time and accuracy, as defined by Plamondon & Alimi, do not conform to empirical definitions. When definitions are used that conform better to empirical ones, the original predictions of the kinematic theory are no longer valid – as is demonstrated by simulations.

Biasing response in Fitts' Law tasks
CHI '06 Extended Abstracts on Human Factors in Computing Systems, 2006Fitts' law, relating the time to acquire a target to the target size and the distance from the target, is an effective and widely used predictor of performance in feedback controlled human motor targeting tasks. Beyond target size, however, movement time also varies according to a subject controlled mental trade-off between speed and accuracy for a ...

The effects of probe length on Fitts’ law
Applied Ergonomics, 2002Experiments were aimed at determining the effect of a human using an extended probe when making movements that required accuracy at the completion of the movement. Ten subjects performed 64 conditions of varying amplitude of movement, final accuracy and probe length.

Fitts' law, movement time and intelligence
Personality and Individual Differences, 1997Abstract Recently, several published studies have reported an empirical relationship between Movement Time (MT, i.e. the speed associated with sensori-motor control of movement) and intelligence. However, this finding is very much at odds with early research that suggested that there was no relationship between measures of these two constructs.

Only one Fitts' law formula please!
CHI '10 Extended Abstracts on Human Factors in Computing Systems, 2010The HCI community uses at least four different formulas for Fitts' law. Each of them is derived from Shannon's information theory. This raises the question which formula is wrong and which is right. While the HCI community on the one hand gives free choice for the formula, it demands good statistical values for the evaluation on the other hand.

Application of Fitts' Law to Foot-Pedal Design
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1975Two experiments on reciprocal foot tapping between pedals showed that a modified version of Fitts' Law can predict movement time for a variety of pedal sizes and separations. Using a relationship between times for reciprocal tapping and single movements found for hand movements, the present results predict closely the movement times obtained under ...
