Fitts's Law Holds for Action Perception
Psychological Science, 2007Fitts's law is one of the most well-established principles in psychology. It captures the relation between speed and accuracy in performed and imagined movements. The aim of this study was to determine whether this law also holds during the perception of other people's actions.

Reporting and Visualizing Fitts's Law
Proceedings of the 2016 CHI Conference Extended Abstracts on Human Factors in Computing Systems, 2016In this paper we compare methods of reporting and visualizing Fitts regressions. We show that reporting this metric using mean movement time per user over accuracy-adjusted Index of Difficulty (IDe) produces more descriptive visualization. This method displays variance, which is more useful in understanding the interfaces, than an aggregated means-of ...

Journal of Motor Behavior, 1979
This paper presents a reappraisal of Fitts' (1954) law and outlines reasoning which predicts that, for tasks of equivalent difficulty as calculated by Fitts' Index of Difficulty, smaller-tolerance tasks will, within limits, take longer to perform. Reanalysis of Fitts' data appears to confirm this view.

Generalized Fitts' law model builder
Conference companion on Human factors in computing systems - CHI '95, 1995A tool for designing experiments, capturing data, and building Fitts’ law models is described. The software runs on an IBM or compatible computer equipped with an appropriate graphical display and selection device (e.g., mouse, joystick). Features intended for HCI educational purposes or experimental research are included, making this a very powerful ...

Diving, Adaptation, and Fitts Law
Journal of Motor Behavior, 1978To assess Welford's dual controlling factor interpretation of Fitts' law, 20 scuba divers performed a reciprocal tapping task. In an attempt to separate the two factors, the subjects were tested on land and underwater. This does not change the basic parameters of the task but does put the subjects under informational stress, in that underwater the ...

Fitts' law in two-dimensional task space
Experimental Brain Research, 1994A traditional continuous Fitts' task may be described as a one-dimensional oscillation between two targets. The combination of two such oscillations along intersecting axes gives rise to a two-dimensional aiming task, allowing the study of the speed-accuracy trade-off in two-dimensional task space. In two experiments subjects were asked to draw as many

Fitts' law and expanding targets
ACM Transactions on Computer-Human Interaction, 2005Recently, there has been renewed interest in techniques for facilitating the selection of user interface widgets or other on-screen targets with a pointing device. We report research into using target expansion for facilitating selection. Widgets that expand or grow in response to the user's focus of attention allow

Extending Fitts’ Law to manual obstacle avoidance
Experimental Brain Research, 2007In this study we asked whether Fitts' Law, a well-established relationship that predicts movement times (MTs) for direct movements between two positions, could be extended to predict MTs for curved, obstacle avoiding, movements. We had participants make movements in the presence of an obstacle.

Fitts' Law with transmission delay
Ergonomics, 1992It is shown that a modified form of Fitts’ Law applies when there is a transmission delay between control movements and feedback of system response to the operator. The model predicts, and experiments verify, that a multiplicative relationship holds between movement time, Index of Difficulty (ID), and transmission delay. Movement time at constant ID is

Fitts’ law in the presence of interface inertia
2020 42nd Annual International Conference of the IEEE Engineering in Medicine & Biology Society (EMBC), 2020Collaborative robots are advancing the healthcare frontier, in applications such as rehabilitation and physical therapy. Effective physical collaboration in human-robot systems require an understanding of partner intent and capability. Various modalities exist to convey such information between human agents, however, natural interactions between humans
