Extending Fitts' law in three-dimensional virtual environments with current low-cost virtual reality technology

Int. J. Hum. Comput. Stud., 2020
Virtual reality (VR) interfaces require users to perform three-dimensional reaching and pointing movements to interact with objects positioned within the user's arm's reach.

The Reciprocal Nature of Fitts’ Law in Space and Time

Journal of Motor Behavior, 2022
Human movement takes place in both space and time so that measures of movement accuracy in space are made with respect to time, and vice-versa providing a foundation to the proposal of the complementarity of spatial and temporal error in aiming movements.

Adapting Fitts’ Law and N-Back to Assess Hand Proprioception

CHI Extended Abstracts, 2021
Proprioception is the body’s ability to sense the position and movement of each limb, as well as the amount of effort exerted onto or by them. Methods to assess proprioception have been introduced before, yet there is little to no study on assessing the ...

A Systematic Review of Fitts' Law in 3D Extended Reality

International Conference on Human Factors in Computing Systems
Fitts’ law is widely used as an evaluation tool for pointing or selection tasks, evolving into diverse applications, including 3D extended reality (XR) environments like virtual, augmented, and mixed reality.

An Extended Fitts’ Law Model for Hand Interaction Evaluation in Virtual Reality: Accounting for Spatial Variables in 3D Space and the Arm Fatigue Influence

International journal of human computer interactions
Fitts’ law is a standard tool for assessing user performance and interaction device effectiveness in human-computer interaction (HCI). However, it disregards spatial variables in 3D space and arm fatigue impacts.

Relative Merits of Nominal and Effective Indexes of Difficulty of Fitts’ Law: Effects of Sample Size and the Number of Repetitions on Model Fit

International journal of human computer interactions
Two formulations of Fitts’ index of difficulty ID are empirically compared under different subjective speed-accuracy biases: the nominal form IDn and the effective form IDe using endpoint variability.

Understanding Visual-Haptic Integration of Avatar Hands Using a Fitts' Law Task in Virtual Reality

Message Understanding Conference, 2019
Virtual reality (VR) is becoming more and more ubiquitous to interact with digital content and often requires renderings of avatars as they enable improved spatial localization and high levels of presence.

Effects of Gain and Index of Difficulty on Mouse Movement Time and Fitts’ Law

IEEE Transactions on Human-Machine Systems, 2019
The mouse, being the major means of inputting and controlling data on a computer, should be set right for best performance. Mouse gain, defined as the ratio of the movement distance on the computer screen to the movement distance of the mouse, controls ...

Dwell time reduction technique using Fitts' law for gaze-based target acquisition

Eye Tracking Research & Application, 2018
We present a dwell time reduction technique for gaze-based target acquisition. We adopt Fitts' Law to achieve the dwell time reduction. Our technique uses both the eye movement time for target acquisition estimated using Fitts' Law (Te) and the actual ...
