Modeling the Effect of Target Shape on Movement Performance in a 1D2D Fitts Task
Mathematics, 2022 Fitts’ law is used as a performance measurement metric in human–computer interactions. The original formulation implied that movement time was identical for movements with the same value of the index of difficulty under varied movement amplitude and ...

Perceived Cost and Intrinsic Motor Variability Modulate the Speed-Accuracy Trade-Off.
PLoS ONE, 2015 Fitts' Law describes the speed-accuracy trade-off of human movements, and it is an elegant strategy that compensates for random and uncontrollable noise in the motor system.

The Study of Model for Two-Handed Pointing Tasks in Pen + Touch Interfaces
IEEE Access, 2021 In pen + touch interfaces, two-handed pointing tasks are quite basic. We focus on two-handed pointing tasks on a stationary touchable tablet under asynchronous conditions, in which another target will not appear until one target is touched and dwelled ...

Fitts’ Law is modulated by movement history [PDF]
Psychonomic Bulletin & Review, 2017 Fitts' Law is one of the most robust and well-studied principles in psychology. It holds that movement time (MT) for target-directed aiming movements increases as a function of target distance and decreases as a function of target width. The purpose of this study was to determine whether Fitts' Law is affected not only by the demands of the target on ...

An alternative to Fitts’ law [PDF]
Bulletin of the Psychonomic Society, 1980 A new power law of movement time for motor control tasks is proposed as an alternative to the classical Fitts’ law. A reanalysis of Fitts’ original data indicates that this power law may provide superior fits to those of Fitts’ law, which may be interpreted as a special case of the power law.

Using Fitts' Law to Detect Intentional Misrepresentation [PDF]
Journal of Motor Behavior, 2015 In paralympic classification, tests of impaired coordination (e.g., reciprocal tapping tasks) are effort dependent and therefore susceptible to intentional misrepresentation of abilities (IM)-deliberate exaggeration of impairment severity. The authors investigated whether reciprocal tapping tasks performed submaximally could be differentiated from ...

Evaluation of Hands-Free VR Interaction Methods During a Fitts’ Task: Efficiency and Effectiveness
IEEE Access, 2023 Currently, it is standard to use tracked handheld controllers for interaction in immersive virtual reality (VR). However, since VR interactions are becoming more natural with hand tracking, it is important to provide hands-free alternatives for selection
