One Fitts’ Law, Two Metrics [PDF]

, 2017
Movement time in Fitts’ law is usually considered through the ambiguous notion of the average of minimum movement times. In this paper, we argue that using two distinct metrics, one relating to minimum time and the other relating to average time can be advantageous. Both metrics have a lot of support from theoretical and empirical perspectives. We also

Augmented feedback influences upper limb reaching movement times but does not explain violations of Fitts' Law [PDF]

Frontiers in Psychology, 2015
Fitts’ (1954: J Exp Psychol) classic theorem asserts that the movement time (MT) of voluntary reaches is determined by amplitude and width requirements (i.e., index of difficulty: ID).

Assessment of Fitts’ Law for Quantifying Combined Rotational and Translational Movements [PDF]

, 2010
Objective: To develop a model for human performance in combined translational and rotational movements based on Fitts' law. Background: Fitts' law has been successfully applied to translational movements in the past, providing generalization beyond a ...

Insight into Goal-Directed Movements: Beyond Fitts’ Law [PDF]

, 2009
Various methods and measures have been developed to assess the quality of input devices and interaction techniques. One approach to investigating the performance of input devices and interaction techniques is to focus on the quality of the produced movements.

Fitts’ Law in Tongue Movements of Repetitive Speech [PDF]

Phonetica, 2019
AbstractFitts’ law, perhaps the most celebrated law of human motor control, expresses a relation between the kinematic property of speed and the non-kinematic, task-specific property of accuracy. We aimed to assess whether speech movements obey this law using a metronome-driven speech elicitation paradigm with a systematic speech rate control ...

Hemodynamic activity is not parsimoniously tuned to index-of-difficulty in movement with dual requirements on speed-accuracy [PDF]

Frontiers in Human Neuroscience
BackgroundReaching movements are crucial for daily living and rehabilitation, for which Fitts' Law describes a speed-accuracy trade-off that movement time increases with task difficulty. This study aims to investigate whether cortical activation in motor-

Beyond Fitts' law [PDF]

CHI '97 extended abstracts on Human factors in computing systems looking to the future - CHI '97, 1997
As a developing discipline, research results in the field of human computer interaction (HCI) tends to be "soft". Many workers in the field have argued that the advancement of HCI lies in "hardening" the field with quantitative and robust models. In reality, few theoretical, quantitative tools are available in user interface research and development. A

Fitts' law is not continuous in reciprocal aiming. [PDF]

Proc Biol Sci, 2010
It takes longer to accomplish difficult tasks than easy ones. In the context of motor behaviour, Fitts' famous law states that the time needed to successfully execute an aiming movement increases linearly with task difficulty. While Fitts' explicit formulation has met criticism, the relation between task difficulty and movement time is invariantly ...

A Study of Model Iterations of Fitts’ Law and Its Application to Human–Computer Interactions [PDF]

Applied Sciences
Fitts’ law, a predictive model for motor task completion time, is widely utilized in human–computer interaction (HCI) research. While its formulas in two dimensions have achieved consensus over the decades, research diverges on its application in three ...

Speed-accuracy trade-offs in action perception, motor imagery, and execution of hand movements in autistic and non-autistic adults [PDF]

Scientific Reports
Action perception, execution, and imagery share motor-cognitive processes. Given prevalent sensory and motor coordination difficulties in autism, the processes of action perception and imagery may also be altered. This study investigated whether autistic
