Speed and accuracy tradeoff in whole body movement during vertical jumps under varying landing constraints [PDF]
Scientific ReportsThe speed-accuracy trade-off, described by Fitts’ law, has been well studied in fine motor tasks but remains insufficiently explored in whole-body movements, such as jumping.

Fitts' Law in early postural adjustments. [PDF]
Neuroscience, 2013 We tested a hypothesis that the classical relation between movement time and index of difficulty (ID) in quick pointing action (Fitts' Law) reflects processes at the level of motor planning. Healthy subjects stood on a force platform and performed quick and accurate hand movements into targets of different size located at two distances.

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 ...

Investigation of the parameters affecting Fitts' law on reciprocal arm movements
Nihon Kikai Gakkai ronbunshu, 2021 The speed-accuracy trade-off in motor tasks is well-known. An error within a movement can increase with the speed of the movement. Fitts’ law formulizes the relationship between speed and accuracy.

Evaluation of Driving Performance of Wheel Loader in the Framework of Fitts’ Law [PDF]
한국정밀공학회지, 2018 This paper proposes a novel method for evaluating the performance of control modalities related to driving a wheel loader, according to the framework of Fitts’ law and the steering law.

Speed-accuracy tradeoffs in human speech production. [PDF]
PLoS ONE, 2018 Speech motor actions are performed quickly, while simultaneously maintaining a high degree of accuracy. Are speed and accuracy in conflict during speech production?

A New Approach to Modeling the Prediction of Movement Time
Mathematics, 2021 Fitts’ law predicts the human movement response time for a specific task through a simple linear formulation, in which the intercept and the slope are estimated from the task’s empirical data.

Acta Psychologica, 2021 There are circumstances in which humans are required to move in environments wherein accuracy should be maximized, such as golf putting or surgeons’ hand movements during surgical procedures.

Predictive feedback control and Fitts–law [PDF]
Biological Cybernetics, 2008 Fitts' law is a well established empirical formula, known for encapsulating the "speed-accuracy trade-off". For discrete, manual movements from a starting location to a target, Fitts' law relates movement duration to the distance moved and target size.
