We build on the variability of human movements by focusing on how the stochastic variance of the limb position varies over time. This implies analyzing a whole set of trajectories at once rather than a single trajectory. We show, using real data previously acquired by two independent studies, that in a tapping task, the positional variance profiles are unimodal. The first phase, where positional variance increases steadily, is followed by a second phase where positional variance decreases until… Expand

TLDR
The proposed information-theoretic model has promise to improve the understanding of human aimed movements and shows that the variance decreases exponentially at a rate given by the channel capacity. Expand
Modeling the speed-accuracy tradeoff using the tools of information theory. (Modélisation du compromis vitesse précision d'une tâche de pointage humain à l'aide des outils de la théorie de l'information)
TLDR
Le mouvement peut-etre decoupe en deux phases: une premiere ou the variance augmente et une grande partie de the distance a couvrir est parcourue, est suivie d’une deuxieme au cours de thequelle the variance diminue pour satisfaire les contraintes de precision requises par the tache. Expand

Fitts' law as the outcome of a dynamic noise filtering model of motor control
TLDR
An alternative, noise filtering model of motor control is presented proposing that the psychomotor system is an inherently noisy mechanical system for which spatial demands should be formulated in terms of a desired signal-to-noise ratio between goal-related propulsion of the limb (signal) and stochastic error (noise).

TLDR
An alternate derivation from a model assuming continuous velocity control of hand position is shown to fit the motion time data equally well, and an internal “secondary positional reference” must be postulated to explain results obtained when S is deprived of visual feedback. Expand
Optimality in human motor performance: ideal control of rapid aimed movements.
TLDR
The present conceptual framework provides insights into principles of motor performance, and it links the study of physical action to research on sensation, perception, and cognition, where psychologists have been concerned for some time about the degree to which mental processes incorporate rational and normative rules. Expand
Basic functions of variability of simple pre-planned movements
TLDR
The variability time profiles can be expanded on a special system of basic functions corresponding to established movement parameters, and a conclusion can be made, that reaching movement belongs to the type of simple preplanned movements. Expand
Control Theoretic Models of Pointing
TLDR
It is concluded that control theory offers a promising complement to Fitts’ law based approaches in HCI, with models providing representations and predictions of human pointing dynamics, which can improve the understanding of pointing and inform design. Expand
Information entropy analysis of discrete aiming movements.
TLDR
The entropy analysis revealed structure to the variability of the movement trajectory and outcome that has been masked by the traditional distributional analyses of discrete aiming movements. Expand

TLDR
The motor system in the present case is defined as including the visual and proprioceptive feedback loops that permit S to monitor his own activity, and the information capacity of the motor system is specified by its ability to produce consistently one class of movement from among several alternative movement classes.

Humans use continuous visual feedback from the hand to control fast reaching movements
TLDR
P perturbation technique provides direct evidence that the human brain uses visual feedback from the hand in a continuous fashion to guide fast reaching movements throughout their extent. Expand
Speed-accuracy tradeoffs in aimed movements: Toward a theory of rapid voluntary action.
TLDR
The present chapter reviews the evolution of speed-accuracy tradeoff research and shows how a fresh perspective regarding the properties of elementary movement mechanisms may be obtained. Expand
