Segmentation of Endpoint Trajectories Does Not Imply Segmented Control (2009)
Exp Brain Res, Dagmar Sternad, Stefan Schaal
Abstract: While it is generally assumed that complex movements consist of a sequence of simpler units, the quest to define these units of action, or movement primitives, still remains an open...

Origins and violations of the 2/3 power law in rhythmic three-dimensional arm movements
Programmable pattern generators (2009)
Research on perceptuomotor coordination has traditionally been split into two distinct categories, rhythmic and discrete movement. While investigations of rhythmic movement have largely been...
Aaron Raftery, Joseph Cusumano, Dagmar Sternad
The question of how best to model rhythmic movements at self-selected amplitude-frequency combinations, and their variability, is a longstanding issue. This study presents a systematic analysis of a...

Abstract. This paper explores the idea to create complex human-like movements from movement primitives based on nonlinear attractor dynamics. Each degree-of-freedom of a limb is assumed to have two...
A Dynamical Approach to a Rhythmic Movement Task o (2007)
Stefan Schaal, Dagmar Sternad, Christopher G. Atkeson
The skill of rhythmic juggling a ball on a racket is investigated from the viewpoint of nonlinear dynamics. The difference equations that model the dynamical system are analyzed by means of local and...
Origins and violations of the 2/3 power law in rhythmic 3D movements (2001)
The 2/3 power law, the nonlinear relationship between tangential velocity and radius of curvature of the endeffector trajectory, has been suggested as a fundamental constraint of the central nervous...

Learning passive motor control strategies with genetic algorithms (1993)
Abstract: This study investigates learning passive motor control strategies. Passive control is understood as control without active error correction; the movement is stabilized by particular...
