Dimensionality Reduction in Control and Coordination of the Human Hand

Abstract: The concept of kinematic synergies is proposed to address the dimensionality reduction problem in control and coordination of the human hand. This paper develops a method for extracting kinematic synergies from joint-angular-velocity profiles of hand movements. Decomposition of a limited set of synergies from numerous movements is a complex optimization problem. This paper splits the decomposition process into two stages. The first stage is to extract synergies from rapid movement tasks using singular value de… Show more

“…Also shown in the figure are the hand postures of the reconstructed movement across time. As these synergies preserve both the temporal structure and the postural information these are termed as temporalposturalsynergies ( Vinjamuri et al (2010a;). …”

“…Explicit representations for dynamic shape manifold were studied on moving humans to recognize actions using low-dimensional embedding by locality preserving projections (LPP) [5]. Mao proposed the concept of kinematic synergies to address the dimensionality reduction problem for hand movement control and coordination [6]. Optimization technique was applied to find the weights and firing timings of extracted synergies, decomposing basic motions.…”
