Haken-Kelso-Bunz (HKB) Model

Abstract

First published in 1985, the HKB model [11] is probably the best known and most extensively tested quantitative model in human movement behavior. In its original form it describes the dynamics of the relative phase between two oscillating fingers or limbs under frequency scaling. The HKB model can be derived from coupled nonlinear oscillators and has been successfully extended in various ways, for instance, to situations where different limbs like an arm and a leg, a single limb and a metronome, or even two different people are involved. We shall use this model to show how dynamical systems theory can be used not only to describe and model experimental finding quantitatively but also to predict new phenomena.
