Abstract

The algorithm of geometrical synchronization based on the optimal reconstruction of embedded attractors from heart rate variability (HRV) data is employed to detect temporary coherence between participants before, during, and after the Heart Lock-In experiment. The pairwise geometrical synchronization between individual participants help to detect the average coherence of the group. Geometrical shapes of the embedded attractors do provide an insight into the complexity of HRV data.
