A new technique for the classification of pre-meditative and meditative states

The classification of HRV signal through the geometry of Poincaré´ plot and its quantification is one of the popular techniques in nonlinear analysis. The quantification is generally done by fitting an `ellipse´ on the constructed Poincaré plot of HRV signal. However, most of the meditative and pre-meditative states cannot be distinguished from Poincaré´ plot. In this paper we introduce a new notion called modified angle map by which it is possible to classify the meditative and pre-meditative states significantly.
