Representation of a Physio-psychological Index Through Constellation Graphs
Fingertip pulsations (plethysmograms) were found to obey chaotic dynamics [1]. We applied chaos theory to analysis of the time series of plethysmograms under various human physio-psychological conditions. It found out that the largest Lyapunov exponent of the time series could be used to characterize physio-psychological status. A visual representation method based on constellation graphs was developed to indexing the changes in the largest Lyapunov exponent.
