Research Abstract

It was found that there was a statistically significant relation between sleepparameters which were obtained from hypnogram (created from biological signals measuredby polysomnography) and the subjective evaluation of sleep. Further, a method which couldestimate the subjective evaluation of sleep indirectly through estimating sleep stages(obtained from quantitative values by analyzing biological signals) was also proposed.As stated above, it was suggested that there was a possibility to associate sensibilitywords representing "quality of sleep" due to psychological assessment, and physiologicalevaluation by quantitative analysis of biological signals
