A Survey on Human Stress Detection Using Physiological Signal

Abstract

This article presented various research studies on the analysis of bio-signal and investigates how the human stress is manifested with the bio-signal. The bio-signal such as EEG, ECG, Heart rate, speech signal are investigated for different stressors. The prime aim of such an investigation is to share the technical overview of human stress and it's mechanism for understanding human stress and it is associated with bio-signal. In this article the direction on the feature set used for stress detection are given, also the information on the fusion of feature set is presented for better recognition. In spite of that the effect of human stress and signal anatomy is surveyed. This investigation throw more light on the study of stress mechanism, stressors, bio-signals and it's feature set
