The psychophysiological method uses physiological signals, such as facial electromyography (EMG), electrodermal activity (EDA), and electrocardiography (ECG) for investigating different psychological processes

However, there is still a gap in research efforts moving from laboratory studies to real-world settings. A small number of research has verified when a physiological response is a reaction to an extrinsic stimulus of the participant’s environment in real-world settings.

We developed an automatic stress detection system using physiological signals obtained from unobtrusive smart wearable devices which can be carried during the daily life routines of individuals.

reporter response is highly dependent on culture age and cell population density
