Abstract:

The strong relationship between physical health and emotional status of an individual is well-known since many decades. Today, the availability of wearable sensors to easily and accurately measure Electrodermal Activity on a long-term paves the way to many potential applications in different fields, where the quantification of emotions is important to classify the subject's reactions to different types of stimuli. Based on the use of the Empatica E4 wrist-worn device, this work investigates which features, in Electrodermal Activity signals, are more significant for the tonic or phasic component, which are more informative and meaningful for a certain subject, and which are not very informative, focusing on the responses elicited by physical stimuli of different intensities. The results show that time-domain features support subject-dependent physiological information, whereas frequency-domain features are effective in discriminating different levels of physical efforts, and associating them to the tonic or phasic component.
