Identification of Users' Well-Being Related to External Stimuli: A Preliminary Investigation

摘要

In this paper, the authors have investigated the possibility of evaluating the well-being of the user, in relation to external stimuli, by means of continuous monitoring of physiological quantities. This preliminary analysis has interested the extraction of features from Electro-Dermal Activity (EDA) signal and their correlation with different emotional states (i.e., Arousal). A low-cost system for continuous monitoring of EDA has been described, together with the experimental setup and the processing techniques applied. A unique indicator, which combines the features extracted from the raw waveform, has been discussed in the paper and applied in postprocessing. The implementation of the processing algorithms and the computation of the novel indicator allow to discriminate, with a statistical significance, the user perception, in case of high emotion events (i.e., from low level Arousal< 3 to high level one, > 6). More investigation is needed to improve the processing technique and validate the preliminary results obtained.
