The paper concerns technology of automatic emotion recognition applied in e-learning environment. During a study of e-learning process the authors applied facial expressions observation via multiple video cameras. Preliminary analysis of the facial expressions using automatic emotion recognition tools revealed several unexpected results, including unavailability of recognition due to face coverage and significant inconsistency between the results obtained from two cameras. The paper presents the experiment on e-learning process and summarizes the observations that constitute limitations of emotion recognition from facial expressions applied in e-learning context. The paper might be of interest to researchers and practitioners who consider automatic emotion recognition as an option in monitoring e-learning processes.
