Evaluation of Distance Learning Effects on Concentration and Relaxed States by EEG and HRV

The demand for distance learning is increasing due to the recent expansion of the COVID-19 pandemic. In distance learning, less communication level has been pointed out that it would reduce student’s concentration level in the study. However, these were subjective evaluations based on questionnaires, therefore, there was a lack of criteria to evaluate this problem. In this work, we propose a method to objectively evaluate distance learning using the biometric information to understand the difference of the student’s concentration level during the study. We measure the student’s electroencephalography (EEG) and heart rate variability (HRV) to evaluate the change of student’s emotion based on different communication condition during distance learning. In the experiment, we measured EEG and HRV of the students, while turning on and off face-to-face video camera. The analysis of results show that different communication condition effect student’s concentration level. We found that it could be due to their preferences of the subject.
