Abstract(in English) EEG was used to sense brain activity when viewing four types of presentation videos with different "topic difficulty" and "explanation skills", and after generating multiple patterns of feature values from the EEG data, the difference between the two types was evaluated. As a result of Wilcoxon test with six evaluation cases, it was confirmed that the feature value that makes it easy to distinguish between the two types differs for each evaluation case. In addition, in the evaluation of the correct answer rate using machine learning, when we generated classifiers for 16 experiment participants, we recorded a maximum correct answer rate of 71% (+21% from the chance level), and we also confirmed the superiority of using multiple feature values generated from theta, alpha, and beta waves at the same time.
