| Outline of Final Research Achievements |
This study investigated the features that can be used to estimate the concentration of users while working with a PC. The keyboard operation logs, body movement, heartbeat, pulse, and gaze were measured during the work of creating the text. As a result, it became clear that the following characteristics appear when concentrating; the number of times the keys on the keyboard are pressed varies; the frequency of body movements and the amount of movement decrease; the sympathetic nerves increase and the parasympathetic nerves are suppressed, resulting in a stressed state. In addition, it was clarified that when reading a sentence containing esoteric characters that hinder concentration, the gaze stays on the esoteric characters for a long time.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で明らかにした集中度推定に使用可能な特徴を用いることにより，今後，集中度を推定するための手法の開発が可能になる。PC作業中の集中度推定が可能になると，講義受講者が作業に集中できないタイミングを発見して助言等を行えるようになるため，教育効果の向上が期待できる。本研究で得られた成果は，遠隔授業中の受講者の心理状態を把握するための要素技術になり得る。
