Diana(Dialog Analysis) is the research on an information system that supports the analysis of dialogue in group learning and uses wearable devices for intervention. We analyze occupancy and alternation from speech features of face-to-face and online discussions, and perform speech recognition of the content. These results are used to support participation through agent facilitation and to provide unexpected perspectives for group learning.

TASS(Teaching Assistant Supporting System) is the research on an information system to support the guidance of teaching assistants in programming learning. The system uses sensors to measure the position and posture of students while engaging in learning support activities in the classroom, and detects learners who need support and provides optimal support for each individual student. The system aims to change the behavior of teaching assistants through visualization and presentation of their characteristics.

学習者が着席する机にセンサを設置して，脚部動作の計測により状況を推定する手法の研究です．オンライン学習や自習に取り組む学習者が，関心があるか，難しいと感じているか，精神的に疲労しているかなどを機械学習により推定します．結果はリアルタイムに可視化したり，効果的な休憩タイミングを提案するなどの方法で学習者にフィードバックします．
ThinkLeg is the research of a method for estimating the situation of a learner by installing sensors on the desk where the learner is seated and measuring leg movements. Machine learning can estimate whether a learner is interested in online learning or self-study, whether the learner is finding it difficult, and whether the learner is mentally fatigued. The results are visualized in real time, and feedback is provided to the learner in the form of suggestions for effective break times. (Both leg and reed are pronounced the same in Japanese "ashi"; a pun of "man is a thinking reed")

協調学習における発話や身体動作を計測して可視化する，マルチモーダル分析の研究です．グループやペアでの学習活動における推移から，内面的状態を推定します．特に活動や理解の構造や転換点を情報システムで検出し，個別介入の必要がある状況を通知することによって学習支援に役立てます．
CSCL(Computer Supported Collaborative Learning) is the research of multimodal analysis that measures and visualizes speech and body movements in cooperative learning. We estimate the internal state from the transition in learning activities in groups or pairs. In particular, the structure and turning points of activities and understanding are detected by the information system and used to support learning by notifying situations that require individual intervention.
