Abstract (in Japanese) (See Japanese page) 
(in English) In groupwork studies, not only final work products, also how proactively group members contribute to the work and how collaborate each other have significance.
The way of analyzing those aspects objectively and quantitatively will be a good tool for learning analytics and student support based on that.
With this motivation, the present study proposes groupwork features using hand emergence in ego-centric views of group members, and an automatic method to extract them.
Arm information including direction and location is used to recognize owners of hands detected by a deep learning-based detector.
We confirmed that even the simple groupwork features using hand region area can give us meaningful indications about groupwork situation, collaboration patterns, role allotment, and individual contribution.
