Outline of Final Research Achievements

We proposed a method to create an educational material video for Kiken Yochi (hazard prediction) training, so that people can learn practical knowledge in mountaineering proactively. The proposed method is to process images to change the situation to that of a near-miss to the material video of mountain climbing to visualize near-miss experiences. For global image processing that changes the entire scene, a moving image representing changes in conditions, such as fog, is artificially generated and combined with the source moving image. On the other hand, in local image processing that changes a part of a scene, the image that represents the scene to be changed is appropriately pasted onto each frame image of the material video.
We verified that the teaching material videos generated by the proposed method are effective as teaching materials that evoke scenes from mountain climbing sites and lead to the learning of practical knowledge.

Academic Significance and Societal Importance of the Research Achievements

危険予知トレーニングを持続的に行うには適切な教材の確保が大きな課題であり、実践知の発見と共有につながる教材作成方法は未解決である。本研究では、他者のヒヤリハット体験の閲覧時に現場の状況や事故発生の要因が想起されるようなヒヤリハットを可視化した動画の生成方法を提案し、その有効性を検証した。
教材動画の生成技術を適用することで、登山のリスクマネジメントについて学びあう実践知の伝承コミュニティを創出することが期待できる。登山分野だけでなく、防災教育、レスキュー技術などの分野にも展開すれば、多くの分野において、個人の主体的な学びとコミュニティの協調行動による新しい技能伝承の基盤が実現できる。
