A Consideration of Production Methods of VR for Environmental Education [PDF]

, 2022
いまや映像は既存メディアの枠を超え、「体験する表現」へと進化している。本稿では、2020年10月に北海道と北海道大学CoSTEPで共同制作したヴァーチャル・リアリティ（VR）動画「バーチャル登山！アポイ岳」を事例に、体験型の環境教育用VRコンテンツの制作プロセスについて考察した。その結果、１）動線を作ることで時間、空間を追体験してもらい期待感や発見、到達の喜びをもたらすこと、２）２D（平面）動画を先に作ってからそれをベースにVRに変換することで、ストーリー性のあるVR動画を制作できること、３ ...
