Leap Motion を用いたアート制作 ― 仮想空間における物体の把持と解放を中心に ― Art Production by Use of Leap Motion ― Focused on Grabbing and Releasing Objects by Hands in the Virtual Space ― 永江, 孝規 3407 ナガエ, タカノリ Nagae, Takanori 3408 A hand gesture input device, called Leap Motion, has been utilized in virtual reality artworks since 2012 to capture hand and finger motions, with comparatively reliable precision. The device detects all the coordinates of the finger joints, as well as the positions of both palms and wrists in real time. Although many implementations have been proposed, some difficulties remain for grabbing or releasing 3D objects with the virtual fingers. Each of the fingers as well as the palms has its own collider, to detect collisions with objects, but sometimes it simply bumps against objects, pushing away them, unable to hold objects stably in the palms. I attach an inner collider and an outer trigger to an object to interact with finger-tip triggers for smoothly grabbing and releasing the object. departmental bulletin paper 東京工芸大学芸術学部 2019-03-31 application/pdf 東京工芸大学芸術学部紀要 25 31 38 Bulletin of Faculty of Arts, Tokyo Polytechnic University AN10507753 13493450 https://kougei.repo.nii.ac.jp/record/2022/files/25-4.pdf https://kougei.repo.nii.ac.jp/records/2022 jpn
