- Proposed a 4D digital viewing system to archive the embodied creation process of Ikebana.
- System uses 22 synchronized fixed cameras and an eye tracker to capture full-body motion, flower arrangements, and gaze.
- Camera poses estimated with COLMAP; each video frame independently reconstructed using 3D Gaussian Splatting for interactive viewing.
- Frame-wise reconstruction reduces computational load, avoids temporal drift, and supports long recordings on moderate hardware.
- Archive integrates body kinematics, spatial composition, aesthetics, and visual attention for researchers, educators, and practitioners.
- Method supports cultural preservation of Ikebana and new skill transmission through systematic observation of tacit techniques.
- Collaboration with Assoc. Prof. Yokokubo at the University of Tokyo.
