Abstract
We proposed the design of a 4D digital viewing system for archiving the embodied creation process of Ikebana. Using twenty-two synchronized fixed cameras and a grasses type eye tracker, our system captures full-body motion, the evolving flower arrangements, and gaze behavior. Camera poses are estimated with COLMAP, and each video frame is independently reconstructed using 3D Gaussian Splatting, resulting in a space-time sequence that can be interactively viewed from arbitrary angles. This frame-wise reconstruction strategy lowers computational load and avoids temporal drift, enabling long-duration recordings on moderate hardware while maintaining spatial coherence. The resulting archive integrates body kinematics, spatial composition, frontal aesthetics, and visual attention, creating a rich, interpret able resource for researchers, educators, and practitioners. By making previously tacit techniques to systematic observation, the method supports both the cultural preservation of Ikebana and the development of new forms of skill transmission.

Designing a 4D Digital Archive for Ikebana: Toward Scalable and Interpretable Interactive Archiving of Cultural Performance
