TracKenzan: Digital Flower Arrangement Using Trackpad and Stylus Pen

摘要

We propose "TracKenzan," a training system for Ikebana (Japanese flower arrangement) in a 3D computer graphics space using a trackpad and a stylus pen. Ikebana includes a Kenzan, a flat metal base with hundreds of upward-pointing pins to hold flowers and branches in place. In the proposed system, a trackpad represents the Kenzan, and a stylus pen equipped with a 3D tracker resembles each flower stem. The users build the flower arrangement by selecting virtual flowers with adjustable length, whose position and orientation correspond to those of the pen, and then place the flowers by pressing the desired position on the trackpad. By using the trackpad and pen resembling the Kenzan and flower, respectively, TracKenzan provides an intuitive and straight­forward interface for users to practice Ikebana. We present the system implementation and evaluation tests conducted by 11 beginner and 7 experienced users, as well as one Ikebana teacher. They verified the sys­tem usability and capabilities as a learning tool for Ikebana.
