Advancement In Crafts Documentation By Using 4D Motion Recording Method

The Cultural Heritage Administration of Korea has been conducting the national intangible cultural heritage record projects since 1995 to preserve records according to environmental changes systematically.

This project manages the holder's technical and artistic skills and records the craftsmen's method in detail. The sources such as photos(2D), video(3D), and sound are acquired for the project.

In particular, it is possible to lay the foundation for transmitting intangible heritage, which is in danger of being cut off, to the next generation, contents such as virtual, augmented reality, and metaverse, and future-oriented transmission education by recording the movements of artisans in crafts.

Recently, the research based on techniques such as marker and markerless optical sensors, inertial sensors, and muscle sensors has been conducted to record deep 4D motion domestically and internationally.

The following methods are proposed for the advancement and effective use of movement records.

1) It is necessary to carry out a 4D movement recording project for the use of virtual, augmented reality with a higher sense of depth and realism than a photo and video recording.

2) Select a motion sensor suitable for the characteristics of the craft event, and record the motion using the multi-view multi-sensor.

3) Ego-centric view movement record is performed which is suitable for the latest content platforms such as virtual reality and augmented reality.

4) Develop educational content for professional educators beyond intangible heritage experience contents.

5) In addition to recording movements, contextual information such as tools for intangible heritage crafts, the site, and the process of changing the objects of production is mainly recorded.
