The transmission and safeguarding of intangible cultural heritage (ICH) follow an apprenticeship manner for education. However, people have problems that cannot continue to implement education because of time, space, economic and environmental constraints. Utilizing information and communication technology (ICT), these problem can be settled. Particularly, in this paper, we propose a novel 3D hand motion recording framework to record the motions of the craftsperson in the ego-centric view using Leap-motion vision sensors. In contrast to the existing 3D hand motion recording frameworks, we adopt a head-mounted Leap Motion for recording the ego-centric view of handcraft motions and use the other Leap Motion to solve the problem of severe self-occlusions between the fingers. For the target content for recording, we select Nubi, which is a traditional sewing technique in Korea, and a Nubi craftsperson is designated as the ICH of Korea. From the preliminary experiments, we confirm that the proposed framework can be applied to recording the various sewing hand motions effectively.
