3D 입체영상을 활용한 활동관찰이 협응 동작학습에 미치는 영향

Abstract

Previous studies have used 2D images as a means of action observation methods. Due to the development of computer and video technology, however, 3D stereoscopic images have emerged and used in research. The purpose of this study was to investigate the effect of action observation with different types of visual feedback on coordinated movement learning. Sixteen individuals who had no experience in dance participated in the study. They practiced a whole-body coordinated pattern for 3 days using either 2D plane images or 3D stereoscopic images of Cucaracha dance movement. The results indicated that the magnitudes and angles of movement for each variable in 3D group tended to show higher values than 2D group. Thus, action observation using 3D stereoscopic images showed a tendency that such method has a positive effect on learning of coordinated movement, even though there was no statistical difference. Future studies need to be conducted considering the setting of the exercise period for the complexity of the task in action observation for motor skill learning.
