Abstract

Recently, realistic contents such as virtual reality(VR) and augmented reality (AR) are widely used for education to provide beneficial learning environments with thee-dimensional(3D) information and interactive technology. Specially, AR technology will be helpful to intuitively understand by adding virtual objects registered in the real learning environment with effective ways. In this paper, we developed an AR learning system using 3D spatial information in the 2D based textbook for studying math related to geometry. In order to increase spatial learning effect, we applied to solid shapes such as prisms and pyramids in mathematics education process. Also, it allows participants to use various shapes and expression methods (e.g., wireframe mode) with interaction. We conducted the experiment with our AR system, evaluated achievement and interest. Our experimental study showed positive results, our results are expected to provide effective learning methods in various classes through realistic visualization and interaction methods.

최근 교육의 학습 효과에 도움을 제공하기 위해 실감 콘텐츠 환경에서 상호작용을 제공하는 시스템이 널리 활용되고 있다. 특히, 증강현실(Augmented reality) 기술은 실제 학습 환경에 가상의 물체를 합성하여 정보를 직관적으로 이해하는데 도움을 제공할 수 있다. 본 논문에서는 기하와 관련된 입체도형에 대한 수학개념을 3차원의 공간 정보를 이용하여 학습하는 증강현실 도구를 개발하였다. 이를 위해 수학 교육 과정 중 각기둥과 각뿔에 관한 교과서에 증강현실 합성 기술을 적용하여 공간적인 학습 효과를 보다 높일 수 있도록 하였다. 또한, 카메라와 마커 사이의 위치 관계에 의해 정합이 되도록 가상의 도형을 표현하였고, 공간에 대한 지각 효과를 높이기 위해 평면도, 전개도 등 도형 형태의 다양화, wireframe 가시화 모드 선택 기능 등이 가능하도록 하였다. 본 논문에서 제시한 증강현실 기반 학습도구를 통해 수업에 관한 학업성취도 및 흥미도에 관한 효과성을 평가한 결과 통계적으로 유의한 결과를 얻을 수 있었다. 본 논문에서 제안한 방법을 통하여 입체도형 학습 뿐 아니라 다양한 수업에서 교육적 효과를 높일 수 있을 것으로 전망한다.
