Abstract

The purpose of this study is to develop an mobile augmented reality for students to learn bar placing work, which is increasingly utilized in the construction field. In order to improve the understanding of the structural drawing, a structural drawing is used as a marker image, and an augmented reality is realized by superimposing a virtual 3D bar placing model that is placed according to the structural drawing on the screen. In addition to the 3D modeling, the contents are developed so as to help students to learn the interpretation method of 2D drawings, the development and splices of reinforcing steel, bar fabricating practice according to KCI structural concrete design code, and the process of bar placing. The results show that the augmented reality is positively evaluated in terms of interface style, perceived usefulness, perceived ease of use, perceived enjoyment, attitude toward using, and intention to use. The augmented reality is worth to be introduced because it has advantages of visualization and interaction in terms of education.

본 연구는 최근 건설분야에서 활용도가 높아지고 있는 증강현실 도구를 활용하여 학생들이 철근공사 배근작업을 학습할 수 있는 교육지원 컨텐츠를 개발하고 적용효과를 분석하였다. 구조도면에 대한 이해도를 높이기 위해 구조도면을 마커 이미지로 활용하였으며, 구조도면에 따라 배근된 가상의 3D 배근 모델을 화면에 겹쳐 표현하는 방식으로 증강현실을 구현하였다. 또한 3D 배근 모델과 함께 2D도면의 독도법, 이음 정착길이 기준, 부재별 구조설계기준에 따른 배근방법, 그리고 실제 배근하는 순서 등을 학습할 수 있도록 컨텐츠를 구성하였다. 적용결과 인터페이스 스타일, 지각된 유용성, 지각된 활용의 용이성, 지각된 즐거움, 활용 태도, 활용 의도 측면에서 긍정적으로 평가되었으며, 증강현실은 교육적 측면에서 시각화와 상호작용의 장점이 있기 때문에 활용가치가 높을 것으로 판단된다.
