Abstract

Despite the wide range of information and engineering visualization techniques available, studies in investigating the effectiveness of the techniques in visualization has been rare. The typical visualization techniques were CAD, 2D and 3D computer graphics, and virtual environment (VE) that use 3D displays of 3D. space. The objects of this study is to analyze the user preferences and workload changes according to the visualization methods of engineering drawings such as 2D CAD, 2D computer graphics, 3D computer graphics, and augmented reality which is a variation of VEs. The results showed that users preferred 3D visualization techniques to 2D visualization techniques, though there were no workloads differences. Furthermore, the 3D perspective of AR which analogies the real world could facilitate the interpretation of engineering drawings.

엔지니어링 정보와 같은 3차원 정보의 시각화에는 CAD, 2D 컴퓨터그래픽, 3D 컴퓨터그래픽, 가상현실(VE)을 이용한 3차원적 표현 등 다양한 정보표현방식이 이용될 수 있으나, 이들 방식의 효과에 대한 비교연구는 매우 부족하다. 본 연구의 목적은 CAD, 2D 컴퓨터그래픽, 3D 컴퓨터그래픽, 가상현실의 한 형태인 증강현실 방식(AR)의 정보표현 방식에 대한 사용자의 호의도 및 심리적, 신체적 업무부하의 차이를 비교하는 것이다. 실험결과 사용자들은 정보제공방식 간에 업무부하의 차이는 없다고 보고하였으나, 2D 정보표현보다 3D 정보표현을 선호하였다 우리가 물체를 인식하는 방식과 동일한 방식으로 정보를 제공하는 AR방식은 인식정보의 병렬처리를 통하여 엔지니어링 정보제공에 유용한 수단으로 사용될 수 있음을 보여 주었다.
