Abstract

A virtual science experience space(VSES) using virtual reality technology including haptic device is proposed to overcome limits which the existing science education has and to improve the effect of it. Four example scientific worlds such as Micro World, Friction World, Electromechanical World and Macro World are demonstrated by the developed VSES. Van der Waals forces in Micro World and Stick-Slip friction in Friction World, the principle of induction motor and power generator in Electromechanical World and Coriolis acceleration that is brought about by relative motion on the rotating coordinate are modeled mathematically based on physical principles. Emulation methods for haptic interface are suggested. The proposed VSES consists of haptic device, HMD or Crystal Eyes and a digital computer with stereoscopic graphics and GUI. The proposed system is believed to increase the realism and immersion for user.

본 논문에서는 과학 교육 분야에서 기존의 교육방식이 갖고 있는 한계성을 극복하고 교육 및 학습 효과를 향상시키기 위한 방안으로 역감 제시 장치를 이용한 가상 현실 시스템을 제안한다. 제안된 시스템의 효용성과 응용가능성, 활용방법을 효과적으로 나타낼 수 있는 4가지 과학세계로 구성된 가상 과학 체험 공간을 구축하여 미시 세계에서는 원자간의 현상을, 마찰 세계에서는 스틱-슬립 마찰현상을, 기전 세계에서는 모터 및 발전기의 원리를, 거시 세계에서는 코리올리스 가속도로 인한 물리적 현상을 각 세계에서 역학적으로 모델링하고 역감 제시 장치와 인터페이스를 위한 에뮬레이션 기법을 고안한다. 그리고, 역감 제시 장치, HMD(Head Mounted Displays), 가상환경(스테레오 그래픽스와 GUI)을 포함한 디지털 제어기로 구성된 가상 과학 체험 시스템을 구축한다. 끝으로 본 연구를 통해 교육의 보조 매체와 학습의 도구로서 효율성을 극대화시키기 위한 가상 과학 체험 공간의 설계 및 구현에 관한 고려사항을 제시한다.
