Abstract

As display devices evolve, computer-based work environments are also becoming better suited to actual application tasks. This paper discusses the development of an architectural design system using the virtual table, which is a table-type projection system. It consists of the interactive VR modeler, the hybrid tracker and the architectural interpreter. The interactive VR modeler offers visual and tactile guide such as grid interaction, a tangible transparent prop and reference objects, so that a user can design architectural 3D models more easily and intuitively on the virtual table. The hybrid tracker includes two types of tracking methods for viewpoint according to the user's view and hand interaction: namely, vision-based tracking and magnetic tracking. The architectural interpreter automatically transforms simple 3D masses into a basic construction form that has architectural knowledge. The proposed system has advantage in the sense that it is suitable for collaboration among several users, allowing them to view graphical objects in stereoscopic view with direct 3D manipulation. Thus, it can be effectively used for architectural simulation and user-participated design.

디스플레이 디바이스가 발전함에 따라 컴퓨터를 이용한 작업 환경이 응용 목적에 보다 적합한 형태로 변환하고 있다. 본 논문에서는 테이블 형태의 프로젝션 시스템인 가상테이블을 이용하여 건축 디자인 시스템의 개발에 관하여 고찰한다. 개발된 시스템은 인터랙티브 VR 모델러, 하이브리드 트랙커, 건축용 인터프리터로 구성되어 있다. 인터랙티브 VR 모델러는 가상테이블 상에서 건축 디자인을 보다 쉽고 직관적으로 할 수 있도록 그리드 인터랙션, 텐져블 프랍, 참조 객체와 같은 비주얼 및 택타일 가이드를 제공한다. 하이브리드 트랙커는 사용자 시야각에 따른 임의의 뷰포인트를 제공하는 기능과 핸드 인터랙션을 위한 비전 기반 트랙킹과 마그네틱 트랙킹을 포함하고, 건축용 인터프리터는 간단한 삼차원 매스를 건축적 정보를 포함한 기본 구성요소로 자동 변환하는 기능을 한다 제안 시스템은 다수의 사용자가 공동 작업을 하기에 적절하며 입체적인 뷰를 통하여 그래픽스 객체를 삼차원 공간에서 직접 조작할 수 있다는 장점이 있다. 이와 같이 본 시스템은 건축 시뮬레이션 및 사용자 참여 디자인에 유용하게 사용되어질 수 있다.
