혼합현실 기반 가상 인테리어 디자인 시스템

We are truly entering the era of ubiquitous computing due to development of computer hardware and network technology. The mixed reality technology is frequently utilized as a method of displaying information since it is possible to access information anytime, anywhere in the ubiquitous computing environment. The mixed reality includes the augmented reality that is used to integrate graphical objects and show those virtual objects in real environment. In this paper, a virtual interia design system is proposed while this system displays and chanes indoor interior materials of a building by using mixed reality technology in the ubiquitous computing environment. In general specific markers, on which virtual graphic objects is displayed, are attached to the physical environment in the augmented reality environment. But performance of that system has a lot of problems according to the number of markers and recognition rate. To resolve these problems various sensors are used in the ubiquitous computing environment and the relative distance to the position of a smart device such as a mobile phone and a PDA is measured. Then virtual graphic objects are arranged according to this information in the augmented reality. The augmented reality-based virtual interia design system proposed by this paper is composed of two part, hardware and application. The embedded hardware system receives data from all sort of sensors and the virtual interia design application display interia of a building according to the processed information. This system will be advanced if more research are achieved.
