Abstract

VR(Virtual Reality) and AR(Augmented Reality) devices are becoming more common, and the need for proper contents presentation techniques in such environments has been growing ever since the popularization of the devices. One of the contents is the spatio-temporal data, which has become more prominent since it could be both generated and consumed by a large number of ordinary users. In this work, the researcher analyzed the characteristics of spatio-temporal data as a source for visualization in VR and AR environment, and categorized prior visualization methods for such data, which were devised for traditional monitors. The researcher also reviewed the hardware specification of state-of-the-art devices, and examined the possibility of adopting the previous visualization approaches. This work is expected to contribute in designing spatio-temporal visualization for VR and AR environment by utilizing their unique characteristics.

가상 현실(Virtual Reality) 및 증강 현실(Augmented Reality) 기기가 보급되면서 새로운 환경에서의 콘텐츠 제공 기술 연구에 대한 필요성이 증대되고 있다. 특히 해당 환경에서 제공할 수 있는 다양한 컨텐츠 중에서도 사물 인터넷(Internet of Things) 기기의 대중화로 인하여 다수의 일반 사용자들이 생산하고 활용하는 시공간 데이터가 증가하고 있다. 본 연구에서는 시공간 데이터에 대한 VR 및 AR 환경에서의 시각화를 위하여 먼저 데이터의 특성을 분석하였고, 일반 모니터를 사용하여 진행되었던 기존 연구에서의 시각화 기법들을 특성에 따라 분류하였다. 이를 통해 최신 기기의 사양 및 상호 작용 설계에 있어서의 특성을 반영하여, 기존 시각화 기법들의 차용 가능성을 살펴보았다. 본 연구의 결과를 통해 VR 및 AR 기기의 특성에 맞춰 시공간 데이터 시각화를 설계할 수 있을 것으로 기대된다.
