초록
본 연구는 PC 및 VR 디바이스를 이용하는 사용자가 리모트 환경에서 데이터 시각화를 협업 분석할 수 있는 시스템을 개발한다. 시스템에서는 사용자들이 시각화 분석의 프로세스 이해를 돕고 역할 분담을 효과적으로 할 수 있도록 업무 지향(task-oriented) 형식의노드-링크제어인터페이스(node-link control interface)를제공한다. 또한, 다수의사용자가물리적으로공간이 분리되어도 협업을 진행하여 시각화 분석의 피드백을 받을 수 있는 네트워크 환경을 제공한다. 시스템에서 진행하는협업 분석 방식을 설명하기 위해 시나리오를 설계하였다. 그리고 관련분야 전공자를 대상으로 시스템의 사용성을 측정하는파일럿 실험을 진행하였다. 실험 결과 확장현실 공간에서 이해하기 쉬운 형식의인터페이스 조작을 통해 데이터를 자유롭게분석할 수 있고, 리모트 환경에서도 실시간으로 협업 분석을 수월하게 진행할 수 있음을 확인하였다.
Abstract
This study aims to develop a system that enables users employing PC and VR devices to collaboratively analyze data visual- izations in a remote environment. The system provides a task-oriented node-link control interface to aid users in understanding the visualization analysis process and effectively distributing roles. Additionally, it offers a network environment where multiple users can collaborate and receive feedback on visualization analysis even when physically separated. To elucidate the collab- orative analysis method implemented in the system, we designed a scenario. Furthermore, we conducted a pilot experiment to evaluate the system’s usability with participants majoring in related fields. The experimental results confirmed that users can freely analyze data through easily comprehensible interface manipulations in an extended reality space, and efficiently conduct real-time collaborative analysis in a remote environment.
