초록
확장현실(XR: Extended Reality)은 가상현실, 증강현실, 혼합현실을 포괄하는 용어로, 표준화된기술로서 사용된다. 가상현실의 경우 일반적으로 HMD(Head Mounted Device)를 사용하여 체험하는 것이 일반적이다. 그러나 HMD를 사용할 수 없거나 어지러움을 느끼는 사용자들은 접근성이떨어지는 문제가 있다. 본 연구에서는 3차원 가상현실 체험에서의 불편함을 최소화하고 누구나체감형 서비스를 이용할 수 있는 하이브리드형 WebXR 서비스를 제안했다. 하이브리드형 2-Way 이용방법은 PC 기반의 체험을 위한 WebGL을 활용한 서비스와 HMD를 사용한 가상현실 서비스인 WebXR을 동시에 체험할 수 있는 방식을 연구했다. 또한, 기존의 가상현실 콘텐츠 서비스는HMD 장치 내부에 프로그램을 설치해야 하는 불편함을 해소하기 위해 웹 기반으로 구현하여 어떤 장치에서든 서비스할 수 있도록 했다. 또한, 제안된 방식은 HMD를 사용할 수 없는 사용자들을 위해 360 파노라마를 통한 WebXR 서비스를 제공하여 사용자의 접근성을 극대화했다.
Abstract
Extended Reality (XR) is a standardized technology encompassing virtual reality, augmented reality, and mixed reality. In virtual reality, it is common to use a Head Mounted Device (HMD) for the experience. However, this poses accessibility challenges for users who cannot use an HMD or experience discomfort, such as dizziness. In this study, we propose a hybrid WebXR service that minimizes discomfort and provides an immersive experience for everyone in 3D virtual reality. The hybrid 2-Way approach allows users to simultaneously experience PC-based WebGL interactions and immersive HMD-based virtual reality services through WebXR. Furthermore, to overcome the inconvenience of installing programs within HMD devices, we implement the proposed method using web-based technology, enabling device-independent services. Additionally, we maximize user accessibility by offering WebXR services through 360 panoramas for users without access to an HMD.
