Virtual Reality (VR) has shown great potential to revolutionize the market by providing users immersive experiences with freedom of movement. Compared to traditional video streaming, VR is with ultra high-definition and dynamically changes with users’ head and eye movements, which poses significant challenges for the realization of such potential. In this paper, we provide a detailed and systematic survey of enabling technologies of virtual reality and its applications in Internet of Things (IoT). We identify major challenges of virtual reality on system design, view prediction, computation, streaming, and quality of experience evaluation. We discuss each of them by extensively surveying and reviewing related papers in the recent years. We also introduce several use cases of VR for IoT. Last, issues and future research directions are also identified and discussed.

通过为用户提供身临其境的移动自由体验，虚拟现实（VR）已显示出巨大的潜力来革新市场。与传统的视频流相比，VR具有超高清技术，并且会随着用户的头部和眼睛的移动而动态变化，这对于实现这种潜力提出了重大挑战。在本文中，我们提供了对虚拟现实的支持技术及其在物联网（IoT）中应用的详细而系统的调查。我们确定了虚拟现实在系统设计，视图预测，计算，流传输和体验质量评估方面的主要挑战。近年来，我们通过广泛地调查和审查相关论文来讨论它们中的每一个。我们还将介绍用于物联网的VR的几个用例。持续，
