Web Real-Time Communication (WebRTC) is an open-source technology which enables remote peer-to-peer video and audio connection. It has quickly become the new standard for real-time communications over the web and is commonly used as a video conferencing platform. In this study, we present a different application domain which may greatly benefit from WebRTC technology, that is virtual reality (VR) based surgical simulations. Virtual Rotator Cuff Arthroscopic Skill Trainer (ViRCAST) is our testing platform that we completed preliminary feasibility studies for WebRTC. Since the elasticity of cloud computing provides the ability to meet possible future hardware/software requirements and demand growth, ViRCAST is deployed in a cloud environment. Additionally, in order to have plausible simulations and interactions, any VR-based surgery simulator must have haptic feedback. Therefore, we implemented an interface to WebRTC for integrating haptic devices. We tested ViRCAST on Google cloud through haptic-integrated WebRTC at various client configurations. Our experiments showed that WebRTC with cloud and haptic integrations is a feasible solution for VR-based surgery simulators. From our experiments, the WebRTC integrated simulation produced an average frame rate of 33 fps, and the hardware integration produced an average lag of 0.7 milliseconds in real-time.

Web实时通信(Web Real-Time Communication, WebRTC)是一种开源技术，可以实现远程点对点视频和音频连接。它已迅速成为网络实时通信的新标准，通常用作视频会议平台。在这项研究中，我们提出了一个不同的应用领域，这可能会极大地受益于WebRTC技术，即基于虚拟现实(VR)的手术模拟。虚拟肩袖关节镜技能训练器(ViRCAST)是我们的测试平台，我们完成了WebRTC的初步可行性研究。由于云计算的弹性提供了满足未来可能的硬件/软件需求和需求增长的能力，因此ViRCAST部署在云环境中。此外，为了进行合理的模拟和交互，任何基于vr的手术模拟器都必须具有触觉反馈。因此，我们实现了一个用于集成触觉设备的WebRTC接口。我们在谷歌云上通过触觉集成的WebRTC在各种客户端配置下测试了ViRCAST。我们的实验表明，云和触觉集成的WebRTC是一种可行的基于vr的手术模拟器解决方案。从我们的实验中，WebRTC集成模拟产生的平均帧速率为33 fps，硬件集成产生的实时平均延迟为0.7毫秒。
