在本文中，我们提出了我们正在进行的网络虚拟现实项目的初步结果，通过讨论网络触觉游戏的实现和性能。在这个游戏中，在线玩家感觉像是在处理一个真实的篮球，因为他们能够通过使用触觉界面来感受触觉。在这种实现中的一个具有挑战性的问题是触觉数据传输通过互联网，允许在线多用户玩。由于触觉信息是非常敏感的延迟和抖动，提供及时的传输是至关重要的。我们进行实验，比较使用UDP（用户数据报协议）和TCP（传输控制协议）时的触觉数据传输的性能，并观察到UDP和TCP都不能满足QoS（服务质量）的触觉传输的要求。作为进一步的研究，我们计划调查一些替代的触觉数据传输方案。
In this paper, we present preliminary results of our ongoing networked virtual reality project by discussing the implementation and performance of a networked haptic game. In this game, online players feel like handling a real basketball since they are able to feel the sense of touch by using haptic interfaces. One of challenging issues in this implementation is haptic data transmission over the Internet to allow online multi-user play. Since haptic information is extremely sensitive to delay and jitter, the provision of timely transmission is critical. We carry out experiments to compare the performance of the haptic data transmission when using UDP (User Datagram Protocol) and TCP (Transmission Control Protocol), and observe that neither UDP nor TCP is able to satisfy QoS (Quality of Service) requirements of the haptic transmission. As a further study, we plan to investigate some alternative haptic data transmission schemes.
