触觉互联网将使用户能够亲自探索遥远的环境，并使他们的技能跨越距离。在这种情况下，一个重要的技术方面是触觉信息的获取、压缩、传输和显示。在本文中，我们介绍了触觉互联网的触觉编解码器设计的基本原理和最新进展。讨论涵盖了动觉数据还原和触觉信号压缩两种方法。我们特别关注如何利用人类触觉感知系统的局限性对动觉和触觉信息进行有效的感知编码。本文进一步讨论了音频和视频与触觉信息的多路复用以及触觉通信解决方案的质量评估。最后，我们描述了正在进行的IEEE标准化活动P1918.1.1的现状，该活动的目标是标准化第一套编解码器，用于跨通信网络的动觉和触觉信息交换。
The Tactile Internet will enable users to physically explore remote environments and to make their skills available across distances. An important technological aspect in this context is the acquisition, compression, transmission, and display of haptic information. In this paper, we present the fundamentals and state of the art in haptic codec design for the Tactile Internet. The discussion covers both kinesthetic data reduction and tactile signal compression approaches. We put a special focus on how limitations of the human haptic perception system can be exploited for efficient perceptual coding of kinesthetic and tactile information. Further aspects addressed in this paper are the multiplexing of audio and video with haptic information and the quality evaluation of haptic communication solutions. Finally, we describe the current status of the ongoing IEEE standardization activity P1918.1.1 which has the ambition to standardize the first set of codecs for kinesthetic and tactile information exchange across communication networks.
