The future Metaverse has been proposed as a solution to various social problems, requiring new concepts. This evolution of the Metaverse will be geared toward solving real-world tasks by combining humans and machines in virtual and real spaces. This, in turn, necessitates the inclusion of additional human senses, including the tactile modality, to enable fully immersive human-machine and human-machine-human cooperation. The resulting challenges of communicating ultralow latency information below a 1 ms threshold have guided the Tactile Internet’s approaches to decrease various additive delay components. However, physically determined propagation delays geographically limit the future Metaverse when considering all human senses. We propose the concept of negative latency to address this limitation for the next evolution of the Metaverse that enables seamless and global user interactions. Our negative latency concept provides guarantees on predicted user actions to reduce perceived latency with high confidence. We evaluate a proof-ofconcept setup for grabbing tasks with a smart sensor glove and show that negative latencies of several hundred ms are attainable. Taking advantage of this and other advanced technologies in the Tactile Internet, we envision a truly global, immersive, and interactive Metaverse 2.0 that supports meaningful interactions between humans and machines.

触觉互联网中的负延迟作为全球元宇宙沉浸的推动者


未来的元宇宙被提出作为各种社会问题的解决方案，需要新的概念。元宇宙的演变将致力于通过在虚拟和现实空间中结合人类和机器来解决现实世界的任务。反过来，这需要纳入额外的人类感官，包括触觉方式，以实现完全沉浸式的人机合作和人机人合作。由此产生的低于 1 毫秒阈值的超低延迟信息通信挑战已指导触觉互联网减少各种附加延迟组件的方法。然而，在考虑所有人类感官时，物理决定的传播延迟在地理上限制了未来的元宇宙。我们提出负延迟的概念，以解决元宇宙下一步发展的这一限制，从而实现无缝的全球用户交互。我们的负延迟概念为预测的用户操作提供了保证，以高置信度地减少感知延迟。我们评估了使用智能传感器手套抓取任务的概念验证设置，并表明可以实现数百毫秒的负延迟。利用触觉互联网中的这一技术和其他先进技术，我们设想了一个真正的全球性、沉浸式和交互式元宇宙 2.0，支持人与机器之间有意义的交互。
