With the rapid development in the areas of multisensory hard- and software and the emergence of Tactile Internet, new media such as haptics, smell, olfaction, etc., nowadays, play a prominent role in making virtual objects physically tangible in a collaborative and/or networked virtual environment. By allowing users to feel each other's presence and physically manipulate objects from their interacted environments within 1 ms. The Tactile Internet facilitates fast multimodal interactions with multisensory information over the 5G network. 1 ms is a critical threshold in human perception of tactile response. For auditory response, this threshold is 100 ms and for visual response, it is 10 ms, which means delays above these thresholds are within the latency limit sensed by the human brain. In 4G, the round trip latency is 25 ms for an ideal environment. Clearly, that indicates 4G is not able to meet the requirements of tactile response. For this reason, the efforts to reduce latency in 5G are critical for Tactile Internet. Low-latency communications will also enable other digital twins’ applications such as real-time control of smart grid, self-driving car, and so on.

多媒体和触觉互联网

随着多传感器硬件和软件领域的快速发展以及触觉Internet的出现，如今，诸如触觉，嗅觉，嗅觉等新媒体在使虚拟对象在协作和/或物理上切实可见的过程中发挥着重要作用。或联网的虚拟环境。通过允许用户感觉彼此的存在并在1毫秒内从其交互环境中物理操纵对象。触觉互联网促进了通过5G网络与多感官信息的快速多模式交互。1毫秒是人类感知触觉反应的关键阈值。对于听觉响应，此阈值为100毫秒，对于视觉响应，此阈值为10毫秒，这意味着高于这些阈值的延迟在人脑感知的延迟范围内。在4G中 对于理想的环境，往返延迟为25 ms。显然，这表明4G无法满足触觉响应的要求。因此，减少5G延迟的努力对于触觉互联网至关重要。低延迟通信还将支持其他数字双胞胎的应用，例如智能电网，自动驾驶汽车的实时控制等。
