VR / AR technology is not new to most people, but people have always had a bad impression of VR / AR-related entertainment products. For example, when experiencing VR technology, it is often accompanied by symptoms such as dizziness and dizziness. This is largely due to network delays. When the VR experiencer makes an action, the entire system will have a certain delay lag from monitoring the action to reflecting the motion into the VR field of view, and the audience will feel dizzy. 5G will be the best solution to the current poor VR / AR experience due to its low latency, large bandwidth, and large connections. It will further promote the development and progress of VR / AR communications.
What are the advantages of 5G technology?
Compared with 4G networks, the biggest advantages of 5G are large broadband, low latency, and large connections. Compared with the current 4G network, the fastest 5G network speed will be 100 times faster. The delay of 5G data transmission will not exceed 1 millisecond (compared to the current 4G network delay of about 70 milliseconds), and the data download The peak speed will be as high as 20Gb / s (4G is 1Gb / s). 5G has two characteristics in transmission: high bandwidth and high rate. Its peak theoretical transmission speed can reach 1GB every 8 seconds, which is hundreds of times faster than the transmission speed of the 4G network. Such transmission speed can effectively solve VR / AR content. , Especially the transmission problem of 8K and above UHD content. As long as it is under 5G environment, it takes only one minute to download or watch a Blu-ray-level, standard-length movie with related VR devices online, and it will also improve the embarrassing status of the audiovisual experience. The low-latency feature of the 5G standard also provides huge support for VR, a technology that is extremely sensitive to delay and will effectively solve the technical problem of the time delay of VR headsets.
5G technology enables the interconnection of intelligent things, realizes the communication between large-scale machines, and integrates with multiple VR / AR modes, bringing new experiences in different fields, such as VR live broadcast, VR / AR e-sports, AR medical, etc... With the landing of 5G, VR / AR will be connected with various industries to create greater business value.
Since VR (Virtual Reality) and AR (Augmented Reality) were invented, they have been regarded as transformative technologies that can completely subvert traditional human-computer interaction content.
What is VR technology?
VR is virtual reality, blocking the real world and creating a fully digital, immersive experience for users. Virtual reality technology mainly includes simulation environment, perception, natural skills, and sensing equipment. The simulated environment is a computer-generated, real-time, and dynamic three-dimensional realistic image. Perception means that the ideal VR should have the perception that all people have. In addition to the visual perception generated by computer graphics technology, there are perceptions of hearing, touch, force, movement, and even smell and taste, also known as multi-sensing. Natural skills refer to a person ’s head-turning, eyes, gestures, or other human behaviors. The computer processes the data appropriate to the participant ’s movements, responds to the user ’s input in real-time, and feeds back to the user ’s facial features. The sensing device refers to a three-dimensional interactive device.
Virtual reality is a combination of various technologies, including real-time 3D computer graphics technology, wide-angle (wide-field) stereoscopic display technology, tracking technology for the observer's head, eyes, and hands, as well as tactile / force feedback, stereo, network transmission, and voice input and output technology, etc.
What is AR technology?
AR is augmented reality, which has always been a hot word in the field of science and technology, superimposing digitally created content in the user's real world. Augmented reality technology is a new technology that integrates real-world information and virtual world information "seamlessly". It is physical information (visual information, sound, taste, touch, etc.), through computer and other scientific technologies, after simulation and superimposition, the virtual information is applied to the real world and is perceived by human senses, so as to achieve a sensory experience beyond reality. The real environment and virtual objects are superimposed on the same screen or space in real-time.
Augmented reality technology not only displays real-world information but also displays virtual information at the same time. The two kinds of information complement and superimpose each other. In the visual augmented reality, users use the helmet display to multiply the real world and computer graphics together, and then they can see the real world surrounding it.
5G helps the VR industry develop.
5G + VR is currently a common way of VR glasses. Based on VR glasses, ultra-high-definition VR content (on-demand or live broadcast) is transmitted through 5G, bringing an immersive, immersive, multi-dimensional entertainment interactive experience. It can also be used to experience 360-degree panoramic views without leaving home and is suitable for entertainment, media, movie theaters, sports, and other industries. VR is considered to be the next-generation computing platform, and its technology mainly includes aspects such as simulated environment, perception, natural skills, and sensing equipment. (1) In the entertainment industry, the main benefit of 5G is the VR game industry. Compared with mobile games and mobile games, the VR experience fully simulates the environment and has obvious advantages in creating "immersion". In the virtual world, VR breaks the "screen" concept of traditional games, making the "square" of the palm infinitely large, allowing players to appear in the game in person. (2) The application of VR in the media field in the 5G era is mainly based on the VR of new media, which has a stronger sense of immersion, interactivity, imagination, and intelligence.
