Metaverse is closely related to brain-computer interface technology
What is brain-computer interface technology? How is the development of brain-computer interface technology now? What brain-computer interface technologies are there? How will brain-computer interface technology respond to us? Will the brain-computer interface become the entrance to the next generation of the metaverse? The brain-computer interface means that the human brain directly communicates with external devices, and the exchanged technology passes through the brain interface, and the information of the brain can be directly transmitted. So how does our brain normally exchange information with external devices? We illustrate with an example.
If the brain has information to transmit to the hand, it must first transmit the information to the hand through the motor nerve, and then use the hand to move the mouse or hit the keyboard, so as to transmit the information to the computer. The information of the computer must first be seen by our eyes, The ear hears, and then it is converted into electrical signals through the receptors in the eyes or ears, and then transmitted to the brain through the optic nerve or auditory nerve. With the brain-computer interface, we don’t have to be so troublesome, we can directly realize the information between the brain and the computer Exchange, before we understand the brain-computer interface, let's briefly review the development history of brain-computer interface.
In 1924, German doctor Hansberger recorded brain waves for the first time, which started the research on brain-computer interface technology; in 1969, a researcher named Fitz successfully let monkeys use thoughts to trigger the pointer of the instrument panel to rotate; 1973 In 2012, a professor at the University of California proposed the concept of brain-computer interface for the first time; at the opening ceremony of the World Cup in Brazil in 2012, an amputee disabled person scored the first goal with brain-computer interface technology and mechanical exoskeleton; in 2017, Facebook realized On the whole, brain-computer interface technology has developed rapidly in recent years, and has obtained preliminary results in some fields. At present, there are mainly three types of invasive non-invasive and semi-invasive invasive brain-computer interfaces.
The advantages of collecting EEG signals by implanting a motor into the brain are high signal quality, but the disadvantage is a safe non-intrusive brain-computer interface; EEG signals are collected outside the brain through devices such as brain wave helmets, which has the advantages of safety and disadvantages. The signal quality is not high, but the entry is a brain-computer interface. The EEG signal is collected by placing the motor in the area inside the skull and outside the meninges, and its safety or signal quality is in a medium difference. Because of the non-entry type, the security of the brain-computer interface is relatively strong, so the user's acceptance degree is relatively high, and the application prospect is relatively large. So what use does the brain-computer chassis technology have for us? It can be said that the brain-computer-shell technology will play a very important role in the improvement of human support.
In the short term, the brain-computer interface will significantly improve the quality of life of the elderly and the disabled, as well as improve human cognitive ability. It will play an extremely important role in medical health, management and education. In the long run, Brain-computer interfaces have revolutionized the way humans and devices, and humans and humans communicate, finding a consistent path for us, making it possible to immortalize consciousness in the digital world. So what does a brain-computer interface have to do with the metaverse? At present, the interface to the metaverse is mainly virtual reality glasses, that is, VR headsets, but the biggest disadvantage of VR headsets is that it is very inconvenient to wear them on the head, and brain-computer interface technology will make up for this major defect, and will It greatly enhances people's sense of integrity in the virtual world. The brain-computer interface gradually dissolves the boundaries between offline and online, reality and fantasy, reality and dream. The digital world and the physical world coexist, and a new civilization will be born.
Of course, the current brain-computer interface technology is still at a very early stage, and most of the research focuses on motor awareness, stimulus response to external stimuli, and a small amount of tactile experience. The collection, decoding and testimony of extremely complex human consciousness are still just icebergs One corner, but I believe that with the pull of demand and the further promotion of technology, brain-computer interface technology that can meet the needs of the metaverse will definitely appear.
