At the 2023 Zhongguancun Forum, brain computer interface once again became one of the hot topics. This technology of driving a certain device through "ideas" would have been described as "fantasy" or even "magic" if proposed ten years ago. Nowadays, products for practical applications of brain computer interfaces have appeared in this forum. The ability to monitor the wearer's mental state makes the helmet safer. In short, it establishes a direct connection pathway between the human brain and external devices, allowing the brain to engage in a "conversation" with the machine. This kind of segment, which seems to only appear in science fiction movies, has now attracted a considerable number of enterprises in China and has transformed some of their achievements into practical commercial applications. In the exhibition area of the 2023 Zhongguancun Forum, multiple domestic brain computer companies including Borikon, Huanao Technology, Rouling Technology, and Zhentai Intelligent brought their own products, including brain controlled typing systems, brain controlled rehabilitation devices, sleep assisted brain computer devices, and safety helmets that can monitor the wearer's mental state. In the brain controlled typing experience area, the staff puts on a hood covered with metal sheets and focuses on the simulated keyboard. The corresponding letters they want to type will appear on the page. It's similar to the device used by Hawking, but Hawking's device is an eye control, and this one is a brain control, truly 'mind control', "said a staff member at Borecon. However, compared to the cool "mind typing", other brain computer applications have already made some people feel the power of technology. Through a safety helmet, the backend can monitor multiple indicators such as fatigue, focus, and alertness, which is very helpful for production safety. "Tang Zaixi, founder of Huanao Technology, said," It will mainly be applied to some high-risk and tightly sealed industries. Real time reminders for staff safety can also avoid hidden dangers caused by fatigue operations. "Currently, this system has been used in the construction of Beijing Metro No. 13, In the future, it will also be applied to areas such as highway construction and coal mining in Tibet. In addition, the "unmanned search and rescue brain controlled multi domain robot system" proposed by Beijing University of Technology can be applied in disaster search and rescue scenarios. Brain control rehabilitation equipment has been put into use in multiple hospitals, and more applications of brain computer interfaces are still in the medical field. The reporter from Beijing Youth Daily experienced the equipment to help stroke patients recover their limb movement ability at the exhibition site. As long as you wear a headband similar to a hair clip, place several metal patches on your forehead, and then wear gloves connected to several cables, you can imagine yourself frying eggs and catching butterflies as demonstrated in the recovery software. The reporter from Beiqing Daily only saw the clenching movements displayed on the screen, and before they could put on their gloves, they curled up on their own. This is the response that the device captures the 'clenching' signal emitted by the brain and transmits it to the training gloves. "" This is driven by brain waves. "The staff of Zhentai Intelligent, who brought the device, said that the limbs of patients with brain injury are healthy, and the nerves that transmit the signal are damaged. The significance of this device is to train the brain to issue commands and make muscles produce related movements, To stimulate the patient's damaged or other nerves and help them recover to a certain extent
