Chinese researchers are using AI algorithms to translate brain signals into real-time indicators, allowing users to control computer inputs with their mind -- and even control the motion of a wheelchair.
Scientists at Zhejiang University's State Key Laboratory of Brain-Machine Intelligence are making significant strides in the area, known as brain-computer interface (BCI) technology.
The emerging field holds particular promise for healthcare applications. The Hangzhou-based laboratory is exploring both invasive and non-invasive approaches to help patients with physical disabilities and other conditions.
"Our lab primarily researches brain-computer interfaces, including invasive and non-invasive BCIs. We mainly study how to use artificial intelligence technologies to read and control the brain, and how to achieve mutual enhancement between computers and the human brain," said Wang Jiquan, a research fellow at the laboratory.
The lab has developed wearable EEG headbands capable of monitoring attention levels in real time. During a demonstration with a China Global Television reporter wearing the device, the technology detected an instant drop in concentration when the reporter's focus shifted.
The reporter was also able to sit in a wheelchair and control it using only mental commands, including forward motion and turning at will.
According to Wang, the widespread dispersion of these wheelchairs and other thought-controlled devices could transform the livelihoods of patients all over the world.
"In real life, BCI technology could help many people, including those with physical disabilities, mental health conditions, or other illnesses, enabling them to live better lives," he said.
Researchers said the next challenge involves transitioning BCI technology from laboratory settings to safe, reliable everyday use. The objective, they emphasized, is not to replace human capabilities but to expand the ways in which minds interact with the world.
