Chinese researchers have announced the development of the world’s first two-way adaptive brain-computer interface (BCI), which promises to boost efficiency by 100-fold and bring the technology closer to practical everyday use.
In a study published by Nature Electronics, the scientists revealed that the system could eventually be integrated into portable and wearable BCI devices, making it suitable for consumer and medical applications.
Unlike traditional BCIs that decode the brain’s signals, this breakthrough allows the brain and device to learn from each other, ensuring stable performance over time. According to researchers from Tianjin University and Tsinghua University, this marks an important step towards mutual adaptation between biological and machine intelligence.
Co-author Xu Minpeng from Tianjin University stated, “Our work is the first to introduce the concept of brain-computer co-evolution and successfully demonstrate its feasibility, marking an initial step towards mutual adaptation between biological and machine intelligence.”
BCI technology has come a long way since its inception in the 1970s, when scientists first demonstrated that brain signals could be translated into commands for controlling machines with thoughts. While early research focused on assisting individuals with disabilities, today’s BCIs have expanded into various applications, from gaming wearable devices to hands-free drone control.
However, the one-directional nature of existing technology has limited the ability of BCI devices to provide feedback that helps the brain adjust and improve control over time. This limitation often leads to a decline in performance with extended use.
