Pursuing a viable alternative to invasive brain-computer interfaces (BCIs) has been a continued research focus of Carnegie Mellon University's He Lab. In 2019, the group used a noninvasive BCI to successfully demonstrate, for the first time, that a mind-controlled robotic arm had the ability to continuously track and follow a computer cursor.
As technology has improved, their AI-powered deep learning approach has become more robust and effective. In new work published in PNAS Nexus, the group demonstrates that humans can control continuous tracking of a moving object all by thinking about it, with unmatched performance.
