INTRO: For the first time ever a team of researchers says it has deployed a brain-computer interface (or BCI) to decode the neural signals that represent the writing of letters and turn them into text. A 65-year-old man paralyzed from the neck down showcased the BCI, which allowed him to write 90 characters per minute. Or approximately double the previous record for “writing” with a brain-computer interface.
Science Alert reported on the brain-computer interface breakthrough, which the researchers outlined in a paper published in the journal Nature. The researchers, working at BrainGate—a nonprofit consisting of neuroscientists, engineers, and the like—have the ultimate aim of helping paralyzed people. Specifically by restoring their ability to communicate. As well as by enhancing their independence in the absence of physical movement.
Earlier BrainGate research related to turning thoughts of writing into text focused on using neural patterns related to arm movements. Meaning that, previously, machine learning algorithms would decode neural signals of arm movements—gleaned from implanted sensors in the brain—in order to turn them into the movements of a mouse cursor. In turn allowing a BCI user to click on letters on a computer screen in order to write out words. This new system, however, focuses on the actual writing of individual letters... (MORE - details)
