Researchers have developed a new technology that can help read brain signals directly and may also aid people with movement disabilities to better communicate their thoughts and emotions. The technology involves a multi-electrode array implanted in the brain to directly read signals from a region that ordinarily directs hand and arm movements used, for example, to move a computer mouse.
The algorithms translate those signals and help to make letter selections.
“Our results demonstrate that this interface may have great promise for use in people as it enables a typing rate sufficient for a meaningful conversation,” said Paul Nuyujukian, postdoctoral student at Stanford University in California, US.
