The ancient art of handwriting has just pushed the field of brain-computer interface (BCI) to the next level. Researchers have devised a system that allows a person to communicate directly with a computer from his brain by imagining creating handwritten messages. The approach enables communication at a rate more than twice as fast as previous typing-by-brain experiments. Researchers at Stanford University performed the study on a 65-year-old man with a spinal cord injury who had had an electrode array implanted in his brain. The scientists described the experiment recently in the journal Nature.
By comparison, able-bodied people close in age to the study participant can type on a smartphone at about 23 words per minute, the authors say. Adults can type on a full keyboard at an average of about 40 words per minute.
