Brain-Computer Interface Smashes Previous Record for Typing Speed
> A machine learning algorithm then decodes the brain patterns associated with each letter, and a computer displays the letters on a screen. The participant was able to communicate at about 90 characters, or 18 words, per minute.> 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.I had no idea average typing speed is this slow, though the extreme slowness of touchscreen typing is no surprise.
