| >How is this a relevant comparison? 15 characters per minute is much less than the 15 WORDS per minute performance this work demonstrates 15 words from a set of 50 (6 bits per "word" vs. 5 per letter in the English alphabet). It's like saying a 100 baud telegraph machine can decode 300 words per second, just so long as those words come from the set of "dot" and "dash". >but decoding speech from the motor cortex has been much less understood than that of simple motor movements such as cursor position and velocity control. Cursor position and velocity are outputs, the input is still a self-paced motor imagery task. >Bravo-1 is the only subject they had. Fair cop. Maybe they'll get genuinely impressive results with their next patient. >This is completely, utterly false. See (https://stacks.stanford.edu/file/druid:jx921pv3255/Technical...) for survey of performance of typing BCI. I posted a link in a comment below showing an ITR of 35bpm from scalp EEG from pre-2010. >I have a completed PhD in invasive neuroprosthetics and still work in the field I am truly sorry for your loss. |
