Another route might also be sub-vocalization[1], like TTS for your thoughts. I recently picked up some cheap toys to get started trying to emulate the results[2].
I agree! My PhD thesis is on this topic [1]. We’ve also done a very limited pilot test on a patient with ALS, with above random chance. Actual results may vary heavily on individual disease progression—the more motor recruitment that’s intact, the better.
I guess I'm just interested in more information. Do people who aren't NASA have this working? I am just learning this sci-fi feature from Ender's universe is possibly a reality, and if I can check it out, I want to.
TBH, other than the NASA resources, I'm building it from scratch. Goal would be to record the signal while prompting a user to say/think a subset of words. Afterwards the HOPE is that I will be able to train a simple- functional- model based on those inputs.
