I played a bit with Emotiv and find a maximum of one character-per-second pretty believable—at least, if you stick to actual brain signals and not signals from face muscles ( and even with face muscles one character per second seems in the right ballpark).
One character is not the same as one byte of (maximally compressed) information. The whole point of programs like Dasher (and word suggestion features in general) is to take advantage of the low entropy of text data relative to its uncompressed representation. Characteristic screenshot
Were you using a static, non-adaptive, on-screen keyboard? If so, that’s why I would think connecting it to Dasher should result in a speed greater than one char per second, at least after the training period (both human training, and character-probability-distribution training).
