Typing at 60 words/minute, 5 characters/word and 8 bits/character gives a gross bit rate of 40 bits/second. Of course, the information rate is a lot less, since there are fewer than 8 bits of information per character in English. The paper says "from 4.8 bits per syllable for Basque to 8.0 bits per syllable for Vietnamese" and there are multiple characters per syllable. So the typing information bit rate is probably somewhere around 10 to 15 bits/second.
