A few minutes ago, I followedup mentioning the MicroWriter as the only
chord keyboard I've encountered, and mentioning it is typically half
as fast to use as eg a QWERTY keyboard; thinking again, I realised
that there are also braille-machine keyboards (six "dot" keys - 3 for
each hand; a space key in the middle; and new-line on one side,
backspace on the other (I think) for the little fingers). These are
also about half qwerty speed, for an experienced user.
Aside: there is also a "braille shorthand" machine, writing onto paper
tape for note-taking; the key arrangement is the same, but there is a
strange extra feature: the length of the paper advance after each
character depends on how fast the keys are released. Individual users
develop their own abbreviations using this (I don't know whether there
are any standard abbreviation systems using the character spacing.)
