   once we discussed chord keyboard and since then i have read more than
ten related papers.  the most recent paper i read was published in 1978.
although many papers claim that chord kbd may be faster than tratitional
kbd (e.g., querty, dvorak), I have not seen any ACTUAL EXPERIMENTAL data
supporting such a claim.  in most cases, the difference in speed was
negligible.


   1.  i wonder if any related paper has been publshed after 1978.
I would like to get a list.   
   
   2.  Does any paper show an actual experimental data supporting the
claim that chord kbd is much faster than traditional one?

   thanks in advance.  please e-mail to me.

    It is not, for fully trained chord-typists, that is.  The increase
    in speed is very significant, upwards of 200%

    There are no such things as "generic chord keyboards" as implied
    by your question; there are only function-specific ones and no two
    are alike.  The chord-keyboard applications that I've seen include:
    coding of machine-readable address-strips on envelopes in a high-
    speed postal sorting machine; real-time transcription in the court
    of law & parliament (replacement for stenographing machines) and
    the most promising of all: television-subtitling in real-time!
    The latter technology, originally developed by the BBC in the UK
    (for teletext applications), uses a special syllabic-chord keyboard
    that promises to make simultaneous transcription of spoken words an
    everyday commodity.

    There has been a number of articles about chord-keyboards in the
    Brittish ergonomy/ related magazines.  Try browsing the last
    couple of volumes of "Applied Ergonomics" (UK); shouldn't be hard
    to find.
