[comp.protocols.tcp-ip] interrupt-driven vs. polled I/O per

zweig@p.cs.uiuc.edu (04/26/89)

  A fascinating experiment (which has probably already been run somewhere)
about visual feedback and typing would be to have the computer *fix* errors
in typing before feeding back. That is, if I type "qiu" as the first part
of "quick", it'd be easy to repair it to "qui" before echoing the characters.
If you had users typing from dictation, it'd be almost trivial for the
computer to correct typos (since the correct text would already be known and
you'd just have to synchronize with the user's typing).
  What I wonder is this: would people make more/fewer typos, and how would
typos effect their speed? I, for one, always pause for about half a second
when I make a typo -- even if it only takes 2 keystrokes (~.25 sec) to
correct.
