Re: Observation about group

There was a professor in the seventies that did the same thing, pre-Apple II,
but instead of voice, he used recorded brain-waves.  The controller would think
a command and the computer would compare the controller's brainwave patterns to
patterns stored in memory and then try and figure which one was closest to the
command that was now being received.  The result was to position an outside,
motorized camera that scanned a portion of the campus.  This was pretty
unexacting work back then, requiring five recorded examples for each command
because each one was slightly different when recorded.

	I did some checking on the prof. back in the early 80's.  He had left academia
and was on the board of directors for a cybernetics firm.

<< That's exactly how the speech recognition card that Steve Circia
designed and published in Byte magazine in his column Circia's Circuit
Cellar worked.  I've always wanted to track down that article and
build one of those cards and maybe expand on it.  It is a very simple
design in that you simply record yourself saying something and it
compares whatever it hears with what it has recorded.  It could record
up to 64 samples and when it found a match it would send a single
character or string to the Apple II so you could say catalog and it
would send the text "CATALOG" followed by carriage return to the Apple
II.
