This discussion "reading mind with computer" has finally
gotten at me. At least some of you bionet guys must be
living in California, has nobody ever heard of Biocontrol Systems, 
Inc. ? Dr. Hugh Lusted/Benjamin Knapp? BCS Biocontroller? BioMuse?


In November 1993, in the German iX (multiuser multitasking magazine),
brought an extensive article/interview with the developers (pp. 42-53).

There are using bioelectricity (EOG, EEG, muscle potential etc.)
pickup biofeedback as intuitive computer input device.

"Eye Controller" is an EOG based eye tracker. Eyecon is plugged in
into the RS232.

EOG/EEG is picked by a headband.

"Signal Processor" uses EMG for input.

Dave Warner at Loma Linda University Medical Center in Caly uses
BioMuse since 1991. He tells Crystal, an 18 month old (sic) was
immediately able to manipulate virtual things on screen. An adult
musician was equally capable to interact with musical software.
Dennis in "permanent vegetative state" after a heart stroke: eventually
he was able to communicate with some shoulder muscle EMG. All these
people were virtually immobile after some accidents they suffered.
Marc Degrout coupled BioMuse with Mime, a 3d gfx package. Now
a VR/BioMuse composite was possible. Andy, a paralyzed 10 year old could
control VR by cutting faces. Forward/reverse wheel chair switch
can be done with alpha/beta, which is simple to accomplish.

BCS Biomuse development system can bought for license (15 k$/25 k$).
Several car and air travel companies, Volvo at the front are
currently developing new security systems with BioMuse. AirForce
and Navy are using BioMuse. Auto Tanaka composed a 2 minute
solo for BioMuse named Kagami, which was featured by some news mag
on TV.

Brainman, Eyecon and Enabler (priced <$100) are targeted for
game market.

Eyecon, Enabler, Brainman and BioMuse RF are marketed 
Braincontrol, a Caly company. No German distributor at
time of print.

Stuff above is just some fragents from the article. I don't
know whether this company/products still exist. Nevertheless
I don't see any problems picking up bioelectricty with sensitive
opamps, processing signals with DSP to produce a realtime
output vector few bits wide, interfaced via RS232. I'm actually
amazed the technology still didn't hit the market.
