The problem is there is no large revenue stream from such technologies.

There aren't that many disabled people in the world to cover the cost 
of R&D, so unless the technology can be put into the hands of 
hundreds of millions instead of millions, it hasn't had the chance to avail.

And Roger, you are right.  It's not new.  I was working with brain 
wave remote control using non affixed transducers in the 1980's 
:)  But a $50,000 R&D cost prevented me from taking my development 
any further and that was at it's most infant.  To really bring it to 
market about $4 million would be required and there just weren't 
enough disabled people to fork out to cover it.

So it got put on the side.
