[rehab] vibrating NFB cane

[Dick Davis]

If it is what I think it is, it was demonstrated in Dallas in 2006.  It was
an NFB cane that had a sonar unit attached.  I tried it along with a number
of others.  It was heavier, and it did not appear to provide much in the way
of new information. 

There was another unit that hung around a person's neck and looked somewhat
like a camera.  We tested it here and weren't all that impressed by it.  I
know it was sent out for beta testing by the Science and Technology
Division, but I don't think they ever went into production.  I cannot
remember if the modified cane was one of their projects, but I bet their
president could tell you.  Contact information for them should be on
NFB.org.  

There was also a Japanese company that created a small, relatively
inexpensive handheld unit that I hoped could detect stopped and moving cars
so deafblind people could know when it was safe to cross the street.  We
tested it here, and it couldn't.  I believe they were marketing it at the
2006 NFB convention.  

Sonar and related devices have been around since at least the 1970's, and
none of them have caught on.  They seem to be limited in a number of ways:
distance, ability to focus, lack of detail, inability to detect drop offs,
etc.  The good old long white cane still provides a lot more in the way of
information and does it much cheaper.  

Hope all this helps.

Yeah, this was a 50-50 cane that a guy in Baltimore invented.  *I heard
we were selling it for $200 but can't find it on the website.  It is
cool, has lots of possibilities for people who are deaf blind.

It seemed that the vibrating thing was something you put around your
neck. 
You then used a regular cane with it for those obstacles on the ground. 
That's what we had at research and development, but there may have been 
other things in other places.
