They had the old Sonic glasses that did that, Scott. That was 70's
technology.
The glasses were heavy, and you had to wear a separate control module.
I'm
sure now that could be made considerably smaller what with better
integrated
circuits and denser construction, as well as better battery technoligy
than
NiCads. The glasses had three transducers arranged in a triangular
pattern;
with the bottom one being the transmitter, and the two upper ones canted
slightly outward to give you a stereoscopic view of your surroundings.

I wish you could mount that on glasses! Have them either vibrate or beep
in
your ear. Leave the hands out of it!

Question: how can you operate a cane/dog, gps/bn, and mini guide all at
the same time? I had a hard enough time with just the cane and mini
guide,
but I was amazed when I had an opportunity to use the mini guide (a
device
like it anyway). I avoided countless collisions with people in a very
crowded school that my cane would not have picked up because of how
short
I have to hold the cane in those crowds. I have just not had the money
to
get a mini guide, plus I have found my cane to be quite sufficient...
until I run into something (figuratively and literally) where I realize
that one of those magic Milky Way bars (as another poster put it) would
have been quite handy.
Also, for those interested, the device sends out an ultrasonic beam from
one of the two front ports. The other port senses the reflection of
that
beam and sends the strength of the reflection to a processor which tells
the vibrating motor how fast to go (in my case it used pulses; the
closer
together the pulses were, the closer the object).
Have a great day,
Alex

Subject: [gps-talkusers] The mini guide
This is what I use as well. The GPS can only be as accurate as
is
humanly possible and it will not help you find anything that
specifically. The mini guide has saved me many times trying to
find
poles, benches etc.
It's thankfully not too expensive. www.senderogroup.com
Good luck!
