[Blindtlk] Electronic mobility aids

[Gary Wunder]

Hi, Alyssa. I am interested as you are in what may come that will detect
objects too high for the cane to find. I do not yet see them in production,
and even the things we are asked to evaluate don't seem worth what it will
cost to buy them or maintain them. They all seem very expensive and fragile.
I hope your problems with your dog don't require you to get another one and
have to handle the emotional separation. 

Warmly,

Gary Wunder
