I concur with Mr. Andrews's observations re electronic travel aids. Good
cane travel training (especially with canes of sufficient length to be
useful) seems in rather short supply overseas. Were it widely available
I think people wouldn't bother with electronic aids as presently envisioned.
I agree that we may someday see some useful electronic aids (a
nonmagnetic compass?) but that time is not yet.
One problem I see with *all* such aids to date is that they seek to
provide information a sighted person thinks might be useful to a blind
person. I am unaware of any aids that were designed to meet the needs of
the blind whose design was to the specifications of the blind (the "Viper"
might be an exception).
