Sorry if this topic is old, only just now checked email.
One quick point: I want one of these AMD babies! I've been saying forever
that they should make something that looks like two canes with crossbars,
and now here they are.

Subject: Re: [Blind-rollers] an idea
I use my white guide cane and electric mobility when out and about in
public. It helps a great deal in new places and I was trained with a
mobility
specialist hired by the OVR Blind and Visual Services in Texas. I have
been very successful with it and avoided many accidents and rough bumps
because it also defines change of terrain and obstacles before I get to
them. I
use the right hand for joystick and left hand for the swaying of the guide
stick in a 45% sweep continually. My cane has a roller tip on it.

All:
While an interesting idea, an AMD offers little real likelyhood that
its user will be as independent as the user of a white cane (in all
its varieties) I think there is litterally no one who if enough time
is spent in training could not use a long white cane. The only
exception might be people who use crutches or walkers, however those
same people could be just as independent if they used a chair and a
cane (I use mostly a manual chair with my cane and while traveling can
be slow going especially on inclines it can be done.)
The AMD also does not have the near universal identification that the
white cane has in the public mind, (I say near universal because
people basically walk right into me everyday lol) The only practical
use I might see is for getting around a nursing home or other
institution-like closed environment.
Just my two cents, from experience, not through any formal training in
the subject matter.
My Best,
Paul
