Okay.  How do I do that.  I am in school for masters of rehabilitation
counseling.  We probably should talk about this on the student division
list.  Can you send me the link?  If not, I will find it at some point soon.

Justin,
Oh you're in school? What do you study? You should join nabs list if you're
in school.
Glad you have time for fitness amidst school work.
Ashley

Hello, Everyone,

I'm going to point out that there are two Justins involved with this
conversation. There's Justin Williams, who wants to hide his potential
echolocation abilities, and there's me, Justin Louchart, who is an
echolocation teacher and strives to make my skills and the skills of others
public information available to all interested  parties.

Julie, in response to your question about cane taps being used for
echolocation, there are two parts to my answer as an educator and as a
scientist in the field.

First, yes, your cane tap can be used as a relatively bad echolocation
signal.

Second, emphasis on the relatively bad.

The cane tap comes from the ground, hits the target, and reaches the ears.
Meaning that all of your images are going to be bent, blurry, and
inconsistent. Not only that, but furthermore there is no real aim or
directionality in using a cane tap. Next, the cane tap doesn't work on all
or even most surfaces. You cannot modulate the volume or the frequency of
the cane tap in anywhere near the same way you can a tongue click. Finally,
your acuity simply isn't as good with a cane tap, no matter what you do. You
won't be able to see the front versus the back of a car with your cane tap
from fifteen feet away.

It might be worth mentioning that if you're using your cane tap for
echolocation, riding a bicycle independently in unknown environments, riding
a mountain bike on advanced trails, hiking on your own, doing independent
mountain climbing, doing advanced tree climbing, and accomplishing a
thousand other independent recreational activities is much less convenient
or likely to happen.

I have no fear when I travel, no matter what I'm asked to do. Flash sonar
and other perceptual mobility techniques give me the options to do anything
from walk to the grocery store without running into anything to go bicycling
on an unknown street with my students. Flash sonar opened doors for me and
for countless others that most blind folks don't even realize are closed to
them. If you ask most blind people why they don't go mountain biking,
hiking, or why they don't play soccer with sighted peers, they're going to
tell you that they don't even want to. Well, how much of their not wanting
to is a result of their not thinking it's easy or fun? How much of it is
because blindness and people around blindness indicated to them that it's
either impossible, or not worth the effort?


I don't have to worry about any of that. I see my environment quite
similarly to any sighted person, mine just doesn't have color or extremely
fine details. I can choose how to navigate an environment usually a block or
half a block away, depending on clutter. If you have that preparation, a
million things are easier.

Justin
