[Blindtlk] Echo Location as a Mobility Aid, World Access For The Blind?

I've got to voice a little skepticism here also.  I can certainly 
tell if someone's looking at me if we're in close proximity and 
having a conversation; and occasionally I'll be able to hear 
someone's body between me and another object (a feature of 
echolocation.) But without other clues, I don't think I (or most 
blind people I know) can purely tell if someone is looking at us.

Ray:

I'd say, with all due respect, that your explanation below is an 
explanation
looking for a phenomenon.  Do we *really* know that we can tell 
when
someone's looking at us? Has there been a double-blind study (in 
the
medicinal trial sense) wherein participants also were 
blind-folded with at
least ten thousand participants so that the statistical 
observations have at
least a small chance of being valid? I doubt it.  And can blind 
persons
*really* tell when someone's looking at them from across a room 
with lots of
intervening sound and people? I rather doubt it.  I think what we 
*think* is
being able to tell is merely observing the body and other 
reactions of those
whom we perceive to be looking at us.

This is your terminal skeptic speaking here.! (grin)

Mike

Here's another thought.  I wish someone would come up with a good
explanation for this.  We all know it's true.  You know how you 
can feel
someone's eyes on you-and therefore-you know they're watching you 
and when
they're not?  It's something we all know is a fact:  and yet, 
nobody seems
to have bothered to try to work out just exactly what is actually 
going on.
Is it the eyes of the watcher that  cause this?  Could it 
possibly be the
way in which a person's seeing eyes reflect off what they're f:  
sort of
like radar so that what we feel is actually the way light bends 
or bounces
back off us?  I sort of have a notion that's what's going on.  
When a
sighted person looks at you, their eyes put out a kind of what 
you might
call light detection thingy:  maybe the retina and the way it 
causes focus
has something to do with this:  And, this causes the light around 
the person
being looked at to bend in to the shape of that person, I guess 
maybe that's
what makes the shadow.  Anyhow
 , the now bent light bounces back to the seer's eyes and that is 
how they
can see us.  The byproduct of that focused light reflection is 
felt by us in
the way that the light refraction around us changes.  Well, 
anyhow, that's
my notion:  And, it seems to me that if somebody really worked 
out how this
actually happens, might we not   develop ways in which this 
finaminan could
be useful?  and, after all, who better to learn how to take 
advantage of and
learn to use it them the blind ourselves.

 I'm saying and it is available through the national library 
service.

 Hi all

 I have read some material on this online and wondered if people 
could give
 me:

 1.  Information on this organization?
 2.  Have you done this training? Was it effective? If so, how?
 Especially interested in the views of adults.
 3.  Practicalities, costs etc.

 I really would appreciate your views or if you yourself don't 
know
 suggestions what other lists I could ask this on.
 Thanks
