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

[Mike Freeman]

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.
