In traveling as a totally blind individual, using echo feedback is my
biggest source of information! Like ah, check it out -- with a cane in your
hand, you can reach out -- what, 5, 6, 7, 8, feet? And with your hearing, by
use of picking up and interpreting echo feedback from obstacles 360 degrees
around you , the distance then is like 10, 20, 50, 70 90, 100, 200, 300,
Plus feet. Boy, the few times that I have lost the tip from my cane --
woo -- I lost my major echo factor and it cut down my information to mostly
touch only; granted, natural environmental sounds were still there, and
there was still some super limited echo feedback from my footsteps. And in
contrast, comparing operating with the echo feedback created by a good metal
tip, to going without, it really made me feel like I was traveling --
blind.
And for any of you who are thinking of how to improve your travel and are a
cane user, and if you now do not use a metal tip, do try one. It sends out
the best type of sound for echoing back -- it carries out the furthest and
"paints" the object the clearest. (Paints, is I guess a word that I have
seen used by the military in terms of how a radar beam will cover the size
and shape of a distant object.)
In writing all this, it is my opinion, though it is also the experience of a
big bunch of other blind travelers, too. And I will also say, that all blind
people are different and what works for one, is not necessarily the best for
the next person.
