substitute for seeing eye dog

I could see some benefit for this device but it is no substitute for companionship

perhaps but it is certainly a very good tool. Not everyone can have a seeing eye dog... either because of costs or allergies or living conditions.

lots of blind people have plenty of companionship other than a dog. what this cane has in common with a guide dog is that it extends "vision" beyond the tip of the cane; gives an indication of what is 2 or 3 steps ahead, rather than just one.

BTW - i had a blind friend in college, amazing guy. he knew campus so well that he would carry his cane just so others would realize he was blind - he did not actually use it. he was also majoring in math/science secondary education, with a 4.0 gpa, and was in the ohio state university marching band.

I knew a blind girl that did gymnastics. Flips 'n all. Scared the living crap out of me when I saw her do that. Its amazing what a person can do. Truly amazing.
