However, I myst say that i have seen assistants helping what appeared to be a younger blind person learn to use these patterned tiles a few times. Not really sure how it works better than a white cane, but in theory its a nice idea.yu888http://www.blogger.com/profile/18394699273966555952noreply@blogger.com
