Is it that it looks for a wall too far away? Or did you just point a sensor down and have it reach in front of the walker and if it got to be more than like three inches or something? Anyway, I'm really impressed. I was about to cry when I saw that. Even though its only one person, thats one person. YOu can't put a price on it. This truly shows how FIRST can affect us and help each other out. I just wish more of the world knew.
