Echolocation and Frusteration

I get really frusterated not knowing how much my daughter can see.

In Touch: News for Blind People did a show on Echolocation recently. Echolocation is using sound to figure out what is around you. For example, if someone holds a board to your left, and you snap in front of you and to your right, it will make a different noise than snapping to your left does. It’s part of mobilaty and orientation training in some programs. I dont know how I feel about it. I guess I think that humans would have a hard time using it. It is was bats use to get around. I dont know. I’d have to see someone use it to really understand how it works.
