i believe this device will going to replace the cane one day. i might be only the blind, who still can not use cane perfectly. so i'm hunting any such assistive device which can serve the purpose specially for walking. so one thing i would like to suggest is that please try to develop in that way, that blind person can also walk in hill area. hill area contains lots of obstacles around the way. and i'm positively going to purchase this device as soon as possible. thanks.
