Hi friends, Great that someone from India has developed this handy device and that's why it is so cheep. At the first read, I think that it can be a very good supplement with cane. Since cane helps us in not just detecting the hurdles or puddles but it also helps us in many other ways. For example, with cane one measures the width of a muddy area or an open drain as well as the hight of the foot path or other alivation and moves accordingly. The stick gives us a confident gait also. No doubt that it has some limitations which technocrets are now trying to overcome but a gadget like this is going to replace it totally is a bit of exaggeration. But congrats to my engineer friend from Chandigarh for developing this handy device. Naresh
