well regarding the bus issue, it is right that on narrow streets it will be a problem. but may be we will have to think over and try to get some solution out (that is what research is all about) *smile*. and the fm system is perfectly wonderful as long as it can tell me what is the current area/ colony and which is the near by railway station or even bus stops. you see, different bus stops have different names and we tend to identify areas many a times on the names of their bus stops. Ruia is one such example. and the major thing about the issue related to identifying the bus is that some times there are more than 1 busses standing one behind the other. that time for a sited person it is easy to know which buss is coming in one glance. so it is equally important for a blind person to know which busses are currently at the stop. may be the other way around this problem of narrow streats is that give the signel from a distance close enough for the blind person to make a judgement and far enough for him to get the right enterval. again this is what research is all about. the bottom line behind my research at IIT was "it is very easy to find out the how part of it, what needs to be done is to find out the what part of it". given technological developments today, with some patient findings there is nothing impossible. I am currently doing a project for a talking book reader and its cost was going up drastically, the boards were costing a lot but some patient and determined market survey helped me to get small embedded boards for a very very cheep rate whith even better solution for my project. sorry to be a bit off topic but the point here is to sort out what we need to do first. how wil that be done can be sorted out later. regards.
