If u have guide railings and the user walks up to that point all problems are resolved. U have location, orientation and distance. The beacon can transmit proper info at the additional cost of having several rails and beacons -eg 7 at prabhadevi signal. Also now they cannot be used at a distance.
well once such a system is implemented they will certainly walk over to the railling.
The guide railings are meant to differentiate between road and foot path safety limits and have the additional facility of instructions emobssed on them. The guide rail does not bring the user to his destination, it only guides till the footpath ends and the user has to now decide which direction he needs to take for what destination. This choice will be fed to him by the electronic system. Once the choice is made, he crosses the road and moves on to the next railing. All information may be difficult to punch into a railing and the user will have to feel a very long way to read everything.
Agreed and then this will need a little bit of analysis as to what can be actually fed.
A simple alternative option of providing user orientation to the signpost can be to incorporate buttons in the railings that the user
Keep in mind however that we are talking about an additional asset to be fitted to the roads. how long can the raillings can go? will there be objection from public? > This will provide
accurate information about the user without using heavy technology.
that is the major point. we are not yet really got converted from Mumbai to shanghai. so what you say is right and I believe let's work on what ever resources we can use.
The problem here is that how does the post identify the device to which it has to broadcast? There can be a system of temporarily docking the user's unit into the railing port with optical proximity like a bar code reader. So while the rails act as sensors, the signpost is only one common transmitter connected to a common computer.
perfect. I think this was what you were telling me on the phone.
So here is a practical example.
A user is slowly walking along the road from Sah and Sanghi auto shop towards Prabhadevi Junction, feeling his way on a railing. As he approaches the Century Bazar signal, the railing tells him that a junction is approaching. Just before the junction, the user momentarily docks his device into the railing port and removes it. The radio signpost then tells him about his bearings and what directions he can take to what destination. The user wants to go to Ceat house which is a few buildings away from Century Bazar. So the post instructs him to take the immediate left signal, cross the road and take the next railing to his right. As the user feels his way ahead, he reaches Ceat Building. The building names of popular buildings could be embossed into the railing.
well again, how long can be the railing? we can't have it from one end of Mumbai to Other, may be I did not get your idea so it is my humble request to clearify. my personal view is to have the blind person be notified that he is around a certain area etc. and if the railings are at proper prominent locations, it will be perfect.
