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

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.
