Well, if the system is a bit interactive, some more things can be done
to assist the blind person. I am compiling a document which I will
post soon. and if the hand held device can do a little bit more at
the control of the user then lot of things can be done.
As a balance between low cost and maintainence as JTD suggests and
interactivity as desired, we could have the same repeater system giving
out not just plain speech but interactive speech, like a tiny voice
enabled web page. When the user is in close proximity to the railing
transmitter, it dumps an entire website into the user's device. This
website will be based on the particular railing position. The user then
interacts with it asking it for detailed addresses and locations around
it, as desired. The device can have a keypad in braille format where the
user punches queries and the device reads out the answer. Once the user
moves on to another railing, the old data is replaced by a new web site.
The advantages of this system will be that the railing will have to be
fed once with the respective web pages and after that its sealed against
dust and water and maintainence is not needed. The user gains by getting
to ask customised queries.

Rony.
