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.
what roni, you have some brain reader device or what? I can't even file a coppyright sue on u. *smile * this is exactly what I was suggesting. 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.
Yes that's right and I have worked on voice based web systems before and they work very well for blind people. The device can have a keypad in braille format where
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.
Yes exactly. that is what my interface idea was.
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.
Well the data can be kept on a central server and the railings can just have dumterminals. and as far as the braille key pad goes, we can have even compac idea like the one used in mobile phones. because the use of braille is slowly getting reducedamongst blind people. regards. Krishnakant.
