Open Source GIS and accessing various special needs populations.

[Sampson, David]

Alright folks,

Do you have your thinking caps on?

I'm looking for examples applications, companies and organizations using
open source GIS to help enable special need populations.

For example, a GIS/GPS guided walking cane for the visually impaired.

Web mapping applications to connect special needs populations to
services.

Devices that allow these populations to gather and digest GIS info, like
Braille readers / interpreters

Just interested in what the open source world is working on.

Cheers
