"Although this interface for the blind is a GUI and can
be used by sighted people, the virtual world space is not rendered
pictorially. Instead, all information flowing to the user is
text-based in order to allow compliance with ordinary
screen-reading technology. Recorded verbal descriptions are also
played for the user.
"Currently, the application interfaces only with the Second Life
platform; however, as a long-term goal, it might be possible to
make this user interface portable to more than one virtual world
implementation. If successful, that portability would enable blind
users to learn only one client application that is specifically
tailored for their needs rather than learning a separate new
application for each virtual world.
"How does it work?
"The user interface is a Web application, a thin client running
locally in the Firefox browser that communicates with Second Life
through an agent on our server. The application is implemented
Toolkit widgets to provide a virtual world user interface that is
entirely keyboard-navigable and screen reader-friendly. Nothing is
permanently installed on the user's computer""
