[games_access] Virtual worlds open up to blind

Hey this sounds like some competition for my research ;-)
(....which can only be good).

I can assume they will be using IBM's own "secondlife". I heard
there's lots of blind people working at IBM actually.

Two things I didn't really understand:

"There is also sound attached - for example, if there's a tree nearby
you will hear a rustling of leaves," said Mr O'Brien. So in Secondlife
objects can have sound embedded. and a Tree with rustling leaves
usually will make sounds already in SL so that's not something blind
people miss out on.

The work also developed tools which uses text to speech software that
reads out any chat from fellow avatars in the virtual world that
appears in a text box. Secondlife already has voice over IP which
works pretty well actually.

Cheers Eelke
