Signing Web Pages

I’ve been hearing about avatars and the latest does sign language. This avatar compares nothing to the ones we see in forums, pictures of favorite people, shows, things, and whatnot. Sites and applications adapting human avatars have them walking in front of the Web content you’re viewing much like a tour guide.
It sounds like the sign language avatars work in a similar vein based on reading the news report. Great concept and wonderful for those who know sign language, British sign language in this csae. However, I think captions work better since it reaches a wider audience than just sign language.
