Sign language in virtual worlds


Hursley, UK: Imagine sitting through a lecture and seeing a digital
character projected on a screen behind the speaker, interpreting the speech
in real-time, in sign language.

An IBM avatar translates the spoken word 'good' into the corresponding sign
in sign language. The new technology allows a person giving a presentation
to have a digital character projected behind, signing what they are saying
IBM Corp researchers in Hursley, England have developed virtual reality
'avatars' that can translate spoken words into sign language.

The technology is meant for use in the real world, and could be useful when
interpreters for the deaf are unavailable, or when a conversation is

"This technology has the potential to make life easier for the deaf
community by providing automatic signing for television broadcasts, and
making radio news and talk shows available to a new audience over the
Internet," said Dr Andy Stanford-Clark, Master Inventor, IBM Hursley. 

The system, known as SiSi (Say It Sign It), works by using speech
recognition to convert a conversation into text. From there, SiSi translates
the text into the gestures used in sign language and animates a customisable
avatar that carries them out.

The IBM team and advocates for the deaf caution that the system is still a
prototype. It also works only with British Sign Language for now.

However, the system is expected to move out of the labs and into commercial
products soon.
