[AI] Virtual worlds open up to blind

I do not think we are missing out much by not having access to these virtual 
worlds. It is a good occupation only for people with plenty of time on their 
hands.

Online virtual worlds could soon be accessible to blind people thanks to 
research by students at IBM in Ireland.

Some estimates predict that 80% of active internet users will be using a 
virtual world in four years' time.

The company said that it is keen to ensure that blind people are not 
excluded from an environment that sighted people will take for granted.

The students have designed an audio equivalent of the virtual world using 3D 
sound to create a sense of space.

They were working as part of the company's Extreme Blue research initiative 
which brings groups of students together for 12 weeks to solve problem set 
by
senior researchers.

The project - called Accessibility In Virtual Worlds - is what the company 
describes as "a proof of concept" at this stage, but it will be passed on to
IBM's Human Ability and Accessibility Centre in Texas for further 
development.

For their work the Irish team decided to use the Active Worlds online 
environment rather than the more popular Second Life (which has almost 9.5m 
accounts)
because it allowed them more flexibility.

Active Worlds is a collection of user-made virtual worlds that people can 
visit via a web browser plug-in. Like many other virtual spaces they let 
people
make many of the artefacts, including buildings, found in them.

Audible cues

The research team exploited this ability to tinker with objects in the 
online world to make it more hospitable to the blind.

"When the user comes into the world, the items are described as well as 
their positions," explained Colm O'Brien, one of the team of four 
researchers who
worked on the project.

"There is also sound attached - for example, if there's a tree nearby you 
will hear a rustling of leaves," said Mr O'Brien.

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.

Characters in the virtual world can have a "sonar" attached to them so that 
the user gets audible cues to alert them to when they are approaching, from
which direction and how near they are.

A number of blind mentors have given advice and feedback to the team - one 
in IBM's Dublin lab and two based at IBM's research centre in Texas.

The students have also liaised with the National Council for the Blind of 
Ireland on their work.

As well as proving that the idea is feasible, the team has made a number of 
recommendations about accessibility standards for virtual worlds which 
should
help the developers of the future.

"IBM believes that virtual worlds are going to be the next big evolution of 
the web and if this happens...it's not right for blind people to be missing
out on what the rest of us have available," said Mr O'Brien
