Students at IBM in Ireland working on a project called Accessibility In Virtual Worlds, are working on way to make 3D worlds and gaming accessible to blind.

Quote from the BBC:

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.

Virtual worlds open up to blind.
