Nintendo and a Japanese company, NTT, are working together to make this a reality. The project they are working on will make it possible for deaf students to keep up with a lecture in the classroom. The project "captures instructor speech, converts it to text, and saves it to the cloud while also sending it to devices -- like the DSi." (Joystiq) It's hoped this project will not only help deaf students but also students with learning disabilities and other challenges. I could even see it helping the reading ability of students.
I can just see it now, a teacher asking their students to make sure they all have their game systems ready before beginning a lecture. I know I'd love it if I was a kid!
