One day you may be able to wear glasses that translate other languages in real-time and display them onto the glasses’ lenses so you can read it, if NEC is successful.
Called a retinal imaging display, the glasses incorporate a microphone and displays language as expressions. Surprisingly, NEC plans to have a product out in 2010, although it’ll probably be prohibitively expensive for the general public.
I wonder though about how efficient this would be in a crowded room? We tend to underestimate how powerful our brains are at doing things like filtering noise and speech, even in a crowded room.
