We've seen a fair number of gadgets designed to assist the hard of hearing, but they usually involveof one kind or another. (First things first, we suppose.) Few have been dedicated to , much less any form of entertainment.
That's why an invention by scientists at the University Carlos III of Mardrid caught our attention. It's a technology that projects subtitles onto eyeglass lenses in real time for deaf moviegoers. And as Pocket-lint points out, it could also find a broader market because they could be used by hearing people who want to view films in a foreign land. (Theaters could issue them the way they do 3D glasses, for example, except as an expensive rental.)
Perhaps next they'll invent a way to overlay subtitles on a movie projected.
