Going to the movies can be pretty frustrating if you're hard of hearing. At home you can turn on the closed captioning, but in a public theater you're left trying to read lips. These subtitle glasses solve that problem, by giving you your own personal set of subtitles to read.
The glasses, developed by Sony's UK lab, pick up a signal with the subtitle information that's transmitted inside the theater, and projects the text onto the bottom edge of the glasses. This allows hearing impaired customers to read the captions, without putting subtitles on the screen that can distract other theatergoers.
That's fantastic, but I think it only scratches the surface of what can be done with this technology. For example, it could also be used to provide multi-language subtitle options for viewers who don't speak the film's original language. Or there could be an in-car version, that projects route and GPS instructions that a driver can see without taking their eyes off the road.
Sony says they expect to roll out the system next year in the UK, with other countries to follow later.
