Watching movies has increasingly become accessible to the deaf because of subtitling. It is now a standard feature in DVDs and blurays and even downloadable video content has the option of getting subtitles either as a built in feature or downloading a separate subtitle file. But subtitling is not just within the realm of digital media. There are many theaters now that offer a subtitling service for those who need it.
The current system revolves around the use of a glass screen that is placed in front of the person, the glass then reflects text from a pixel board that is mounted at the back of the theater. This is an effective way of providing subtitles in theaters to those who need it but the difficulty of this solution is that those who want to get subtitles will have to seat themselves in a specific area in the theater to make sure that they get to see the subtitles.
Sony realized the limitation of this problem and has developed a new technology to provide subtitles to people who need them. The prototype are a pair of glasses that a person can wear when watching a #D movie. But the technology here is far different. The glasses allow for the subtitles to be projected on to the glass you are wearing, so this means the viewer can sit anywhere he wants to and still get to see the subtitles. The subs appear like it is part of the screen, which is a cool effect. Sony is still developing the glasses but expect the final product to look slimmer and svelte.
