Now you may think how can the eyeglasses be a translator and interpreter, but it is true, two people understand each other by the virtue of eye glasses, though they are speaking different languages.
The glasses are designed by NEC, are the perfect international travel companion in that they take a foreign language, interpret it into your own language and then cast the interpretation onto your retina so that you're able to seamlessly speak with others.
There are four features of this device : the glasses, a microphone, a projector and computer. The computer is worn around the waist and serves to translate the language being spoken. The microphone, of course, provides the audio input. The projector displays both the original language and a translation of what was said into the user's native language. It casts them onto the user's retina. Two people using the system would be able to hold a productive conversation without the help of an interpreter.
Supposedly, the retina projection helps one to use the glasses for hours without any eye strain. The projection is on the peripherals of the vision, meaning that one can look directly at the person whom he's speaking with.
Despite the possible problems, such a pair of glasses could be an extremely useful and exciting development. While we're not 100% hopeful, NEC is reportedly trying to get the glasses ready for market by 2010. They'll be aimed primarily at business users.
