Basically, Google plans to be selling special eyeglasses by the end of the year that show information, entertainment, and ads. They also might be able to connect to social networking sites, and more!
Read the article, it is very interesting.
I do not know why, but I always found the concept or idea of virtual reality to be extremely exciting. What Google is expecting for these glasses are amazing! For example: If you see a person you feel like you have met before, facial recognition could identify them! (if such software becomes accurate enough.)
