Google Glass Preview is an app that is going to change the way we look at the world, again. Google Glass is quickly establishing itself as the newest and greatest tech invention to come out in the past few years and Preview is going to help establish that.
The Google Glass Preview app will make virtual reality a very real part of everyday life. The app allows users to look at posters of movies in theaters and see the trailer play for them right before their eyes.
Rather than having to open up one's smartphone and search for each trailer individually on YouTube they can now cycle through films on the go. All users have to do is say "OK Glass, preview the movie" while looking at the poster and the app does the rest.
