Google gave people a clearer picture of its secret initiative called Project Glass – the company’s first venture into wearable computing. Of course, the glasses are not yet for sale, but that’s not to say you might not encounter employees of Google stepping outside with them to test out their capabilities or to do their best Star Trek impression. The prototype version Google showed off on Wednesday looked like a very polished and well-designed pair of wrap-around glasses with a clear display that sits above the eye. The glasses can stream information to the lenses and allow the wearer to send and receive messages through voice commands. There is also a built-in camera to record video and take pictures. Project Glass is one of many projects currently being built inside the Google X offices, a secretive laboratory near Google’s main Mountain View, California campus where engineers and scientists are also working on robots and space elevators.
