While the details are somewhat vague, Project Glass by Google became viral once out of the starting gate. Since it started yesterday, over 4 million people already viewed the video with few thousand more each hour. So what is it? In part, it is a testament to the popularity of Google+, the search engine giant’s answer to the ever growing Facebook. But Google Project Glass is also a glimpse into the not so distant future, where augmented reality and wearable communication device/computer are daily staples. In fact, the technology behind the concept are already in use. For example, the classified Target Acquisition and Designation Sights, Pilot Night Vision System (TADS/PNVS) found on the Boeing AH-64 Apache attack helicopter gave its pilots all around situation awareness. Google’s Project Glass does the same except luckily you won’t be pointing a chain gun or missile with it.
