Epson Moverio
Google Glass may be getting all the attention — both good and bad — over the last few years, but it isn't the only smart glasses game in town. Epson is already on its second generation set of smart glasses. The Moverio BT-200 boasts two projectors, which are touted to offer a more "immersive viewing experience" than Google's one. The BT-200 is also smaller and lighter than Epson's first model, the BT-100.
