Google's Project Glass recently got a new blast of publicity for its augmented reality specs with the video "How It Feels," which purportedly shows what it's like to be wearing Google Glass. The project also held an #ifIHadGlass competition, in which applicants were invited to submit what they would do if they were given Google Glass. The competition's winners, yet to be announced, are eligible to receive some of the first copies of Glass, provided they're willing to cough up $1500.

But projecting information on a transparent medium and putting it at eye level isn't new technology; it's been around for a while, and it's called a heads-up display. And given that it's been around for a while, it's no surprise that Google isn't the only company making waves with heads-up technology. Other companies have projects ranging from Glass imitators, to spy gadgets for police, to specialized contact lenses. Check out this gallery for some of the coolest non-Google innovations in the world of heads-up.

  • Vuzix M100 Smart Glasses

    <a href="">This Google Glass competitor</a>, recently tested at the Consumer Electronics Show, can be tethered to Android devices to provide a heads-up display of what's happening on your phone.

  • Epson Moverio BT-100

    The <a href="">Moverio BT-100</a> acts as an at-home entertainment system embedded in a pair of wraparound glasses, letting you watch TV, view videos in 3D, and surf the Internet. The glasses are controlled by something that looks suspiciously like a TV remote, bringing to life the idea of "<a href="">a movie theater screen right in front of your eyes</a>." Still, compared to Vuzix or Google Glass, the <a href="">Moverio's</a> features are limited. Price: <a href="">$699.99</a> Available: <a href="">Now</a>

  • Many, Many High-End Cars

    Heads-up displays are relatively old news in the car business; luxury cars like the <a href="">2012 BMW 3</a> and the <a href="">2013 Cadillac ATS</a> now have them as a matter of course. These displays aren't as exciting as the kind found in Google Glass; they won't let you text your friends or join a Google hangout. But <a href="">they will</a> help you navigate the roads, tell you to brake if you're about to crash, help you save fuel, alert you if you're going over the speed limit, and more.
