Vuzix is probably best known for its not-exactly-fashion-forward personal video glasses, which enable a user to take in video content from something like an iPod or PC using LCD screens mounted in a pair of glasses: the result is like the equivalent of watching a screen more than 60-inches across, and it’s private: even the person in the airplane seat next to you can’t tell you’re indulging your yen for ancient episodes of The Beverly Hillbillies. At this year’s Game Developer’s Conference, Vuzix introduced products it thinks will take its personal video products to the next level: the CamAR and PhasAR accessories add “augmented reality” capabilities to the company’s iWear AV920.
