Google stunned the technology industry this year when it revealed its plans to sell Google Glass, eyeglass frames that put a small computer display in a person’s field of vision. But some less well-known companies have been selling wearable displays for years, with the military as a dedicated customer, and one is now launching a rival product with a similar design. The move could be seen as a validation of Google’s idea, but that still doesn’t mean consumers will warm to such gadgets.

Google’s new competitor is Vuzix, based in Rochester, New York. The company’s product has a less catchy name than Google’s—Vuzix Smart Glasses M100—but it contains a microphone, an earpiece, a camera, and motion and GPS sensors, and it’s powerful enough to run a version of the Android mobile operating system.
