LCD Screen Double-channel Stereo Video Glasses

As TV's grow ever larger, viewers sit farther and farther back from the screen for the more theatrical experience.

But there is a concurrent trend in consumer electronics to shrink the screen and bring it closer to the viewer within inches of the eyeball itself. Video Glasses, which is worn like glasses, uses two small liquid-crystal displays to give the wearer a feeling of looking at a large-screen TV from about seven feet away.

Video glasses didn't take off in the 1990s, when it was introduced. Consumers probably remember them as looking like the helmets used to train astronauts and with four-digit price tags.

But the new user-friendly versions continue to get lighter, cheaper and more portable, although they still look as if they come from outer space. Also known as personal media viewers, video glasses or head-mounted devices the category is new enough that no one can agree on a name these gadgets generally cost $200 to $400. They weigh 2 to 10 ounces, come with their own headphones and plug into portable video devices like iPods, DVD players, video game consoles, video cameras and even some cell phones.

You generally can't see what is going around you. But then, the people around you can't see what you're watching, so the Video Glasses is useful on planes or elsewhere where privacy is an issue. Most of the tiny screens have a resolution of 320 pixels by 240 pixels, but models are coming out with twice that resolution. Some of those screens can give the illusion of watching a 50-inch TV from about seven feet away. The devices are popular with gamers because they offer an immersion experience.

The weight of video glasses is becoming less of a problem as manufacturers find ways to shrink the electronics and use lighter materials. You'll be able to enjoy private showings of your favorite movies wherever you happen to be - whether you're travelling, sitting in the park or on those long commutes.
