Would You Wear Video Glasses? 239

Roland Piquepaille writes "According to EE Times, an Israeli company has developed a personal video display device that looks like a simple pair of glasses. You can use these glasses with various sources, such as a portable media player or your cell phone. This technology promises to eliminate the dizziness phenomenon usually associated with this kind of display. And with these glasses weighing only about 40 grams, you'll feel that you're viewing a 40-inch screen from a distance of 7 feet." Video screens embedded into eyewear isn't that new, but the footprint of these is smaller than what I've seen before, making them cooler to wear on the subway.

    Certainly never on a subway or any other public place where you should be alert to your surroundings. They'd be ideal for taking on a trip to use on a plane or in a hotel room.

    I remember seeing glasses video displays this small a decade ago. Of course the problem with them then, and even now, was resolution: The resolution was so terrible that it has limited uses, seriously degrading even the already low quality of television.
    • I agree, resolution is key. Though I would be willing to put up with 800x600 (I'd use a larger virtual desktop) if they managed to solve the other problems like size/weight, wireless connectivity and high cost.
    • Resolution is Somebody Else's Problem - the glasses just provide the optics to project the display to both of your eyes. So they're not a finished product, and need to have Somebody Else provide the display, and therefore the resolution will depend on Somebody Else. (Among other things, this means don't hold your breath for a shipping date.)

    I worry about the long term effects on the eyes. You are constantly focusing on sonething only an inch or less from your eye, and the eye strain might have a negative effect over time. Remembering Steve Martin's movie 'The Jerk' where a device designed to keep your glasses from slipping down your nose eventually made everyone on the planet cross-eyed, I would use this but definitely limit my time.

      The projection onto the lens will be at a focal length that is much longer than an inch. So just because you are looking at something an inch away, you're not focusing at an inch. Very much like if you get close to a mirror, and look at the objects that are behind you in the mirror. The image is a few inches away, but the objects are that few inches away plus the distance between the mirror and the objects. It's perfectly safe.
      • Not to be a physics nazi, but the 'image' is not at the surface of the mirror, it's actually a virtual image that lies behind the mirror. The correct way to say it would be "the surface is a few inches away, but the image is a few inches away plus the distance between the mirror and the objects".

        Don't feel bad - when I was an undergrad I walked out on a physics recitation because the TA fucked up the difference between real and virtual images too, and I was so disgusted I left ;)
      • "It's perfectly safe."

        On the "as bad as television" sense of safe. But not worse.

  • I might buy it (in both senses of the word) as soon as I've experienced a working prototype making all these promises come true right before my very eyes.

    From the TFA these glasses are being touted as a portable multimedia experience. With the (lack of) details on the websites it appears that wearing then will significantly fill out the users field of vision (which you would hope for in order to get the best viewing). So we have:

    1) Expensie tech (As in a couple of hundred)
    2) Not physically large
    3) Highly visible to everyone else that you are using it
    4) Blocks out significant part of your own visual field (and also audio)
    5) Designed to be used outside of your own home (as otherwise why use it)

    In a private situation (or on a plane) these glasses would be OK, but wear them on the subway, or sit in the park and you might as well put up a banner that says "Mug me!!"

    But a solution would be to put a web cam on top of the glasses, and feed it back into the system as a "picture in picture" so you can keep track of the outside world while you gasp at the unblelievable plot quality of m:i:III :D

    This is clearly a step forward and will lower the cost of wearable screens, we can just hope it's not as much vaporware as it sounds. I also have some issues with the whole wearable screen tech business: Every "videoglasses" producer has always promised 40" TV, for as long as these have been sold, but usually the let down is quality. You know a laptop 12" screen can also seem to be 40" as long as you have it close enough, and a laptop screen has better resolution.

    I've used the Sony version that you plugged into a TV, and that version was very low res, about 400px in height. I'm not sure you can make "affordable" wearable displays with any good resolution. Even though Mirage, the makers of this device, are using a single OLED/LCD it still going to cost a lot to produce enough pixels to satisfy the eye.

    And I can't figure out how my glasses are going to fit in there.
    • Yeah.

      I saw a couple manufacturers of video glasses at CES. One set wouldn't fit over my glasses at all. The other set was supposed to fit, but didn't. I seem to have a head on the larger end of the spectrum, but still.

      And the kicker... IIRC both devices had QVGA resolution. Rather useless for hacking, and not really that good for TV anymore either.

And yeah, that would be expensive, but surely not nearly as expensive as a 50 inch physical display using LCD, plasma, OLED, or whatever."

We are talking about a linear measurement, which is a proportionate difference. Twice the distance appears to be half the size.

    40 inches is about 1 meter. 7 feet is just above 2 meters.
    It does not talk about resolution. I have 2 x 1600x1200 20", so 40" would be 4 times as large. However when I stand 7 feet away, it looks about 4 times smaller, making it standard.
