    MicroOptical, a company in Boston, has a pretty good technology: the image from a tiny LCD in the temple of a pair of glasses is sent through one lens from the side and off a tiny mirror embedded in the lens. A VGA display appears two feet from the person wearing the glasses. There is no blocking of the rest of the visual field. I've tried it and it works well, as long as you are OK with wearing glasses. (Ordinary glasses. Like people wear.)

    It looks like these guys are actually well behind the cutting edge. There are several already-announced and soon-to-be announced devices that surpass this quality for significantly less money. Perhaps this is their first pass at a lower cost, larger market production device, but this isn't much to write home about.

    Arkinstad and BiVideo are two competitors that come to mind ... both which at least claim higher specifications at a similar or slightly lower price point. Check out www.afb.org.uk/public/5steps.html. It's quite interesting how these companies got started - one from the medical retina scan buisness, the other from the CCD industry. Neat.
  • nope...they've been talking about these things coming out soon for 10+ years now.

    Your search - Arkinstad - did not match any documents.
    No pages were found containing "arkinstad".

    And this search [google.com] didn't yield any information on direct-to-retina displays.

  • For perhaps a better set of information about safety concerns and the like, go to the academic source of the technology in the first place: UW's HITLab. [washington.edu]

    The retinal display page is here [washington.edu], for starters. I don't imagine that the publicly traded company which got the technology would be as interested in disseminating this kind of info....
    For what it's worth, they actually did quite a few trials of this at the UW's Medical Center, which is actually a very well respected hospital, and felt quite confident in it's safety.

Think about it for a minute and you will see that this will help some people who have to wear thick glasses, but the fact is that this device shines light onto the retina. The eye still has to pick up the light and send it to the brain.

    But back in reality, a bevy of local scientists has discovered that humans can also use lasers to stamp holograms onto the eye.

    In what way are these holograms? Holograms use interference patterns to store information. This seems like simple vector graphics.

    The Nomad's release this year will be the first commercial introduction of the retinal-scanning technology, which does not block the user's vision.

    Yet the prototype from the article does seem to block out most of the wearer's vision. I'd appreciate confirmation or a denial from anyone who has played with one of these units.

    Vast quantities of research still do not magically appear on the web. That does not mean the work has not been done. Your concern for safety is admirable. However, don't let yourself fall prey to the sort of superficial search for facts that one normally associates with TV reporters. It's also grossly unfair to those who are working on this technology.

  • I had the opportunity to view the MicroVision demo unit at the US Display Consortium's investor's event in Manhattan a few months ago. The monochrome unit wasn't bad, but as pointed out, there are better and cheaper microdisplays out there from companies like eMagin's [emagin.com] Organic Light-Emitting Diode (OLED)-based technology and the displays from Zight [zight.com] (formerly Colorado Microdisplay) and Three-Five Systems [threefive.com] which are based on Liquid-Crystal on Silicon (LCoS)technology. The only advantage I see (pun intended) is that you can see through the MicroVision device. It is up to the end user whether that functionality (which will undoubtably be matched in the near future by the other technologies) is worth the considerable expense.
  • Hmmm, but you don't mind a giant vacuum tube pointed at your head, with an electron gun at the back?

    I did the Walmart thing for a year, standing over a nice little laser that helped me find prices for stuff 90% of the time. No ill affects. Control is the key, lasers are really good at emitting a narrow and specific wavelength of light. Keep the power reasonable and these things will be a lot safer than say, oh I don't know, an arcwelder.

    Fear is the Mindkiller.

  • How about "staring at someone using an arcwelder." ? Or staring at any other incredibly bright light source that will definitely make one go blind in a hurry.

    Point is, there are common items that people are exposed to every day that would pose a much greater vision threat than this low power laser device.

    The amount of light is undoubtably far less than even houselight, let alone the sun (remember, your brain measures light on a logarithmic scale - sunlight is exponentially brighter than houselight. This logarithmic measuring is why lights appear to dissapear only with linear attenuation, not quadratic as it actually is.

Also get some brain wave monitors added to the sunglasses' frame and "train" the pair to learn commands like "pan" and "zoom" and "toggle nightvision" and things like that. Soon, you've got people walking around with what looks like a pair of Oaklies when really they've got the ultimate spy vision equipment. They can see things kilometres away, see infrared, nightvision, etc. No need to worry about getting blinded by a light when using nightvision either, as the signal as the emitters could be smart enough not to send anything over given thresholds. Add in some facial recognition software and he's got robocop style target acquisition. You can get mission updates or important info displayed in a cool text box or something, or even a 3D model of the building or complex you are supposed to be breaking into. Run the power to the devices up the strings that let the pair hang around your neck. Add in digital camera storing capabilities and you can be snapping photos of anything without appearing to do anything, since it's just another command that the pair is trained to pick up. Any malfunctions, just simply remove the sunglasses or disconnect the power supply and you've got an ordinary pair of sunglasses again. So yah, it's just a couple of refinements of the techonology away. Who said the movies were wrong; it's just easier to do it in Hollywood than in real life.

However, this device shines a laser through the iris. Is it really designed to follow a moving target? Or are we all going to have learn to keep our eyes still in order to read the display?
  • Flying toasters beamed directly on your retina. Cool.

    Those who stand to benefit from the technology bear the burden of proof in demonstrating its safety, if there is any credible reason to question its safety.

  • BTW, just to clarify what I'm asking for:

    To evaluate the safety of this product, it would be necessary to do double-blind, controlled, peer-reviewed clinical studies which compared a test group who used the product under real-world conditions -- which is to say, several hours a days for weeks or months -- with a control group who did not use the product. The comparison would need to test for eyestrain, visual acuity degradation, and other possible effects on the visual system, as well as potential neurological or psychological effects such as headaches. I haven't seen anything remotely like this.

    There are two studies which could be mistaken for something like this on the site. One is Laser Safety Analysis of a Retinal Scanning Display System [washington.edu]. This does not do any clinical evaluation, though -- it's just a comparison of the power output of the system to established laser safety standards. As I mentioned in my first post, it doesn't deal with issues of prolonged exposure from everyday use or possible effects of raster scanning. It takes standards created for an entirely different laser usage mode and applies them to this new product category. It doesn't do any clinical testing for visual or other problems.

    The other is Decreased Flicker Sensitivity with a Scanned Laser Display [washington.edu], but it's actually not about safety or health effects at all. It just compares one aspect of visual acuity between traditional displays and retinal scanning displays.

    There are also some papers on the safety of laser ophthalmoscopes, but since those aren't used for hours a day for extended periods of time, again it's a whole different usage mode.

    So, it's a big site and it's possible I missed something. If there has been such a clinical trial, I'd appreciate a specific reference. Thanks.

    I couldn't find much in the way of specifics on the web about MicroVision product safety. It appears that the company considers it sufficient to demonstrate that the power output of its lasers is below established safety maximums. However, this does not seem an adequate level of testing for an entirely new product category, which involves by its nature long-term exposure and a unique retinal rastering effect.

    Quarterly Report [yahoo.com] -- "Our products may be subject to future health and safety regulation that could increase our development and production costs. Products incorporating retinal scanning display technology could become subject to new health and safety regulations that would reduce our ability to commercialize the retinal scanning display technology. Compliance with any such new regulations would likely increase our cost to develop and produce products using the retinal scanning display technology and adversely affect our financial results."

    I wish I could report that the company was taking the possible health risks of its product seriously, but that is not the impression that I get from my web search. There is no word on controlled clinical studies of the product's effects on people with normal vision, for example.

Wearable fans have known about the project for a long time, but the devices were only being sold to "system integrators", meaning corporations interested in designing computers to use them. I was going to buy from one of their competitors (who don't use retinal scanning) sometime in the next few months, but now I'll wait.

  • I've seen an earlier version of this. It was a bit bulky, and it looks like the real change in Nomad over other older Microvision products is in the size. Still, it's not exactly like it doesn't occlude your vision. The unit does block your view a bit, kind of like looking through a very strange barrier; that's the only way I can describe it. You also have to line it up correctly, or else I imagine (they didn't turn it on until it was lined up right when I tried it) it must look pretty funky. They aim to make full-color versions, but the limitation there is the blue laser. It seems there isn't a suitably portable blue laser yet.

  • The real problem is that people who have optic nerve degeneration or retinal damage are not going to benefit at all from this invention. Why in the world would people with normal vision want to wear something like this? It seems that this is an invention with no market whatsoever.

  • Just picture it, you go to Starbucks to get your double mocha frap or whatever the hell is there and instead of seeing people sitting around reading books: they're all staring blank at a wall through semi-normal look glasses. Most public places people will be staring off into space and either typing or concentrating on what they're reading. ::grin:: We're all going to look like freaks.

    And just my two cents: I think this looks really cool but I'm with a lot of the other people who posted that they're gunna wait to see what happens to these peoples eyes after a few years. I'm quite fond of my eyes and I'm not going to buy one until I'm sure I'm not gunna end up with a page of my favorite book burned into them. ::grin::

  • Besides, it's FAR MORE acceptable on the international stage to slaughter 100,000 enslaved soldiers who don't wanna be there in the first place than it is to simply assassinate the thug at the top.

    Ehh, I only break a sweat when I'm without online games or pr0n, like I am now because of just moving.

    Anyway, it's amazing, when TV became omnipresent people decried wasting time that would better be spent reading or listening to the radio all night long.

    This is just a brief stop on the way to borgification, so enjoy it while it lasts.

  • Well, let's hope there is a screen saver. Talk about long-term burn-in problems for the clock in the corner of your eye.

  • This is just like the heads up display that Apache (the helicopter, not the webserver) pilots have been using that has a little monocle deal attached to the helmet.

    Well, i think. Anyone else know?

  • I hope that soon, retina scan devices will change authentification as we know today. Users are fools!!! How many type passwords UPPERCASE when there are lowercase?

  • Sounds interesting. If the device operates on the principle on a laser, I bet the laser could be modified to not be affected by the lens of the eye. This could have interesting effects for people with less then perfect vision.

    You could read a digital book without glasses, or see a HUD for your car. Pictures could be taken with a digital camera and super-imposed. Night vision and/or infrared vision without bulky vision gear perhaps?

    The biggest problem would be screen burn in. You remember what happened to those monitors that only shown green. Burned in. Can't let your retina get burned. Also, any kind of a power spike would fry your eye. How about a virus written for these devises communicated via built in cell phone? Not cool.

    I think I will go on the list of people who think this is a good idea, but will wait a couple of years for everyone else to try it first. "I got the first one on the block!".... Hey, more power to you. I will learn from your "beta test."
  • Projected overheads on windshield glass already exist. I suspect they would not be replaced by nomad--perhaps there'd be a plug so the systems could share data.

  • The rapid mouse twitching and jumping in reaction might give it away, tho.
  • Laser beams right into my eyes? But I need those eyes to see! I'm just going to wait until they can implant the monitor directly into my brain.
  • Yes, this is a very cool idea. And if it were cheap ('cause I'm frequently broke) I'd get it. the waiting comment was (obviously) a joke, mostly due to the exponentially greater amount of problems wiring things directly into the brain rather than just wearing the laser display.

    **Requisite cliche** We're one step closer to the wearable computer with this one.

    Being able to see what's on my computer through a device strapped to my head has limited application in my world. What I'm looking for is the computer to see what I see through a device strapped to my head.

    The smartasses among us will be quick to point out that this technology exists and that it's called a camera but I need something smaller than that.

    Photography has always suffered from the need to tote around equipment and, while that equipment has become smaller and smaller, there is always the need to remove it, ready it, and take the shot. I believe that once a camera is developed that is small enough to fit comfortably over the eye, that doesn't impair the users vision, and that can be activated with a minimal amount of effort, we will see a greater number of pictures which right now are just missed opportunities in viewers minds. Art, science, news; everything will benefit from the ability to instantly shutter away a picture for later use. We shouldn't be projecting in, we should be looking out.

    My thought is that a lot of you guys are being a bit harsh. They say it isn't going to cause blindness I am willing to suspend my disbelief for a while. The thing that really caught my attention was that on there somewhere they said that the images projected onto the retina could be seen by some legally blind people. They certainly don't need to worry about it blinding them, and can you imagine a blind guy being able to see with something like that? I mean, it would probably have to sense where everything was with some kind of sonar type thing, and display in wire-frame, but that's better than nothing I say. Hmm, there are some limitations though, would it work inside a car? What kind of range? Anyway, this idea interests me because I have had a friend who was legally blind and I wonder if he could be helped with some kind of "bionic eyes"...
