New Device Could Overcome Low Vision 65

Posted by timothy from the gibsonian-artifacts dept.
Johan Jonasson cites a story at Wired which reads in part: "Low vision can't be corrected with medical procedures, glasses or contact lenses. But a new product from Microvision that uses lasers to 'paint' rows of pixels directly onto the eye is helping people with low-vision see clearly again." "The device, called Nomad, consists of two pieces: a small control module worn clipped on to a belt, and the head-worn display. The control module receives a video signal from a computer -- a desktop, laptop or a wearable computer -- which processes this signal to drive a low-power laser. The light is then scanned by a small mirror to create images." Essentially, it's the same type of display that many wearables come with, but with the image enhanced to compensate for the low-vision user's greater needs.

  • it mentions that it works by providing light intensity 15X that of a standard wearable display unit. Wouldn't there be a problem with persistance of vision, just like when you look at a light source or anything else brighter than ambient light?

    I'm not trying to condemn the technology or anything. I think its great that there's the potential that people who normally couldn't have their vision corrected will see an improvement. I'd like to see a more in depth article though, this one is not any better than an infomercial.

  • Wow, I was just reading a book about this called The Visionary Position (great
    book, talks about the history of Virtual Reality). I haven't finished it, but
    this Nomad device was originally called the VRD (Virtual Retina Display, I
    believe). The concept was that of Tom Furness, the "father" of virtual
    reality. He created the first VR helmet back in the 60s by accident while
    working on a new design for cockpits. Tom and the HIT lab were working on the
    VRD and was licensing it to Microvision, whom they hoped would someday end up
    producing them themselves.

    A visitor to the lab once put on one of the first versions of the VRD. This
    person had one blind eye, and was able to see the images from the VRD in that
    eye. They brought the VRD to a person who was fully blind and that person,
    after locating the point of light, was also able to see the images. They
    determined that this would only work for a very small amount of cases, and that
    most blind people would not benefit from this device.

    Now, I don't mean to damage Microvision's reputation in any way, but at my
    current point in the book, the entire HIT lab is very concerned about their
    relationship with Microvision. They thought it would never end up producing or
    selling a unit. So as you can see, this is very interesting to me :)

    Does anybody have any information about whether or not the HIT lab is still
    working with Microvision on these things?
  • I smell troll. "Natural" evolution takes a l_o_n_g time to chance much of anything and then only in the direction of being better baby makers and providers for same. In case you haven't noticed that is not the area that human beings need improvement in. We happen to have evolved enough to have brains powerful enough (hopefully) to take over where natural evolution left off. From this time forward we are in charge of our own evolution. There is no reason whatsoever to belittle or assume the "evolutionary" inferiority of people with simple handicaps. There is actually some evidence that various types of problem can more often come with high intelligence using normal "natural" evolution.

    Our continued development and growth is now highly tied to improved intelligence. Yet natural evolution does not change the basics of a working system but adds to it. But our brain cases cannot get larger without seriously injuring future mothers. And human females show no sign of changing to accomodate larger-headed babies. The only way we will get higher intelligence on a large scale is through "articial" augmentation and to a lesser degree through improved nurturing and training for greater intelligence.

    Or would you prefer the race remain as stupid and increasingly unable to keep up with current needs as it is now?
  • Just a thought from those of us who have a master criminal mind (Not that I use it, no really) Anyways, I would be worried about a laser image being focuseed on the retina of my eye. If someone could tamper with the display device to increase the laser output, very bad things could happen. Hmmmm. . . Permanently burn "You are a looser" into Bill Gates' eye. This may have a use after all. D
  • With such a device, the genetics of it wouldn't matter. Like a bionic eye basically... Bionic hands/ears/whatever don't require genetic make-up... neither would this.
  • our focus should be on genetic therapy and propogation.

    I sincerely hope you're Troll. I really, really hope so. On second thought, genetic weeding sounds like a reasonable plan. Why not put all inferior beings in a gas chamber? Oh wait, that's been done before. And trust me, a "perfect human" is a contradiction in itself.

    Every scientist has to realize the power that comes from being able to start fresh instead of fix something that is already broken.

    Two words buddy: nuclear weapons. Hit a few buttons and we can start all over again.
  • More likely the next stage of evolution will be us using our technological expertise to repair or augment ourselves. In effect we'd be taking up the roll of creator and god in the various myths that serve as religion. Evolution at its heart is just the alteration of a species over time due to environmental change.

    For the first time in history we are arguably the largest impact on our own environment. We control the quality of the air we breathe, the water we drink and the climate we live in through our own choices. Eventually we'll be able to control it in a more meaningful manner, or we'll die.

    Technology will also allow us to change whats in our genetic makeup; to essentially hit the backspace key over genetic defects that once would've been chalked up to fate, karma or god's will.

    It's not for everybody, but the era we live in now isn't for everybody. There are cultures in the U.S. that choose not to take part in technology beyond the horse and carriage.

    Nope, not a troll, although some people with mod points really don't deserve them. Anyways, to respond to your statement... You are taking my argument and blowing it way out of proportion to how science fundamentally works. Natural selection is at work around us whether we realize it or not, what I am suggesting is that if we wanted to become "uber-humans" in any fathomable timespan, we would have to resort to purely genetics instead of bionics. Having someone born with a specific trait is preferable to adding it via mechanical means. This is not to insinuate that we need to do away with the "inferiors" either. We have our place in the homeless camps (vague reference to Gatacca). I also agree that science should not get too proud of itself either, lest one of our perfect subjects snaps and turns into the perfect psychopath.


    Two words buddy: nuclear weapons. Hit a few buttons and we can start all over again.

    You completely missed my point (yes, i see the sarcasm indeed). What I was trying to get across was that when a scientist is working on a project, it is poor judgment for him to use a dirty test-tube for his tests.

  • Well, given that my deck outside right now measures at 256 times brighter than my computer screen, it's probably not a problem. The human eye is adaptable to a huge range of brightnesses. I believe most retinal damage is caused by actual heating (if you focus on a a really bright, small object) or UV light. With retinal scan technology, I'd mostly worry about the scanning apparatus failing.

    It would be great to be able to use a device such as this to get a more productive use out of that eye. I rely on my right eye almost entirely for everyday use, as the vision in that is fine, but suppose I could use a wearable with display to the other...

    Call me cynical, but if you have one of these things attached to a belt-worn PC (just wait until Bluetooth achieves ubiquity), then you're just asking for trouble. You walk down the street, and suddenly you're in the middle of a game of quake. It'd be a fascinating reason in court for going postal.

Just some glasses (not that thick either) and a nice little chip in your eye. you do need an optic nerve though.
  • Sounds like this device may actually work. And for thoes who don't understand the difference between this and other head mounted displays...

    This one actually shoots light into your eyes, being as you are having a hard time seeing already (ie there is not enought light bouncing off of objects already for you.) this can add an increased amount of light focused directly into your eye. You have to wonder if this is going to destroy your eyes that much faster?

    An example, a hearing aid works like a little amplifier sitting in or hanging on your ear increasing sound levels for the wearer. A stereo has similar function, but simply broadcasts sound for a room.

    Conventional displays from Blue Tooth etc, allow your eye to function as normal and view the reflected light from the display (not targeted at anything in particular.)

    My grandfather has macular degeneration, a form of "low vision". Unfortunately as it's not a problem with focussing, it's not fixed with eyeglasses. It's not fixed surgically either, since it involves the retina directly. Truth is, he had normal eyesight through his seventies and early eighties. Now he can barely read and will likely be blind in a short time. I know he can see much better in very high light situations, which makes sense since the problem is related to the retina not having enough "gain" and so needing excessive amounts of lignt. I suppose this device helps by brightening the world a lot. I bet if a normal-vision person looked through the nomad, it woudl be really bright. A ./ toy? Probably not... these things are usually old-age related and we're really young, right? ;-)
  • Wow, this really looks neat. I was born with low vision that has been corrected to "acceptable" levels, for small values of acceptable. The thing that stinks is that I can see well enough to drive and perform every routine human function, but I'm *just this side* of normal when it comes to detailed work (like computer stuff; ever see anyone with a 21" monitor at 800x600? :) You will when you come into my workplace after I've been reeading the monitor at 1024x768 for a few hours.)

    That said, I know people with much lower vision. For them, life *really* sucks. They see blurred shapes, degrees of light, things like that. This product is a definite plus for them. Even video-camera quality images are much better than what they can get from their natural equipment. For someone like me, it probably isn't really an option, but the fact that we can now restore decent vision to those worse off than I am is great.
  • Somehow I don't see my 80 year old grandmother who is legally blind jumping at this - she still has problems with my father keeping track of her check book on the computer. Given that many of the people with low vision are older and don't realy want all this technology around them I am not convinced that they would ask for something like this.

    I'm not aware of (m)any wearable computers that use retinal scan display technology, but I'm willing to be enlightenend. There's a fundamental difference between retinal scan (no picture plane other than the retina) and LCD goggles, which create an intermediary picture plane that your eye has to focus on. The potential for miniaturization is much greater in retinal scan.
