Where Are Your Contact Lens Displays?

destinyland writes "'We already see a future in which the humble contact lens becomes a real platform, like the iPhone is today,' argues researcher Babak Parvis, 'with lots of developers contributing their ideas and inventions.' He provides an update on the contact lens with transparent circuitry that's being developed at the University of Washington. (Its components will eventually include hundreds of LEDs which form images in front of the eye such as charts and photographs). They've already developed a lens-with-LED prototype that's powered by 330 microwatts of wireless radio-frequency power, and believe the lenses could also be used as biosensors to deliver body chemistry readings (including blood sugar levels). But 'What we've done so far barely hints at what will soon be possible with this technology,' says Dr. Parviz."

      If the population grows, the flying car has to happen one day, because the roads just get too congested otherwise. I see pictures of India's streets today and shudder when even 25% can and do own cars. China is already experiencing those problems. It's either that, or a real mass transit system like the Germans have, coupled with a revolutionary short distance personal transportation device, something that the Segway was rumored to be, but just wasn't. A bike would do, though a bit slow, a scooter like the original honda cub isn't bad either, but neither fold up enough to take on most busses, trains. It would also take an attitude adjustment on people's parts. The flying car just isn't reality because neither aerodynamic nor lift principles would be satisfactory for the human limitation involved, and anti-gravity would work, if such a thing existed. I would also suggest computer controlled road cars, but I'm not sure if the liability is worth it, if it's only suitable for highways, because, really, people are overall stupid drivers and technology (phones) is only making it worse so far.

      DNF is just a game and technically feasible, they just were directionless and unhappy with everything they made. Hurd was superceded by Linux, so it's like complaining that an effective gas lamp was never invented when the lightbulb is already here.

      Cold Fusion may be a pipe dream... but I hope they accompany these computer lenses with eyeglass counterparts. I don't like contacts, personally. I can see it happen, but I'd figure the computer power to get anything done would have to be miniaturized so much it'll be at least another 20 years... or that they have a terminal/server configuration where the lens/eyeglass acts as only a display wirelessly connected to a real computer elsewhere, be it on the person himself somewhere or on the internet.

      > If the population grows, the flying car has to happen one day, because the roads just get too congested otherwise.

      I'm not sure that's exactly the right solution, actually. (Mainly, I'm thinking that congestion in 3D is even more complex and dangerous than congestion in our current 1.5D. Both are easy when you're the only one on/in the road/sky, but there are more variables to manage in the sky crowd than on the road crowd). Flying cars are also impractical for energy reasons; if we're already using too much energy on cars and afraid that greater car ownership will make this worse, then *flying* car ownership will take this to new levels of energy extravagance. If we want to take to the air, we'd need to do it with something more like a flying bus that takes relative large loads of people between a relatively small number of stations. Then we have a crack at energy efficiency gains, space efficiency gains, and keeping the number of vehicles aloft (and the complexity of their routes) simple enough to be manageable.

      But yes, we have a scaling problem as population density increases. We build on areas (scaling quadratically, then), and then as we start building up and down we're building in volumes (scaling kinda cubically). But roads area linear. People flow in toward the center, or need to go through the center, and it jams. The current solution is to try to channel people into highways that go around, to minimize time spent in the center, but that is a bandaid and requires everyone to use a lot more foresight in picking their route - and since it makes the trip longer, it's only enforced by negative feedback (try the middle first, only go around if it's already jammed... but by then it's too late, isn't it?). I think our mid-term solutions (until we can build a reliable flying bus) lie in implementations of some older ideas:

      1) multi-level roads. Yeah, it's kind of the 1950s' vision of the future. In practical use, we already have elevated light rail, buried subways, and some new highway interchange hubs are stacked like 6 levels high. In a city, you'd probably want a stack like that at the center to manage the through-highways, and you'd want the ground-level roads to have a lot of clearance and width, because you'd want all the heavy vehicles to use the ground routes. Then you'd want the next tier(s) up to be for light city vehicles... private people commuting around in something like electric Smart cars and 4-6 passenger variants. The high tiers would be narrower and slower-traveling, of course, but less congested because all the delivery trucks and buses and dump trucks are below. You'd also be able to do different parking garage designs since you'd have multiple floors with road access.

      Mostly, the extra tiers will only be in the densest city core, so that road area scales up more closely with population/traffic density. But the idea is that it'll work out better for both people living in the city and for people coming and going.

      2) skyways for pedestrian travel. Some city cores also have already partly implemented this, such that a few big malls and hotels and convention centers and stadiums are all linked up and you can walk between them without getting rained/snowed on or hit by crazed taxi cabbies. It's equally effective to have these a few floors above ground or below ground, and it's also possible to have a few high traffic areas be powered conveyor belt type walkways like those we've already seen connecting airport terminals. Your routine can then be drive in ONCE, park ONCE, walk/conveyer around through your errands, get back in car and drive home ONCE. As opposed to the present day juggling act of cruise around for parking, park, do task, cruise more, park again, do task, and so on. Vastly less road use needed if implemented cleanly. It requires people to walk more, but we know from our European brethren that walking won't kill you, and IMO more Americans would walk if there was a clean, dry, non-dangerous route available, especially if it meant we could avoid a stressf

    Can anyone shed some light on how the optics of a contact-lens display would work? After all, when all is said and done, this is going to be a display that is not simply "close" to your eye, but ON TOP of it, and I don't know about others, but my eyes are unable to focus on anything closer than 5 cm (2") or so.

    There are mirror/lens systems in VR-helmets and those fancy spectacle-like, wearable displays that create a virtual display some distance away from the viewer, but I don't see how that could be replicated in a contact lens.

  34. How do you focus? by imkonen · · Score: 2, Interesting
    Doesn't a contact lens sit closer to a human eye than anyone could ever actually focus their eyes on? In fact doesn't it sit on the focusing element? I guess the retina is different from the lens, but they are not very far apart IIRC, and can probably be considered one optic. IANAO (O = opthamologist) as you can tell, but I know a thing or two about optics. You cannot just display an image (either by absorption of the backlight or emission from tiny LEDS) onto an imaging lens (human or mechanical) that looks like what you want to display the way you can with a HUD or a computer monitor. What you percieve as spatially separated regions in your view map to different angles of incidence of light rays impinging on your lens. Each "pixel" in your eye (or literal pixel in a camera) collects light passing through all regions of the lens, but only at one angle. So to create a 256x256 display on a contact image that appeared in focus, the lens would have to emit light over a controllable grid of 256x256 angles.

    I don't know that the technology is theoretically impossible, but I think articles like this usually gloss over this not at all minor technical difficulty. Transparent circuitry is much easier because of this same phenomenon. If you cover up 50% of the area of a contact lens with completely opaque circuitry, you won't see the circuits in your vision, you'll just see a reduced intensity as if you were wearing sunglasses, because the circuitry will be so out of focus it will appear uniform. If your circuitry is only covering 10% of the area, you probably won't even notice the difference.

    Thank you. I've been wondering when someone would figure this out.

    You can't scratch a letter onto the surface of a 35mm lens and expect that letter to show up on the film. It doesn't. It's in the wrong part of the light path.

    You couldn't paint a letter onto the front of an eyeball and expect it to form an image on the retina. It won't. It's in the wrong part of the light path.

    You could probably blink a red LED or a green one or a yellow one, and that might be useful. If your contact lens could _project_ light onto the retina, or out onto a surface, sure it would work. But it's near impossible to _project_ a focused, sharp image out of a structure less than a tenth of a mm thick.

    None of the articles I've read have ever addressed this point.

  42. Where are the decent Head Mounted Displays? by MrSteveSD · · Score: 2, Interesting

    Let's take a step back from the idea of contact lens displays to the lower-tech idea of wearable Head Mounted Displays. Where are they? It's been 20 or more years since the promise of Virtual Reality and yet I still can't go into the average computer store and by some VR goggles. You can buy them on-line of course but frankly they are awful. Most of them have low resolution and a field of view equivalent to a 14 inch monitor on your desk (cunningly advertised as being equivalent to 70 inch screen at 10 feet).

    Field of view is really the most important thing for an immersive experience, not the 3D aspect. Imagine the impressive view you would get looking out from the top of a mountain. There is no useful 3D information in the scene since everything is too far away, but it certainly wouldn't feel fake despite the lack of 3D. If you look at the same mountain view through a tiny window though, suddenly you are now longer "there", and it just becomes a picture of a mountain view. That's the dire experience you get from today's narrow field of view. Even the super expensive HMDs that cost as much as a house do not provide a normal human field of view.

    I think the problem is that there is no real drive to bring virtual reality to the consumer market. Companies are far too comfortable making games designed to be played on a low field of view window on the world that never moves. If one of the major console makers pushed the idea of VR, it might change things. I won't hold my breath though. I've been waiting 20 years for VR and there is just no will there to go with the idea despite all the technical advances we have made.
