A Computer Display in Ordinary Sunglasses? 182

Posted by Cliff from the bet-you've-been-waiting-for-these dept.
DonaldP asks: "I've been making head-mounted displays for wearable computers for a couple or three years now; I think my latest and greatest 3rd Generation display is a big step ahead! It fits inside a normal-looking pair of sunglasses. Why would I do something like this? As far as I know, this is one of the only ones available out there - the only others that come close are made by MicroOptical Corporation, but it's been years and you STILL can't actually BUY any of their products. With large companies like Xybernaut holding plenty of patents on wearable computers and going strong, is there a place for my little one-man company? Any tips for making it on my own? Or is my best hope to hook up with a giant?" I've been waiting for a nice and portable HMD for years, and this has the advantage of not making you look like a Borg reject (although some of you might like that look). HMDs still have a way to go to be practical for everyday use (many still require perfect vision or contacts because they are clumsy with glasses) but I'm sure these drawbacks will be fixed with time.

    Start small. Make a few of 'em by hand, make sure they all work, and sell them on EBay. Create a nice business oriented web site and link to it in your EBay listings. Research traditional marketing priciples and apply them. A catchy domain name helps, too.

    This is something you could start now for very little $$. Trying to find someone to manufacture these things en masse would be a pain in the ass and likely require a huge investment. I say, make them all by hand for a couple of years until you are so flooded with orders that you just can't keep up. Then take it to the next step.

      That's good advice, unless you find it turns to a nightmare of technical support, repairs, warranty, and eyesight-loss/seizure-related lawsuits that become too much to handle yourself. Then you'll have take it to the next level. ;-) Okay, maybe that's a bit cynical. It sounds like you're onto something good with your device, so I guess what I'm saying is don't let a good idea starve or die because you didn't pay attention to boring/annoying (but important) details that you could have farmed out to someone else (even if that means spending money, giving away equity, revenue sharing, whatever).

        Sounds like you have the start of a working model. The point about eyesight problems is an important one. I used to work (as a softie) making scanners. The optics guys there had been demonstrated simmilar devices. These had been carefully measured to proove that the image was focused on your retina when your eye was relaxed. Properly set up it sounds like these devices will be a lot better for your eyes. Improperly set up and I expect you'll be screwed. Could the device detect if it had become inappropriately calibrated? What happens if I sit on it at the beech, drop it in my beer, then put them on backwards (I know its called evolution, but imagine a reasonable accident!)
        I doubt that you could market this on your own. I'd expect you'd need some technical help, you do all the mechanics, optics and software by yourself! wow! but are all these areas up to the required standard for sale? Maybe you could find some partners or contract some good people. Sorry to have to use a dirty word but you will need some "marketing" to! Can't believe you'd want to spend the time necessary doing this.
        Are there independant testing labs for the safety of optical devices? (I think there are but have no details.) If this was established and I could see your device working, send me the bill.


    • You should also try and figure out a way to get your page posted someplace where it'll be seen by about a quarter-million geeks who've been dreaming of something like this for at least ten years.

      Seriously, at $1500 a pop, limited to 320x240 greyscale, and with a 2-month waiting list [aeinnovations.com] (and that was presumably before today), I'd guess that you're not quite at the point where every single one of us will buy one, but even so, you probably did just secure at least a few orders. (It'd be interesting if you'd post back in a few days with the results.) The sweet spot would probably be if you could hit 640x480 and at least 8-bit color without going too far over $600.

      Still, this is already pretty nice -- I'd call myself "tempted", but not quite "seriously tempted", as it is; definitely interested enough to keep an eye on your progress. The price point is probably more important than the features: I'd be more likely to buy it as it is if you got the price down than at the current price if you got the features up.

      Good luck.

    • IBM have had a wearable prototype for years - I think I first saw it back in 1998.
      The first version was a stripped out thinkpad 560, running at between 100-200Mhz (cant remember exactly - my memory is failing with advancing age), using an IBM microdrive for storage (and to reduce size.) I think it had a 320x240 monochrome screen.
      I remember they had souped this up to an 800x600 colour screen in a later version.

      The unit didnt have a keyboard - just a trackpoint mouse mounted on your finger to be operated by your thumb, and a kind of 'trigger' mouse button, along with a mic for voice commands.
      If I remember correctly, it was envisioned for engineer types to look up plans and diagrams whilst working on the machinery. eg. a jet engine technician could call up a schematic and have it superimposed on the actual parts of the engine as he was working on it.

      How about this:

      A pair of display glasses kept next to the copy machine. When it jams in location D2, the user puts them on and an animation of how to remove the jam is superimposed on the actual mechanism. The same applies to any kind of mechanical task (think fixing an automobile, or the advanced chapters of the Kama Sutra).

      Or this:

      A firefigter eners a burning building; it's smoky and nothing can be seen. Radar maps the suroundings and shows a wireframe model on his heads up display. (Actually, I think they have things already which can see through smoke, but perhaps they could be made lighter). Or maybe containers of hazardous materials would have a transponder that would alert the firefighter to its presence, display a red dot at its location, and show its material safety data sheet on request.

      Or this:

      A headset that gives a surgeon a heads up view of her patient's vital signs, displays plans she has made for complex operations, and integrates with advance sensors to give her the equivalent of x-ray vision.

      Or this:

      A pair of glasses that would allow people identifying rare plants or insects to compare specimens to the taxonomic databases. They could even be integrated with a video microscope so the user doesn't have to bend of a stereo microscope all day.

      Personally, I'd like to get rid of computer monitors. They're an ergonomic disaster, and scaling them up in size creates all kinds of space and energy problems. But I could probably think of a hundred other applications for them in every day life. I believe computer enhanced reality has a huge potential.

        Yes, it is called a Thermal Imager [yahoo.com]. I think the hardest part of this would not the technology, but the application. We see heat in excess of 1000 degrees F, which would quicky melt most any sunglasses.

        However, and this may be a thought to the originator. When we enter a hazardous condition (read: fire, HazMat), we are wearing our SCBAs. These include a mask that connects to our air tank. If there was a way that you could integrate the display onto those masks, with an on/off button, there would probably be a gigantic market for it.

    While the covert HMD is a really neat spiffy product, the bariers to entry into the hardware market are quite high. In order to compete you'll need to be able to finance production operations (the easy part) and incur substancial legal expenses to insure that none of the many wearable computing patents - mentioned as being held by large players in this market - apply to your hardware, and in the event that some can ce construed to apply, you'll need to handle licensing which will probably be at great expense as well. Furthermore, although the SSSCA will probably not add requirements to your hardware but given the current legislative enviroment, similar legislation that would apply, might appear at any moment. As we all know - the wearable computer maker has not reached mass aceptance yet so without sufficient customer base for the computing hardware, the market for the display hardware - normally some percentage of the market for the compute platform - will be extremely small, regardless of how cool the hardware is. For these reasons I'd recommend considering licensing your hardware to a larger player in the market. While you won't derive nearly as much revenue as if you marketed the product yourself, the revenue you collect will be predictable and will be recieved within a timeframe (and I'm making an assumption about Anubis Enterprises) acceptable for small businesses to maintain solvency.

      It is not caused by "eye strain", but by a specific mutation in the rhodopsin gene.

    Something I have considered for quite awhile (Back in '94!) is how to get around in virtual worlds. The solution I came up with is by no means 'true VR', but instead aims to be natural. The idea is that you have a platform a couple inches thick by about 8 feet square. (The size could change depending on what is most comfortable for the majority of people.) The platform would then be divided up like this:

    <code>

    ________
    |\ /|
    | \___/ |
    | | | |
    | |___| |
    | / \ |
    |/_____\|

    </code>

    The user would normally stand on the center square. Each of the divisions ahead, behind, to the left, and to the right represents a direction that the user may wish to go. While in the virtual world, all the user has to do to move forward, is to take a single step forward onto the division in front of him. Similarly the division behind him would cause him to back up. The left and right would strafe.

    The left and right could potentially be a 'turn' as it is in most FPS, but I fealt that the turning should rather be handled by the HMD (say via a Boom Tracker) due to the fact that side stepping is a more natural result to taking a step left and moving your head is a more natural 'turn' motion.

    Anyway, that was my idea and since I don't have the time to build it, I'm sharing it with everyone here. A tip on building tho. It would probably be easiest to take a cheapo gamepad and strip it out for its interface. That way the electronics and software will be compatible with existing and future programs.

    If anyone builds one of these things, I'd love to hear about it. Shoot me a mail at: jNOSPAMbanes@techie.com

    Just remove the NOSPAM.
    • Maybe you're looking for something like the NES Powerpad [hypermart.net] ?

      Or any of the dance-pads available for the PSX?
      • I never know that NES made a pad similar to the design I laid out. I'd always known about the 'twister' style pad, but all that had was a 'sprint race' game and an arobics game. Of course the NES hardware was always way ahead of its software with the Power Glove being the crowning example. (I still have the RS232 interface I built for that thing.)

        I've seen the dance pads in the arcades and I assume that those are similar to the PSX ones. The problem with the 'plunger' design is that you have to make sure you hit the target. When you are in a VR world, you would have trouble with such a design, whereas actual platforms would provide both a large target and feedback by dropping a little (either a 1/2 inch drop or a satifying click like on a mouse).
    • I've seen something like you described advertised on german TV. It was an add-on for Playstation games (and will probably be available for other consoles).

      It consisted basically of the platform you described (it came in form of a "mat" with sensors, so it could be easily rolled together for storage). It also had the different field for going standing still/going forward/backing up/left/right. Additional to that were two poles standing upright on the front part of the mat. These poles sported some IR sensors.

      The purpose of this thingamajig (retailing for about 200Marks, which comes down to $90) was adding reality to "beat-em-up" games like Mortal Combat. Using the map fields you could go forwards and backwards. The IR sensors on the poles would detect your fist/arm "punching". Also it could distinguish between arm and leg usage (probably by using a dedicated sensor circuit for each foot). Also high and low kicks could be done, and a slight jump (with you just leaving the floor for some inches) onto the fore/aft pads would trigger a jump in the game.

      I am sure this thing is available in the US as well.
    • Why not something that works like a 3d treadmill? indiviual platforms that can raise/lower/move (collectively when necessary) to match your movements.

    • Not my idea, but I have never seen an implementation of it, so I wrote a how-to a long while back on building it:

  • This looks great for a nice wearable SSH2 session, but the bulk of my time (and that of the majority of people using computers, I'd think) is spent digging around the web or using tools of fairly high resolution demands in Win2k (3D Studio MAX, Photoshop, MSDEV, etc.).

    If you manage to get it to 1600x1200x32x85hz and retain the general physical characteristics of current models, I'll pay as much as/kill whomever you wish for one. Using an RSI 'cast' to gauntlet-mount a Half Keyboard on one hand and a 4D mouse on the other in combination with one of those tiny stripped down Celery 700 boxes, I'm pretty much set.

      Ummm...would you like the moon with that too?

      Respectfully, this is WAY beyond what the state of the art can support right now, or in the foreseeable future.

      It's a chicken-and-egg problem...the masses won't be interested in wearables until they are more or less equivalent to desktops. But until the masses are interested, the major players won't devote major funding to getting wearables up to desktop level. Which means that only hobbyists and small businesses will do it. Which means that progress will be very slow.

      On the other hand, I think you may be overestimating what you really need. Instead of thinking "What do I need from a wearable in order to do the things that I do on my desktop?" try thinking "What can I do on my wearable that I can't do on my desktop?"

      Here are some suggestions:

      * have a combined MP3 player/watch/note taker/scheduler/data bank/voice-over-IP cell phone/email/pager, all in one go-anywhere device

      * have a personal electronic assistant that helps you remember things based on your current surroundings and other cues (check out the Remembrance Agents Page [mit.edu] for more details)

      * broadcast video of what you're seeing back to your home basestation. If you get mugged, you have a video of the guy's face. If you see a beautiful sunset, you can watch it (admittedly on a small screen) with your sweetie later.

      * mapping software that updates in realtime, showing you where you are and providing you detailed instructions on how to get to your destination.

      * ...use your imagination

      • yeah and what happens when the government starts realizing that they can record everything that you see, and hackers start to grab in and record what you're seeing too? Dunno if I like the implications of that, especially in wake of recent events.
  • Do you want the video camera put in the 4th gen so you can pick up eye signals to control the computer? Blink twice rapidly to close window...
  • A good market for this could be security. Combine a HMD with some form of wearable PDA or 'small' laptop (It doesn't need to be anything high tech, a secure strap/backpack), set it up with wireless networking and you could beam images from security cameras to the users sunglasses/goggles. A 'button', 'pad' or custom trackball style device could be used to navigate between cameras. This would be a niche market admittedly, but I'm sure various uses could be thought of for such a device.. Open for thoughts..

    The picture for wearable fans is getting steadily better. Consider an Ipaq with wireless package, pcmcia video card, IBM 1Gb Microdrive, a Twiddler2, and one of these HMDs. The specs to hook up a Twiddler2 are already out there. You run linux from here [wearables.org] and you're all set.

    Well, maybe you might want another battery :)

    Sure it has a redundant screen. I used to hate that idea. But now I realize that it just means I can still use the machine in situations where the wearable is not appropriate (like the beach) or when I've already taken it off.

    Every year these little handhelds get more powerful and the peripheral market around them gets richer. I think this is the critical mass that will finally allow the normal (non-EE) person to put together usable and powerful wearables. The HMD is really the missing link.

    Just as an aside, I wrote the author about modifying my own M1 to his first-gen sunglasses hack some time ago, and he refused to do the job (for money, I mean) because he felt that his current design required too much "tuning" for each person's ergos. I guess he's licked that problem, and it's nice to know that some people really aren't just in it for the money. He's a good guy.

    How about if you could figure a way to work this with a PDA? The resolution and lack of color would seem to work well with a Palm OS guy. You'd have to work on the interface a bit, but it'd be relatively cool to have your address book handy right where you could see it. You could scribble notes to yourself while walking down the street and what not. HMD+PDA+Expedia = easy navigation, or a quick car crash. (You get my point, though.) Combine your HMD with the black and white Clie's with the jog dial, and you may be able to sell some. Especially to those tech-crazy Japanese.

  • The main problem with a computer display in
    glasses is as discussed above eye strain.


    Imagine an standard but small LCD display in
    front of your eye. To focus on it, is the same
    as focusing on any object 2 cm away from you
    eye, downright impossible unless your extremely
    short sighted. This is easy to fix you put a
    lens in front of the LCD so that to correctly everything
    is focused at infinity or maybe 20 feet away,
    i.e. your
    eye has to focus as if the image was at infinity or 20 feet. But this is still is not good enough.


    The eye (and brain) is built to be continously
    focusing on different objects at different depths,
    and keeping it locked at in single focal depth for
    very long produces eye strain. Worse still is that
    if your viewing a 3d image, the parallex clues the brain gets to what distance an object is
    at, have nothing to with what depth the eye has
    to focus at, and this could cause further problems
    with eye strain, that you wouldn't normally get
    just by staring somewhere for a long period of time.


    True when you look around a room you don't tend to
    notice objects coming in and out of focus, but this is
    in fact because the Brain uses the eye
    to update the model of your surroundings and it
    is this model you normally perceive.

    Until someone can design a system that has
    different virtual objects at different focal depths, eye strain will painfully prevent such
    displays becoming popular consumer items.

How many teachers let you wear sunglasses into your exams? And sunglases with a wierd looking attachment on the side and wires running out of it?

      I think that you're looking at 10+ years until this type of technology is even close to real use, and all it would require is for all glasses to be briefly checked as you head into the exam room.

      And besides, if you want to check it's not very hard to. There are many many ways to get away with cheating pretty cleanly, but then again you're only cheating yourself in the long run.
