  • I wonder if you could make a beowulf out of people-puters.... They're very modular, have a long MTBF, and, well, enjoy the fork()ing process. Of course, killing child processes might be a bit of a problem...



  • It's the same as why WinCE is bad for portables - most OSs don't scale down. They have lots of fat that needs to be trimmed. The modular design of Linux lets you dump what you don't need and come out with a sleek, streamlined kernel.

    Down with monolithic OSs!

  • Have you looked at the pictures on the site? Did you ever wonder why there are so few pictures of people actually wearing these things, and that most of those pictures are tiny?

  • Linux is the optimal OS for stuff like this, as was already mentioned.

    Anyway, this kind of stuff is great. I can envision going to CSE class and being able to try out code as the Prof. talks about it without carrying around a distracting laptop, and so forth. With a remote linkup (somehow in the future) you could check out your email on your wristwatch and so forth.

    Lots of possibilities, and the fact that it runs Linux now is great!

  • I still don't think that any OS available is suitable to run a wearable. There is a need for a new OS to run only for wearables. Linux and WinDoze and others currently avaiable are only suited for a desktop environment. Wearable computing presents many other variables that must be taken into consideration. The fact that it's completely portable, the viewing style, the way information is called up, etc.. --- "I am Jack's smirking revenge" Tyler Durden
  • I suppose that at first this type of stuff wil be ultra geeky, but there will come a point when it is practical for anyone to have this, and then they'll just have some people on MTV say it's cool, have the kids on Dawson's Creek wear them, and then it'll no longer be dorky, huh?

    Really, are you going to let what popular culture says is good to wear prevent you from having neat gadgets?

  • Its good that Linux is moving into new markets. Embracing Linux for wearable computers will allow makers of them to create powerful systems for far less money than, say, a Windows system. Licensing fees are irrelevant in Linux, and the hardware needed to get equivalent performance is much less. With Linux at the center of these devices, perhaps wearable computers will soon be in the price range of normal people? Military applications of a reliable, wearable computer are unreal. Camping uses are amazing too... Add a GPS system and a cell phone, and if you get lost in the woods, a quick email or IM to the local authorities, and your exact location gets through easily. It could work as a smart beacon too, not simply transmitting a signal but information about the situation as well. TO explain the full potential though would take forever. This is a great thing.

  • the BeOS has a pretty good scalability, stability, and is POSIX compliant. Could be another cool alternative to mainstream OSes...

  • Go read Snow Crash by Neal Stephenson.

    It contained bit characters who always had wearables on, usually gathering intel for your favorite three letter agency. They were called gargoyles.
  • Not really off-topic. It's a reference to snow crash, by neal stephenson. Gargoyles are people who have wearable computers, and who constantly collect info/intel from their surroundings. Kinda like the ultimate in wearables.

    The main problem with wearable technology is power. It really defeats the purpose of having a computer that sits in your shirt pocket because you need a kilogram worth of batteries to run the thing for a day.

    This is the reason why most of wearcomp stuff runs on embedded CPUs, such as the Motorola Dragonball series (as used in Palm) or the ARM chips (as used in Psion and Newton), NOT X86. Xybernaut does great stuff, but so far their systems have been hampered by the fact that they insist on running Windows on their wearables, so they need hefty processing power. Not that there are many companies in the wearable business anyway...

    What Linux will offer is the ability to adapt to multiple platforms: you can do your development on your top-of-the-line Athlon system at home, then quite easily port onto your uCsimm [uclinux.org] system. I personally think that we're going to see a lot of new wearable systems based on light-weight embedded systems and uCLinux.

    BTW, for anyone who is interested, go see the International Symposium on Wearable Computing [gatech.edu] home page (you can download most of the presentations from 98 and 99 as PDF (abstracts) and RealVideo). Another good place (though still heavily under construction) is the Wearable.org [wearable.org] page. Did you know, for example, that you can harvest power from your shoes [computer.org] to power a wearable?
  • People love to piss on the WinCE (excuse me, "Windows Powered") parade, but it really is new, efficient, largely cruft-free, and malleable, even if it isn't what Palm uses, or there aren't any Dreamcast games using it yet...

    Just because it came out of MS doesn't mean it sucks. Look at the meeces, the keyboards, Excel 97, Hearts, VB, Age of Empires x, and Windows 2000. =P
  • Linux _IS_ a monolithic kernel. It is also a modular kernel. But so is Win95 (don't know about WinCE).

    The distinction is between Monolithic Kernels and MicroKernels. The difference is that Monolithic kernels handle everyhing needed _inside_ the kernel, while MicroKernels delegate certain parts of the OS (i.e. filesystems, Process Management and advanced scheduling) to some "special" processes.
    See Minix (I've seen it) or Mach.

    Actually some aspects of Linux are more alike to microkernels (flush daemon, update daemon, NFS client...), so I'd put the Linux design somewhere inbetween monolithic and microkernel, closer to the former.

    All this just to tell you that you used the wrong word :-)

    I've been researching my own wearable for a while now, and I see two main problems. The first is that I work in an office - going entirely gargoyle isn't an option. Basically, I need something that is inconspicuous. I can walk around with a box or 3 hooked to my hip... I'm a tech, I already walk around with pounds of hardware strapped to my belt. But covering the face with an eyepiece just isn't going to happen.

    Anyway, that's not the worst problem... between a removable eyepiece and a hidden earphone w/ tts software (I have long hair, easy to hide an earphone), I think I have the unobtrusive bit down.

    The real problem is internet access. To make full use of a wearable computer, it needs to be connected to the network. I should be able to real time monitor my servers, be alerted of email, read slashdot, send email, fix my servers, post to slashdot... all while riding in the car, on the train, in the restauraunt. Cell modems are simply too expensive.

    And the current solutions aren't enough. The Palm network offers "web clipping" - which amounts to them sending you what they want you to see. Telnet? Not a chance. Sprint's wireless web service? It has possibilities, but with the metered usage they currently offer, it's not much better than a cell modem for price.

    Anyway, I doubt anyone has a solution (short of start up your own telco/ISP). However, as near as I can tell, the worst barrier to making the most of mobile computing is the communications barrier.

  • This could be the perfect marketing opportunity for Red Hat. "Red Hat in your red hat." If they could make this thing look a little less obtrusive, people would easily get hooked with the proper ad campaign.

    FAIRFAX, Va., Dec. 14 /PRNewswire/ -- Xybernaut Corporation (Nasdaq: XYBR - news), the leader in wearable computing by virtue of there being so few companies in the field, today announced the occasional availability and initial sales of its Mobile Assistant® IV (MA IV(TM)) running the Linux operating system. Linux has become increasingly popular as a robust operating system and contender for the server, enterprise and Internet

    Edward G. Newman, president and chief executive officer of Xybernaut, commented, ``We are pleased by the addition of these Linux-based systems to our product lineup. Our initial Linux sales to major companies in the automotive, shipping and aerospace industries have been -- oh, who are we kidding. The only big upside to this announcement is that we should get plenty of attention from Slashdot.'' He then added, ``Geez, I hope our servers are up to this. We don't want to end up being poster children for that stupid IBM commercial where the guy's in an AA-like meeting and talks about his web site going down.''

  • The pictures that you will see displayed for these systems are second generation wearable computers.

    I had an opportunity several years ago to work on a first generation wearable computer project at the University of Oregon. You talk about lame! That thing was made from the guts of a notebook PC (I forget what model) stuffed into a heavy duty fishing/hunting vest, with a bulky set of virtual glasses and Dragon Dictate for voice control. Control was problematic, and the darned thing didn't even DO that much, but the department head was happy, which counted for more.

    The point is, it was lame and useless, but it served its purpose of proof of concept! That work, and similiar projects, allowed the second generation of wearable computers to be put together as something halfway useful.

    As for the next generation of wearable computers, I think that you will find that wearing one will no longer mark you as a dork or dweeb. Screen projectors will routinely be fitted into standard eyeglasses (or sunglasses, for those who are "too cool" to be a four eyed nerd). Controls will probably be by voice and or some sort of control glove that will not be too conspicuous. And noone will be able to tell you are wearing a computer unless they look real close.

    As for the advantage of a wearable system over a PDA... Well, a PDA has (at best) a 5" screen. I would imagine that the effective size of a projected screen from a wearable could be as large as desired. Can we say 32" monitor?

  • I'm glad that companies realize that Windows CE is not the answer to PDAs/portable devices. On a relevant topic, about three or four months ago Linux Journal ran a story on embedded systems. It goes to show that with the modularity and portability of Linux, developing a port to the wearable computers is more feasible than anything MS can come up with. A dedicated OS for wearable computers makes sense only for a minute, resurrecting the older mentality that code has to be trashed instead of reused, and developed instead of optimized.

The ultimate memory aid. It would make the "To Do List" on all those palm tops obsolete. Or combined these gizmos with ambiguous computing. Imagine your new in town and you ask you wrist watch what's the best Chinese restaurant in town? It talks to all the other wrist watches in town and see which Chinese restaurant has been do the most business. Then ask it which is the least crowded and it would see how many wrist watches were in each restaurant and report back to you. Really there are so many cool things you could do with machines like these that I could write about it all day.

  • Mandate wearing it? If the government wanted to track us they easily have the technology to do so already. Granted, implementing it and requiring us to carry along the tracking devices would incite a full scale rebellion of the people and wide scale mutiny among the armed forces, but wearable computers are not going to herald in a new era of monitoring. Any potential they have for that is already out there. This is nothing more than a PC that takes up less space.

The keyboard that straps to your arm is useless, the harddrive/cpu runs too hot to wear comforably on your waist, the HMD is crap, extremely uncomfortable. The arm-mounted touchscreen is unreadable in sunny weather. To quote him: "Once you add together the CPU, battery, port expander, headphones, microphone, networking card, and GPS car with antenna, this unit wears on you much more then you wear it."

  • Rodney Geekfreund passed away yesterday when he dodged a virtual missile in the game on his wearable, only to get hit by a non-virtual crosstown bus.

  • If you're looking for affordable internet access for your wearable, you might consider investigating CDPD (Cellular Digital Packet Data)

    CDPD is used in the Palm III's Minstrel, and the new Palm V Omnisky Minstrel [www.omnisky.com] [omnisky.com]). If I recall there are a couple of PCMCIA type II and III cards that support it as well (the Spider comes to mind)

    AT&T has 'unlimited' service for it at around $25/month for the palm $55/month for other devices in many areas (called AT&T Wireless IP Service [attws.com]) and it gives you a 19.2k TCP/IP stack.

    The service is damn near ideal for wearable/pda use, so, I wouldn't go so far as to say there are no options for internet connectivity.

  • Yeah, but it's so easy to recompile that it's for these purposes plenty modular. You can just pull support for all the things you don't need, and do a MUCH smaller build.
  • The real problem is internet access. To make full use of a wearable computer, it needs to be connected to the network. I should be able to real time monitor my servers, be alerted of email, read slashdot, send email, fix my servers, post to slashdot... all while riding in the car, on the train, in the restauraunt. Cell modems are simply too expensive

    Perhaps something like the OmniSky [omnisky.com] service currently available for Palm PDA's would be perfect for this sort of thing if the hardware issue could be worked out. Right now coverage is spotty at best outside of major cities, but it's wireless and has a fairly inexpensive flat-rate plan at $50/month. Also, Bluetooth would be perfect for wireless connectivity while wandering around the office.
  • Your comment is a little short-sighted. Have you seen any embedded devices that run linux, like the car mp3 player at empeg.com? Probably not. Saying linux is only suited for a desktop environment is like saying that internal combustion engines are only suitable for full size cars.
  • The best solution I have seen so far is almost a nonsolution. Basically, a small recharging battery pack internal to the main wearable "box," so that you can swap external battery packs without a problem. The next step is simply to have several battery packs which you strap on according to the current demand... most of us have a "home station," or a backpack, or something that we carry around/can get to throughout the day. If you have 5 x 4 hour battery packs, and you swap them in and out every 3 hours or so, you can dramatically cut down the weight in batteries actually strapped to your person. This allows you to also have a large, daylong battery pack you use in situations where you won't be able to swap battery packs.

    Granted, this is all second hand information - I'm building my wearable now, so I haven't had a chance to really figure out if this is more of a pain than what it's worth.

  • Yes, but a modular one.
  • Xybernaut has, in the past anyhow, fallen into the idea that a wearable computer is any computer that can be strapped onto your body. Take a laptop, hang it on a belt, and add a heads-up display. *poof* Wearable computer.

    What constitutes a wearable computer? Well, for one, I think that anything that makes me lose my balance is pretty well out of the running. ("Yeah, I just hang this here iMac off my hip. I walk a bit funny, but I can play Quake anywhere!") Further, traditional input methods are pretty much as waste of time.

    Obviously, voice-based input is the way that things have to go. I've never had a great deal of luck with that on any of my systems, but I recently used Jupiter, MIT's voice-based weather service. Call (1-888-573-8255) and ask it any question that you want about the weather anywhere in the US. It's really an amazing system.

    Short of that, considering the processing power that's required in order to handle voice adequately, a VR keyboard might be a good first step. A HUD could show you a keyboard, floating in the air. Small devices on the fingers (like little round bandaids, perhaps, on the backs on top knuckle) could track your finger movements so that you could type.

    Audio-based feedback, as we all have probably found, is helpful. So now we need a small device on the back of the ear(s), too.

    Glasses, headphone, fingerpads, microphone, CPU. With all of these things, you truly do *wear* your computer. Quite an assembly to get all of this on.

    Is it possible to improve on this setup? Of course. Somewhere in the middle ground between hanging a Toshiba Satellite on your belt and pulling on a computer-suit is going to be the everyman's wearable computer. And if I knew what that would be, I'd be a very rich man. :)

  • I still have great problems with speech recognition and the wearable. True, speech makes the wearable hundreds of times easier to use.

    But.

    What about privacy? Having to speak to your computer while anywhere other than your private office negates all the advantages of the wearable.

    One poster above mentions that he should be able to configure/control his servers using his wearable while on a bus or in a restaurant. A truely useful capability. But what if the guy sitting behind you is ease dropping on your configurations while you speak them?

    What about peoplewho whould use it to manage their investments? Or to handle business deals? Voice activated wearables will never make it in the business world unless they have physical access methods that are as easy to use as voice recognition or the good ole' keyboard.

    Time to sic the industrial designers on the problem.

    And if I remember correctly, you've been able to get linux as the OS for a while now. It's just this is the first press release. Maybe their meaning of "support" is technical support as opposed to just having the OS capable of running on the box.

  • I never said it was 'only' suited for a desktop environment. Don't put words in my mouth. Linux was designed for desktops and servers originally, not wearables. It could run Linux but like AC said, It needs a completely new interface. Could there be an OS better suited for wearables? It's possible, if that OS was designed for that purpose entirely. Have you seen/used a wearable computer? Probably not. I had the opportunity to use one about 3 months ago at a demonstration put on by one of the leading researchers in the field from Georgia Tech. For the applications that are possible with wearables, a new OS may be the best answer.
  • After reading some of the responses, I'm going to slightly modify my stance...

    Current wireless solutions are not enough, unless you happen to live in one of the major cities which are offering unlimited wireless access.

    Though, I must also admit that things are improving greatly. It looks like my area may be getting such access sometime in the near future (next 6 - 18 months). The spotty coverage is still less than ideal, though.

    As far as LAN wireless, those products exist and are pretty good already. My main concern was coverage while not at home or office - which is still an average of 5-6 hours a day, sometimes more.

    Anyway, thank you for the pointers... AT&T doesn't offer it here yet, but there is a chance for someone to offer it in the future!

  • If Linux or any *nix variant (BSD, etc.) could be ported then of course it would be simpler. However it may be that only a brand new "from the ground-up" OS will really work. Linux still remains either graphical (i.e. point/click - KDE/GNOME) or command line; neither of which are suitable for a wearable system. Unless of course one enjoys talking to oneself all day. The bottomline is once the hardware is available new methods need to be examined. Recycling the old ones based on brand loyalty is the "shortsighted". Having tested a few designs I can conclusively say that neither voice-only nor mouse/hand controls will move this technology further. For something like this we must truly get "out of the box" ---quoth the Ranger

  • Ham radio systems have a pretty good potential for allowing data to be transfered back and forth between your wearable and your "home" base. The speed is slow but you can send tcp/ip packets over the system. Plus, ham radio's are pretty much have a global coverage. The negative thing is that the speed is pretty slow.
  • AT&T's (and OmniSky's coverage) is pretty much limited to major metropolitan areas, which is fine for my purposes. (I travel on business occasionally) The Ricochet system another poster mentioned is unfortunately pretty much a geographically limited novelty.

    I've been considering building my own Wearable for a while now. (off and on)

    I'm leaning towards something around the power level of the Palm Vx or Handspring Visor Deluxe (the Springboard port has definite possibilities) with text to speech hardware. I haven't been able to try out any of those one-handed keyboards, but I would think that a braille keyboard (6 keys plus space, used 3 per hand could be broken apart and set 3 keys to a hip (or palm) for data entry in a pinch.

    Then again maybe that onhandpc thing had the right idea in only really gearing up for data retrieval rather than data entry.

    I considered using the Qualcomm pdQ as a base for one at one point, except the pdQ has its own proprietary undocumented connector and appears that Qualcomm is going to drop support to move to a CE platform. (Also, it doesn't help that the pdQ only transfers data CDMA (14.4kbps and the only carrier in my area that supports it is Sprint, and they charge by the minute)

    Using a PDA for the heart of it would allow me to remove the 'getup' and still carry the information I want.

    My journada has too much bulk for me to consider carrying something like that as a starting point.

    I have a bunch of serial controllable LED displays that I could use for information sources

    That parachute PCMCIA adaptor for the palm might be a place to start, when they ship it atleast, but that would rule out a handspring module and it probably would require some jerrymandering to fit together with a CDPD modem in place.

    The question is then if I can fit a dual serial uart and a speech synth chip into a springboard module.

    And dangit, this still won't let me play mp3s =)

  • No, I'm not sure.

    AFAIK the distinctive point about Microkernels is that cricical subsystems (filesystems, memory management policies, process scheduling policies etc.) are handled by user-level processes.

    NT has a lot many services, its IPC setup is most impressive (I think it's because Microsoft tries to offer (N+1)-thousand way of doing things because they can't get the first N-thoudsnd right but need to support them anyways), but I haven't seen anything like "filesystem-as-a-process". From this point of view, Linux (with its nfsiod "processes") is more akin to a microkernel than NT is.

    About whether a microkernel is better than a monolithic one. Some time around 1994 there was a very famous flamewar between a certain... what's his name... oh yes. Torvalds. Linus Torvalds, and a professor Andrew Tannenbaum (or was it Tannembaum? not sure), author of the Minix OS (and of the Amoeba distributed OS, but I've never seen any reference to it but in a Tannenbaum book). The Torvalds guy argued that Microkernels are but an academics' toys, because the advantages they offer don't hold in real life(TM), or at least aren't worth the effort. Tannenbaum of course defended microkernels (he is an academic after all), in fact both Minix and Amoeba are designed as microkernels.

  • Stuff like wearable computing is perfect for opensource, and perfect for flexible, lightweight solutions, because nobody today knows what it's going to mean to "wear" a computer because nobody can imagine all the realms of possibility that open up.

    In a sense, much of what we've seen of computers today was predictable: the Dick Tracy wristwatch, Flash Gordon's viewscreen technology, etc. If the future were that simple to predict, WinCE might have been the answer.

    But what's going to make an "ultraportable" successful is going to be a surprize. The PalmPilot won in the handheld category just because it was a better product, but it's a really subtle thing to describe exactly what is better about it. Yet, hold it side by side to a WinCE device and in about 60 seconds you prefer it, despite its paucity of apps. And that kind of subtle usability attribute is really hard to predict, even for the developers. I expect [hey, it's not exactly profound] that wearables are going to have many of the same attributes, or even more. It'll be like trying on shoes: this one pinches... ahhh! this one feels comfy. Having a variety of robust, mutable opensource OS and app solutions available to play with is totally key to allowing the widest variety of Gyro Gearlooses to experiment with kooky quirky variations, but there will be a buncha cool stuff coming out the other end.

    I was thinking the other day that the automobile was invented, looking back, pretty far into the last century. But we think of them as a 20th century device. I think in 20 years computers are going to seem to have undergone as rapid an advance. Yeah, there were some primitive devices available back in '99, and in "aught one", but nothing like what's new for '19!!

    note: I'm also predicting that we'll be back to using 2 digits for years again, lickety split, but that's off-topic.

    Sub-vocalization is definitely the cooler of the two options though.

    • There are content restrictions on what you can send over ham radio. No encrypted data, no profanity, no nothing.
    • Your range isn't much better than line-of-sight on any band where you can get serious bandwidth. On the HF bands which do allow DX regularly, IIRC you are limited to very low speeds; it used to be 65 WPM Baudot (!), but it may be as high (yeah, high) as 4800 BPS now. You just don't have the bandwidth to play with when your entire band is only 300 KHz wide; you have to play nice and share, or else you aren't operating for long.
    • You can't do anything at all commercial.
    • Anyone can listen to your traffic.
    Ham radio, especially in the HF bands, just isn't suited for what you need for wearables.

  • Look, everything that people seem to think is bad about linux/windows/etc... when it comes to wearables is part of the interface, NOT the underlying architecture.

Why throw away a perfectly good kernel?
  • The power issue is a good point, but switching CPU's only goes so far. A really powerful chip capable of serious number crunching is usually designed on the "power is irrelivant, speed is everything" model of chip design. The more transistors you pack onto the silicon, the more power your going to drain. So when it comes to wearables with real processing power, your going to need to carry along real batteries.

    Here at UofT, we have wearables based on various flavours of X86, and the strong arm, and though the strong arm is a bit more battery friendly than the equivalent X86 chips, it's not that big a difference.

    Batteries are old tech, we need to invent something better. Oh, and while we're at it, can we please hurry up with the fusion already? ;)
