Handhelds Hardware

The Dream Handheld 155

Posted by michael from the tricorder dept.
Reader samjam sent in an interesting piece about his dream handheld PC, sort of a cross between a subnotebook and a wireless web pad, with the kitchen sink thrown in. Mmmmm, light-emitting polymers. I can't decide if this kind of thing is right around the corner or just a fantasy - after all, normal notebook computers sell, and at a nice high premium - and web pads are less than successful - why would anyone spend the money to develop a device like this?
samjam writes: "My dream handheld is not available though some things come close. The technology is becoming available.

Though it may take a few months, here is what I would put together if I had the chance. Including Bluetooth, IButtons, solar panels and light emitting polymer screens...

For links to other linux handhelds, try linuxdevices.com.

My ideal handheld is the size of an A4 pad of paper, so I have to hold it on my left forearm with the fingers of my left hand curled over the end. A4 gives me plenty of screen space for watching real TV, reading real books, writing real emails, browsing real web pages and doing some real showing off.

The front cover is a solar panel, but I can't decide if the cells should be on the inside or the outside to help charge it while I use it or while I'm not using it. Hard one that.

The screen is not heavy-breakable LCD but LEP (brief technical primer, more on Google) or perhaps Xerox Electronic Paper seemingly available under the name Gyricon, pictures here and slight details here.

The choice of processor doesn't bother me much; I'd like to think there are many versions available of my handheld by many manufacturers (to drive the price down) and so many processors will be available but let's pretend the first release will run on a Transmeta just to keep excitement running high.

60 GB or so should be plenty of disk space, 2.5" IDE to keep weight down.

Input via stylus or sticky finger of course, with support for Graffiti, as used on the Palm and many others, also Quickwriting as featured on Slashdot as well as regular handwriting recognition (take your pick) and other pluggable input modules with popup keyboard for those times when you just can't manage to input a tilde (~) or backtick (`) properly.

Connectivity will be provided via a multitide of USB ports (where real keyboards can be plugged), Bluetooth (useless link) in action (good link), wireless ethernet as well as perhaps as many as 4 PCMCIA slots for things that change a lot like GPRS adaptors &c, or radio and TV tuner cards. Yeah! Why not add some Compact Flash while I'm at it? And boring 100 base T ethernet.

In fact I'm going to use the mobile phone card, along with my sound system to make the whole thing into a mobile phone for voice, not just data access. Talking of phones, the built in web cam can be used for video conferencing with (for example) Gnophone.

Better stick some firewire ports on there, too, for good measure, along with a few IRDA ports pointing in a few different directions for those more subversive inter-classroom networks as well as controlling my grannies telly to show off. And talking to my old non-bluetooth mobile which I can't afford to upgrade cos I spent it all on my handheld.

It will have integrated Ibutton support for security and authentification, maybe even built into the BIOS.

What more do I need? Oh yes, an Operating System. Pick your own.

I shall be running Linux with Ximian Gnome because it looks cool (and Bill Gates was nearly right, eye candy counts for a lot if only not to distract you by means of ugliness). I will be running redhat because I find up2date (or redhat channels of RedCarpet) invaluable effort-free way to remove those exploits, and I will finally get round to playing with Rebol.

The first thing I will need to develop is some network scavenging software to grab internet connectivity where it can for syncing imap folders and news, updating "offline web pages" [yikes! MS concept there]. Code to hi-jack available SMTP relays (*cough*). Does this smell a bit like Jini or something like it? I'll need to register my changing location for Gnophone so callers can find me. Perhaps the first thing for company visitors in the future will be to checkin their Ideal Handheld to the company network.

I will load all my favourite books into it as well as the entire classical Mormon works, copies of conference talks Doctrines of Salvation, Journal of Discourses etc, along with the Bible, Book of Mormon, and all of Project Gutenberg.

What will you do with yours? Have I missed any gizmos out? Or gadgets even?"

  • For one thing, if you plan to sit it on your forearm while you use it, the solar cells can't be on the inside of the front cover (unless you live on some odd planet where the sun is underground and the dirt is transparent).
    • Holy shazbot, Batman! I need caffeine.

      Anyway, what I was trying to say is that if you want the thing to work with a fold-up solar panel front cover (and something to wrap your fingers around), you won't be able to do it on the inside (the wiring would almost demand a solid hinge; it might break otherwise, and if it's a solid hinge, it's all too prone to slip out of clumsy users' hands... if it's a flip-and-fold-in cover, you'd have to hold it up to the sun, not the position most conducive to work).
    • With all of the cool tech being utilized, why not go for the gusto and require a Tesla style power transport system. No wires, no solar cells. Probably, no cmos either...
  • Because as the technology becomes feasible this is what people will want!

    Maybe it isn't 'round the corner' or even in the near future... but if it became possible, why _wouldn't_ someone develop this? It sure looks like a KILLER product to me!
    • I haven't been impressed by the PDA/cell-phone fusions that I've seen yet, but I'd be pleased by one that incorporated some of the less bulky aspects of the original poster's dream machine with a cell-phone in a very small package.

      My ideal would actually by a "soft" device - perhaps something that could be rolled up like a square of canvas and put into the pocket. Something I could stick into my back pocket without worrying about, with IC in the fabric. Instead of trying to be an all-purpose computer, I'd be happy with the tasks which I needed most: text input/storage, image display, network/web access, voice access/cell phone, PIM, maybe a little file storage for mp3's or such. A full-featured interface for general computing would be way too much.

      I carry my cell and my Palm everywhere, and when I've got both in my pocket, I look *way* too happy to see people. I'd like to consolidate and lighten the load.

    This size is good for using the handheld, with plenty of screen space and etc.But when you are not using it it would be a nigthmare. Where would you put it? Shure you you could keep a special pupose bag, much like the ones for laptop computers. But then it would be a laptop computer, not a handheld.

    I think that a true hand held have to fit your pocket, this way you could take it wherever you go.
    • Screen size is why I don't own a PDA. It seems to me that's the only thing keeping PDAs from being truly useful these days... you just can't do much on such a small screen. As a student, I carry around a lot of A4-sized stuff anyway, much of which could probably be more or less replaced by the Ideal Handheld. So an A4-sized Ideal Handheld would be just perfect.

      But of course, if the big screen is the one thing making the Ideal Handheld huge and unwieldy, it'd be great to lose it, wouldn't it? Seems something like this [slashdot.org] would be the perfect companion for an Ideal Handheld. Losing the big screen would probably increase the battery life quite a bit as well.

        Well I not saying that the big screen per see is a bad thing. I realy think that big screen are cool . :-) But the way I use my PDA, carring with me where ever I go, they would hurt more than make any good.

        Now if I had a laptop computer, that I would use in selected ocasions, like in work or in classes. Then I think that A4 screen is a must go. This device would not acompany me everywhere, only where it would probably be needed.

        But there could be some solution for handhelds with big screens and protables also, a folding screen? How feasible is that?
      • PDA screens are not too small (according to me). I use mine to store address/phone info, keep track of my calendar, and to read from (advantgo).

        It does all of these things nicely. If it were even one cm larger it would build in the pockets of my jeans. (ok, no jokes here)

        The thing that keeps it from doing anything more than that is that it's hard to input text into it, not that it's hard to get info out of it.
    • I think that flexiiblity is what makes people want a handheld in the first place. Does anyone remember those old stereos with a walkman that popped out of them? My ideal handheld would be basically a 4-way folding palm V (thinner really).

      Basically, it would have two screens, only one of which was visible before unfolding. When opened, it would have two screens aligned side by side, and a small keyboard which unfolds beneath them.

      This way you can use it as a pda all day, but if you want to do some gaming/typing, you can sit down and unfold it and have a double-sized screen (think two palm IIIc's next to each other).

      The trickiest parts are probably 1 designing the screens so that they can appear to be right next to each other, but still fold separately so you can go single-screen mode when you're in pda mode and 2. fitting a keyboard and two screens into something you can fit in your pocket. But I have faith that it can be done, and I'd happily allow my pocket to bulge twice the width of a palm III for the privelege.
    • An A4 sized "armheld" would be pretty heavy first of all. As the "Ultimate Handheld," it is not something you would want to bring with you everywhere you go. Look to the current market for cellphones and PDA's and you will see quite generally that the smaller the device, the more successful it is. It should fit in your pocket easily. Handbags are for women and belt clips are for tools.

      That said, I don't think a single device could fill the billing of the "Ultimate" or "Ideal" handheld, since everyone has different needs and uses for such a device. In fact the "Ultimate" handheld would have to be more of a complete product line of devices, with similar features, and possibly different form factors. I think this strategy is evolutionary and not too much to ask for today.

      1) Entry level. Inexpensive (~$100), small form factor, basic functionality and expandability. Say 1 memory slot, possibly a PC-card slot? Palm m100 is a good place to look for inspiration.

      2) Mid level. (~$250) Same form factor and features as above plus color screen, 1 PC-card slot, some form of wireless connectivity, audio (MP3 of course), + ?

      3) High end (A) small. (~$300-$500) Same form factor (possibly a bit larger in size) and features as above plus video out, bluetooth headset for integrated phone (who wants to put this thing up to their face to make a call?), GPS, video

      4) High end (B) notebook replacement. ($700+) Possibly your A4 sized monster. All the features of the rest of the line plus much larger screen, possibly a hard disk (and dvd drive?). The notebook market today is splitting into 2 main factions, the small and the powerfull. This device would be designed to overtake the small notebook by offering the same functions, with better portability and usability.

      The key is that all of these devices should be similar in the sense that a user could trade up with a minimal learning curve, and not lose compatibility in accessories and software (ie same memory card type, etc.), and would gain some funcionality.

      As for OS and GUI, there are really 2 options, MS or linux. Interoperability is essential here. All of these devices must be compatible with each other AND your desktop workstation. Palm has it's place as an organizer, but in its current state is at the end of its lifetime. An Apple OSX based product could possibly sweep the market here, as their design department is top notch. Like it or not, MS compatibility is perhaps the biggest requirement for any product these days.

      As for my personal wishlist, I want to connect to a projector and show powerpoint presentations, track finances with MS money, throw away my cellphone, get directions via mapquest or MS mappoint using a gps (I get lost easily), and of course do email, keep track or contacts, browse the web, listen to mp3 etc. But i want it now.

  • Why IButtons? (Score:2, Insightful)

    by theCoder ( 23772 )
    Why use IButtons instead of a standard smart card interface? In other words, what's the advantage of an IButton over a smartcard?

    Otherwise, sounds neat!
    • IButtons are INCREDIBLY tough and resilient. Smartcards die like crazy and are very sensitive to external magnetics. We use IButtons at work and I've actually dropped one down the elevator shaft and it survived just fine, from the 10th floor no less....
  • I'd suggest making the cover clear, and using back-to-back solar cells, so the unit charges open or closed.

    Skip bluetooth, and use low/high power 802.11b. Low power when you're close to the access point to conserve power, high power when you need range. Bluetooth seems redundant and unnecessary these days.
    • Actually, you want both. They do different things. If anything, you would be able to get rid of USB in favor of bluetooth, and just keep firewire for your high speed transfer needs. Check this [slashdot.org].
      • I'm not sure I would agree with wanting both. Streaming IP based protocols, low power consumption and lower cost (don't need two wireless subsystems) means to me that Bluetooth is a lost cause. The intent of Bluetooth is easily achieved with a low power consumption version of 802.11b. There's no specification change needed, since the tranmit power is perceived as variable to the receiver anyway based on distance. Reduce the transmit power and you have the benefit of Bluetooth (dramatically reduced power consumption), but the advantages of 802.11b (increased range on demand and bandwidth).

        By using well known and standardized IP protocols, existing wired (Ethernet) implementations can easily be extended to wireless with a layer 1 change. Little or no new development is required, depending on the supported protocols in the existing stack. 802.11b is already becoming widely deployed; what value would Bluetooth add?
        • I'm sorry, but I see no reason to have my mouse and keyboard (when I need them with a device like this) to be on my network. Bluetooth is supposed to be used with Personal Area Networks, i.e. your peripherals. My mouse, scanner, keyboard, printer, joystick, steering wheel, speakers, cell phone, and pda do NOT need to be on my network, either at home or at work. That's the point of bluetooth. As for 802.11b, great for wirelss networking, but not designed for personal area network. Again, read the link I put above.
          • Actually, putting those devices on the network will eliminate KVM switches for both local and remote equipment. It would be very neat to be able to "attach" your joystick to a game machine in another country. :-) A simple thing to do with 802.11b, but kludgy with Bluetooth.

  • Of course everyone wants a Tricorder, which could do almost anything. Or one of those other Star Trek devices.

    Strangely enough the form factor on those was more like a 5x8 piece of paper. (about half the size of an A4, etc)

    Strangely, I have not really seen a PDA in that form factor, although it is reasonable. Usually they are in pocket size (or so), or else migrate to an actual laptop.

    probably would not mind something in that form factor although I would have to think about it.

    • I agree. This seems like a more reasonable size than an A4 pad. One would have plenty of room for any application, and still be able to have a video conference call in progress ... or perhaps watch the ballgame? It seems to be a fine compromise between form and functionality. I like PDAs, (don't get me wrong) but try to draw artwork for your webpage on one... it's just too cramped.

      Oh, and one more thing. With the built in networking, you could upload your data to a larger more powerful computer. Or perhaps write a napsteresque app that Borg-a-fies all like devices into a dynamic Beowulf cluster. The onboard AI would have to synchronize with it's peers so that everyone could get what they wanted, or vote to toss the CPU-hog outta the cluster (but allow you to remain if you chose to because they were working on something 'interesting'...

      I find it hard to believe that those devices on Star Trek are not taking advantage of some pretty sweeet computing resources on the Enterprise.
    • Tricorder: In less than ten years we will have the CPU power to take your PDA into the woods and have it identify every object seen in real time. Plus it could tap into the world net and download anything it could not figure out on its own. It could keep an automatic catalog of every *individual* bird/whale/tree/person you ever saw or heard.

    Thys would be a good description of a dream notebook.. not a handheld.

    I would like a handheld that I can keep in my
    pocket, and carry in my backpack easily. I dont really care much for the screen size. An A4 size is not really practical, and a smaller size would be suitable for must purposes.

    This doesnt mean the idea is not good. It is a great idea for a notebook. A notebook without a keyboard... and the option for connection a standard keyboard. the keyboard is rarely used for web surfing, reading mail, and most day to day work. The only use of a keyboard is, well... coding. So, when you need the thing for coding, just carry a little keyboard along :)
    • How is this different from a notebook?
      The point is not to replace the notebook computer, the point is to replace the tablet of paper, which, despite it's apparently ungainly form factor, is in widespread use. This will require an innovative pen-based interface, and dumping many of the things you might want to do with a notebook computer. A tablet should be for reading and writing documents, and that's all. If it does anything else, that's gravy. People are already good at using the pen/tablet paradigm, it's just a matter of not fucking it up with too many buttons and "wizards".

      I imagine something that would use PDF's as its internal format, and would let you annotate them with the pen. The primary input mechanism should be drawing letters, trying to recognize them is secondary. You should be able to upload documents (including html) from your computer, and download handwritten things to your computer. The tablet should give a much better means of organizing little slips of paper than the pile-on-desk paradigm, now widely in use.

      Remember, don't think it's a computer...it's an upgrade to paper.

EXCEPT, it's wireless, and it uses a mainframe/terminial paradigm. A lightweight processor impliments a very lightweight, compressed X11 protocol. A relatively small flash memory will provide sufficent space for the OS, and custom window management software. Everything will be stored and run from a mainframe, allowing access from anywhere, and limited loss if you happen to drop your pad. W/o a harddrive and all the assorted goodies of an overly powerful CPU, the pad would be much much lighter, and wouldn't need as much juice. Of course it could be docked into a cradle for charging, fast wired networking, and mayhaps a keyboard as well.

Why not have the manufacturers release their applications on their servers. If and when we need to use it, we simply download some applet and use the application over the web like we use applications over NFS, ofcourse for a small fee. This way we can eliminate harddrives all together from the laptop/webpad/pda/whatever ... and reduce power consumption, weight of the thing as well.

    Nice.. A little too big for my taste tho. Even the Sony Picturebook is smaller - and that's a notebook, not a "handheld" really.

    Here's my version:

    A5 sized (half of the article describes), screen only with virtual keyboard and touch screen with a GOOD metallic stylus (obviously softer material for the tip). WLAN, Bluetooth, GPRS and tri-band GSM (900, 1800 and 1900 MHz) plus HSCSD are all a must in my dream handheld, but I'll add to this that the antennas for all must be internal. Also, for the times when no wireless connectivity is available, a normal phone and LAN jack would be needed. Basically, as you can see, connectivity is priority #1.

    Moving along, I'd throw out your hard drive and replace it with a set of compact flash slots - say 4 of them and let's say two PC card slots. In those, you could put hard drive's (IBM microdrives in the CF slots and higher capacity drives in the PC card slots). You could also slam in 4 1GB CF cards in those for a total of 4GB. This is less than the hard drive in the article, but remember that this is a *handheld* and that it has net connectivity so it can use a drive somewhere else, like on a file server.

    The device would have at least 64MB of RAM and a Strong ARM CPU. If battery was no issue, I'd consider a Transmeta CPU instead but the ARM based CPU should be better for a device like this.

    TFT is fine for me. I saw some TOTALLY kick ass EL-screens on an exhibition in Tokyo last month tho. Maybe one of those.. I'd have to look more closely at the power consumption cause I'd like to get at least 24 hour battery life from this thing.

    The OS would sit in ROM. What the OS would be is a little unclear to me. You can forget Palm OS right away. Pocket PC (especially 2002) is *great* on iPAQ type devices but this one would be larger than that. Windows CE, which Pocket PC builds on, is quite nice and stable too, contrary to what you would normally hear on Slashdot. EPOC is a bitch to code for, so I think I'd skip that. For a device like this, I'd pick Linux, I think, but the GUI would have to be something custom made especially for this device because I haven't found any existing Linux GUI to be good for handhelds yet.. :/

    Speaking of GUI.. It would *NOT* be frame based. ;)
    • First off I'd want at least a dual CPU, 803.11b wireless, GigE, raid controller across a handful of micro drives, color plasma display, fold out keypad, 500MB RAM, and UPS with a backup battery.
    • Hmm...$300 laptop drive, or $2000 worth of CF and PCMCIA HDs. I choose the $300 path!
      • Well, this was a dream setup. I prefer CF because it doesn't suddenly break on you while on the road, it's completely quiet and easier to handle than a PCMCIA HD. Still, I had the PCMCIA slots there so you COULD use PCMCIA HD's if you wanted to.
  • "less than successful", I doubt it. More like they are *never* ever released. I keep looking every few months for webpads, but they are _always_ 6 months away. And every month they have more and more features, but still with a pda interface, when they have more then some laptops nowadays!!! It is crazy. What every happened to the $250 webpad that was nothing more then a X-terminal? No sound, hd, usb, 1GB cpu, fan, floppy, keyboard, serial, parallel, firewire, scsi, and kitcken sink. Back when web pads were the rage their was a good reason. They *were* cool. They were a thin as my Palm 3x. They ran forever because they only had to power the wirless network, a small ass 486 cpu, and a screen. I looked cool and it was cool. They ran QtEmbedded or some other embeded Xish thing and you could make cool little apps for it. As a X terminal you had as much power as your server did. You could write little gui apps that would control you mp3 server that pipes to your living room. (don't need no stinkin laptop speakers now!) I have been temped to try to build one myself, but I just don't have the money or the time right now. (see kinkatta.sourceforge.net) And if I was to do it myself it would be a whole lot bigger then some of the webpad/crappola laptops that are out there. So were are these? Does anyone know? One idea I had was to merge 3 or 4 palm into 1 and then write palm software for it, but there are still issues with that...
    • I have such a webpad: A Fujitsu Stylistic 1000: 486 CPU (fine for simple X / browsing), attachable PS/2 keyboard(I use the Twiddler II [handykey.com]), VGA port (for CyVisor [personaldisplay.com] or Monitor) for when the 640x480 8" display isn't enough, radio pen, PCMCIA HD (270MB comes standard, 2GB available [toshiba-europe.com]), 2 additional type II PCMCIA slots, IRDA, Serial, Parallel, and a 3750mAh battery lasts four or five hours on a charge. I'm running RedHat 7.0, but the cleanest install [the-labs.com] I've heard of is Debian. One can often purchase them surplus for around $100.

    • Wireless ethernet (goes hand-in-hand with bullet #1).
    • Voice navigation so I can browse the memo I wrote directions into while driving.
    • Programming manuals and compilers for popular platforms included with the pilot.

      All that other crap this guy mentions pretty much defeats the purpose of what a handheld is.

      Yes, but . . . Various 'e-ink' technologies hope to have 100+ dpi within 2 years, with one (sorry, no links, since I don't remember the names of the companies that I read about last week) hoping to have 300 dpi by 2005. Since LEPs will only (hopefully) be in full production for small-scale projects (car stereos, clocks, maybe PDAs) by 2005, you do the math.

      Of course, all of the e-ink projects are made to be 'seldom-write' passive displays where you change the display maybe once or twice a day. They're not at all suitable for full-motion, full-screen video (including scrolling a static page!) They are meant to be electronically-rewritable paper, NOT a replacement for a computer screen.

  • As far as ideal portables go heres my take:

    Power:
    Methane powered fuel cell, which provides for at least a months worth of continuous use.

    The Screen:
    Light emitting polymer screen is good here. Nice choice. The screen should also have some mechanism for eliminating finger grease automatically.

    Form Factor:
    A6, there should be no border, so that the screen takes up the entire front. Perhaps with fanned screens like the Psion Protoypes. (can't find a link)

    Communications:
    An array of Software Defined Radios [sdrforum.org], allows the device to keep in touch with the outside world. Depending on your current usage, they may be configured for Wireless Ethernet, BlueTooth, 3G+, TV, Radio etc. No need for multiple cards and slots. When a bug or security risk is found in any of the protocols, a simple software patch will fix the problem.

    When data is huge, perhaps something like Infiniband [infinibandta.org] over fibre optic would be useful.

    Input:
    Touch screen will be supported, along with a slide-out or otherwise concealed keyboard for when you actually want to enter some data. Voice recognition would also be nice, but only when your on your own.

    CPU
    Since were obviously way off into the future here, I would like a micro-distributed memory architecture, with approx 32 CPUs, each with at least 64 MB of memory. The CPU should probably be something like a 64bit ARM, running at whatever clockspeed is fashionable at the time. See this [dnaco.net] for similar stuff. The interconnects between CPU modules should use something like AMD's HyperTransport [hypertransport.org]

    OS
    For linux fans, the CPU the architecture would support a micro-Beowulf style mode of operation.

    For me, I'll roll my own Actor Model based system, running on a microkernel, like L4 [l4ka.org] but with better real-time response. Built in cryptography will keep ALL comms secure.

    • Bad form and all that, but I forgot about storage:
      The ram should be static, such that when the power
      goes down, the data doesn't. 32 *64 Gives us 2GB of memory. Perhaps a 100GB microdrive style disk would be apt for Films, Music and Pr0n. Along with the option of streaming data over the air, via a secure connection to my personally administered
      server (none of that .net rubbish, but if makes sense e.g. in the case of locality, nothing will be placed on the local server, unless it is encrypted by me first!)

    You're basically confusing two concepts here: handheld and notebook. The requirements are different. A notebook should be very nearly equivalent functionally to a middling or slightly wimpy desktop, with weight measured in pounds and battery life in hours. A handheld needs to be much more extremely portable, with weight in ounces and battery life in weeks. The portability/power requirements basically dictate that a certain amount of desktop-equivalent functionality be sacrificed. That said, here are some of my ideas about what would be truly ideal for each, starting with the notebook (which more closely matches your description):

    • Size and display: A4 is a good display size, but a little too big for easy transportation when not in use. Fortunately, with a flexible medium such as LEP you could have both. Basically the screen could be like those portable projection screens that you roll up when not in use.
    • Power: solar might be nice, but you're typically not going to get that much out of it. Instead of a battery, though, use tiny methane fuel cells.
    • Processor: something like a Transmeta would be a good fit.
    • Connectivity: putting USB (including, I presume, USB2) and Firewire and Bluetooth and 802.11b (what about 802.11a) makes the base system too complex. Put one low-end (USB1) and one high-end (Firewire) interconnect on board, then provide four or more PCMCIA/CF slots so the user can customize the rest to suit their needs.

    For the true handheld, things look a little different:

    • Size and display: it needs to be smaller (more portable) than today's handhelds, not larger, and the display needs to be instantly accessible without unrolling a screen. E-Ink is a good fit here, especially because it would be nice to have your agenda or to-do list still visible at a glance even while consuming zero power. The limit on screen resolution is the combination of the unit's physical size and the human eye; the dots can only be so small, so only so many of them can fit. I'd say that anything more than 320x320 is pushing the boundaries of usefulness.
    • Power: solar is definitely not going to get you anywhere. Fortunately, those methane fuel cells are small enough even for a PDA.
    • Processor: even a Crusoe might suck too much juice. I'd go with a super-low-power asynchronous-logic chip.
    • Connectivity: very limited options here. There's room for one CF card, but not two. The best hope is that they'll be able to fit connectivity logic onto something more like MMC so you can have more than one expansion slot.

    One could well argue that we should be getting away from the idea of "handhelds" anyway. Maybe we should be thinking more in terms of an eyeglass-mounted virtual display (pick a resolution and color depth) connected via short-range wireless to a belt- or shoe-mounted CPU unit.

    The one thing I haven't really talked about is storage. That's because I have some definitely "out there" views on that subject. Basically I don't think there's going to be a reason to have a lot of permanent storage in the user-facing device. Instead, the storage will be in the network - encrypted, fully distributed, accessed securely via our ever-improving network connectivity options. Sure, there'd be local storage, but only enough to boot and to serve as a cache of the data which still "lives" in the network. A modest amount of FMRAM should be entirely sufficient, with no need for rotating media and the costs - power, noise, mechanical fragility - associated with them. Maybe if you wanted to take your PDA to Antarctica you'd need something different, but before long the distributed-storage model should work anywhere in the civilized world.

    Yes, I know some people hate the idea of data-less devices. Generally this is for one of several outdated reasons:

    • Diskless workstations were deployed at a time in the past when the network technology was really not adequate to support the same user experience that you'd get with a local disk.
    • To make things worse, a lot of diskless-workstation deployments were horribly underprovisioned, with insufficient servers and switching infrastructure.
    • Diskless operation used to imply ceding control of your data (and access to it) to someone else. With modern distributed-system technology that no longer needs to be the case; you can store your data on someone else's hardware, and access it via a third party's communications infrastructure, without giving up any control or privacy.

    In short, none of these objections really apply any more. With the right technology and the right SLAs in place, there'd be no compelling reason to have a local disk.

    Outrageous demonstrations of technology should take a back seat to well integrated personal information management software.

    Unfortunately, most of these gadgets are just overpriced candy for geeks and executives. I still use a HP 200lx (80186 CPU, 2MB RAM, and kickass PIM software designed by Lotus, inc). The technology is ten years old, but was (and is) favored by doctors, lawyers, and anyone who had a serious need to manage their personal information.

    What would I like to see in a dream handheld? I would like whoever owns the copyright on the 200lx PIM software (Lotus/IBM?) to release it as open source or integrate it into a next generation handheld. Yes, I am aware that The Palmtop Paper [palmtoppaper.com] sells upgraded 200lx's. I would like to see basically a 200lx with Bluetooth, USB, backlighting, a touchscreen...

  • So many possibilities...

    handheld with projection system. It has the standard touch sensitive lcd (or LEP or whatever), but it uses a single chip reflective projector to put a *huge* picture up on any viewable surface. It's not very steady, so integrate some motion sensors in the device and some hardware to steady the projection (IR for distance to surface (image size), accelerometer for lateral stabalization).

    When the projection is running, the touch screen on the device is still the input method.

    But really, why not go all the way. I wear glasses, so give me a covert HMD. Something that can't be seen by the rest of the world, but that gives me unrestricted hands free access to my "handheld".

    Then steal an idea from MIT and put a ring on each index finger. Radio connected, position sensing, and presure sensitive. Touch the left one with your thumb and the on-disply pointer tracks with movements of the right.

  • I'm partial to the Palm sized form factor - a little larger than a Post-it note. My ideal handheld would be as follows:

    • Fuel cell or other power source that lasts much longer than current batteries.
    • A little more computing horsepower than the Palm's Dragonball processor - a StrongARM or Transmeta chip possibly.
    • Not Microsoft/Windows based - that rules out PocketPC - I will not give my money to Microsoft if they had the last computing platform on Earth.
    • An OS with modern features - proper multitasking/multithreading, memory protection, etc.
    • A UI that's designed from the ground up for this form factor. PalmOS is great as far as UI goes. Unlike a lot of people, I actually like Graffiti - I can always get a keyboard if I need to type lots of stuff, but Graffiti keeps things small.
    • An Organic LED screen (OLED). Granted we'll have to wait until the manufacturers give a decent lifetime to the blue pixels, but those are nice looking screens. Ideally the graphics controller on the handheld would be beefier than on the Palm - games are cool.
    • Lots of memory - 32MB or even 64MB is becoming a realistic option. While we're at it, install one of those one inch IBM microdrives, that should give us some breathing room for a while without making the device too big.
    • Expandability. Personally, I find that Palm's postage-stamp sized SD cards to be too small - they're too easy to lose. How about a very thin, credit-card sized card. We already have smartcards everywhere else, installing a smartcard style connector that you just slide the card into would make life easier. The Palm m505's universal connector is good for gadgets that can't be smushed into a smartcard - make things like GPS receivers & modems into sleds.
    • Wireless networking. A cellular modem (using the cool technology of the week) should be built in. It should be able to hook up with any of the major cellular networks that are available, and use the higher bandwidth standard of the week if necessary. Maybe a pen-sized module with the antenna, receiver, codecs, etc should be used, so if the user needs to upgrade, he can swap them out.
    • Built in audio. Unlike most Palms, this ideal device would have an audio DSP built in, ready to handle MP3, Ogg Vorbis, etc. It should be a general-purpose sound device not unlike a Soundblaster in desktop machines. Doesn't need a fancy speaker built in, headphones (& a mike) should be fine.
    • While keeping the device small is very important, even more important is sturdiness. Handhelds go through a lot of abuse, to the ideal handheld would be built like a tank. The screen should have a scratch-proof layer on top of it, the case should be heavy-duty plastic, at minimum, titanium would be nice. The buttons should be rated for zillions of presses, and be able to take hard hits. Water resistance (or waterproofing) would be very nice. If an IBM microdrive is in the thing, it should be in a very effective shock mounting. You should at the minimum be able to drop the device from six feet onto hard concrete without damage. Crush resistance would also be nice - people occasionally sit on their handhelds.

    OK Palm, you have my specs, get to work!

  • It's alwaus fun to dream about some product with all the top technology thrown in. It's even better when you draw it on paper. But I think this discussion (and all the companies developing these things) should focus on what a handheld DOES, not looks like. My ideal portable electronic device would keep me connected to a (fast) TCP/IP network at all times for web, ssh, mail, file transfers, and remote access to my PC. Data input (text, pointing, voice, images, or whatever it has) would be fast and accurate. Data output would not strain my eyes or ears. Compatibility with what I already have is good. It should last for a long weekend trip without a recharge. It should fit in my pocket when I'm not using it, and be usable immediatly out of my pocket -- maybe sooner with a satelite for the unit always on my wrist for immediate access to common functions. The UI needs to be flexible enough for me to map the unit's most accessible features to my most common tasks. It's not a replacement for my desktop. Beyond what it does, who cares how it does it.

    However, it struck me that there was a flaw. I can't easily hit a "next track" button or see my playlists. However, wouldn't a bluetooth equipped palm/visor etc. be able to manage that?

    Esentially it serves as a proxy UI for the media player of your choice. But, take that a bit further - why not leave the "heavy" computing equiment and comms in your bag (say 3 - 5 pounds worth) and have a stripped down "x terminal" type hand-held?

    It would contain a color camera with good resolution (a firewire camera with at least 1024x768) (actually i think 2 camera's would be cool, one pointed backwards and one pointed forward, and moveable by software to stabilize the picture)

    It would contain an array (I'm not kidding) of other sensors, but specifically accoustic sensors (ideally both soud, radiowaves and everything in between (VERY ideally every frequency simultaneously)) both sending and receiving, so it can be used to listen to people standing miles away (cellphone replacement, peer-to-peer networking, but also snooping, radar, seeing what's behind a wall ...), and even to project sounds around you (such a thing just has to beat the crap out of even the best speakers you can find) (I know sound ... radio ... totally different things ... different sensors jadda jadda jadda, but hey I'm dreaming)

It would have an wireless connection (and could function as a cell phone), headphone jack, mic, a HDD like the new iPod. Extra battery capasity, a type III CF slot, firewire, and a more powerfull CPU for surfing the net, playing MP3s, watching videos etc.

    One day...

  • Needs a Digital Radio (DAB [worlddab.org]) reciever so it can pickup audio and data broadcasts.
  • Where's the disintegration ray? I want 200 shots off a pair of NiMH AAs!

    Villa, teleport now! Villa!!
  • I have read online about organic light emitting diodes [ibm.com] and how it can be used flexibly [universaldisplay.com].. I like the thought of having a flexible computer that I can read like a newspaper. If they can do this.. then surely you could roll it up in a protective cylinder that would also house the processor, power source, HDD etc.. I also think that 60GB is a bit overkill.. Perhaps more along the lines of 10-20 GB for me.. I don't know what I would use all of the other space for... I would hold all the MP3's on different cartridges and such.. Of course, this is all extremely far in the future (as i see it) and I don't expect to do any of those things very soon. =)
  • Replace the LEP screen with a holographic projector. Just project your screen in mid-air (and of course it includes some whizzy bits that let you stab it with a finger and/or stylus to write and press buttons and things, otherwise it'd be pretty useless). The hologram would of course feel solid, so you'd know when you'd hit it. Buttons could even be made to 'feel' different to the finger when you press them depending on what they do, so a kind of squishy feel for launching applications, and a slightly spikey feel for pressing the button that formats the hard drive.

    Okay, so that's impossible right now, but in the future, who knows?

    Speaking of hard drives, if money's no object, fill the thing with flash RAM. Solid-state holographic storage would be better though, and more plausible than a holographic screen, too.

    A final plus point would be the ability to suck power out of nearby power lines. Never get a flat battery ever again, just stay near a power line! And these days, you'll only get away from one if you go out in the country on a nice long walk, in which case you'll appreciate the three-month battery life and waterproof casing.

    That would be my dream handheld.

    Oh yeah, the OS would be even more full of eye candy than Mac OS X and Windows XP put together.
  • Shouldn't it also give you the power of flight? At the very least, mine would need to incorporate a batrope-type grapnel/winch gadget that I could use to pull myself out of frightening situations.
  • I have been doing some thinkning - and came up with a way to make this device just a little bit larger than a palm III - when folded, and about A4 when opened. however, the primary problems are: pc-card slot, battery, and periferal slots.

    so the solution seems to be: when folded the device is multiple layers, and is approx. 4" wide x 6" tall. It requires a battery and HDD from an iPOD (you can look up the article on /. your self) and requires LEPs for the screen as stated.

    Here is how it folds out:

    The top layer is the upper left corner of the "page" (1 & 2) and has a single cantelevered type arm that folds it up to that position. This peice has a layer that folds out from under it to the right - forming the upper right portion of the "page"

    The next layer are the middle two portions (3 & 4) - they slide directly up - then the right half folds out from under in the same manner as the previous.
    Both of these sections (consisting of four sections of screen) complete the screen portion of the machine.

    The next is the keyboard (5 & 6)- and the right half folds out in the same way. The battery and the HDD are contained in section 5.

    (7) is the "grafitti area or the machine and also contains the USB, FireWire and external expansions adapter (which is a cable that can run to a little belt mounted square box that you can but pcmcia cards into.

    but it looks as though the whole thing when in "palm" mode will be about 1.5 inches thick...

    WTF ever - it wont let me diagram it in text (too many junk chars)... so youll just hafta revert to the lowtek method of actually visualizing something in your head :P
  • This article mentioned that webpads don't sell well. Maybe it's because people don't want a device that has an easily scratchable screen and is (generally) fragile. A webpad would be used for mobile purposes obviously. If you want to throw the webpad into your backpack and take it somewhere, why in the world should you have to worry about breaking it? Plus, when was the last time anyone saw a PDA/webpad that didn't have an easily scratchable screen. Find a way to protect the screen and make the device very shock obsorbant and you'd have a winner. Otherwise, if you're like me, $500+ devices that are broken two or three weeks down the road isn't on your the top of your wish list.
  • have your glasses project images [mvis.com] directly into your eyes? :oD
    Its coming. . . and I want it. . .

  • Connectivity - right? That's what I'm hearing. Forget the form factor. A4, ShmayFour. Think immersion. Your in the tablet. You are the tablet. No stylus. No contact. Break away from the paradigm. The above are merely a list of technologies held together with bubblegum. Yes, there is utility in assemblage, but real advances create the technologies. Don't look at a pile of parts and say, hmm, what can I make outta these? Start with the passion, the needs and wants and work backwards to imagine the technologies to make them so. I want everything to be a pair of useful glasses, maybe wirelessly connected to a primary unit the size of a pack of cigarettes - only half as thick. All input is either occular pointing or voice macros. It's my web, my phone, my reasearch library, my entertainment center. I don't want to hold anything. I can wirelessly connect to my PC when I'm around it to exchange data/programs. Everything in the smooth, rounded corner cig-pak is solid state, and it has no connectors or wires. It uses a holographic storage crystal for all information. And it will only respond to my voice/retinas.
