Flexible Computers in the Future? 229

An anonymous reader writes "New Scientist is reporting on Sony bendable input devices. When computers become too small to be operated by buttons, how will we control them? The only option will be to gently bend them, according to engineers at Sony's Interaction Lab in Tokyo." The diagrams make it look like a warped Game Boy. Looks pretty cool, though.

      Mhh ? I don't really see in which way the problem would be specific to bending devices. In my pocket, a device is as likely to bend as to be compressed (clicking on its eventual buttons).

    If you take a normal piece of paper and bend it back and forth a few times, you'll find that it starts "remembering" where you bent it.

    Yes, I know they're small piezoelectric particles to generate voltage when compressed, but those can't last forever. The material of the card might start developing a memory if you bend it too much.

    However, this will be kickass if they can make them cheap enough. Imagine: walk up to a vending machine in an airport, buy a little credit-card sized game to occupy you during the flight, and throw it away when the battery runs out. Or have a book on the card - a novel and text output probably won't take up that much memory.

      You're halfway right.
      When a material is deformed by stretching, compressing, twisting, or bending (which is really a combination of stretching and compressing), there is a region called the elastic region where the material will return to its original size and shape when the force deforming it is released. Beyond the elastic region is the plastic region, where the material will remain deformed. If the material is deformed in such a way that the deformation never reaches the plastic region, the material(with a few exceptions) can be cycled (deformed and returned) infinitely without failing. The amount beyond the elastic region that the material is deformed determines how long the material will last. Think about bending a paper clip or a pencil in your hands.
      There's a whole field of study devoted to understanding this process better, and to make the existing equations fit the real world better.
      Any inaccuracies or typos are because I'm tired and it's late, feel free to correct me if you know what you're talking about.b
      • does the number of cycles have an effect on the time to failure even if the bending/twisting wouldn't normally cause plastic deformation?

        I'm sure I recall something like this in dealing with the lifetimes of pressure cylinders - the cylinder doesn't show exhibit plastic deformation, but it only has a finite number of cycles (i.e. number of times you can fill it and empty it)
        • Yes, it would. It's called fatigue failure.

          Been a while since I did out the equations, but basically, every time you stress an object above it's endurance limit, (aka fatigue limit) which is in its elastic region, you form microfractures. These microfractures propogate every time you stress the material.

          It's fairly easy to figure out the lifespan, from a ballpark figure, anyway. If you test the number of cycles to failure right at the endurance limit, for the most part, if you double the stress, you

    • The buttons that aren't really buttons are sort of like laptop trackpads. They use capacitance to detect your finger and then act. They can be fabricated quite thin (see the third generation iPods for an example), but since there is no tactile feedback telling you when the button is pressed, they aren't particularly good for touch-typing keyboards. Also, since there is no physical button to press, it is much easier to accidentally press a few buttons at a time.

Touchpads are not as good as a mouse, especially a small one. The only easy way to interface is to touch the screen on the front. Though im not sure how one gets around entering text easily...our current ways of using a stylus, moving a cursor, or pressing tiny keyboard buttons just to enter in some words just doesnt cut it. There has to be an easier and more efficient way of doing this.

An announcement comes over the P.A. system: "Due to our recent expansion to 3000 screens, our screen size has shrunk so small it's no longer visible. Please exit to the side."

    Unless the device has a different practical use than displaying information (such as playing MP3s or whatever) you're not really going to want something so tiny it's physically unusable. There's something to be said for real buttons that you can press and get positive tactile feedback.

My touchpad on my laptop didn't seem to have a large controller chip, if they could microsize that perhaps we could have touchpad-cards?
  • So, if the device has a touchpad already, why not just have the user tap the touchpad to do things like mouse clicks? Is it just in order to have more than one button? If so, I really don't see the reason. If the devices are designed to be "cheap" and have a limited life, as most of these posts have been guessing, what application could there be for it that would need more than one button? Games?

    I think those design people missed out something in their college careers. They missed out learning the principle of diminishing returns.

    Being small only gets you so far, and just because you can make it smaller doesn't mean that you should. For example, take your average ball-point pen. Most pens you can buy in a store are about the same size - a good fit for an average hand. Yet, I've seen a few "toy" pens here and there - I remember there was a teeny pen on a swiss army knife I owned. That thing was completely useless. You could attempt to write with it, but your hands cramped up almost instantly. That's probably the reason you don't see a lot of swiss army knives with pens as attachments nowdays. I'm sure there are ways of making a new "interface" for a miniature ball-point pen - for example, if you had nothing to do, you could probably attach it to a thimble and have a half-decent pen. The point is, that people don't do it. There is a thing as TOO small.

    I think handheld computers too are getting to their natural sizes with the Palm (and PocketPC) form factors. If you get too much smaller, you start squinting at the screen and there's the whole issue of diminishing utility again. Input into the thing becomes just one of your (many) issues. I had a teensy cell phone for example, and I was in constant fear of losing it in the cushions of my couch. I actually upgraded to a larger phone with more features and a longer battery life - because the size of the previous phone was a nuisance rather than a benefit.

    There are two powerhouses in the PDA industry, Pocket PC and Palm.. Sorry guys, Zaurus IMO is still a non-mainstream. Firstly I'm not gonna talk about a specific PDA or specific brand, rather PDA in general.

    In general, most people use PDAs for the address book function, and majority of these people uses the Appointment/Calendar function too. Some would also use the notes function too, but seldom. Anything extra, rest assured you can call yourself a power user. I know this for a fact because I used to work in a retail shop selling PDAs

    Let's look at features that most users want..

    Handy - Small, slim stylish design that you can keep in your shirt pockets. Not something the size of a brick, and weighs like one!

    Battery - You want something that can last at least for a few days without charging the battery (One Pocket PC brand got it right finally, by having removable batteries)

    Affordability - Most Tom, Dick and Harries don't need the bells and whistles and the extra gadgets like cameras, bluetooth, Wi-Fi, modems, large external storage. Something reasonable is probably the order of the day. All those extras costs money, house-wives don't need most of 'em in order to keep track of their grocery shopping list do they.. So are students, secretaries and bosses, normal users and joes like me ;-P

    Most of those who bought brick-like units are usually either power users (who knows what they want) or those who got too much money and wanna show off. I call these PDAs - Show-Off Units.

    Sony bendable handhelds, well, Look and see.. Price-wise, if they're out of reach, most joes won't use it. Battery-wise, too short, they're not Palm-Tops nor Pocket PCs, rather Desktop PDAs, since they're perpetually connected to their charger unit. If it is too bulky, hell no, I'm not gonna use it, cuz it won't stay in my pocket. I don't wanna look like a fully packed Llama

    In the end, I (and most joe user) want something convenient to use to get day to day tasks done

    As long as we have to physically interact with electronic devices with some part of our body there will always be buttons, switches, knobs, dials, etc. I think we are much more likely to see digital versions of these types of interface devices becoming widely adopted. Space is certainly a premium, but with any physical object you always have a back side, for example my dad was recently in Holland and his business partner over there drives a car that has the radio controls on the back side of the stearing wheel, exactly where your fingers rest when you drive.

    Not to mention forcing the general public to learn a new way to interface, which we all know is difficult, but these devices are going to have to be extremely well made to withstand all the abuse. With the rapidly dropping quality of consumer-level products I'd be quite wary of purchasing something that by it's very nature would have to go through all that.

      It comes down to this: why do we still use a keyboard today? It's not like keyboards are going away, far from it; they're actually getting bigger. Well, more buttons anyway, if not actually increasing in dimension.

      I don't think the human interface part of the computer as it is today is going to go away, or even get much smaller, anytime soon, there just won't be so much space devoted to everything else.

    I certainly have no desire to bend anything just because the guts are small. Also, if these things are expensive I don't want them to be too small anyway. Too easy to lose.
