Membrane That Turns Any Surface Into a Touchscreen 111

alx5000 writes "Engadget has a story about Displax Interactive Systems, a Portuguese company that has created a new polymer film that, when stuck onto a surface, converts it into a multitouch touchscreen with up to 16 contact points. The article states that 'if all goes well, the first Displax-enabled wares will start shipping this July.'"

    The usefulness of touchscreens is truly overrated.

    I used to work at a pizza chain where we had to ring in orders using a touchscreen. They were the biggest pieces of shit ever. It'd take five or six taps to perform any action.

    Just last week I was at the airport, and ran into the same problem using a much more modern ticket printer station that used a touchscreen.

    I can't help but be very skeptical about this technology, given how poorly existing touchscreens work. And those existing touchscreens are just basic rectangles, in very predictable and controlled environments.

      Take a look at one of the many all-in-one PCs out there with touchscreens. Hell, just look at an iPhone. They work pretty well. Now look at the touchscreen at the airport. This is a device that is touched by hundreds if not thousands of different people a day. That much constant use is going to require a lot of maintenance.

        It probably doesn't help that any touchscreen placed somewhere where the general public has access to it will be subjected to vandalism and stupidity in the form of people pouring liquids on it, banging on it and (in the case of stupidity) trying to jab it really really hard without checking if it's possible to, you know, just touch it lightly.

        I think you are comparing different technologies. The touchscreens of a few years ago were, I agree, total rubbish. But they were basically single point touchscreens with very crude technology. The multitouch screens, as used on the iPhone and iPad, are qualitatively in a different league. Instead of simple hardware recognisers, they use sophisticated software to work out what you are doing. If you haven't tried one of those, you have not seen what such screens can do.

      • Some touch screens are pressure sensitive, others are contact sensitive (like the iPhone). That's why there is such a huge difference. I would assume this layer isn't pressure sensitive, as that would need some sort of mechanism BEHIND a soft screen.

    • Touchscreens are useful for certain situations. It's like the use of Flash on webpages. There is a time and a place for Flash (youtube wouldn't have been half as good without it, for example) but when most of the Flash you see is annoying banner ads, entire websites made of Flash or 5-minute unskippable intros for sites with no real content then you start wanting to reject it completely.

      most of the touch screens used in point of sale (i.e. cash register) applications are old resistive touch films. This tech suffers from the drawback that in order for the resistance of the film to change you have to physically deform it to register a touch. This opens you up to all kinds of mechanical fatigue problems like the one you're talking about. Capacative touch systems (like the iphone) which work by sensing the proximity of your finger electrically don't have this problem. The material in the a

      Most touch screens for data entry are layers on top of the glass. This is capacitive, and can go under the glass. If it were under the glass, you'd have a much harder time wearing it out than if it were a simple touch screen like the type they use at Pizza Hut.

    You've been able to get membranes that could be put on normal screens and make them touchscreens for a long time. I remember a school where my mother worked got some in the mid '90s and put them on monitors. A bit later there were companies advertising them for putting on laptops, with a serial adaptor so you got something that looked like a serial mouse to Windows 3.11 but was a touch screen. The news here is that they now support multitouch.

    I've been trying to find touchscreens to incorporate into an embedded system, and few of the touchscreen vendors have drivers for anything other than Windows - as such they get eliminated from my consideration.

    I've just check Displax's site, and a search for "linux" gives no hits - so either:
    a) They are just doing the actual sensing system, and letting somebody else build the actual interface chips
    or
    b) They only support Windows.
