Hitachi Demos a Stylus-Friendly Capacitive Touchscreen 47

dk3nn3dy writes "Hitachi Displays have developed a capacitive touchscreen which converts input from a non-conductive object into electrostatic capacitance. This enables it to be used in a diverse range of ways, such as multi-touch using several fingers, with a plastic pen for finer input, and in cold places while wearing gloves. The display is currently under development for release in the second half of 2011."

    Finally, the Korean Sausage people [] can eat their sausages and still use their phones in cold weather.

      Whoever marked the parent offtopic needs to hand in their geek credentials. The screen described in the article is there to solve /exactly/ the problem that the Koreans were using sausages for - they needed a conductive stylus to use their capacitative screens in cold weather without removing gloves.

  • Anything like this [] (btw, I do have an RCA player and about 30-40 movies; player just needs a new needle otherwise it's awesome good).

    ...pressure sensitivity? Because that would be something to write home about.
    • Pressure sensitivity would be nice, but even without it, it is a very welcome improvement over touch-only interfaces.

      Stylus based input is a critical feature for many uses of a tablet. Without it, and the innovative features it enables, they hold no advantage over a notebook.

  • When it comes to capacitive screens and associated gadgets, battery life is where help is needed. Whoever comes up with technology to extend battery life will reap big. Who wants to recharge a gadget every night? Who has that time to even remember? Should we all carry extra battery packs just because we own a smart phone?

    I'm skeptical this will make it to phones. Dunno if anyone noticed that they are PROJECTION-type capacitive displays. This maketh me think small devices no worky with this.

    I live in Minnesota. Pity me. That said... You can't use your phone with the gloves we wear up here. You can't even smoke a cigarette in proper winter gloves. The rest of the time take the gloves off! Maybe if they build a phone with a 17" touch screen then I'll consider using it with gloves... but by that point, it won't fit in my pocket, my purse, etc. These people need to think about the human interface a little bit more. Capacitance screens that require finger contact is a good thing... it keeps butt-di

      How about gloves with little stylus bumps in the ends of the fingers? It just has to be enough to provide a reliable contact patch.

        Okay, you're not from around here so let me explain Minnesota winter to you:

        Imagine drinking battery acid. That is what every breath feels like in January. Now add to that about 6 layers of clothing, so thick that if separated from your person could fill roughly the same space as you. You look like the Stay Puft Marshmellow Man from Ghostbusters. And you know what? It still feels like someone is pouring crushed ice down your back. If you have a dick, it is shriveled up and clinging to the inside of your pants leg and looks like a stack of dimes. Tits, if you have them, are so painfully sharpened they could cut glass.

        Now, do you really thing a reliable contact patch is what an all-weather phone needs? Please! In January, my car's happy little voice that greets me in the morning sounds like it got fed the wrong way through a tape player. The GPS speaks in tongues for the first 20 minutes of the trip.

        Touch-sensitive phones have limits. Specifically, anywhere north of southern Illinois.

        • May I suggest a one way trip to Mars? [] It could be an improvement. Either that or you keep your phone where the sun doesn't shine and get the benefit of a smaller surface area to keep warm.

      Well no worries then. If it really is that cold, it's probably outside of the operating temperature for ANY touchscreen device and probably even for the LCD itself. Your typical resistive touchscreen probably won't work much below -15 to -20 and the typical capacitive touchscreen will probably give out even sooner.

    This is going to be great for people who need mouth sticks. I have a friend with cerebral palsy. She plays Nintendo DS games just fine with the resistive touch screen, but using a phone or any other capacitive screen device is nearly impossible.
    • Er. Why not use a mouth stick fitted with a capacitive tip? Given how those capacitive styluses are just a buck or two a piece, surely attaching one of those tips on her existing mouth stick would work.

  • This will be very welcome on my bike where I must use an expensive GPS just because an iPhone won't work through the gloves. The iPhone is an excellent motorcycle touring companion -- it runs GPS, streams and plays music (not to mention the phone and internet functionality on stops.) But it is severely limited because it won't play well with gloves.
  • I'll be the first to concede that it was hell at first, but I've learned over the past year or two how to make remarkably precise selections with my stubby sausage fingers on a capacitive touchscreen. It's all a matter of personal preference, but for me it would be more of a hassle to fumble around with a stylus these days than it would be just to poke at the thing until I get it right.

    when it's covered in blood []?

  • Maybe now my next phone can have the actual no-BS usefulness of resistive touch with the Appletastic feelgood shiny warm-n'-fuzziness of being called capacitive touch! No need to compromise!

  • Does this act much like the new touch screens on the droids? I know the newer droids have a way better touchscreen than the older, 1st generation ones.
