A Sticky Touch Screen Lets You Feel the Buttons
mikejuk sent one in that sends absolute shivers up my spine. "I have a problem with sticky touch screens — whenever I try to clean the jam off I activate and use a lot of apps I never intended to. However it looks as if sticky is the way of the future. A prototype screen has been shown that varies the friction as you move your finger across it. The result is that you can 'feel' the buttons and notches on scroll bars. It sure beats having to build real buttons..."
So "jam" is what they're calling it now, eh?
from all activities that could um make the screen sticky.
You got the touch!
Androids are always sticky anyway, so the feature wouldn't work.
There are a lot of users out there with sticky keyboards.
Those keyboards didn't start out sticky. It's best not to think about why they are sticky. And wear gloves if you have to touch the keyboard.

Turn it off and clean it? Or am I missing something.
is just fancy talk for "This stuff is leading directly to sexbots. You'll thank us later."
"Instead of embedding lots of transducers across the surface of the panel the system tracks the figure position and simply turns the vibration on and off. "
Bye bye multitouch?
Touch screens that "bulge" out at arbitrary places where 'haptic buttons' are placed. That are pressure sensitive, and that you can feel going down when you push them.
Friction alone is not much feedback. We also need to know when we've pushed a button.
...the lack of tactile feedback.
For what I used to call mouse guestures - I don't know what to call them now that a mouse isn't involved any longer - a touch screen is great. Just wipe, swipe and pinch all you like and it works great and intuitively. For pushing buttons... not so great in my opinion, and even less if you don't get an immediate feedback (visual or auditory) telling you if the button press have been registered or not. And don't even get me started on the on-screen-keyboard thing... combining lack of tactile feedback with the joys of pushing your fingers into a non-yielding surface. It may be okay for some, but not for me...
Everything in the world is controlled by a small, evil group to which, unfortunately, no one you know belongs.
The problem with this kind of technology is that you already have to touch the screen to feel the difference. There's no "hover" on a touchscreen, if you're sliding your finger over the screen you're already scrolling the page (which means you won't feel the edges of buttons or scroll bars, since they're moving along with your finger) or clicking and/or selecting all kinds of random stuff. Which kinda misses the point of improving touch interaction.
Did you read the article? While this isn't the same as a raised button, it is definitely a form of tactile feedback. I think the biggest issue with this form though is that it only appears to work for one finger.
I've had a sticky touch screen after viewing porn many times.
I see... Seems like you were clearly holding it wrong.
...I've lost the bleeps, I lost the sweeps, and I lost the creeps.
And I don't see a single one posted yet.
Well, am I?
Buttons provide tactile response about location and success of triggering a function. Both aspects are quite useful for things like accessibility, but I still prefer the knowledge of having hit a button on a cell phone keypad or qwerty over the use of a touchscreen where I have to constantly be looking at what I'm typing.
The biggest thing I'd want feedback for is knowing where to put my finger, and that doesn't get helped at all with this, because it happens when the finger's already touching it, and in fact only when it's moving. Aside from that, help moving a text carat would be great, I suppose, but I don't see most of the rest being useful.
It also only works while the finger is moving across the screen. This technology relies on the differential formed by varying between vibrating and not vibrating. You can't have a differential if you're just tapping the screen.
"If a nation expects to be ignorant and free in a state of civilization, it expects what never was and never will be."
TFA indicates that the screen vibrates to create a thin layer of air between the finger and the screen. That results in low friction. When the finger "touches" a button, the vibration stops, the finger "touches down on" the screen and the friction increases, telling the finger and the brain that a button (or a notch on a scroll bar, etc.) has been reached. That differs from currently-widely-available haptic feedback because the vibration is in the screen itself and not the entire device.

This is conceptually the same as how a wiimote throbs when the pointer moves over a button or active region. It's a nice bit of user interface, definitely, but is far short of what's needed for a replacement of a keyboard or gamepad.
It's useful for text entry actually. If you tap the wrong key you just shift left or right and the feedback tells you when you can lift your finger - after a few times you'll probalby do this automatically. It beats the current method where you have make sure the finger has rolled enough, though the enlarged popups help (on iOS) since it's easier ot see. Also on iOS, you can touch the punctuation shift, drag over to the character you want, then lift which types that character and resets back to alphas.
If you just use hunt and peck on a touch screen, then yes its utility is limited. But if you try to use the assistance the OS is giving for onscreen keyboards, it can help out a lot.
Can I wear gloves
Why would you be dragging your finger across the screen, looking for a button? If you were already touching the screen, how would you then 'press' the button?
My touchscreen is sticky, but I guess it has more to do with reading the news while eating honey toasts at brekfast.
It's called the Swiss Army Mouse, because of it's color. It came standard with the AT&T Teletype 5620 graphics terminal in the mid-80s. I've still got mine. (I used to maintain the Usenet comp.terminals.tty5620 FAQ on them.)
i wonder if something similar could be done using static cling effects. But then i guess that would mess up the use of Capacitive screens (unless the system was clever enough to eliminate the noise from the active sections).

This is the method that the Wiimote already uses to let you 'feel' the buttons or letters on the screen. It works well. When you get the edge of a button, you feel a 'bump'. From reading the article, this appears to be exactly the same thing, except on a touch-screen.
From the description this sounds the same as Alpine PulseTouch which came out for their in-car media units several years ago
