What kind of touchscreen technology is behind touchscreens that only register presses with a stylus?

These kind of touchscreen kiosks are at just about every supermarket now-- when you pay for your purchase with a debit card for instance, you must make selections as to "cash back" and "correct total," in addition to inputting your PIN number.



These screens have never worked for me by simply pressing them with my fingers. I always have to pick up and use the rubber-tipped stylus.



What is the technology driving this type of touchscreen interface?What kind of touchscreen technology is behind touchscreens that only register presses with a stylus?
I think the LCD type screen uses a touch sensitive web or fabric underneath to detect the touch from the stylus however the type of touch or multi touch screen which is licensed to companies like Apple for use on the iPhone or iPod touch uses Haptic touch technology.

The touchscreen is powered by a push, it reacts by pressure to that part of the screen. thats why if you use your finger, you are not pushing hard enough to allow it to respond. Something that is solid any thing hard actually will work with this kind of touch interface. The other touchscreen, whitch i think is the best one, is the static screen (iphone, iPod touch and some CRT monitors use static from your hands or fingers to navigate and use the interface, its more responsive than the push screen, then again not as accruate as a push, for your hand covers a wide range on the screen if you are working with smaller icons and settings.

I use my finger on them all the time. Maybe you aren't pushing hard enough.
