Article: Touchscreen technologies in phones
Touchscreen phones are becoming a part of our lives more and more each day. This is due to the fact that the touchscreen control method allows a device to be navigated much more easily, quickly and intuitively, since you can activate given applications by touch, rather than having to press a button multiple times (e.g. the D-pad). There are a few different types of technology that can be used to achieve this control method, each of them having its pros and cons.
A little pre-history of the different types of technical methods, used in touchscreens:

Dr. Samuel Hurst. In 1971, while he was working as an instructor at the University of Kentucky Research Foundation, he had to read a great volume of information during the graduation exams and it took whole two months so that two students could graduate. In an effort to save some time he invented the first touch sensor that he called „Еlograph” (electronic graphics), which allowed him to enter data faster. Alongside with this invention the company „Elographics” was born (known today as Elo TouchSystems). This device was not transparent as today’s sensors are, but this achievement was a big move towards the modern touchscreen. Three years later, in 1974, Dr. Hurst designed the first transparent touchscreen, and in 1977 Elographics invented and patented the 5-wire resistive technical method, which is still the most widely used one today.

Very good story.
Just wait until the iPhone fanboys come in
Primitive technology. Wait til the Blackberry Thunder comes out. Apple fanboys will be STUNNED!
primitive? thunder uses capacitive technology..same as iphone...thunder is just setup differently

Bravo Phone Arena. Great piece and you managed not to work in a spy story or other unwanted coloring. Very educational, please write more articles like this.

I agree, this was an amazing article and I learned a lot. I however do like leaked information on phones =/
Ha, makes me want to buy a neonode 8P
very nice story...keep em coming

Yes, very good article. Informative and interesting, keep em comming!
i second #12 phonearena who are the major producors of the infared tochsceens? and the only thing ur site is missing is more articals like this one. keep em coming, please.

Wow, could you image a phone that supports all 5 fingers. I want microsoft to get into the cell phone industry themselves. That would make Steve Jobs crap his pants.
when would u use five fingers simultaneously on a phone? just out of curiosity
I'm sure i read this at the resistive touchscreen: "Unfortunately, this method cannot report more than one touch at a time" Am I right? If yes, than the writer is too uninformed. Resistive touchscreen can report more than one touch at a time. I you don't beleive, visithttp://www.simasystems.com/ind

The Neonode zForce Technology which is opitacal/infrared touch screen based can do Multitouch, has no issues in working direct sunlight, which would be the brightest of ambient lights, and also when comparing to Capacitive and Resistive touch-screens on a same production volume, the zForce Technology is actually the CHEAPEST!!!

i agree, i like the apple Touch UI its sweet, just wish the phone part of it was better. ( i drop hella calls)
thats because of the network, not the phone.
