Article: Touchscreen technologies in phones
Introduction:

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.

The present article deals with all of these, used in the mobile phone industry; we’ll see what they’re sensitive to and what are their pros and cons. We’ve wasted enough time, so let’s get started.

A little pre-history of the different types of technical methods, used in touchscreens:

The beginning:


The father of the touchscreen technology is 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.

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.

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.

13. unregistered

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/index.html kthxbye

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!!!

the iphone so far has the most advanced touch screen

i agree, i like the apple Touch UI its sweet, just wish the phone part of it was better. ( i drop hella calls)

Any updates here? Even in 'full'-search in the Phone Finder, you don't have the option to search for infra-red as a screen technology, at least as-of yet. Has there been any more progress made with infra-red touch-screen tech? Or have they made further gains with capactive-screens to close the gap between the two?

WOULD like an update to this article in regard to what I mentioned in my earlier comment. Actually found it really neat when I first read it...
