What is a touch screen technology?
A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. Touchscreens are common in devices such as all-in-one computers, tablet computers, and smartphones.
The touchscreen has two main attributes. First, it enables one to interact directly with what is displayed, rather than indirectly with a pointer controlled by a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device that would need to be held in the hand (other than a stylus, which is optional for most modern touchscreens). Such displays can be attached to computers, or to networks as terminals. They also play a prominent role in the design of digital appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games.continue..

According to PC Magazine a touch screen is, "a display screen that is sensitive to the touch of a finger or stylus. Widely used on ATM machines, retail point-of-sale terminals, car navigation systems, medical monitors and industrial control panels, the touch screen became wildly popular on handhelds after Apple introduced the iPhone in 2007."The touch screen is one of the easiest to use and most intuitive of all computer interfaces, a touch screen allows users to navigate a computer system by touching icons or links on the screen.continue..
Touch-screen monitors have become more and more commonplace as their price has steadily dropped over the past decade. There are three basic systems that are used to recognize a person's touch:
Resistive
Capacitive
Surface acoustic wave

1971, the first "touch sensor" was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky
1974, the first true touch screen incorporating a transparent surface was developed by Sam Hurst and Elographics.
1983: Hewlett-Packard's HP-150 was one of the first comercially available touchscreen PCs. A grid of infrared beams across the front of the monitor detected finger movements. The IR sensors would often become clogged with dust and require cleaning

The debate over resistive vs. capacitive technology in touchscreens is getting old, but still has relevance today. Initially, it was as easy as asking yourself whether you wanted to use a stylus or your finger for interacting with a device. However, refinements in sensitivity of resistive touchscreens in combination with interfaces that are optimized for finger interaction have proved that capacitive touchscreens won't take over the mobile world anytime soon. continue..
10 – Giant virtual air hockey
If you ever fancy a game of giant virtual air hockey then UI Centric’s 103″ multi touch table is for you. Using a virtual mallet controlled by the player’s finger contestants battle it out hitting a virtual puck on a Panasonic plasma surface with a U-Touch overlay. Check out people thrashing it out on a demo table at ISE Amsterdam. continue..

Today I’ve received the highly anticipated HTC Hero, the European white version (which sells on Amazon for a hefty 700 $, without US warranty), for testing. I got a few hours with the this touch screen little genie and I have now some odd feelings about touchscreen technology in general, that I’m going to share with you in this post. In past years I’ve owned several phones and played with dozens or so other models, both touch and non touch screen.The thing is that I’m not a touch screen fan, even if I’ve loved some of my Windows Mobile devices. As I see it touchscreen technology has big disadvantages, but I think this has a lot to do with my mobile habbits and may not apply to many of you, so let’s see them. continue..
