Touch Screen Monitors: 5 Fast Facts

Fact #1. Touch screen monitors make keyboard and mouse functions a thing of the past. They are prompted by physical contact. You can use a stylus device, or simply your finger. The touch component itself can be manipulated. Features allow you to do everything from swipe, tap, zoom, and pinch, all by using your hand.
Fact #2. There are two primary types of touch screen monitors. The first is resistive. This is the most basic model. Two layers of glass compose the screen. They face each other, and are separated by a thin gap of air. A finger or stylus presses down on the outer layer. This forces contact with the inner layer, which creates a connection point and produces voltage. The processing board reads this, and transforms the connection point into a high-tech button.
Fact #3. The second type of touch screen monitor is a little more complex. They're known as capacitive sensing monitors. The glass screen is coated with a thin layer of Indium Tin Oxide. This acts as the conductor. Physical contact creates distortion in the electromagnetic field, which is read as a change in the screen. While these units are much more precise, they are fragile, and require skin to screen contact.
Fact #4. These devices were invented by E.A. Johnson in 1965. By 1968, the air traffic control industry began to take notice of their benefits. CERN tried their hand at manufacturing a working model in 1973. The resistive touch screen finally came into play in the 1980s, and continued to flourish through the ensuing decades. Industries like medical, video gaming, and automotive are all considered pioneers of this technology.
Fact #5. Touch screens have many benefits. They're intuitive, so you don't need to memorize keyboard shortcuts. Computing time is cut considerably, since you're interacting directly with the screen. There's also no need for additional equipment. However, there are a few drawbacks. Users may experience a tough learning curve. Natural oils from hands are unavoidable, and require consistent use of screen wipes. Lastly, touch screens have a relatively short battery life, and are slightly pricier than their non-touch counterparts.
