Touchscreen monitor can be caused by physical contact; using your finger or stylus. In short, the human hand replaces the function of keyboard and mouse. The touch component can also be manipulated. Functions multi-touch allows the user to move, to touch, to increase and to terminate only with his hands.
Probably you enter in the interaction with most touch screen monitors, and then you realize that day. You can find them almost anywhere: the best console for games, videos, smartphones, kiosks and ATMs.
How do they work? In short, it’s complicated. However, to simplify things, divide the touch screens on two of the most obvious types.
Rezystywny touch screen is a simple and basic model touchscreen. The screen consists of two layers of glass. Layers facing each other and separated by a thin air gap. A stylus or finger presses on the outer layer, making contact with the inner layer. Creates a mount point and produces a voltage that is read on the processing tab. This connection point is now just a button advanced technologies.
Rezystywne touch screens are used in high volume environments such as restaurants and airport, because of their strength, water resistance and low cost. They also work in the video games industry. Nintendo uses this type of screen, especially with the portable Nintendo DS .
The study volume, more complex. The screen consists of glass coated with a thin transparent layer of Indium tin oxide, which acts as a guide. Since the human body is also a conductor of electricity, contact produces distortion in the electromagnetic field, which reads out as the change on the screen. Although the touch screen is much more accurate, sensitive (as noted by half of smartphone screens) and, as a rule, requires skin contact.
Why should I get a touch screen?
The advantages of touch screens noticeable. More intuitive. No need to remember shortcut keys. Because physically oddziałujesz directly on the screen, which significantly reduces the computational time. The physical movement of something more instinctive than the burial of the head and a blow to the keyboard, to the same effect.
You can’t deny the accuracy of using the stylus; especially for drawing and art. It is a requirement to students of animation and graphic design were skilled in the handling of touch screens.
In addition, there is no need for additional equipment and eliminates the installation time. No need to hard surface relied on a mouse or trackpad .
A disadvantage of touch screens cannot be mitigated with the wave of a hand. Some feel the difficult learning curve; clunky little buttons, you can’t use gloves, etc. Natural oils from your hands also defer; inevitable but can be combated with screen protection. Most will say that it is a little push in the way and requires just more cloth screen cloth.
The gorilla hand is a condition when excessive use of hand movements with the monitor, which causes fatigue. Most will never experience, while touch screens are generally not as tiring to maintain this phenomenon.
Touch screens seem more expensive in General than in respect of their non touch counterparts. Monitors typically cost from 100 to 300 DOLLARS more.
Finally, touch screens have shorter battery life . Require more energy and consume more battery power. As a rule, crosses the hour of time that for some it may not matter to others, it’s a cracker of a deal.
History of touch screen monitors and look to the future
Touch screens go further than you can imagine. They were first mentioned in 1965. Invented and EA Johnson. In 1968 published article wspomniały about the benefits of technology touch screens in the industry of air traffic control. CERN was next to the existing production model in 1973 And in 1982 . Invented the resistive touch screen.
The development of the technology of touch screens has blossomed in the eighties, today, because of the need of many other industries to introduce a new invention: industry, medical, games, videos and car were pioneering the technology of touch screens.
The next logical question is, which touch screen technology will replace the screens without touching. Most will say no. Danger shoulder gorilla, oil, used surface damage and a higher cost will prevent a large minority of consumers. However, the industry goes through change everyday. In the near future we will see touch-screen technology that uses other parts of the hands, ankles and nails to control other functions.
