One may define a touchscreen as an input and output device that is typically layered atop of an electric visual display system capable of processing information. It enables users to input or control the data and information through either a single or multi-touches with using a specified stylus or finger.
Certain touchscreens require the use of regular or specially coated gloves in order for them to function, while others simply need some sort of special pen or stylus. Depending on the kind of touchscreen, users can also make changes to what is being displayed such as enlarging the text font using a zooming feature.
Touchscreens also facilitate direct interaction between users and what is being displayed, eliminating the need of a touchpad, mouse, or other such devices.
Various initial concerns surrounding touch screens
Despite of their many advantages and technological capabilities, there are still certain concerns that come with the use of touch screen displays:
Dirt and damage through excessive use
Because most touchscreens are operated using finger touches or other such means, they are usually vulnerable to dirt, scratches, and damage. Once any of these issues arise, its functionality capabilities will significantly reduce.
Poor onscreen calibration
Whenever a touchscreen lacks proper calibration, it will more than likely lose its ability to provide accurate or reliable responses, and in some cases may even fail to detect touches.
Lagging operation system or software
Despite one’s efforts to, properly maintain their touchscreen, its operating system may falter on certain occasions, causing it not to recognize inputs, become slow, or just unresponsive.
The application of touchscreens in various fields
The following are some of the main areas where touchscreens are largely used today;
Touch screens are used in numerous ways in an office setting, from swiping of IDs and inputting thumbprints to gain access, to actual office computers that require simple touch gestures for data entry and confirmation of different tasks.
Media houses are probably some of the places where touchscreens are used most. This can range from reporting the weather, touching on states and numbers during an election, or when reporting on major events.
Also, with new age touchscreens, reporters in the studio simply need to touch a particular screen, and their colleague who is on location will appear as though they are right there in the room with them.
Seminars and board meetings
People involved in public speaking and firms holding board meetings often use touchscreens so that they can easily highlight certain points and aspects, which would take too long or prove impractical using a keyboard or mouse.
Automated teller machines
In today’s world, everything from withdrawing money at an ATM, to paying your utility bills is done using a touchscreen. This is because it allows for faster processing of transactions, and eliminates the need for paperwork that may lead to long queues.
Payment stations or kiosks
Malls, gas stations, restaurants, and other retail outlets typically have touchscreens for facilitating orders and payments. They are easy, more visual, and simple, thereby reducing the risk of making a mistake.
