Touchscreens are everywhere we look these days, but they've actually been around for a lot longer than you might think. Touchscreens first gained some visibility with the invention of the computer-assisted learning terminal, which came out in 1975 as part of the PLATO project. Touchscreens have subsequently become familiar in everyday life. Companies use touchscreens for kiosk systems in retail and tourist settings, point of sale systems, ATM s, and PDAs.
Touchscreen are idea to be used on kiosks because you can secure all other system hardware in the main body of the kiosk which is protected, and only the touscreen is visible, which doesn’t have any moving parts and is less lightly to get damaged or vandalised by public use, than say a keyboard.
Touchscreens provide fast access to any and all types of digital media, with no text-bound interface getting in the way. It takes time for the user to grab a mouse or use a keyboard or trackball and coordinate it with what needs to be activated on the display. It come naturally to people to point to what they want, we learn this as babies, so people usually instinctively know how to use a touchscreen.
Users feel that onscreen buttons press and release similar to mechanical buttons. In addition, tactile effects can be synchronized with sound and graphical images, creating a more engaging and multisensory experience.
All this leads to swifter and smoother usage by users of the touchscreen. Faster input can mean better customer service in restaurants, hotels, movie theatres, and retail stores, which results in increased customer loyalty.
Touchscreens are monitors that usually have a textured coating across the glass face. This coating is sensitive to pressure and registers the location of the user's finger when it touches the screen. The touchscreen has four wires (one from each corner) that connect to the mouse port on the PC. By touching the glass front, some of the natural electric charge that you hold is passed to the four wires. The driver software then works out (from the different charges on the different wires) where you touched the screen and tells the computer that you have "left clicked" there.
Other touchscreens use invisible beams of infrared light that criss-cross the front of the monitor to calculate where a finger was pressed. Pressing twice on the screen in quick succession simulates the double-click action of a mouse.
Touchscreen Kiosks are now ubiquitous, showing up in banks, casinos, restaurants, hotels, airports, hospitals, you name it. Once considered expensive and finicky, Touchscreen technology has matured, and become more reliable, more flexible, making touchscreens the idea solution for use in kiosks.
