A Capacitive Touch Screen is a display device that allows the user to interact with a computer using their finger or stylus. They're a useful alternative to a mouse or keyboard for navigating a GUI (graphical user interface). Touch screens are used on a variety of devices, such as computer and laptop displays, smartphones, tablets, cash registers, and information kiosks. Some touch screens use a grid of infrared beams to sense the presence of a finger instead of utilizing touch-sensitive input.
Touch screen history
The idea of a touch screen was first described and published by E.A. Johnson in 1965. In the early 1970s, the first touch screen was developed by CERN engineers Frank Beck and Bent Stumpe. The physical product was first created and utilized in 1973. The first resistive touch screen was developed by George Samuel Hurst in 1975 but wasn't produced and used until 1982.
What computers support a touch screen?
Today, all PCs support the ability to have a Surface Capacitive Touch Screen, and most laptop computers allow users running Microsoft Windows 10 to use a touch screen. Also, many all-in-one computers are capable of using a touch screen. Computer manufacturers with products that have touch screens include Acer, Dell, HP, Lenovo, Microsoft, and other PC manufacturers.
There are also some high-end Google Chromebooks with touch screens. However, to help keep the costs lower, many Chromebooks do not have touch screens.
How do you use the touch screen?
Tap - A single touch or tap on the screen with a finger opens an app or select an object. When compared to a traditional computer, a tap is the same as clicking with a mouse.
Double-tap - A double-tap can have different functions depending on where it is utilized. For example, in a browser, double-tapping the screen zooms the view, centered at the tap location. Double-tapping in a text editor selects a word or section of words.
Touch and hold - Pressing and holding your finger to a touch screen selects or highlights an object. For example, you could touch and hold an icon, and then drag it somewhere else on the screen. See our long press page for further information on this term.
