What is TOUCH SCREEN?
- It is a computer display that enables the user to interact with the computer by touching areas on the screen.
- The term generally refers to touch or contact to the display of the device by a finger or hand. TouchScreens can also sense other passive objects, such as a pen.
WHEN and WHERE was TOUCH SCREEN ORIGINATED?
In 1971, the first "Touch Sensor" was developed by Doctor Sam Hurst (founder of Elographics) while he was an instructor at the University of Kentucky. This sensor, called the "Elograph," was patented by The University of Kentucky Research Foundation. The "Elograph" was not transparent like modern touch screens; however, it was a significant milestone in touch screen technology.
- In 1974, the first true touch screen incorporating a transparent surface was developed by Sam Hurst and Elographics.
- In 1977, Elographics developed and patented five-wire resistive technology, the most popular touch screen technology in use today.
- 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 touch screens for kiosk systems in retail and tourist settings, point of sale systems, ATMs, and PDAs, where a stylus is sometimes used to manipulate the GUI and to enter data. The popularity of smart phones, PDAs, portable game consoles and many types of information appliances is driving the demand for, and acceptance of, touchscreens.
WHAT IS DUAL TOUCH SCREEN LAPTOP?
A dual-touchscreen laptop is a computer display setup which utilizes two screens - either or both of which could be touch-capable - in order to display both elements of the computer's graphical user interface and virtualized implementations of common input devices, including virtual keyboards.
Usually, in a dual-touchscreen computer or computing device, the most persistent GUI elements and functions are displayed on one, hand-accessible touchscreen (changing with the software application in use) alongside the virtual keyboard, while the other, more optically-centric display is used for those user interface elements which are either less or never accessed by user-generated behaviors.
