Touch screen computers from HP

Touch screens accept input by allowing the user to place a fingertip directly on the computer screen, usually to make a selection from a menu of choices. Most touch screen computers use sensors in or near the computers screen to detect the touch of a finger. Touch screens are appropriate in environments where dirt or weather would render keyboards and pointing devices useless, and where a simple, intuitive interface is important. They are well suited for simple applications such as a automated teller machines or public information kiosks. Touch screens have become common in fast-food restaurants, department stores, drug stores and super markets, where they are used for all kinds of purposes, from creating personalized greeting cards to sell in glittery tickets. Car-rental agencies frequently provide touch screen systems at their counters so that customers quickly access and printout driving directions. Computerized touch screens also appear on slot machines in gambling casinos. Some computer makers refer to pen-based systems as touch screen systems because the user touches the screen with a pen. However, the term touch screen implies a system that accepts input by allowing the user to touch the screen with a fingertip.

A touch screen is new technology that allows the user to simply touch the screen instead of using a mouse or other input device. You simply have to lightly push on the screen with your fingers to move things around or to enable a program.
