A touchscreen is a computer input device placed on top of a display screen. With a touchscreen, a user can record or change information by simply pressing or moving their finger across the device’s surface. Touchscreen technology allows a person to directly interact with a computer, rather than requiring the use of peripheral devices such as a mouse and keyboard. The ability to skip the use of peripheral devices makes touchscreens more intuitive – meaning people can easily use them without having to learn complicated procedures involving a mouse, keyboard, or microphone.
A resistive touchscreen panel uses two layers of transparent, or clear, material stacked on top of a display. One of these layers has electronic current flowing from side to side, the other layer has electronic current flowing from top to bottom. When a user presses an area on the screen the layers are squished together, and the electronic currents intersect. The user’s finger location can then be determined by the device. This technology will be familiar to people who have used a Nintendo DS gaming system. Restaurants and factories also use this technology because it is very durable and unaffected by dirt or contamination on the surface. A resistive touchscreen can be operated by a stylus or by users wearing gloves.
