The popularity of smartphones, tablets, and many types of information appliances is driving the demand and acceptance of common touchscreens for portable and functional electronics. They also play a prominent role in the design of digital appliances such as personal digital assistants (PDAs), satellite navigation devices, mobile phones, and video games and some books (Electronic books). They can also be attached to computers or, as terminals, to networks. Touchscreens are common in devices such as game consoles, personal computers, tablet computers, and smartphones. The touchscreen enables the user to interact directly with what is displayed, rather than using a mouse, touchpad, or any other intermediate device (other than a stylus, which is optional for most modern touchscreens). The user can use the touchscreen to react to what is displayed and to control how it is displayed (for example by zooming the text size). Some touchscreens use an ordinary or specially coated gloves to work while others use a special stylus/pen only. A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with a special stylus/pen and-or one or more fingers.
