Touch Screen

A touch screen is a display which can detect the presence and location of a touch within the display area. 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 stylus. In short, the ability to interact directly with a display typically indicates the presence of a touchscreen.
The touchscreen has two main attributes.

  • First, it enables one to interact with what is displayed directly on the screen, where it is displayed, rather than indirectly with a mouse or touchpad.
  • Secondly, it lets one do so without requiring any intermediate device, again, such as a stylus that needs to be held in the hand.
