Touch screen monitors are display screens which can detect the location and presence of a touch within the area of display. Touch screen monitors or the term touch screen usually refers to the contact or touch on the display of the device by a finger or hand. Touch screen monitors are also sensitive to other passive objects, such as a stylus, however when the sensed object is active, as with a light pen, the term touch screen is usually not applicable. To be able to directly interact with touch screen monitors will indicate the presence of a touch screen. Touch screen monitors have two main attributes. One is to interact with the display directly, without the use of keyboard or mouse, and the second no intermediate device is required such as a stylus, which needs to be held in the hand. Touch screen monitors can be used with computers, or as terminals to networks. Touch screen monitors first emerged from academic and research laboratories in the late 1960s.
