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.
