Simple use of touch screen
A touchscreen is an smart electronic Vistula device that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or your hand.
The touchscreen has two main attributes. First, it enables one to interact directly with what is displayed, rather than indirectly with a cursor controlled by a touch pad or mouse. Secondly, it lets one do so without requiring any intermediate device that would need to be held in the hand. Such displays can be attached to computers, or to networks as terminals.
