What is the precise definition of TOUCHSCREEN?
Answer:
Here's going on for as technical as I could find:
Touchscreens, touch screen, touch panels or touchscreen panel are display overlays which are typically either pressure-sensitive (resistive), electrically-sensitive (capacitive), acoustically-sensitive (SAW - surface aural wave) or photo-sensitive (infra-red). The effect of such overlays allows a display to be used as an input device, removing the keyboard and/or the mouse as the primary input device for interacting next to the display's content. Such displays can be attached to computers or, as terminals, to networks.
A CRT peak with which an hand can interact by touching icons displayed on the eyeshade, rather than through a upright or mouse.
A monitor (LCD or CRT) with a environment to sence touch and pass that facts along to the mouse. There are different ways of doing this with LCD and CRT monitors, but they are adjectives touchscreen. Using this definition, PDA's and similar devices have touchscreens.
A monitor peak that can detect and respond to something, such as a finger or stylus, pressing on it.
