A contraction stress test is a test performed during pregnancy to verify whether or not the unborn babyâs heart is strong enough to withstand labor. It uses drugs or nipple stimulation to make the uterus temporarily contract in order to replicate labor contractions.
Graphical user interface. A graphical user interface (or GUI, often pronounced gooey), is a particular case of user interface for interacting with a computer which employs graphical images and widgets in addition to text to represent the information and actions available to the user.
Text interface with menus. 1  A text interface can be made easier to navigate using menus created with text and ASCII extended characters. For example, many command line text editors have some type of interface with menus and shortcut keys that make navigating the file being edited easier. The picture below is an example of the MS-DOS editor used to edit files while at the MS-DOS or Windows command line. Although a text interface with menus has a lot more visual appeal than the command line, this interface is still considered a text interface and not a graphical interface.
