GRAPHICAL USER INTERFACE GUI PRESENTED BY JANINE MANUEL

What is Graphical User (GUI)? A graphical user interface (GUI) is an interface through which a user interacts with electronic devices such as computers, hand-held devices and other appliances. This interface uses icons, menus and other visual indicator (graphics) representations to display information and related user controls, unlike textbased interfaces, where data and commands are in text. GUI representations are manipulated by a pointing device such as a mouse, trackball, stylus, or a finger on a touch screen.

Characteristic of GUI? CHARACTERISTIC Windows Multiple DESCRIPTION windows allow different information simultaneously on the user's screen. to be displayed Icons Usually icons represent files (including folders and applications), but they may also stand for processes (e. g. , printer drivers). Menus bundle and organize commands (eliminating the need for a command language). Pointing A pointing device such as a mouse is used for command choices from a menu or indicating items of interest in a window. Graphical elements can be commands on the same display.

TYPES OF GUI: Tool User Interface (TUI) Desktop User Interface (DUI) Process User Interface (PUI)

What is Tool User Interface (TUI)? TUI, THE “TOOL USER INTERFACE” IS THE MATURE ONE. WE’RE NOW USED TO WHAT WE WERE SERVED AT FIRST, AS CAN BE SEEN FROM THE CRIES OF PROTEST WHEN MICROSOFT MOVES AN EDIT BUTTON FROM ONE PLACE TO ANOTHER. USABILITY INEVITABLY BEING MEASURED BY HOW EASY IT IS TO NAVIGATE BY AN OLD MS WORD SCRIBE.

What is Desktop User Interface (DUI)? DUI, THE “DESKTOP USER INTERFACE” IS STILL NOT QUITE MATURE, HENCE THEME OF A MILLION BLOG POSTS, THOUSANDS OF UI WEB SITES, “EXPERT CONSULTANTS” AND EVEN CONFERENCES. NOW IT’S ABOUT MAKING THE TOOL CABINET FULL OF TOOLBOXES EASY TO NAVIGATE.

What is Process User Interface (PUI)? PUI, THE “PROCESS USER INTERFACE” – SO FAR THE AREA OF SIMPLE OS PROCESSES LIKE “INSTALL NEW PRINTER”; PURE STEP BY STEP PROCESS, BUT AS OF LATELY, QUICKLY SPREADING IN THE FORM OF IPHONE (AND OTHER MOBILE DEVICES) APPS.
