A GUI uses a combination of technologies and devices to provide a platform the user can interact with, for the tasks of gathering and producing information.
A series of elements conforming a visual language have evolved to represent information stored in computers. This makes it easier for people with little computer skills to work with and use computer software. The most common combination of such elements in GUIs is the WIMP ("window, icon, menu, pointing device") paradigm, especially in personal computers.
Windows in 1985 was Microsoft's answer to Apple's Lisa and Mac as a point and click system, eliminating the use of the typed Command Line.
Why are all the "buttons" so far apart? You have to float your cursor all over the screen to click between menus, actions, scroll, and searches. See that mouse fly off the pad! See my finger scrape across the touch pad ten times to get where I'm going! Touch screen is a nice invention for those that can afford it. I'm gonna need a remote to handle my laptop! I can't wait until the heads-up-display [HUD] interactive system is improved for personal use (I know it exists! Iron Man and pilots use it). Or skip virtual reaality [VR] altogether, and let's just "plug in" to the NET! 2009/11/11
