Progressive Disclosure (Jakob Nielsen's Alertbox) Summary: Progressive disclosure defers advanced or rarely used features to a secondary screen, making applications easier to learn and less error-prone. Interaction designers face a dilemma: Users want power, features, and enough options to handle all of their special needs.
(Everybody is a special case somehow. For example: Who wants line numbers in a word processor? Millions of users, that's who, including most big law firms.)Users want simplicity; they don't have time learn a profusion of features in enough depth to select the few that are optimal for their needs. Progressive disclosure is one of the best ways to satisfy both of these conflicting requirements.
It's a simple, yet powerful idea: Initially, show users only a few of the most important options.Offer a larger set of specialized options upon request. The print dialog box is the classic example of progressive disclosure. The initial print dialog box typically contains one or more buttons for advanced options. Applications vs. Operating System Interface Design Between 1981-2009. A Graphical User Interface (GUI for short) allows users to interact with the computer hardware in a user friendly way.
Over the years a range of GUI’s have been developed for different operating systems such as OS/2, Macintosh, Windowsamiga, Linux, Symbian OS, and more. We’ll be taking a look at the evolution of the interface designs of the major operating systems since the 80′s. I should mention that this article showcases only the significant advances in GUI design (not operating system advances) and also not all of the graphical user interfaces and operating systems existing today. The first GUI was developed by researchers at Xerox Palo Alto Research Center (PARC) in the ’70s.
This research opened a whole new era of computer graphic innovations. The first personal computer which used a modern graphical user interface was the Xerox Alto, developed in 1973.
