A brief history of Computer screen Design

While developers have designing screens since a cathode ray tube display first on a computer was connected, did more great interest in the application of the principles of good design does not begin to emerge until the screens to early 1970s, when IBM introduced its 3270 cathode ray tube text-based terminal. The 3270 was used on countless ways in the Office, and company-specific guidelines for good screen design occasionally began to surface (for example, DiMatteo and Galitz, 1974). However, usually at this period had little to guide the design because it was driven by hardware and telephone line transmission issues. A1970â € ™ s screen usually consisted of many fields with very cryptic and often incomprehensible captions. It was visually cluttered and often possessed a field command that the user to remember what had to be keyed into the challenged. Multiple messages often requires a reference manual to interpret.

Make effective use of this kind of screen requires a lot of practice and patience. Most early screens were monochromatic, mostly present Green text on a black background. At the beginning of the Decade, guidelines for screen text based design were finally available (Galitz, 1980) 1981 and many screens began to take on a much less cluttered look by concepts such as grouping and alignment of elements, as shown in Figure 1.2. User memory was supported by providing clear and meaningful to display field captions and by using commands on the screen, and that they can be applied by means of the function keys. Messages also became clearer. These screens were not completely clutter-free, however. Instructions and reminders for the user had to be enrolled on the screen in the form of questions or completion codes tools such as the PR and SC. Not all1980â € ™ s screens looked like this, however. In the 1980s, 1970s-type screens were still being designed, and some live in old systems today. The advent of graphics made another milestone in the evolution of screen design. While some basic design principles have not changed, such as groups and alignment, borders were made available to the groups more visually appealing and buttons and menus for the execution of commands replace function keys. Multiple properties of elements were also given, including different font sizes and styles, line width and colours. The input field was complemented with many other types of controls, including list boxes, drop-down combination boxes, spin boxes, and so on.

These new controls were much more effective in supporting € ™ s now a persona, simply allowing for selection of a memory list instead of requiring a enter remembered. Completion aids disappeared from screens, replaced by new listing controls. Screens can also be simplified, the much more powerful computers able to quickly start a new screen. In the 1990â € ™ s our knowledge about what makes effective screen design to expand further. In combination with increasingly better technology, the result was even more improvements in the touch screen user-interface computer as the new century dawned.
