Screen design is the design of graphical user interfaces. Screen design includes a wide variety of applications where screens or displays can be used as part of human-machine interaction. Screen design should be distinguished from the functions of a graphical user interface. Technical implementation is not part of screen design.
Screen design can be understood to be the conceiving and creating of the graphical user interface (GUI). The arrangement of the elements which can be seen on the screen is of greatest importance. This concerns primarily the layout. The concept of the information architecture is presented in detail. Location of elements such as navigation, text, headings, as well as sub-headings, images, videos and other content of the user interface is an important factor. Screen design is therefore concerned with the composition of the various elements and content, and their appearance on their respective interface.
Screen design is not only used for websites, mobile websites or apps for smartphones, but also in many other applications which have as their central element, user interaction on different screen sizes. These various output formats are challenging for screen designers, because content will be shown on different screens. This also means that certain restrictions and possibilities must be taken into account and exploited.
The features and possible interaction patterns should be supported by the graphical properties of the medium. At the same time, the overall impression of the screen display must satisfy certain aesthetic requirements. For example, the elements on the screens should have proportions, which have an aesthetic effect on the observer or user. Such aesthetics is in turn associated with the user interface and is directly related to aspects such as web design, usability or user experience.
Screen designers usually collaborate with programmers and web designers to support the features of display applications through design. They have to comply with the rules of screen design and also take into consideration psychological and technical factors. After all, screens are always part of the programming or markup language used and the possible patterns of user interaction. At the beginning of a process in screen design is always the user (See User Centered Design). Screen design is best based on the target audience. Barrier-free screen designs are therefore differently conceived than screen designs for mobile devices. Displays for children contain different design elements than those for adults.
In the course of the design process, aspects such as corporate design or technical implementation with HTML, PHP and particularly CSS also play an important role. The latter is of course dependent on the application area and the language used. Screen designers therefore often create a style guide, which summarizes and documents the patterns of interaction and visual design. The purpose of a style guide is the consistent implementation of the different requirements for different output devices, target groups and user interface features.
Style guides can consist of the following factors:
Typically, examples are created in the style guide which give the customer a concrete first impression of the graphical user interface.
Screen design goes hand in hand with technical, psychological and of course the practical aspects of a user interface. In the preliminary stages, the target group, the goal of the UI and the framework in which it exists must be taken into account. Whether website, mobile website or software application – screen design is not only about the first impression of an application, but is a key factor in terms of the graphical properties of the entire user interface. Therefore, screen design has a particularly important role in the areas of usability, user experience and interaction between man and machine. Screen design affects the conversions of websites, apps and software.
