User interface design (UI) or user interface engineering is the design of user interfaces for machines and software such as computers home appliances mobile devices and other electronic devices with the focus on maximizing usability and the user experience. The goal of user interface design is to make the user's interaction as simple and efficient as possible in terms of accomplishing user goals.
Good user interface design facilitates finishing the task at hand without drawing unnecessary attention to itself. Graphic design and typography are utilized to support its usability influencing how the user performs certain interactions and improving the aesthetic appeal of the design design aesthetics may enhance or detract from the ability of users to use the functions of the interface. The design process must balance technical functionality elements to create a system that is not only operational but also usable and adaptable to changing user needs.
Interface design and visual is involved in a wide range of projects from computer systems to cars to commercial planes all of these projects involve much of the same basic human interactions yet also require some unique skills and knowledge.
As a result designers tend to specialize in certain types of projects and have skills centered on their expertise whether that be software design user research web design or industrial design.
User understanding of the content of a website often depends on user understanding of how the website works. This is part of the user experience design. User experience is related to layout, clear instructions and labeling on a website. How well a user understands how they can interact on a site may also depend on the interactive design of the site. If a user perceives the usefulness of the website, they are more likely to continue using it. Users who are skilled and well versed with website use may find a more distinctive, yet less intuitive or less user-friendly website interface useful nonetheless. However, users with less experience are less likely to see the advantages or usefulness of a less intuitive website interface. This drives the trend for a more universal user experience and ease of access to accommodate as many users as possible regardless of user skill. Much of the user experience design and interactive design are considered in the user interface design.
Advanced interactive functions may require plug-ins if not advanced coding language skills. Choosing whether or not to use interactivity that requires plug-ins is a critical decision in user experience design. If the plug-in doesn't come pre-installed with most browsers, there's a risk that the user will have neither the know how or the patience to install a plug-in just to access the content. If the function requires advanced coding language skills, it may be too costly in either time or money to code compared to the amount of enhancement the function will add to the user experience. There's also a risk that advanced interactivity may be incompatible with older browsers or hardware configurations. Publishing a function that doesn't work reliably is potentially worse for the user experience than making no attempt. It depends on the target audience if it's likely to be needed or worth any risks.
