What is user interface design?

User interface (UI) design is the process designers use to build interfaces in software or computerized devices, focusing on looks or style . Designers aim to create interfaces which users find easy to use and pleasurable. UI design refers to graphical user interfaces and other forms—e.g., voice-controlled interfaces.

An application interface, or user interface, is the set of features an application provides so that a user may supply input to, and receive output from, the program . If you think about Microsoft Word, as an example, the application interface includes a central area for typing and adding feedback on your screen.

A mobile user interface (mobile UI) is the graphical and usually touch-sensitive display on a mobile device, such as a smartphone or tablet, that allows the user to interact with the device’s apps, features, content and functions.
