User Interface (UI) Design is the process of designing the visual layout and interactive elements of a software application or website. It’s where aesthetics meet functionality. UI Design encompasses the selection of colors, button shapes, typography, animations, graphics, and all the aspects that contribute to the design of an interface. The aim is to create interfaces that are easy and pleasant to use, guiding users intuitively through their tasks. UI Design is closely tied to User Experience (UX) Design, although UX is broader and covers user research, content, and how users interact with the service as a whole.
A well-designed UI can make an application easy to understand and use, which improves its usability and the user satisfaction that comes from interacting with the product. UI Design is not just about creating a pretty interface; it’s about creating an interface that is harmonious, consistent, and streamlined, where each visual and interactive element has a purpose.
