User Interface (UI) refers to the means through which a user interacts with a device’s hardware or software. It encompasses the visual and auditory elements of a website or application, including buttons, icons, menus, and layout designs that guide user interactions.
UI in design for web applications or websites is a critical aspect of user experience, as it determines how intuitive and visually appealing the interaction is. Effective UI design aims to make the interface as user-friendly and efficient as possible, ensuring that users can easily navigate and accomplish their tasks. By focusing on aesthetics and functionality, UI design plays a pivotal role in the overall satisfaction and engagement of users with the technology.
