The main focus of user interface (UI) design is to create intuitive and visually appealing interfaces that enhance user interaction with digital products. UI designers aim to facilitate a seamless experience by prioritizing aspects such as usability, accessibility, and aesthetic appeal. This involves making informed choices about layout, color schemes, typography, and interactive elements to guide users toward their goals effectively. The success of UI design directly impacts user satisfaction and retention, making it a crucial aspect of product development in both web applications and mobile apps.
