What is the primary focus of user interface (UI) design?

The primary focus of user interface (UI) design is to enhance the user experience through effective interface layout and design. UI design is all about how users interact with a product or application. This includes the arrangement of buttons, text, images, and other visual elements that users engage with. A well-thought-out UI allows for intuitive navigation, ensuring that users can accomplish their goals quickly and efficiently. It prioritizes functionality alongside aesthetic elements to create a seamless experience for the user.

UI design encompasses understanding user behaviors, preferences, and needs, which in turn guides how to present information and functions in a way that is logical and accessible. Therefore, the primary aim is not just to make things look good, but to facilitate ease of use and improve the overall interaction that users have with the interface.
