What is user interface (UI) design primarily focused on?

User interface (UI) design is primarily focused on the interaction between users and the visual elements of a product. This discipline is centered around making interfaces that are not only aesthetically pleasing but also functional and easy to navigate. The goal of UI design is to ensure that users can understand how to use a product and achieve their goals through intuitive interaction with buttons, icons, menus, and other visual elements.

In UI design, emphasis is placed on how these visual elements come together to create an effective user experience. This includes considerations of layout, color schemes, typography, and overall visual hierarchy to guide users naturally through the interface. When UI is done effectively, it enhances user satisfaction and makes it easier for users to perform tasks within the application or platform. This focus on user interaction is what distinguishes UI design from other areas such as backend development, marketing, or content creation, which aim to address different aspects of a product’s lifecycle and strategy.
