UX UI design refers to the combined disciplines of user experience (UX) and user interface (UI) design, both crucial in creating optimal interactions between users and digital products. UX design focuses on the overall feel of the experience, aimed at maximizing user satisfaction by improving the usability, accessibility, and efficiency of user interactions. UI design, on the other hand, concentrates on the look and layout of the product, ensuring that the interface is visually appealing and logically organized.
