The technological trend that focuses on enhancing user experience through user interface (UI) design is generally referred to as user experience design (UX). Effective UX design prioritizes usability, accessibility, and aesthetics to create intuitive and enjoyable interactions for users. This trend emphasizes understanding user behavior and integrating feedback into design processes to iterate on solutions. By focusing on customer needs and preferences, companies can develop products that not only meet functional requirements but also create positive emotional engagement, ultimately leading to increased satisfaction and loyalty.
