User experience (UX) design involves studying how people interact with computers and designing interfaces that provide good usability, accessibility, and pleasure. It draws from fields like human-computer interaction, behavioral science, and design. UX design uses techniques like user research, prototyping, and testing to understand users' needs and create products and services that meet business goals. The user-centered design (UCD) process involves researching users, developing concepts based on insights, and designing interfaces and features. UX design aims to create solutions that are easy and satisfying to use.
