The acronym UX stands for User Experience, which refers to the overall experience a user has when interacting with a product or service, particularly in software and web design. It encompasses aspects such as usability, accessibility, and visual design. A positive UX ensures that users find the product intuitive and enjoyable, leading to higher satisfaction and engagement rates. UX design involves research, prototyping, and iterative testing to understand user needs and behaviors, ultimately improving the effectiveness of user interfaces.
