As a college student, I was interested in design and content, but I didn't have a systematic understanding of UX/UI and simply thought that a pretty screen meant good design. Through this lecture, I learned that UX/UI is not just simple visual design, but a process of comprehensively designing user behavior, psychology, and flow. The appropriate real-world examples for each concept were explained in a way that was easy to understand, helping me get a feel for how UX/UI is applied in practice. Moving forward, I think I will study apps and websites more analytically by applying what I've learned!
