User interface (UI) design comprises a significant portion of software development, encompassing various types (GUI, VUI, multi-modal) and adhering to key principles like user familiarity, consistency, and recoverability to ensure efficient and intuitive interaction. Effective UI design considers technical and perceived efficiency, user diversity, and state visualization.
