It focuses on usability, accessibility, and aesthetics, aiming to provide users with a seamless and intuitive experience. Interface designers consider user needs, preferences, and behaviors to design interfaces that are efficient, easy to navigate, and visually appealing. This research area often involves user research, prototyping, and testing to ensure that interfaces meet user expectations and goals.
