Human-computer interaction

The interdisciplinary study of the design, evaluation, and use of interactive computing systems by humans, drawing on computer science, psychology, design, and social science. HCI research encompasses how people use technology, how interfaces should be designed for usability and accessibility, and how emerging technologies (VR, AI, tangible computing) create new interaction possibilities. Accessibility is a core concern within HCI, as the field seeks to ensure that interactive systems are usable by people with the widest range of abilities, contexts, and preferences.
