This course provides theoretical grounding, practical knowledge, and hands on experience of key skills and competences needed to shape computing systems for the 21st century. Human-Computer Interaction (HCI) is a distinctive branch of computer science dedicated to understanding the relationship between people and computers, and to enabling systems designers and software engineers to develop computing applications that better respond to the needs of customers, clients and end-users. Related terms include human-centred design, interactive systems design, user experience design, user interface design, and usability engineering. HCI is a key area of computing, promoted globally by the Association of Computing Machinery (ACM) and nationally by the British Computer Society (BCS). The course addresses core areas of the ACM SIGCHI Curricula for Human-Computer Interaction and is intended for students with diverse disciplinary backgrounds and experiences, including computer science, engineering, natural science, social science, and art and design. The MSc HCI is also good starting point for students who wish to study for a PhD in Human-Computer Interaction and the associated area of Computer Supported Collaborative Work (CSCW).
