The aim of this course is to provide a comprehensive overview of the theoretical models underlying Human–Computer Interaction (HCI), as well as the technologies, methods, and tools used in the design and development of interactive software systems. The course begins with an introduction to the field of Human–Computer Interaction, followed by the study of the human user as part of a computational system. It examines cognitive models related to perception, mental representation, attention, memory, knowledge organization, and mental models, considering both individual and collaborative contexts.

The course further explores interaction technologies, including input and output devices, interaction styles, direct manipulation interfaces, computer-supported cooperative work (CSCW) systems, virtual reality, and assistive technologies for people with disabilities.

It also covers the methodologies used in the design of interactive systems, with particular emphasis on human-centered design, usability requirements, task analysis, GOMS models, dialogue description methods, user interface design, and the usability and accessibility of web applications.

Finally, the course presents methods for evaluating interactive systems and introduces the principles of Collaboration Technology, including synchronous and asynchronous collaborative applications, as well as techniques for evaluating the usability of collaborative systems.
