This course introduces the fundamental concepts and methodologies of Human-Computer Interaction (HCI). It examines the principles of interactive system design, usability evaluation methods, and user interface development techniques. Students will gain knowledge in gathering user requirements, developing prototypes, and design based on standards. Through exercises and a project, students will become familiar with modern information visualization techniques, the principles of universal design, and methods of interacting with advanced systems. The course combines theoretical foundations with practical application to real-world problems.
