Learning objectives

The course introduces students to the fundamental theories and concepts of human-computer interaction (HCI), which is an interdisciplinary field that draws from cognitive psychology, computer science, and design. HCI aims to provide both theoretical understanding and hands-on experience in key aspects of human perception, cognition, and learning as they relate to interface design, implementation, and evaluation. Covered topics include interface design, usability evaluation, universal design, and multimodal interfaces (touch, vision, natural language, audio). Special emphasis will be placed on equipping students with foundational knowledge, methodologies, and tools necessary for designing, implementing, and evaluating computer systems capable of capturing, representing, and automatically analyzing user behavior. This encompasses various forms of non-verbal communication, including gestures, movements, facial expressions, and speech. Moreover, students will learn strategies for effectively interacting with users by providing multisensory feedback, utilizing elements such as images, sounds, and control of actuators.

At the end of the course, students will:
- Understand the rationale behind utilizing multimodal interactive systems for specific applications, comprehend the logical architectures defining the main components of such systems, grasp the design and development guidelines for multimodal interactive systems, and recognize the potential application areas for their successful deployment.
- Familiarize themselves with the key devices for capturing user behaviour data, comprehend their functionality, and discern appropriate usage scenarios.
- Acquire knowledge of essential techniques for representing and automatically analysing user behaviour, including those that process data from multiple sensor devices across various sensory channels.
-Demonstrate proficiency in designing and implementing major components of a multimodal interactive system using the development tools introduced in lectures and practical sessions throughout the course.
