Human-Computer Interaction
A.Y. 2024/2025
Learning objectives
The course aims to provide students with theoretical, methodological, and practical instruments to achieve a knowledge and awareness of what it means to design (for) and evaluate interaction with interactive computational systems and to make the user experience rewarding and engaging, considering the main dimensions of usability (notably effectiveness, efficiency and satisfaction). Students will have to document a project of realistic complexity for the realization of an application (mobile or desktop) or online service, of which they will know how to evaluate different dimensions, including the technical feasibility and potentiality, or alternatively perform a comparative evaluation of existing state-of-the-art systems and services.
Expected learning outcomes
By the end of the course, students will be able to:
1. Demonstrate a comprehensive understanding of the impact of design sciences and the paradigms of human-computer interaction on the design and evaluation of interactive intelligent systems for heterogeneous domains and environments.
2. Identify and explain the fundamental principles of user-centered design, usability, and user experience evaluation, along with human-AI interaction protocols and paradigms, recognizing their significance in creating effective and engaging interactive systems from an ethical, responsible, and human-centered perspective.
3. Apply user-centered design methodologies and human-AI interaction protocols to design and evaluate interactive systems.
4. Assess the ethical and social implications of AI systems, ensuring fair, accountable, transparent, and explainable AI.
5. Design advanced human-system interfaces, including sensing technologies, biometric systems, and computer vision for human-machine interaction.

Prerequisites for admission
There are no formal prerequisites for this course. Basic concepts of human-computer interaction will be outlined at the beginning of the course. However, students are encouraged to deepen their input knowledge, if any, by following the recommended readings in the coursework.
Teaching methods
The course will be delivered through a combination of lectures and practical classes. Teaching methods include:
· Erogative - Lectures: To cover foundational concepts and theoretical aspects.
· Interactive - Guided practical work: Group activities, including project work, where students apply explained theories, interaction guidelines, and collaboration protocols to real-world case studies.
The teaching activity will be delivered in person, unless otherwise indicated, due to national and/or University directives due to the prolonged COVID-19 emergency. In that case, face-to-face classes and lab lectures will be primarily synchronous (with strongly promoted participation) via WebEx or an equivalent platform as indicated on the course website.

Assessment methods and Criteria
The final exam is held in mixed form, i.e., partially written and oral, as well as individual but also relating to work presented as members of a group; some questions may be closed-ended and to be answered with one's smartphone or PC. The project may be either about defining a human-centered research protocol (human-centered) of a user study (user-study) or the preliminary feasibility study and rapid prototyping of an IT service or application or the usability evaluation of a state-of-the-art service/system; lecturers will give precise specifications (brief) during the course. Students are expected to hand in the entire project documentation in advance, the presentation of which to the lecturer (as the client/customer) may be a specific component if requested.
Final evaluation will take into account the following criteria:
- Correctness: Appropriate use of design and evaluation methodologies.
- Completeness: Completeness of the project, including all required sections and analyses.
- Accuracy: Accuracy in documenting the design and interaction processes.
- Correspondence: Alignment of project results with the given specifications, initial objectives and assigned tasks.
The final grade will be a weighted sum of the scores from each evaluation component. The total score will be converted to a 30-point scale, with each component contributing.
