Argomenti dell'insegnamento
The Human-Computer Interaction course explores the principles, methods, and tools essential for designing effective and user-friendly interactive systems. Students will learn foundational methods and frameworks, including User-Centred Design and PACT analysis (People, Activities, Contexts, Technologies), to understand the interaction between users and systems. Emphasis is placed on establishing quality metrics and applying design principles to create efficient graphical user interfaces (GUIs) using standard WIMP elements (Windows, Icons, Menus, Pointers), common design patterns, and attention to visual aesthetics and multimedia interaction. The course also covers the human-information processor model, covering essential cognitive aspects such as visual attention, perception, and memory, which directly influence interface usability. Finally, students will engage in evaluation techniques, learning how to identify user requirements, conduct formative and summative evaluations, and apply heuristic evaluations to iteratively improve design quality and user satisfaction.

Modalità di insegnamento
Service Learning with a mix of frontal lectures, hands-on activities, invited presentations, students’ active engagement.

Obiettivi formativi e risultati di apprendimento (ulteriori info.)
The course belongs to the type “caratterizzanti – discipline informatiche. The course is designed to give students first-hand experience of the design process of graphical interfaces. It follows the basic steps of requirements elicitation, design and evaluation. During the semester, students will be provided with a general overview of research in User-Centered Design of graphical interfaces. In parallel, they will work on an interaction design project, from ideation to mid fidelity prototype of a Graphical User Interface for a computing system. After successful attendance and engagement with the key study, the students are expected to acquire substantial professional skills and knowledge to move from conceptual design to a medium fidelity prototype. Non attending students will cover the same scientific content and will be given a set of structured exercises to support the individual elaboration of professional skills.

Modalità d'esame
Student performance in the Human-Computer Interaction course will be evaluated through a medium-fidelity prototype and project report and an oral examination. The prototype and project report will assess the ability to work collaboratively in a multidisciplinary team and coordinate tasks effectively (D4.3, D4.5), as well as creativity, critical thinking, and the capacity to summarize content clearly and originally (D4.2). Methodological rigor will also be evaluated, reflecting students' solid understanding of core and applied areas of computer science (D1.1). The oral examination will focus on clarity of responses, mastery of technical language, and the ability to summarize, evaluate, and connect different topics, demonstrating the ability to present complex information within a limited time to diverse audiences (D4.1). The written report will further assess methodological rigor and creativity, as well as the ability to summarize and critically evaluate topics while using precise, appropriate language (D4.2). Additionally, students will be evaluated on their ability to select and integrate documentation from a range of sources to support their work (D3.1) and to independently expand their knowledge through scientific and technical texts in English (D5.1).

Criteri di valutazione
The course is heavily project based and attendance is strongly recommended. Assessment for Attending students: Group project work • Written project report elaborated in groups (Max 10 page) to be delivered two weeks before the group sits the oral examination (50%). • Individual oral examination with presentation of the final prototype to evaluate the results of the project, test knowledge acquisition, and verify individual contribution to the group work (50%). Assessment for Non attending students: Individual examination • Course-work: Written project report elaborated in groups (Max 10 page) to be delivered two weeks before the group sits the oral examination (50%). • Individual oral examination with presentation of the final prototype to evaluate the results of the project, test knowledge acquisition, and verify individual contribution to the group work (50%).
