Themen der Lehrveranstaltung
---------- LECTURES ---------- During the lectures, the following topics will be covered. 1. Theoretical Foundations of Human-Centred Interaction Design * Introduction to human-centred interaction design: theoretical and process-oriented approaches * Mental models and conceptual models * Human factors relevant to interaction, e.g. visual perception * Introduction to usability and user experience, and their key dimensions * Overview of accessibility and inclusion as design principles 2. Theories and Models for Interaction Analysis and Design * Introduction to interaction analysis: people, goals and context of use * User analysis and reference models, e.g. PACT * Context analysis and reference models, e.g. task analysis 3. Interaction Design * Principles and major patterns for the design of interactive interfaces * Definition of interaction and interface requirements according to recent models, e.g. DIRA * Conceptual representations of interaction with interfaces, e.g. use cases, user flows, wireflows and state diagrams 4. Introduction to Interaction Evaluation Approaches, Methods and Metrics * Comparison between analytical and empirical evaluation * Analytical evaluation: objectives, participants, tools and examples (e.g. walkthroughs) * Introduction to empirical usability evaluation: objectives, participants and tools (e.g. usability testing, think-aloud protocols), satisfaction questionnaires (e.g. SUS), and performance metrics (e.g. success rate for formative evaluations and confidence interval calculation using the adjusted Wald method) ---------- LABORATORY SESSIONS ---------- Durante labs, the acquired knowledge will be applied to case studies assigned by the teacher yearly. 5. Analysis of Case Studies and Development of Conceptual Models * Analysis of case studies * Development of conceptual models 6. Prototyping and Evaluation * Low- and medium-fidelity prototyping, e.g. storyboarding, sketching and wireframing with Balsamiq * High-fidelity prototyping, e.g. creation of wireflows with Figma * Usability and user experience evaluation of design solutions

Bildungsziele und erwartete Lernergebnisse (zus. Informationen)
By the end of the course, students will be able to analyse human-computer interaction problems by considering users, activities and context of use; apply models and techniques for the design of interactive interfaces and systems; represent and communicate design solutions through appropriate analysis and design artefacts; develop interactive prototypes at different levels of fidelity; and critically evaluate the quality of interaction using analytical evaluation methods and basic empirical approaches.

Art der Prüfung
Assessment is based on a written examination designed to evaluate: (1) knowledge and understanding of the theoretical concepts covered in the course; and (2) the ability to apply these concepts to the analysis, design, and evaluation of interactive systems. The examination includes: (1) questions and exercises relating to the theoretical content of the module; and (2) practical exercises aligned with the laboratory activities, covering the analysis, modelling, design, prototyping, and evaluation of interaction. Students who attend at least 70% of the overall teaching activities may undertake a small project as part of the laboratory component, developed and presented during laboratory hours. The project may contribute up to a maximum of 3 bonus marks towards the final grade. The number of bonus marks awarded depends on the quality of the project and will be recognised only if a minimum mark of 18/30 is achieved in the written examination.

Bewertungskriterien
Assessment is designed to verify the acquisition of theoretical knowledge relating to human-computer interaction and the ability to apply such knowledge to the analysis, design, prototyping and evaluation of interactive interfaces. Particular attention is given to the ability to select, use and apply appropriate models, to produce coherent artefacts (for analysis, design, prototyping and evaluation), and to provide a critical justification for the choices made.
