After successful completion of the course, students are able to apply basic knowledge about "user experience" and interaction design. Students learn the psychological constructs relevant for interaction design (such as user acceptance, trust, user experience, etc.), as well as scientific methods for the systematic analysis of existing and the development of novel user interfaces, taking into account the respective phases of the human-centered design process.

This course provides methodological knowledge for the targeted evaluation of human-machine interfaces, idea and prototype generation in different product development phases, as well as basic knowledge about human factors.

Basics:

• Definitions and acquisition of key constructs
• Human-centered design process
• Scientific evaluation of human-machine interfaces
• Human-in-the-loop systems (input/output, decision making, etc.)
• Fundamentals of human perception
• "Human factors" basics
• Basic knowledge of input and output devices
• Design principles (colors, shapes, etc.)
• Human and behavioral models (Fitt's law, GOMS, KLM, etc.)
• Task and context analysis

Practice

• Structured application of the human-centered design process
• Design and implementation of user studies
• Requirements elicitation
• Idea generation and prototyping (sketching, wireframes, video-, soft- and hardware prototyping)
• Evaluation methods (interviews, questionnaires, lab and field experiments)

Interface & Interaction Design teaches knowledge and methods for the design of human-machine interfaces. The course combines knowledge relevant to the "Human-Centered Design Process" from different domains, such as computer science, ergonomics, and psychology.

 The assessment takes place via a semester project. Project groups (3 students per group) must implement 5 tasks based on the "human-centered design process". These include tasks relevant to interaction design (analysis, idea generation, design, implementation, and evaluation). Students have to solve the tasks, document them and present their results. The presentation of the final assignment will be a short video (3-5 minutes). The final grade will be determined from the points of each assignment (10 points per assignment) along with the final presentation (50 points).
