Usability Engineering II - User Interface Evaluation


Prof. Dr. Harald Reiterer


Tobias Limbach, Jens Gerken







Thursday 10:00-12:00 (L)
Thursday 16:00-18:00 (E)


The course Human-Computer Interaction (HCI) lays the necessary foundations for this course. The aim of this course is to deepen the topic HC3 of the HCI course:

  • HC3 Human-Centered Software Evaluation: overview about the main usability evaluation methods and techniques (e.g. observing users, asking users, asking experts, user testing, modeling users’ task performance).

Evaluation is the process of systematically collecting data that informs designer about what it is like for a particular user group to use an interactive product for a particular task in a certain type of environment. Evaluation is a core activity in Usability Engineering and a lot of different well-established evaluation methods are available now (e.g. heuristic or expert evaluation, usability testing in a lab, field studies, questionnaires). After a comprehensive presentation of a variety of evaluation methods and techniques, the students will evaluate different interactive products using different evaluation approaches. One important part of this course is, that the students can make use of a usability lab to gain their own experience how to conduct usability testing. Basics about experimental design will also be part of this course (e.g. how to formulate hypothesis, what are dependent and independent variables, how to set up experimental conditions, allocation of participants).






Assignment (Hausarbeit) must be finished in the last week of the semester
