Abstract [en]

The purpose of this study is to evaluate and give suggestions for interaction improvements to a user interface in a Personal Video Recorder. The study will focus on user learnability, user satisfaction, usability problems from the user interaction with the product and to make a set of interaction improvements. The participants performed a set of predefined tasks involving the recorder functionality and channel lists. The study involved three trials with seven tasks in each trial.


The study showed that the time difference for Learnability – Time-on-Task between all trials were statistical significant for the user interface. The study also revealed a set of usability problems that were classified into different severity ratings. The study also showed that the participants were partly satisfied with the user interface.
