Guest researcher Kai Holzwessig presented a lecture about the measurement of User Experiences (UX)

During his lecture on Thursday 8th September for students studying Usability testing, prototyping and evaluation, Kai covered several topics. He started out by discussing the nature of User Experience (UX), and the goals of web designers when working with UX.

So, how can an experience be measured, in this case a user experience? Kai explained during the lecture that there are several standardised questionnaires for measuring user experience, and he gave a couple of examples. The Software Usability Scale (SUS) and Questionnaire for User Interaction Satisfaction (QUIS) are aimed at usage after a study is completed, i.e. after a complete study or set of tests is completed. There are also questionnaires designed to be used after a specific task is undertaken, i.e. after each test scenario is carried out. There include the Single Ease Question (SEQ) and Subjective Mental Effort Question (SMEQ).
Kai also presented the tool AttrakDiff, an instrument that employs the semantic differential to assess UX qualities. Originally the AttrakDiff was developed by Hassenzahl et al. In AttrakDiff the user experience is split into four dimensions: Pragmatic quality (PQ), Hedonic quality – identity (HQ-I), Hedonic quality – stimulation (HQ-S) and Attractiveness (ATT). Kai had prepared a dataset so that those present could try out the tool in order to assess the UX for the websites for Apple and Lenovo.
Kai’s experience in measuring User Experience (UX) was welcomed and we look forward to further exchanges of ideas in the future.
