Benutzererfahrung mit Alexa, Siri und Google Assistant bei der Steuerung von Musik - Vergleich von vier Fragebögen
Abstract
We evaluate user experience (UX) when users play and control music with three smart speakers: Amazons Alexa Echo, Google Home and Apple's Siri on a HomePod. For measuring UX we use five established UX and usability metrics (AttrakDiff, SASSI, SUISQ-R, SUS). We investigated the sensitivity of these five questionnaires in two ways: firstly we compared the UX reported for each of the speakers, secondly we compared the UX of completing easy single tasks and more difficult multi tasks with these speakers. We find that the investigated questionnaires are sufficiently sensitive to show significant differences in UX for these easy and difficult tasks. In addition, we find some significant UX differences between the tested speakers. Specifically, all tested questionnaires, except the SUS, show a significant difference in UX between Siri and Alexa, with Siri being perceived as more user friendly for controlling music. We discuss implications of our work for researchers and practitioners.
