ABSTRACT

During the Corona Virus (COVID-19) pandemic, many digital solutions for mobile devices (e.g. apps) were showcased to provide additional resources supporting pandemic control. One of the most popular and promising solutions are contact tracing apps (i.e. identifying people who may have been in contact with someone infected with COVID-19). However, as a prerequisite for effective application, these applications are highly dependent on their use by a large number of the population. Therefore, it is important that these applications provide great ease of use for everyone. So we conducted an exploratory study to find out more about the usability of the German COVID-19 contact tracing application Corona-Warn-App (CWA). Specifically, N = 15 participants rated the CWA, using a combined retrospective eye tracking and thinking aloud approach. The results indicate, on the one hand, that the CWA leaves a promising impression for pandemic control, as essential functions are easily recognized. However, on the other hand, issues have been revealed (e.g. privacy policy) that could be addressed more properly in future updates.
