Design dimensions are derived from a focus group with experts and a literature review. The space supports the design of indicators which aim to facilitate users' decision making, awareness and understanding, as well as increase transparency of behavioural biometrics systems. We conclude with a set of example designs and discuss further extensions, future research questions and study ideas.}, note = {}, institution = {Universität der Bundeswehr München, Fakultät für Informatik, INF 5 - Institut für Anwendungssicherheit, Professur: Alt, Florian}, }
