Given the difficulties of studying the shoulder surfing resistance of authentication systems in a live setting, researchers often ask study participants to shoulder surf authentications by watching two-dimensional (2D) video recordings of a user authenticating. How-ever, these video recordings do not provide participants with a realistic shoulder surfing experience, creating uncertainty in the value and validity of lab-based shoulder surfing experiments. In this work, we exploit the unique characteristics of virtual reality (VR) and study the use of non-immersive/immersive VR recordings for shoulder surfing research. We conducted a user study (N=18) to explore the strengths and weaknesses of such a VR-based shoulder surfing research approach. Our results suggest that immersive VR observations result in a more realistic shoulder surfing experience, in a significantly higher sense of being part of the authentication environment, in a greater feeling of spatial presence, and in a higher level of involvement than 2D video observations without impacting participants’ observation performance. This suggests that studying shoulder surfing in VR is advantageous in many ways compared to currently used approaches, e.g., participants can freely choose their observation angle rather than being limited to a fixed observation angle as done in current methods. We discuss the strengths and weaknesses of using VR for shoulder surfing research and conclude with four recommendations to help researchers decide when (and when not) to employ VR for shoulder surfing research in the authentication research domain. |
