We investigate how spatial layout in public environments like workplaces, fairs, or conferences inﬂuences a user’s VR experience. In particular, we compare environments in which an HMD user is (a) surrounded by other people, (b) physically separated by a barrier, or (c) in a separate room. In contrast to lab environments, users in public environments are affected by physical threats (for example, other people in the space running into them) but also cognitive threats (for example. not knowing, what happens in the real world), as known from research on proxemics or social facilitation. We contribute an extensive discussion of the factors inﬂuencing a user’s VR experience in public. Based on this we conducted a between subject design user study (N=58) to understand the differences between the three environments. As a result, we present implications regarding (1) spatial layout, (2) behavior of the VR system operator, and (3) the VR experience that helps both HCI researchers as well as practitioners to enhance users’ VR experience in public environments.
