A Platform for Collecting User Behaviour Data during Social VR Experiments Using Mozilla Hubs

In recent years, a large variety of online communication tools have Social VR, data collection, data visualisation, plugin, Mozilla Hubs emerged, including social Virtual Reality (VR) platforms for interacting in a virtual world with participants being represented as virtual avatars. Given their popularity, an active area of research focuses on improving the user experience in these virtual experiences. To enable experimentation at large scale on online platforms, it is however essential to collect behavioural data (e.g. movements and audio information). In this work, we present a toolchain that enables the running of experiments using a modified version of the social VR platform Mozilla Hubs. Specifically, our toolkit enables collection and tracking or user positions and movements at a central location, enabling fine-grained analysis of user behaviour during a social VR experience. The proposed tool is available at https://github.com/cwi-dis/mozillahubs- datalogger
