MovableBag: Exploring Asymmetric Interaction for Multi-user Exergame in Extended Reality

Abstract

Previous research shows that virtual reality (VR) exergames motivate users’ physical activity with immersion and enjoyment. However, it limits the movement for players to perform intense exercises in a small space with a complex tracking setup. In addition, asymmetric interaction of multi-user exergame in the same physical space is also lacking in the discussion in extended reality (XR). So, we present MovableBag, a substitutional robot that can be adapted to multi-user exergames with prop. It also serves as an agent to allow users from the physical world to interact with the VR user to become an XR application. Additionally, a preliminary study has been conducted, and a multi-user boxing exergame is designed to investigate the usage of the work. It also informs future design for more use cases in XR for asymmetric interaction between VR and non-VR users.
