Duality Board: An Asymmetric Remote Gaming Platform with Mobile Robots and the Digital Twins

Due to lifestyle changes caused by COVID-19 and other factors, the importance of gaming platforms that allow users to play together with distant friends and family members is increasing. In general, it is difficult for users with widely different gaming skills to play together. Therefore, game designers need to take asymmetry into account, such as providing different roles and different operation interfaces for each user. In this study, we propose a foundation for an asymmetric tele-gaming platform using mobile robots and their digital twins. Then, we conducted an experiment to evaluate the usability of this platform. As a result, we found that the visual size of the digital twin may affect the usability. Based on these results, we propose a model of the relationship between the size of the digital twin and the usabilityperceived by the user.
