Exploring the Effects of Group Interaction in Large Display Systems
Hao Jiang · International Journal of Performability Engineering · 2018
Large display systems have been successfully applied in the virtual reality domain because they can provide a full immersion sense through large visual space and high display resolution.However, most of the previous studies on the interaction method of those systems focused on single or double users.In this paper, we study the effects of integrating group interaction in such systems and we propose a framework called "Groupnect", which enables the unique experience of group interaction in a large display system.By using optical tracking and 3D gesture recognition technologies, our approach can automatically recognize gesture-based control signals for 20 users simultaneously and trigger corresponding real-time actions in a back-end system.Through a comparison experiment between standard interaction mode and group interaction mode, the results demonstrate that physical and mental participation of users could be promoted in group interaction mode.It has immense potential to design group interaction applications on entertainment, education and training areas.
