DuplicateSpace: Enhancing Operability of Virtual 3D Objects by Asymmetric Bimanual Interaction

Abstract

DuplicateSpace is a 3D interaction platform that enables direct manipulation by two-handed interaction in a virtual environment. Our platform aims to enhance the operational feasibility and realistic feeling of the virtual world by allowing operability of virtual objects through real-world metaphors. On this platform, we apply asymmetric bimanual interaction, which combines a bare hand and a hand-held device, to provide direct manipulation by synchronizing a virtual space and a physical space. We investigate the role of the two handed modalities and suggest a tangible interaction design to enhance the operability of virtual 3D objects. Through an informal user study under DuplicateSpace, we estimate the enhancement of familiarity to the virtual world.
