An Asymmetric Bimanual Gestural Interface for Immersive Virtual Environments

In this paper, a 3D bimanual gestural interface using data gloves is presented. We build upon past contributions on gestural interfaces and bimanual interactions to create an efficient and intuitive gestural interface that can be used in a wide variety of immersive virtual environments. Based on real world bimanual interactions, the proposed interface uses the hands in an asymmetric style, with the left hand providing the mode of interaction and the right hand acting on a finer level of detail. To validate the efficiency of this interface design, a comparative study between the proposed two-handed interface and a one-handed variant was conducted on a group of right-handed users. The results of the experiment support the bimanual interface as more efficient than the unimanual one. It is expected that this interface and the conclusions drawn from the experiments will be useful as a guide for efficient design of future bimanual gestural interfaces.
