Efficient Bimanual Symmetric 3D Manipulation for Markerless Hand-Tracking

In proceedings of Virtual Reality International Conference (VRIC), Apr. 2009
 

Abstract

Recently, stable markerless 6 DOF video based hand-tracking devices became available. These devices simultaneously track the positions and orientations of the user’s both hands in different postures with at least 25 frames per second. Such hand-tracking allows for using the human hands as natural input devices. However, the absence of physical buttons for performing click actions and state changes poses severe challenges in designing an efficient and easy to use 3D interface on top of such a device. In particular, for coupling and decoupling the object’s movements to the user’s hand (i.e. grabbing and releasing) a solution has to be found. In this paper, we introduce a novel technique for efficient two-handed grabbing and releasing objects and intuitively manipulating them in the virtual space. This technique is integrated in a novel 3D interface for virtual manipulations. A user experiment shows the superior applicability of this new technique.
