simultaneous 4 gestures 6 dof real-time two-hand tracking without any markers
In this paper we present a novel computer vision based handtracking method, which is capable of simultaneously tracking 6+4 degrees of freedom (DOFs) of each human hand in real-time (25 frames per second) with the help of 3 (or more) off-the-shelf consumer cameras. '6+4 DOF' means that the system can track the global pose (6 continuous parameters for translation and rotation) of 4 different gestures. Different studies discovered the need for two-handed interaction to enable an intuitive 3D Human-Computer-Interaction. Previously, using both hands as at least 6 DOF input devices involved the use of either datagloves or markers. Applying our two-hand-tracking we evaluated the use of both hands as input devices for two applications: fly-through exploration of a virtual world and a mesh editing application.
