Polyvalent display framework to control virtual navigations by 6DOF tracking

Many applications using Virtual Reality (VR) require free hand navigation control. This forbids the use of devices such as Joystick, 3D mouse, ... That is generally because hand-based gesture interaction must be dedicated to specific tasks: sculpting or grasping the objects, which compose a virtual scene. With this aim, we present a polyvalent display approach, which allows the system to determine the desired focus and the moving intention of the user for virtual navigations. After we point out the limits of the classical solutions used to control virtual navigations, we describe the conceptual and mathematical implementation of our approach. Some of our considerations depend on physiological and ergonomic constraints. We conclude on the first applications of our fully head tracking navigation controller.
