Xsens teams up in a strong European consortium to develop a unique, markerless, solution for real-time 6DOF tracking for augmented and mixed reality applications. Per Slycke (CTO) of Xsens: "The MATRIS project aims to develop a unique, easy-to-use and robust technology for accurate 6DOF tracking of cameras in augmented and mixed reality applications. In technical terms, the system will track position, orientation, and focal length of a camera in real-time, using the camera images together with unobtrusive 6DOF inertial motion sensors mounted on the camera. This approach mimics the way a human orients himself, using the vestibular organ (in the ears) -which is essentially an inertial measurement unit, and the eyes- essentially comparable to a camera. The great thing about this approach is that the tracking system will not require any special infrastructure, or markers, to be installed."
