Abstract
This paper describes a hybrid optical-inertial tracking
technology for fully-immersive projective displays. In or-
der to track the operator, the operator wears a 3DOF com-
mercial inertial tracking system coupled with a set of laser
diodes arranged in a known configuration. The projec-
tion of this laser constellation on the display walls are
tracked visually to compute the 6DOF absolute head pose
of the user. The absolute pose is combined with the iner-
tial tracker data using an extended Kalman filter to main-
tain a robust estimate of position and orientation. This
paper describes the basic tracking system including the
hardware and software infrastructure.
