Abstract: A system of active fiducial markers for pose calculation of head mounted displays is described in which information is exchanged among said markers for the purpose of synchronization. Fiducial patterns are made more easily identifiable by selective duty cycles of sub groups of synchronized emitters and means is described to propagate pose information among markers.

Abstract: In a head mounted virtual reality or augmented reality system, a fast but lower resolution second camera is added and used to quickly find an area of a visual field returned by a slower but higher resolution first camera, where that area is likely to contain the image of a marker for a head tracking system or a hand held device.
