Abstract: An apparatus and method is disclosed for enabling accurate registration of virtual information upon real objects in selected environments from the perspective of a moveable observation platform having a position and an orientation within an observation space positioned within the environment, the position and orientation defining the registration of the virtual information within the observation space within the environment, which may comprise: a plurality of at least three tracking fiducials selectively each respectively located in fixed predetermined locations in the observation space; the observation platform including a position sensor apparatus adapted to sense an estimated position of the observation platform in the observation space and a heading sensor apparatus adapted to sense an estimated heading of the observation platform within the observation space; the observation platform further including a wide view fiducial detection apparatus mounted on the observation platform and adapted to detect the r

Abstract: An apparatus and method provides application specific multidimensional information to an application running on a user computing device from a plurality of member documents electronically extracted from a library of electronically searchable documents. An information extractor is adapted to extract occurrences of prospective representations of dimensions of application specific multidimensional information and occurrences of non-application specific multidimensional information from the member documents. Also, an encoder is adapted to encode the occurrences of prospective dimensions of application specific and non-application specific multidimensional information contained in member documents. A member document identifier determines document formatting and decides whether to proceed with further processing. An information verification unit optionally verifies the extraction of application specific multidimensional information from the member documents.
