A compact hand-held viewing apparatus that automatically determines the three-dimensional direction in which it is pointing and automatically presents information to the user related to features which are visible in the field of view of the apparatus in that three-dimensional direction. Any given em ...

Michael Lemp III, Michael Hatalski: Viewing and display apparatus position determination algorithms. Yamcon, K David Crockett Esq, Crockett & Crockett, March 14, 2006: US07010862 (4 worldwide citation)

Celestial object location devices with sensor arrays of having less that one sensor for each of three orthogonal components of gravity and magnetic field vectors. The accuracy of position sensing is enhanced by estimating “missing” sensor input based on input from two orthogonal sensors provided, or ...
