Systems are arranged to provide a user information which relates to objects
of interest. A user may point a hand held device toward an object to address it.
The device determines which objects are being addressed by making position and
attitude measurements and further a reference and search of a database containing
preprogrammed information relating to objects. Information relating to objects
determined as objects presently being addressed is thereafter presented at a user
interface. Devices of these systems include a point reference, a direction reference,
a position determining support, attitude determining support, a computer processor
and database, and a user interface. Methods of systems include the steps of addressing
an object, determining position and attitude, searching a database, and presenting
information to a user.
