POINTING SYSTEMS FOR ADDRESSING OBJECTS

摘要

Systems are arranged to provide a user (521) information (533) which relates to objects of interest (525). A user may point a hand held device (522) 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 (12) containing preprogrammed information relating to objects. Information relating to objects determined as objects presently being addressed in thereafter presented at a user interface (532). Devices of these systems include a point reference (545), a direction reference (546), a position determining (26) support, attitude (29) determining support, a computer processor (23) and database, and a user interface (532). Methods of systems include the steps of addressing an object (161), determining position and attitude (161) searching a database (221), and presenting information to a user (237).
