Information relating to objects being addressed can then be presented at a user interface. A device of the system may 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.
