Patent ID: 7342649

Claim:
A handheld computer which is connectable to an optoelectronic distance measuring device ( 3 ) in an integrated manner so as to communicate bidirectionally therewith or which is connectable to the optoelectronic distance measuring device ( 3 ) via a data interface ( 26 ), comprising: computing means ( 7 ); an algorithm ( 8 ) executed by the computing means ( 7 ) and designed for interacting with the optoelectronic distance measuring device ( 3 ); input means ( 5 ) connectable to the computing means ( 7 ); and display means ( 6 ) suitable for marking and displaying a graphic object ( 4 ) generated by the computing means ( 7 ) using the algorithm ( 8 ) and inputs from the user through the input means ( 5 ), wherein the computing means ( 7 ) of the handheld computer ( 2 ) implements the algorithm ( 8 ) in a sequence that is repeated a number of times, to wait for a marking event ( 12 ) to occur in a marking step ( 10 ), which marking event ( 12 ) is initiated by the user by the input means ( 5 ) when marking the graphic object ( 4 ) displayed in the graphic representation ( 24 ) displayed by the display means ( 6 ), and to wait for a survey event ( 13 ) to occur in a survey step ( 11 ) which is close in time to the marking event ( 12 ), which survey event ( 13 ) is triggered by a survey result ( 15 ) measured by the user by means of the optoelectronic distance measuring device ( 3 ), whereupon the survey result ( 15 ) is associated with the marked graphic object ( 4 ) in a subsequent association step ( 14 ).
