Management and control system for coordinate

Abstract

Abstract PURPOSE:To precisely input coordinates by displaying both of a coordinate address marker and a display address marker on a display screen of a graphic display device. CONSTITUTION:When a detection part position is moved from a point (a) to a point (b) on a coordinate input surface 13, a coordinate input device address marker ''+'' is also moved from a point a' to a point b' on a display screen 12. Since a display address marker ''x'' is not moved by the simple movement of the detection part position, the display of the marker ''+'' can be moved to a required position on the basis of the marker ''x''. If an input switch in a coordinate detection part is depressed after deciding the coordinate input device by said procedure, the coordinates are inputted to a host processing device, a display address pointer is updated by the inputted coordinate value and the display address marker ''x'' is moved to the position of the coordinate input device address marker ''+'' at the input of coordinates.
