<p>A display managing system, method and article of manufacture displays icons, tags and leader lines based on tracking information that includes position information of a plurality of objects; determines if a tag or leader line conflicts with repositioned icons; and relocates the conflicting tag or leader line to prevent a tag or leader line from overlapping and thereby obscuring the icon. Furthermore, the tags and leader lines associated with the repositioned tags are, themselves, repositioned. If these repositioned tags and leader lines conflict with an existing icon, tag or leader line, then the conflicting tag and/or leader line are moved to unoccupied display grid coordinates or a tag location is time-shared between two conflicting tags. Leader line stretching may also be used to prevent tags from jumping around as the icon is moved. An organized data base, which may be in the form of x-y trees, is employed to encode the positions of the display elements to permit efficient searches to locate tags, leader lines and icons and to resolve conflicts therebetween.</p> |
