Hierarchical Navigation device

The invention relates to a hierarchical Navigation device. Hierarchical structures are visualized and navigated using an orbital model. Sibling nodes are orbitally displayed in a generally circular arrangement along an orbital path. Choosing one of the orbitally displayed nodes opens it, moving down in the hierarchy. Nodes which were not chosen are undisplayed, and child node(s) of the chosen node are orbitally displayed. Node movements may be animated. A history displays recently chosen nodes. Choosing a parent node of the orbiting nodes undisplays the child nodes, and the parent node and its siblings are orbitally displayed, thereby moving up in the hierarchy. A user may select nodes from different parts of the hierarchy by moving them into a selection tray. Selected nodes can then be subjected to a specified batch operation. Controls are available for sorting nodes and/or for altering node appearance in the display. 本发明涉及分层导航设备。使用轨道模型，可视化和导航分层结构。沿着轨迹以般圆形的排列以轨道方式显示兄弟节点。选取以轨道方式显示的节点中的个，会打开它，并在分层结构中向下移动。取消显示没
