Inventions on Tree Navigators used in Graphical User Interface
This work is incremental, as it analyzes existing patents to identify solutions for improving tree navigators in GUIs, which could benefit software developers and users dealing with complex data hierarchies.
The paper reviews five inventions from US patents that address challenges in tree navigators for graphical user interfaces, aiming to improve efficiency and user experience when handling large hierarchical data structures.
A tree view or tree navigator is used to display hierarchical data organized in the form of a tree. In a tree structure there are parent and child nodes. The child nodes may further have descendants to n levels. There are many methods to make the navigation easy. Some of these are expanding and collapsing branches, splitting the tree, displaying a parent node in a separate tree, zooming branches, scrolling in various directions etc. It is still a difficult exercise to handle large trees efficiently. The effort still continues to manage large number of nodes with faster speed, greater control, user friendliness and aesthetics. This article illustrates five inventions on tree navigators selected from US patent database. Each of them tries to solve various problems relating to the tree navigator in different ways. Each invention is also analyzed from a TRIZ perspective.
