Abstract
A method of navigating a tree structure in a user interface is provided. A node set is displayed on the user interface, and includes a central node representing a parent node and child nodes arranged around it. Movement and/or position of a pointer is tracked. As the pointer is moved towards a child node, grandchild nodes are rendered and enlarged within the target child node until they fill the area of the target child node. At the same time, the area of the target child node around the central node relative to the other child nodes is enlarged. Once the pointer has crossed a first selection threshold at a threshold point, the grandchild nodes have completely filled the area of the target child node, and the central node is surrounded by the grandchild nodes so as to represent the target child node. In this manner, a tree structure may be continuously navigated through movement of the pointer.
