Short description
The task of managing and accessing large information spaces is a problem in large scale cognition. Emerging technologies for 3D visualization and interactive animation offer potential solutions to this problem, especially when the structure of the information can be visualized. We describe one of these Information Visualization techniques, called the Cone Tree, which is used for visualizing hierarchical information structures. The hierarchy is presented in 3D to maximize effective use of available screen space and enable visualization of the whole structure. Interactive animation is used to shift some of the user's cognitive load to the human perceptual system.
Suitable Datatypes
Suitable Datatypes are hierarchical information structures.
Figures
Each tree node is the apex of a cone. The children of each node are drawn around the base of its associated cone.
Examples and use cases
Cat-a-Cone (Hearst & Karadi 1997)
The Cat-a-Cone interface. Shown are the results of a search on category labels Mastectomy and Radiation Therapy in conjunction with the text word ``lumpectomy on a breast cancer subset of the MEDLINE collection. A ConeTree displays category labels and a WebBook shows retrieval results. The lefthand page shows the title and the category labels associated with the document. The righthand page shows the abstract associated with the document. Books that are the results of previous searches are stored in the workspace on the bookshelf, thus acting as a memory aid.
Example 1: A UNIX file-system displayed as cone-tree
Example 2: Layout of a simple Cone Tree
