An intuitive, immersive, movement-based interface and system provides for navigating through large collections of multidimensional information. The interface allows users to navigate through large document collections by maintaining a constant density of visual information presented on a display device to the user at any given moment of time. The document collection is organized in an immersive information space, containing various levels of topics and related documents. At each level within the immersive information space contextual information is presented to the user. The contextual information consists of a semantic scale and a pathway to the information they are viewing. An information structure represents the immersive information space of documents. The information structure consists of a collection of documents, and a graph of topics that describe the relationships between the documents. The graph of topics consists of topic nodes that each contain 1) a set of documents that are about that topic, and 2) a set of links to other topics in the structure. The links represent relationships between topics, and indirectly, relationships between the documents. An information structure that represents the collection of documents is used to guide the user to documents of interest and to show relationships between documents. A presentation and interaction model allows navigation through the information structure. The model includes a camera representing a user's focus of attention, and a set of reactable graphical objects representing nodes in the information structure. The interaction model continuously monitors the movement of the camera in relation to the graphical objects and updates the display of the information space.

Immersive movement-based interaction with large complex information

A system, method, and software product create contextual hypertext links relevant to a user selected portion of a source document. The contextual links enable the user to dynamically associate the source document with any available target document, regardless of whether links where created between the source document and the target document when the source document was created. The method includes selecting terms relevant to the user selected portion by linguistic analysis which selects the most frequently occurring terms. From the selected terms target documents relevant to the selected terms are identified. The target documents are selected by identifying topics that are associated with, or described by, the selected terms. Contextual links are created between the selected terms and target documents associated with the identified topics using the URLs for the documents in the contextual links. The system includes a knowledge base of topics, including hierarchical relations between topics, and associations of topics and terms. A document collection includes documents and references to documents, and URL or other addressing information for the documents. A tagging module receives a user selected portion and selects terms to be used for the contextual links. A presentation module identifies the topics in the knowledge base associated with the selected terms, the documents associated with each topic, and creates the hypertext links between the terms and the documents.
