Hyperbolic Projection for Knowledge Domain Navigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional visualization techniques struggle to effectively convey the network structure of complex knowledge domains, leading to difficulties in building a comprehensive mental picture and seamless navigation between comprehensive overviews and detailed views.
Innovation Solution
A user interface that transitions seamlessly from an undistorted, fully zoomable projection to a distorted hyperbolic projection, allowing related content to fade out and move towards the focus topic, providing a fisheye view that maintains semantic proximity and allows for continuous navigation without disorientation.

Engineering Contradiction Analysis
1Loss of information
If conventional visualization techniques are used to represent complex knowledge domains, then the visualization can cover limited complexity, but it cannot properly convey the network structure inherent to complex knowledge domains
Solution Approach 1:
The patent transitions from traditional 2D flat visualizations to a 3D spherical projection space. This dimensional change allows the system to represent complex network structures by mapping topics onto the surface of a sphere, where geometric proximity naturally encodes semantic relatedness. The spherical geometry provides additional spatial dimensions for organizing and displaying interrelated topics without the constraints of planar layouts.
Solution Approach 2:
The system implements dynamic navigation where the spherical projection can be rotated, zoomed, and reconfigured in real-time. Topics can be selected and emphasized by positioning them at the apex of the spherical projection, while less important topics are positioned lower on the sphere. This dynamic reconfiguration allows the visualization to adapt to different exploration needs and maintain clarity even as the complexity of displayed information increases.
2Loss of information
If multiple visual representations are used to cover complex content, then different topics or views can be presented, but it is difficult to build a comprehensive mental picture from disconnected representations
Solution Approach 1:
The patent merges multiple topic representations into a single unified spherical projection. Instead of displaying separate visualizations that require switching between views, all topics are simultaneously represented on the spherical surface with their relative positions reflecting semantic relationships. This unified view allows users to see the comprehensive structure of the knowledge domain while maintaining the ability to focus on individual topics by positioning them at the apex.
Solution Approach 2:
The spherical projection acts as an intermediary space that bridges the gap between individual topics and the overall knowledge structure. By mapping topics onto the sphere with geometric proximity encoding semantic relatedness, the system provides a natural transition mechanism where users can move from viewing individual topics to understanding their relationships within the broader domain through continuous spatial navigation.
3Loss of information
If traditional navigation techniques are used, then sequential views can be presented, but they cannot express the relatedness of topics by geometric proximity
Solution Approach 1:
The system uses visual encoding where the position of topics on the spherical projection serves as a geometric representation of semantic relatedness. Topics that are semantically related are positioned closer together on the sphere's surface, while less related topics are positioned farther apart. This geometric encoding allows users to intuitively understand relationships without requiring complex visual cues or additional information channels.
4Loss of information
If comprehensive overview is provided with detailed focused views, then complete knowledge domains can be visualized, but geometrical constraints prevent seamless integration
Solution Approach 1:
The spherical projection provides an additional spatial dimension for organizing information hierarchically. The apex of the sphere serves as the focal point for detailed views, while the broader spherical surface maintains the comprehensive overview. This dimensional arrangement allows seamless transitions between overview and detail by simply changing the apex position, without requiring separate visualization modes or breaking the geometric continuity of the display.

AI summary
A system stores visual content, and displays the visual content on a display unit in an undistorted, overview projection. The system receives input from a user to focus on a topic in the undistorted, overview projection, and transforms the undistorted, overview projection into a focused display showing the topic selected by the user and content related to the topic selected by the user in a continuous sequence of increasingly distorted projections. In the focused display, the content that is not related to the topic selected by the user does not move on the focused display, and the content that is related to the topic selected by the user moves towards the topic selected by the user on the focused display.
