VR Content Display Using 3D Thiessen Space Division
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VR devices limit user experience by presenting content in a two-dimensional plane, failing to provide effective space immersion despite offering panoramic views, as users interact with content like icons and videos in a manner similar to conventional screen devices.
Innovation Solution
A method and apparatus for displaying content in a three-dimensional space within VR scenes, where the initial user position and to-be-displayed objects are determined, and space boundaries are defined using the 3D Thiessen space division method to create distinct display spaces for each object, allowing for dynamic and interactive three-dimensional placement and interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If content is displayed on a two-dimensional operable platform in VR scenes, then the user can interact with content like application icons and video thumbnails, but the user experience remains limited to conventional screen display devices and cannot achieve effective space immersion
Solution Approach 1:
The patent transitions from two-dimensional plane display to three-dimensional space display by defining display spaces using 3D Thiessen space division. Content is positioned in three-dimensional coordinate systems rather than on flat screens, allowing users to interact with objects in volumetric space while maintaining ease of operation through natural spatial relationships.
Solution Approach 2:
The patent divides the three-dimensional VR space into distinct display spaces for different content types (application icons, video thumbnails, file lists) using space division algorithms. Each content type receives its own designated three-dimensional region, enabling independent interaction while maintaining overall spatial coherence and immersion.
2Adaptability or versatility
If content is displayed in a three-dimensional space using Thiessen space division, then the user experience of space immersion is improved, but the device complexity and computational requirements increase
Solution Approach 1:
The system automatically performs space division and content positioning using algorithms that compute Thiessen polyhedra based on content coordinates. The computational complexity is managed through efficient mathematical formulations that self-adjust to the number and distribution of content objects, reducing the need for manual configuration and lowering operational complexity.
3Stability of the object's composition
If multiple to-be-displayed objects are positioned on a virtual sphere surface, then the content can be evenly distributed in three-dimensional space, but the calculation complexity for determining display positions increases
Solution Approach 1:
The patent pre-establishes a virtual sphere with the user's initial position as the center and viewing distance as the radius. This preliminary geometric framework provides a ready-made structure for distributing content objects uniformly across the sphere surface, eliminating the need for complex real-time calculations during content display and simplifying the positioning process.

AI summary
A content display method, apparatus and device. Said method comprises determining an initial position of a user in a VR scene (101); determining, in the VR scene, at least one object to be displayed and the display position of each of said objects in the VR scene (102); according to the display position of each of said objects and the initial position of the user, dividing the VR scene to obtain respective spatial boundaries of the user and each of said objects, and creating respective display spaces for the user and each of said objects (103); and displaying each of said objects in the respective display space (104). The three-dimensional scene-based content display method enables a user to be in a three-dimensional space at every moment, thus providing a better spatial immersion experience.
