Virtual Space Content Scaling for Viewpoint-Based Size Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual space presentation technologies fail to display various contents in suitable sizes due to uniform enlargement or reduction, neglecting differences in content definitions, and methods like Patent Literature 1 do not allow optimal sizing of all contents.
Innovation Solution
A virtual space presentation device with a virtual space generation unit, display control unit, detection unit, virtual space correction unit, and display correction unit adjusts content sizes based on the user's actions, associating different sizes with each content and applying display magnifications to maintain optimal appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire virtual space is uniformly enlarged or reduced, then the virtual space can be adjusted to fit different viewing conditions, but all contents are similarly enlarged or reduced without considering differences in content definition, resulting in inappropriate content sizes
Solution Approach 1:
The patent segments the virtual space into multiple regions, each dedicated to specific types of content. By dividing the space into content-specific zones with predetermined size parameters, the system can apply different scaling rules to different content types while maintaining overall virtual space adaptability. This resolves the contradiction by allowing uniform virtual space adjustment while preserving individual content size accuracy through regional segmentation.
Solution Approach 2:
The patent implements local quality by assigning different size characteristics to different regions within the virtual space. Each content region has optimized size parameters tailored to its specific content type (e.g., video, image, text). When the virtual space is scaled, each region maintains its appropriate size ratio, ensuring that content definition differences are respected while the overall space adapts to viewing conditions.
2Measurement precision
If a specific region is enlarged as in Patent Literature 1, then the watched region can be displayed in detail, but it is not possible to display all contents in suitable sizes simultaneously
Solution Approach 1:
The patent implements dynamic scaling where the enlargement ratio of each content region is not fixed but adjusts based on the user's viewpoint position and the importance of each content type. When a user focuses on a specific region, that region is enlarged while other regions maintain appropriate sizes based on their content definitions. This dynamic adjustment allows detailed viewing of watched regions while preserving suitable display sizes for all contents through continuous adaptation.
Solution Approach 2:
The patent changes size parameters dynamically based on content type and user interaction. Each content region has base size parameters defined by its content definition, and these parameters are adjusted according to viewpoint position and content priority. This parameter change mechanism enables the system to provide detailed views of watched regions while maintaining appropriate sizes for all other contents, resolving the contradiction between detail and versatility.

AI summary
A virtual space presentation device includes a virtual space generation unit generating a virtual space including a virtual viewpoint of a user inside to allocate a content into the virtual space, a display control unit displaying the virtual space on a display unit, a detection unit detecting an action of the user, a virtual space correction unit moving the virtual viewpoint to correct the virtual space, and a display correction unit displaying the corrected virtual space on the display unit. The virtual space correction unit computes a display magnification on the basis of the virtual viewpoint, a first size applied to the content in a case where the virtual viewpoint is positioned at the center of the virtual space, and a second size different from the first size, and allocates the content to which a size according to the computed display magnification is applied to the corrected virtual space.
