Display Control Unit for Virtual Object Visibility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing display technologies, the size of display objects changes based on their positional relation to the viewer, often occupying most of the angle of view, making it difficult for users to view the background sufficiently, especially in critical situations like dangerous or important work.
Innovation Solution
An information processing device and method that control display by specifying a first and second virtual object based on positional relations between content and the viewer's viewpoint, with the second object having lower visibility when the distance between them is shorter, ensuring the background remains visible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If the display size of a display object is increased to improve visibility of the content, then the content becomes more prominent and easier to see, but the background becomes harder to view and the angle of view is occupied
Solution Approach 1:
The patent applies local quality by making different parts of the display object have different transparency characteristics. The display object has a more transparent portion and a less transparent portion, allowing the background to be visible through parts of the display object while maintaining content visibility. This resolves the contradiction by enabling both content prominence and background viewability simultaneously through spatial differentiation of transparency properties.
2Loss of information
If the display object is positioned closer to the viewpoint to improve content prominence, then the content becomes more prominent in the field of view, but the background visibility is reduced
Solution Approach 1:
The patent positions the display object closer to the viewpoint while maintaining background visibility through local quality differentiation. By having portions of the display object with varying transparency, the system allows the prominent display object to coexist with background visibility, resolving the contradiction between content prominence and background visibility.
Solution Approach 2:
The patent resolves the positional contradiction by transitioning from a single-dimensional positioning problem to a multi-dimensional solution involving transparency as an additional dimension. Instead of only adjusting position, the system uses transparency as a second dimension to control visibility, allowing the display object to be positioned prominently while still permitting background viewability through transparent portions.

AI summary
An information processing device that includes a display control unit to perform display control such that a first virtual object corresponding to content is contained in a rendering image of the content when a position of the content defined in a virtual space and a position of a viewpoint defined in the virtual space have a first positional relation, and a second virtual object corresponding to the content is contained in the rendering image when the position of the content and the position of the viewpoint have a second positional relation. A distance between the position of the content and the position of the viewpoint in the second positional relation is shorter than a distance between the position of the content and the position of the viewpoint in the first positional relation, and visibility of the second virtual object is lower than visibility of the first virtual object.
