Viewpoint Video Display Control for Angle-Dependent Presence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies fail to effectively manage the perception of presence and sense of presence of specific individuals in virtual spaces, particularly through varying angles of view and image quality in mixed reality environments.
Innovation Solution
A display control device and method that adjusts the display of specific information based on the angle of view and image quality, using head-mounted displays to enhance the perception of presence by altering the visibility and quality of information based on the viewer's position and visual line direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple viewpoint videos are displayed to represent different persons in virtual space, then the sense of presence of specific persons is enhanced, but the complexity of display control increases
Solution Approach 1:
The patent applies local quality by adjusting the display characteristics (such as transparency, size, or position) of specific information based on the viewer's visual line direction and angle of view. Different regions of the display are treated differently according to where the viewer is looking, thereby enhancing the sense of presence for specific persons without uniformly increasing complexity across the entire display system.
Solution Approach 2:
The patent implements dynamics by making the display control adaptive and changeable based on real-time viewer position and gaze direction. The system dynamically adjusts which information is displayed and how it is presented, allowing the display control to respond to viewer behavior rather than following a fixed complex pattern.
2Reliability
If information is displayed with high image quality to improve perception, then the sense of presence is enhanced, but the energy consumption increases
Solution Approach 1:
The patent applies local quality by rendering high image quality only for the specific information that the viewer is currently looking at, while other regions are rendered with lower quality or not at all. This selective rendering approach maintains high perception quality for relevant information while significantly reducing the overall energy consumption of the display system.
Solution Approach 2:
The patent implements partial action by providing high-quality display only for the portion of information that is currently of interest to the viewer (determined by visual line direction), rather than maintaining high quality for all information simultaneously. This partial rendering strategy reduces energy consumption while preserving the necessary perception quality.

AI summary
A display control device includes a first acquisition unit that acquires first viewpoint position information, and a first control unit that performs a control of displaying a first viewpoint video selected from among a plurality of viewpoint videos generated based on images obtained by imaging an imaging region from a plurality of viewpoint positions on a first display unit, in which the first control unit performs a control of displaying first specific information for specifying a first viewpoint position in the first viewpoint video in a case in which the first viewpoint position indicated by the acquired first viewpoint position information is included in the first viewpoint video and performs a control of changing a display size of the first specific information depending on an angle of view of the first viewpoint video displayed on the first display unit.
