VR Display Control for Simultaneous Reference Material Browsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Viewers in presentations face inconvenience due to the fixed positional relationship between display devices and their viewing positions, requiring repeated eye movements to switch between the main presentation content and desired reference materials, which are not addressed by existing VR technologies.
Innovation Solution
A display control system that allows for the simultaneous display of main presentation materials and reference materials in a virtual reality space, enabling viewers to change the display manner of reference materials based on their input, such as position, size, and page changes, independent of their physical viewing position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If presentation materials are displayed on a terminal at hand of each viewer separately from a display device for all viewers, then viewers can check content other than content presently displayed on the display device, but viewers cannot simultaneously see content displayed on the display device and content on their terminal due to fixed positional relationship
Solution Approach 1:
The patent introduces a mobile terminal as an intermediary device between the main display device and the viewer. The terminal receives presentation materials from the display device and displays them locally, enabling viewers to browse reference materials without moving their eyes from the main display. This mediator resolves the contradiction by providing a local copy of materials that can be viewed simultaneously with the main presentation.
Solution Approach 2:
The patent transitions from a single-dimensional viewing experience (one display device for all viewers) to a multi-dimensional setup where each viewer has both the main display view and a personal terminal view. This dimensional expansion allows simultaneous access to different content streams without physical eye movement, resolving the spatial contradiction.
2Device complexity
If the positional relationship of displayed positions of respective materials are fixed with respect to the position of the display device and the position of the viewer, then the display structure is simple, but viewers have to repeat actions to largely change the sight line to check both presentation content and reference material
Solution Approach 1:
The mobile terminal acts as a mediator that receives and displays presentation materials locally. This allows the main display device to maintain its fixed position and simple structure while the terminal provides flexible, localized content access, eliminating the need for viewers to move their eyes between distant materials and the main display.
Solution Approach 2:
The patent creates a copy of the presentation materials on each viewer's mobile terminal. This copy can be displayed simultaneously with the main presentation content, allowing viewers to reference materials without returning their gaze to the main display. The copying mechanism resolves the time loss by making reference materials immediately accessible in the viewer's field of view.
3Adaptability or versatility
If a viewer uses a mobile terminal to browse presentation materials, then the viewer can check desired pages independently, but the viewer cannot simultaneously see the main display content and terminal content due to fixed positional relationships
Solution Approach 1:
The mobile terminal serves as an intermediary that receives presentation materials from the main display device and displays them locally for independent browsing. This intermediary function enables simultaneous viewing of both main display content and terminal content by positioning the terminal within the viewer's field of view, resolving the contradiction between independent access and simultaneous viewing.

AI summary
A display control device includes a first display control unit performing control so as to display a page, which is being displayed in a real space, in a first material as a presentation material used in a presentation by a presenter in a first position in a virtual reality space, a second display control unit performing control so as to display a second material in a second position which is different from the first position in the virtual reality space, and an operation input information acquisition unit acquiring first operation input information as operation input information which is input by a viewer experiencing the virtual reality space and which is about display of the second material, in which the second display control unit changes a display manner of the second material based on the first operation input information.
