VR Information Display Objects Visibility Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In head-mounted display (HMD) systems for virtual reality, information display objects often become difficult to see or deteriorate the virtual reality experience due to inappropriate display, especially when the user's line-of-sight direction changes and there are many objects in the VR space.
Innovation Solution
A simulation system that arranges information display objects in the line-of-sight direction of the user and changes their display mode based on conditions such as point-of-view changes, type, priority, and elapsed time, using techniques like erasure, semi-transparentization, movement, and size changes to ensure appropriate visibility and prevent obstruction of the user's field of view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information display objects are displayed in the virtual reality space, then the user can access descriptive information and status information, but the screen becomes hard to see and virtual reality is deteriorated when the user's line-of-sight direction changes
Solution Approach 1:
The display mode of information display objects is dynamically changed based on the user's line-of-sight direction and point-of-view changes. When the user's gaze moves away from an information object, the system automatically adjusts its display mode (e.g., reduces size, changes transparency, or moves it to the periphery), ensuring information remains accessible while minimizing disruption to the virtual reality experience.
Solution Approach 2:
Different display modes are applied to different information display objects based on their priority, type, and position relative to the user's line of sight. High-priority information maintains visibility even when the user looks away, while lower-priority information is adjusted more aggressively to prevent screen obstruction and virtual reality deterioration.
2Loss of information
If multiple information display objects are arranged in the VR space, then comprehensive information is provided to the user, but the field of view is obstructed and the screen becomes hard to see
Solution Approach 1:
Information display objects are arranged in three-dimensional space rather than flat two-dimensional screens. The system utilizes depth, position, and spatial relationships to display multiple information objects without obstructing the user's field of view. Objects can be positioned at different depths and angles, allowing comprehensive information display while maintaining clear visibility of the virtual environment.
Solution Approach 2:
The position, size, and transparency of information display objects are dynamically adjusted based on the user's point of view and line of sight. When an information object would obstruct the user's view, the system automatically moves it to the periphery, reduces its size, or adjusts its transparency, ensuring comprehensive information is available without field of view obstruction.
3Ease of operation
If information display objects are made visible and prominent, then information is easily accessed by the user, but the virtual reality experience is deteriorated due to screen obstruction
Solution Approach 1:
The system uses color and transparency changes to indicate the status and priority of information display objects. High-priority information uses more prominent colors and higher opacity, while lower-priority information uses subtler colors and lower opacity. This allows easy information accessibility through color coding while minimizing screen obstruction through transparent or semi-transparent displays.
Solution Approach 2:
The display prominence of information objects is dynamically adjusted based on user interaction and context. When the user focuses on or interacts with an information object, it becomes more prominent and accessible. When the user's attention shifts elsewhere, the object's prominence is reduced to minimize screen obstruction, maintaining ease of operation when needed while preventing virtual reality deterioration during normal viewing.

AI summary
A simulation system includes a processor including hardware. The processor performs: a virtual space setting process of setting a virtual space in which a plurality of objects are arranged; a virtual camera control process of controlling a virtual camera corresponding to a point-of-view of a user wearing a head mounted display; and a display process of generating an image as viewed from the virtual camera in the virtual space as a display image on the head mounted display. In the virtual space setting process, the processor arranges at least one information display object in a line-of-sight direction of the user, and in the display process, when it is determined that a given change condition is satisfied by a change in the point-of-view of the user, the processor performs a change process of a display mode of the information display object.
