Boundary Display Control for VR Head-Mounted Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In virtual reality (VR) technology, users wearing head-mounted displays (HMDs) experience an oppressive feeling due to the display of virtual objects representing boundary surfaces when approaching the boundary between permitted and unpermitted regions, especially in narrow spaces.
Innovation Solution
A boundary display control device that includes a user locating section, an approach portion identifying section, and a display control section to selectively display a virtual object representing the boundary surface only at a closer distance, adjusting the reference distance based on the user's position and using multiple sensors with different reference distances, and displaying a virtual ripple or highlighting edges to notify the user of the boundary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all virtual objects representing the boundary surface are displayed when the user approaches the boundary, then the user is notified of the boundary location, but the user feels oppressive especially in narrow permitted regions
Solution Approach 1:
The patent applies local quality by displaying virtual objects only at specific local areas of the boundary surface where the user is approaching, rather than displaying the entire boundary surface. The approach portion identifying section identifies specific regions of the boundary surface based on user position and direction, and only displays virtual objects in those identified portions, creating a localized notification system that reduces visual overload while maintaining boundary awareness.
2Reliability
If virtual objects are displayed to prevent user contact with objects in real space, then safety is improved, but the immersive feeling is reduced due to excessive virtual object display
Solution Approach 1:
The patent implements partial action by displaying only a portion of the boundary surface representation rather than the complete boundary. The display control section selectively renders virtual objects in identified approach portions based on user position, movement direction, and distance to the boundary, providing sufficient safety information without overwhelming the user with excessive visual elements that would compromise immersion.

AI summary
Provided are a boundary display control device, a boundary display control method, and a program which can reduce an oppressive feeling of a user when a virtual object representing a boundary surface dividing a region in a real space in which the user is permitted to exist from a region in the real space in which the user is not permitted to exist is displayed. A program executing section (84) locates a position of the user wearing a head-mounted display. An approach portion identifying section (86) identifies, as an approach portion, a part of a boundary surface dividing a permitted region that is the region in the real space in which the user is permitted to exist from an unpermitted region that is the region in the real space in which the user is not permitted to exist, on the basis of the located position of the user. A display control section (92) causes the head-mounted display to display a virtual object representing the identified approach portion.
