VR Simulation System Spatial Field Segmentation for Collision Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users wearing head-mounted displays (HMDs) in virtual reality simulation systems have difficulty seeing their surroundings, leading to potential collisions with others or equipment, which can result in accidents during immersive experiences.
Innovation Solution
The simulation system employs a method where users are assigned to separate virtual fields corresponding to their real-world positions, with virtual moving bodies representing them in a common virtual space, allowing for a seamless and collision-free virtual reality experience by adjusting movement speeds and displaying special effects when proximity relationships are detected.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users wear HMDs to experience virtual reality, then virtual reality immersion is improved, but visibility of real surroundings deteriorates leading to collision risks
Solution Approach 1:
The system segments the virtual space into multiple fields corresponding to different real-world locations. Users are assigned to specific fields based on their physical positions, creating spatially separated virtual environments that prevent collisions while maintaining immersion.
Solution Approach 2:
The system introduces field management as an intermediary layer between the user's physical position and their virtual representation. This intermediary assigns users to appropriate fields and manages their movements within those fields, preventing collisions without compromising the virtual reality experience.
2Reliability
If users are placed in a common virtual space, then virtual reality experience is enhanced, but collision between users increases
Solution Approach 1:
The common virtual space is segmented into multiple distinct fields, each corresponding to a specific real-world location. Users are assigned to fields based on their physical positions, allowing them to experience a shared virtual environment while maintaining spatial separation that prevents collisions.
Solution Approach 2:
The system adds a spatial organization dimension to the virtual space by creating multiple fields. This dimensional organization allows users to coexist in the same virtual environment while being separated into different spatial zones, enabling both immersion and collision prevention.
3Object-affected harmful factors
If multiple fields are prepared in real space, then collision prevention is improved, but system complexity increases
Solution Approach 1:
The field management system serves multiple functions: it prevents collisions by spatially separating users, maintains virtual reality immersion, and organizes users based on their physical positions. This multi-functional approach manages complexity by consolidating several objectives into a unified system.
Solution Approach 2:
The system dynamically changes the field assignment parameter based on users' real-world positions. When users move physically, their virtual field assignments are updated accordingly, allowing the system to maintain collision prevention without requiring manual reconfiguration or complex static planning.

AI summary
A simulation system includes a processor including hardware. The processor performs an information acquisition process of acquiring position information of a user wearing a head mounted display to cover his/her field of view; a virtual space setting process of setting a virtual space where a moving body corresponding to the user is arranged and set based on the acquired position information; a moving body process of moving the moving body in the virtual space based on the acquired position information; and a display process of generating a display image on the head mounted display. In the virtual space setting process, the processor sets the virtual space such that a first moving body group and a second moving body group are arranged and set in a common virtual field of the virtual space.
