Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing virtual reality systems fail to prevent interactions between virtual objects and real-world obstacles, leading to potential user injury or property damage when users move during an interactive session.
Innovation Solution
An apparatus and method that detects potential interactions between virtual objects and real-world structures, modifying the virtual object's position to avoid overlap or proximity with physical structures, and providing indicators for safe interaction resumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the virtual scene allows free interaction with virtual objects, then the user experience and interactivity are improved, but the risk of collision with real-world obstacles increases
Solution Approach 1:
The system performs preliminary detection of real-world obstacles using depth sensors and spatial mapping before allowing virtual object interaction. Virtual objects are positioned and constrained in advance to prevent overlap with detected physical structures, thereby preventing harmful collisions before they can occur.
Solution Approach 2:
The system pre-maps the real-world environment and identifies safe interaction zones before the user begins interacting with virtual objects. This preliminary spatial understanding allows the system to guide users to safe positions and restrict virtual object placement in hazardous areas.
2Reliability
If the system restricts virtual object positions to avoid real-world obstacles, then safety is improved, but the freedom of movement and exploration in virtual space deteriorates
Solution Approach 1:
The system dynamically adjusts virtual object positions and interaction constraints based on the user's current location and movement. As users move through the physical space, the virtual environment adapts by repositioning objects and updating safe interaction zones, maintaining both safety and exploration freedom throughout the session.
Solution Approach 2:
The system introduces virtual indicators and guides as intermediary elements that suggest safe interaction zones without completely restricting user freedom. These visual cues mediate between safety requirements and user exploration desires, allowing users to naturally navigate to safe areas while maintaining engagement.
3Reliability
If the system continuously monitors and modifies virtual object positions, then collision prevention is improved, but the computational complexity and processing requirements increase
Solution Approach 1:
The system segments the virtual scene into distinct interaction zones and groups virtual objects into categories based on their interaction requirements. This segmentation allows the collision detection and resolution system to process only relevant objects and zones, reducing computational complexity while maintaining comprehensive safety monitoring.
Solution Approach 2:
The system applies collision detection and position modification only to virtual objects that are currently within the user's field of view or near the user's position, rather than continuously monitoring all virtual objects. This partial action approach maintains safety for active interactions while reducing overall processing requirements.

AI summary
Example embodiments are disclosed relating to virtual content. Example embodiments may involve providing video data for output to a user device, the video data representing a virtual scene comprising one or more virtual objects at respective locations in the virtual scene with which a user of the user device may interact during an interactive session. The interactive session may be paused and a resumption input may be received at a second time, subsequent to the first time, for unpausing the interactive session. Responsive to receiving the resumption input, it may be detected that interaction with a particular virtual object, with which the user has interacted prior to the interactive session being paused, is restricted due to physical properties of a real-world space in which the user is located at the second time. The virtual scene may be modified to permit interaction with the particular virtual object without the detected restriction.
