Posture-Adaptive Virtual Space Layout for Seated VR Interaction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing artificial reality systems fail to account for user posture, leading to difficulties in interacting with virtual objects, collisions with real-world objects, and inefficient virtual space configurations, particularly when users are seated or lying down.
Innovation Solution
A virtual space configuration system that detects user posture to customize virtual space settings, including adjusting floor height, object placement, boundary displays, and enabling seated-only experiences, using machine learning and sensor data to enhance user interaction and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user interacts with virtual objects in an artificial reality environment, then the user experiences immersive virtual content, but the user may collide with real-world objects or exit designated areas
Solution Approach 1:
The system dynamically adjusts virtual space boundaries and object placements based on the user's physical movements and posture detected by sensors. The virtual environment responds in real-time to user actions, modifying the playable area and object positions to maintain safety while preserving user freedom of movement.
Solution Approach 2:
The system continuously monitors user position and physical environment through sensors, providing real-time feedback by adjusting virtual boundaries and issuing warnings when the user approaches real-world obstacles or designated area limits, thereby preventing collisions while maintaining immersive interaction.
2Adaptability or versatility
If virtual objects are placed out of reach to expand virtual space, then the virtual environment offers more content, but the user cannot interact with them from their current posture
Solution Approach 1:
The system dynamically repositions virtual objects within reach based on the user's detected posture and movement capabilities. When objects are placed beyond the user's accessible range, the system automatically adjusts their positions to maintain interaction feasibility while preserving the intended virtual space layout.
Solution Approach 2:
The system applies different spatial configurations to different regions of the virtual environment based on user posture. Virtual objects are selectively repositioned or scaled in the user's immediate interaction zone while maintaining their original positions in distant areas, creating localized accessibility without compromising overall virtual space design.
3Adaptability or versatility
If the virtual space configuration is fixed to simplify system design, then the system is easier to implement, but it cannot accommodate different user postures and movements
Solution Approach 1:
The system transitions from fixed virtual space configurations to dynamic, posture-adaptive configurations. Sensors detect user posture and movement, triggering automatic adjustments to virtual boundaries, object placements, and interaction parameters, thereby accommodating diverse user positions without requiring multiple pre-configured modes.
Solution Approach 2:
The system automatically detects user posture through sensors and self-adjusts virtual space configurations without requiring manual user input or complex configuration interfaces. The artificial reality system serves itself by autonomously optimizing the virtual environment based on real-time posture data, reducing the burden on users and simplifying the interaction model.

AI summary
A virtual space configuration system of an artificial reality system can detect a user posture and provide various corresponding customizations of the system's virtual space. The virtual space configuration system can, when a user is in a seated posture, provide for seated virtual space customizations. In various implementations, these customizations can include allowing adjustment of a floor height; setting a flag that can be surfaced to applications to adjust the applications' mechanics for seated users; customizing display of virtual space boundaries when in seated mode to be less intrusive; providing options to detect when a user leaves seated mode and trigger corresponding actions; provide a passthrough workspace area allowing a user to interact with certain real-world objects naturally without having to remove a virtual reality headset; or automatically determining virtual space dimensions for seated users.
