Dynamic Boundary Management for Artificial Reality User Movement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional artificial reality systems lack flexible and dynamic boundaries that adapt to user movements, leading to inflexible system functionality and unmitigated disruption of the user experience.
Innovation Solution
Implement a dynamic boundary manager that generates a boundary based on user movements, allowing for expansion, popping, and reforming of the boundary in response to predefined criteria, thereby triggering changes in system operations such as transitions between virtual and pass-through environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixed boundary is implemented in artificial reality systems, then system safety is improved, but system flexibility and user experience are worsened
Solution Approach 1:
The patent implements a dynamic boundary that automatically adjusts its parameters (position, size, shape) based on real-time user movement data. Instead of a fixed boundary, the system continuously updates the boundary definition to match user behavior patterns, thereby maintaining safety while adapting to different usage scenarios and improving system flexibility.
Solution Approach 2:
The system changes boundary parameters (location, dimensions, orientation) dynamically based on user movement analysis. The boundary manager monitors user position and velocity, then adjusts boundary parameters accordingly - expanding when user movement is controlled, contracting or relocating when safety concerns arise, thus resolving the contradiction between fixed safety boundaries and flexible adaptation.
2Adaptability or versatility
If a dynamic boundary is implemented that adapts to user movements, then system flexibility is improved, but system complexity is worsened
Solution Approach 1:
The boundary manager system performs self-adjustment by automatically monitoring user movement data and updating boundary parameters without requiring external intervention or complex manual configuration. The system serves itself by integrating the boundary management functionality within the artificial reality system architecture, using existing sensor data and processing capabilities to maintain the dynamic boundary.
Solution Approach 2:
The system implements a feedback loop where user movement data is continuously monitored and fed back to the boundary manager, which then adjusts boundary parameters accordingly. This closed-loop control mechanism enables automatic adaptation to user behavior while keeping the system architecture relatively simple, as the feedback drives the boundary adjustments without requiring complex external control systems.
3Ease of operation
If the boundary is expanded in response to user movements, then user freedom of movement is improved, but safety monitoring difficulty is worsened
Solution Approach 1:
The boundary dynamically expands and contracts based on real-time analysis of user movement characteristics. When user movement is slow and controlled, the boundary expands to provide greater freedom of movement. When movement speed increases or unsafe patterns are detected, the boundary contracts or relocates to maintain safety, thus resolving the contradiction between user freedom and safety monitoring.
Solution Approach 2:
The system performs preliminary analysis of user movement patterns and anticipates potential safety issues before they occur. By monitoring velocity and position trends, the system can proactively adjust the boundary to prevent unsafe situations, making safety monitoring more effective even as the boundary expands to provide user freedom.

AI summary
Aspects of the present disclosure are directed to a dynamic boundary that triggers operating changes at an artificial reality system. Implementations of a dynamic boundary manager can enforce dynamic boundary criteria. A dynamic boundary that corresponds to the user can be automatically generated, such as when the artificial reality system operates in a certain operating condition. User movements can trigger dynamic boundary criteria and cause one or more of: expansion of the dynamic boundary; popping of the dynamic boundary; and/or reforming of the dynamic boundary. Responsive to these triggers, the dynamic boundary manager can also cause changes to operations at the artificial reality system, such as pause(s) to executing applications and/or changes to the artificial reality environment displayed to the user (e.g., transitions to and from a virtual reality environment, a pass-through visual, etc.).
