XR Extremity Visibility Control for Context and Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented and virtual reality systems struggle to seamlessly integrate user extremities into the XR environment, leading to inconsistent user experiences and potential privacy issues.
Innovation Solution
A mechanism is provided to enable applications to specify preferences for the visibility of user extremities, allowing the system to override application preferences based on predefined conditions for enhanced user interaction and privacy, using anchor points and real-time tracking for accurate representation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the system automatically determines extremity visibility without user input, then the system operation is simplified, but the adaptability to different user preferences and contexts is reduced
Solution Approach 1:
The system dynamically adjusts extremity visibility based on real-time context detection (activity type, environment, time of day) rather than using static default settings. The visibility state changes automatically according to detected conditions, balancing ease of operation with adaptability to different scenarios.
Solution Approach 2:
The system incorporates feedback mechanisms where user interactions (manual overrides, preference settings) and contextual feedback (activity detection, environment sensing) continuously inform the visibility decision. This feedback loop allows the system to adapt to both immediate context and user preferences while maintaining simple operation.
2Adaptability or versatility
If the system provides granular control over extremity visibility settings, then the adaptability to different preferences is improved, but the device complexity increases
Solution Approach 1:
The visibility control is segmented into multiple independent dimensions: per-extremity control (left hand, right hand, feet), per-application control, and context-based control. This segmentation allows granular adaptability without requiring a single complex monolithic setting, distributing complexity across manageable components.
Solution Approach 2:
The system provides a universal visibility management framework that handles multiple scenarios (different applications, contexts, user preferences) through a unified mechanism. The same core system handles both automatic context-based visibility and manual granular control, reducing overall system complexity compared to separate solutions.
3Ease of operation
If the system displays user extremities in XR environments, then the user interaction and immersion are improved, but privacy concerns and user discomfort increase
Solution Approach 1:
The system applies preliminary anti-action by detecting privacy-sensitive contexts (e.g., when user is alone, specific activity types) and automatically adjusting visibility before user discomfort or privacy violations can occur. The system proactively prevents harmful situations rather than reacting after they arise.
Solution Approach 2:
The visibility of extremities is made dynamic and context-dependent rather than static. The system continuously monitors context (activity, environment, time) and adjusts visibility in real-time, allowing high interaction quality when appropriate while automatically reducing visibility when privacy risks are detected.

AI summary
A system process of a device can receive a visibility preference corresponding to a physical object type. A physical object can be identified as being visible in a physical environment of the device and, in response to identifying that the physical object corresponds to the physical object type, the system process can control visibility of a representation of the physical object in a display output based at least in part on the visibility preference. The system process can override the visibility preference based on the interaction with physical objects in the physical environment and other factors.
