Augmented Reality Gating Mechanism for Privacy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing augmented reality systems raise privacy concerns as they capture and transmit sensitive images without user consent, deterring users from using these devices, especially in private or sensitive spaces.
Innovation Solution
An augmented reality display system with a detachable camera that, when attached, allows full data transmission, including images, while preventing image transmission when detached, using a gating mechanism to control data flow based on camera attachment, ensuring only geometric information is shared without images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the AR system captures and transmits images from sensors to provide accurate augmented reality experience, then the quality and realism of AR experience is improved, but user privacy is compromised due to potential capture of sensitive images without consent
Solution Approach 1:
The patent extracts the harmful element (image data) from the data transmission stream by implementing a gating mechanism that selectively blocks image data while allowing geometric information to pass through. This separates the useful geometric data from the potentially harmful image data, resolving the contradiction between AR quality and privacy protection
Solution Approach 2:
The gating mechanism acts as an intermediary component between the sensors and the data transmission system. It mediates the data flow by intelligently filtering out image data that could violate privacy while permitting geometric information necessary for AR functionality, thus resolving the conflict between experience quality and privacy
2Measurement precision
If the system transmits all sensor data including images to mobile platform for processing, then the processing accuracy and AR rendering quality is improved, but the data transmission volume and processing complexity increases
Solution Approach 1:
The gating mechanism extracts and removes redundant image data from the transmission stream, keeping only the essential geometric information. This reduction in data volume directly addresses the contradiction by transmitting less data while maintaining the processing accuracy needed for AR rendering
Solution Approach 2:
The patent segments the sensor data into distinct categories (image data and geometric information) and selectively transmits only the necessary geometric portion. This segmentation approach reduces overall data transmission volume while preserving the accuracy-critical geometric data for AR processing
