Mediated Reality Headset Display Control for Image Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mediated reality headsets suffer from image leakage, which can create visible bright spots and compromise privacy by allowing third parties to see the content, affecting eye contact and visibility.
Innovation Solution
A data-processing apparatus identifies portions of the image likely to leak into the field of view of an object and modifies the display to reduce light leakage by techniques such as moving, changing brightness, or temporarily stopping the display of those portions.

Engineering Contradiction Analysis
1Illumination intensity
If light guides are used to display images in mediated reality headsets, then image display functionality is improved, but light leakage occurs that compromises privacy and creates visible bright spots
Solution Approach 1:
The image is divided into multiple portions, with different display treatments applied to each portion based on its leakage risk. High-risk portions are modified or hidden, while low-risk portions are displayed normally, thus reducing overall light leakage while maintaining image functionality.
Solution Approach 2:
Different display strategies are applied to different regions of the image based on their specific leakage characteristics. Portions of the image that are more prone to leakage are treated differently from those less prone to leakage, optimizing privacy protection where needed while preserving display quality where safe.
2Object-affected harmful factors
If portions of the image are modified to reduce light leakage, then privacy is improved, but the completeness and quality of the displayed image deteriorates
Solution Approach 1:
Only the necessary portions of the image that pose privacy risks are modified or hidden, rather than modifying the entire image. This partial action approach maintains image completeness and quality for non-sensitive regions while providing privacy protection where required.
Solution Approach 2:
The system introduces an intermediary processing layer that selectively modifies image portions based on leakage risk assessment. This intermediary layer acts as a mediator between the original image and the display, preserving privacy-critical information while maintaining overall image quality and completeness.
3Object-affected harmful factors
If the display is modified to prevent light leakage in certain portions, then privacy is enhanced, but the field of view and visibility for the user is reduced
Solution Approach 1:
The display area is segmented into regions with different privacy risk levels. Only segments with high leakage risk are modified, while other segments maintain full visibility and field of view, thus minimizing the impact on user experience while providing targeted privacy protection.

AI summary
Examples of the disclosure are configured to reduce the effects of leaked images from mediated reality headsets. Examples of the disclosure comprise determining that an object is positioned relative to a mediated reality headset such that one or more portions of an image displayed by the mediated reality headset could be leaked in a field of view of the object. Examples of the disclosure also comprise identifying one or more portions of the image that are displayed by the mediated reality headset such that leakage of those one or more portions is expected to be in the field of view of the object. Examples of the disclosure also comprise causing modification of the display of the image by the mediated reality headset wherein the modification reduces light leakage for the one or more portions of the image that are identified as being displayed such that leakage of those one or more portions is expected to be in the field of view of the object.
