Mediated Reality Content Segmentation for Memory Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In first-person perspective-mediated reality, existing technologies face challenges in dynamically managing and rendering mediated reality content based on a user's changing point of view, leading to inefficiencies in content storage and rendering, particularly when memory management and content availability status are concerned.
Innovation Solution
An apparatus and method that allow users to select and render a first subset of mediated reality content based on their current point of view, while storing a second subset for potential future rendering, with the option to augment the first subset with alerts regarding the second subset, triggered by memory management, content availability, or event detection, enabling jump-transitions between different viewpoints and timelines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the system stores a second subset of mediated reality content for potential future rendering, then content availability for future viewpoints is improved, but memory usage increases
Solution Approach 1:
The patent segments the total mediated reality content into multiple subsets: a first subset currently being rendered to the user, a second subset stored for potential future rendering, and potentially additional subsets. This segmentation allows the system to manage memory by only storing and processing relevant portions of content at any given time, rather than loading all content into memory simultaneously.
Solution Approach 2:
The system performs preliminary actions by pre-storing the second subset of content in memory before it is actually needed for rendering. This allows the content to be readily available when the user's viewpoint changes, eliminating the need for time-consuming on-the-fly processing or regeneration of the content, while still maintaining a limited memory footprint by not storing all possible content variations.
2Speed
If the system renders content based on real-time viewpoint changes, then user experience responsiveness is improved, but processing load increases
Solution Approach 1:
The system performs preliminary processing and preparation of the second subset of content in advance, storing it in a ready-to-render state in memory. When the user's viewpoint changes, the system can immediately switch to rendering the pre-prepared content without requiring intensive real-time processing, thus maintaining high responsiveness while reducing peak processing loads.
3Quantity of substance
If the system manages memory by degrading resolution or time-shifting content, then memory efficiency is improved, but content quality deteriorates
Solution Approach 1:
The patent divides content into multiple temporal segments (different time periods or frames) and spatial segments (different subsets). The system can selectively degrade or compress less important segments (e.g., background elements, less critical time periods) while maintaining high quality for currently rendered content, thus achieving memory efficiency without uniformly sacrificing content quality.

AI summary
An apparatus comprising means for: enabling user-selection of a first sub-set of available mediated reality content based on a current point of view of a user; throughout a first period of time, causing rendering of the selected first sub-set of available mediated reality content to the user as it is selected; throughout the first period of time, storing a second sub-set of the available mediated reality content for potential future rendering, wherein the second sub-set is different to the first sub-set being rendered to the user and is not being rendered to the user during the first period of time; during at least a latter portion of the first period of time, determining whether or not to augment the user-selected first sub-set of available mediated reality content to include an alert concerning the second sub-set of available mediated reality content.
