XR Viewing Environment Customization With Timed Metadata Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for viewing content on head-mounted devices (HMDs) and other electronic devices lack the ability to customize extended reality environments based on metadata within the content, limiting the immersive and interactive experience.
Innovation Solution
Implementing a method where video content items include additional timed tracks with environment customization information, allowing devices to synchronize and alter the XR environment during playback, incorporating metadata to customize objects, actions, and environment settings in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If video content is presented on a virtual screen in a static XR environment, then the viewing experience is simple and stable, but the environment cannot be customized to match the content
Solution Approach 1:
The patent applies preliminary action by embedding environment customization tracks and metadata within the video content itself before playback. The customization information is prepared in advance and synchronized with the video timeline, allowing the XR environment to be dynamically adjusted without requiring complex real-time processing or additional external systems during playback.
Solution Approach 2:
The video content item itself contains all necessary environment customization information through embedded tracks and metadata. The content is self-sufficient, carrying its own environment configuration data that enables the XR environment to be customized without requiring external configuration files or additional input from the playback system, thereby reducing overall system complexity.
2Adaptability or versatility
If the XR environment is dynamically customized during playback, then the immersive experience is enhanced, but synchronization between content and environment is difficult to achieve
Solution Approach 1:
The environment customization tracks are prepared in advance with precise timing information embedded in the video content metadata. This preliminary preparation ensures that environment changes are synchronized with content playback without requiring complex real-time coordination, as all timing data is predetermined and embedded in the content structure.
Solution Approach 2:
The system uses timing metadata embedded in the video content to provide feedback mechanisms that ensure synchronized playback. The metadata contains timing information that allows the playback system to monitor and adjust environment customizations in real-time to maintain precise synchronization with the video content, ensuring accurate alignment between visual content and environmental changes.
3Ease of operation
If environment customization information is embedded in the video content, then portability and ease of distribution are improved, but the data structure becomes more complex
Solution Approach 1:
The patent merges environment customization information directly into the video content item by embedding customization tracks within the existing video data structure. This combination allows the environment data to be distributed together with the video content through standard channels without requiring separate transmission or additional storage infrastructure, simplifying distribution while organizing complexity within a unified data structure.
Solution Approach 2:
The embedded environment customization tracks use a universal data structure that can accommodate multiple types of environment information (visual changes, audio modifications, interaction parameters) within a single standardized format. This multi-functional approach allows diverse environment customizations to be handled through a common data structure, reducing the need for multiple specialized structures and simplifying the overall system architecture.

AI summary
Some implementations disclosed herein enable customization of an XR environment for time-based content (e.g., a video) that is presented therein. This may involve altering or otherwise customizing an XR environment in which a video content item is viewed based on metadata stored in the video content item. The metadata may provide one or more additional timed tracks (or other synchronization data) that the device interprets to customize the environment during playback. For example, a player on the device may play image track content of a video while interpreting an environment customization track to send messages at defined playback times to the device's operating system or other component that provides views of the environment to alter or customize that viewing environment during that playback. Such messages may be directed to particular objects or actions that are exposed for video content item control by the environment or software that provides the environment.
