3D Immersive Navigation via Gaze-Driven Metadata and Spatial Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality technologies fail to effectively facilitate user navigation and enhance user experience in 3D scenes, as existing navigation methods are complex and not adaptable to new environments, lacking intuitive guidance and relighting capabilities.
Innovation Solution
A 3D immersive method that determines a user's position and orientation in a virtual scene, using metadata to execute actions such as guiding the user to specific locations and modifying lighting to direct attention, thereby enhancing navigation and relighting, allowing for dynamic and context-aware interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional game-based navigation controls are used in virtual reality, then users can navigate through 3D scenes, but users spend significant time understanding and mastering these controls
Solution Approach 1:
The system automatically detects user intent by analyzing gaze direction and scene metadata, then autonomously executes navigation actions without requiring users to learn or input complex control commands. The navigation system serves itself by interpreting user attention and context to determine appropriate actions.
Solution Approach 2:
The patent replaces traditional mechanical control interfaces (buttons, joysticks, keyboard commands) with a cognitive-based interaction model that uses gaze tracking and contextual metadata to infer user intent and execute navigation automatically, substituting physical control mechanics with perceptual and contextual processing.
2Adaptability or versatility
If existing VR navigation systems provide contextual guidance, then users can be directed to destinations, but the systems lack ability to read user intent and provide personalized guidance
Solution Approach 1:
The system continuously monitors user gaze direction, head orientation, and scene context to gather feedback about user intent. This feedback loop allows the system to dynamically adjust navigation guidance based on real-time user behavior and preferences, creating adaptive personalized navigation experiences.
Solution Approach 2:
The system pre-processes scene metadata and potential navigation targets before user interaction, organizing information about destinations, pathways, and contextual relevance. This preliminary preparation enables rapid response to user intent without requiring complex real-time computation during navigation.
3Ease of operation
If visual navigation aids like arrows and icons are added to VR scenes, then users receive directional guidance, but the navigation complexity increases for 3D environments
Solution Approach 1:
The patent transitions navigation guidance from traditional 2D UI overlays (arrows, icons, menus) to 3D spatial indicators integrated into the virtual environment. Navigation cues are positioned and oriented in 3D space relative to user gaze and scene geometry, providing intuitive directional guidance that leverages the natural spatial understanding of VR users.
Solution Approach 2:
The system provides navigation guidance selectively at specific locations and moments based on user gaze and contextual relevance, rather than displaying comprehensive navigation information throughout the entire scene. This localized approach reduces visual clutter and complexity while maintaining effective guidance where needed.

AI summary
A position and an orientation of a user in a virtual 3D scene is determined (22), an action is executed (24) in the virtual 3D scene for the user in function of the position and orientation of the user with respect to a given place, and a result of the action is outputted (25). For at least one event in the scene consisting in a presence of at least one determined virtual content, metadata linking the event(s) and at least one place of the event(s) are obtained (21). A given event and the given place linked by those metadata are determined (241), in function of the above position and orientation and of a relationship between that event and a user profile of the user. The action regarding the determined given event and place is executed.
