HMD Tracking Sensitivity Adaptation for Dynamic Environments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Head-mounted displays (HMDs) lack the ability to dynamically adjust tracking sensitivity based on the user's environment and content output, limiting their functionality and user convenience.
Innovation Solution
Incorporating a camera, microphone, and location information module to determine the user's environment and adjust tracking sensitivity accordingly, allowing for real-time recognition of external events and content-specific adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If body motion tracking mechanism is used for input, then user convenience is improved, but tracking sensitivity cannot be adjusted according to use environment
Solution Approach 1:
The system dynamically adjusts tracking sensitivity based on detected use environments (e.g., walking, driving, stationary) and content types. The controller modifies tracking parameters in real-time according to the current context, making the body motion tracking mechanism adaptable to different situations while maintaining ease of operation.
Solution Approach 2:
The system changes tracking sensitivity parameters according to the detected use environment and content being displayed. Different environments (walking, driving, stationary) and content types trigger different tracking sensitivity levels, allowing the system to optimize performance for each specific context without requiring manual user adjustment.
2Device complexity
If fixed tracking sensitivity is used, then device complexity is reduced, but user experience in varied environments deteriorates
Solution Approach 1:
The system automatically detects the use environment (through sensors detecting motion patterns, location changes, etc.) and self-adjusts tracking sensitivity without user intervention. The controller autonomously selects appropriate tracking parameters based on the detected context, eliminating the need for complex manual adjustment mechanisms while improving environmental adaptability.
Solution Approach 2:
The system uses sensor feedback to continuously monitor the use environment and adjusts tracking sensitivity accordingly. The controller receives input from motion sensors, location modules, and other sensors to determine the current context, then modifies tracking parameters in real-time to optimize user experience for that specific environment.
3Device complexity
If tracking sensitivity is adjusted for all directions uniformly, then device complexity is reduced, but interaction quality in specific directions suffers
Solution Approach 1:
The system applies different tracking sensitivity levels to different spatial directions based on the detected use environment and content type. For example, horizontal tracking may be adjusted differently from vertical tracking, or tracking sensitivity may vary for directions relevant to the current content being displayed, optimizing interaction quality for each direction independently.
