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

VSEngineering 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

Engineering Contradiction:
Improveuser convenienceVSAvoidtracking sensitivity adaptation
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

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.

Inventive Principle:
Principle #15Dynamics

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.

Inventive Principle:
Principle #35Parameter changes

2Device complexity

If fixed tracking sensitivity is used, then device complexity is reduced, but user experience in varied environments deteriorates

Engineering Contradiction:
Improvetracking control mechanismVSAvoidenvironmental adaptation
Core Design Contradiction:
Device complexityVSAdaptability or versatility

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #23Feedback

3Device complexity

If tracking sensitivity is adjusted for all directions uniformly, then device complexity is reduced, but interaction quality in specific directions suffers

Engineering Contradiction:
Improvetracking control mechanismVSAvoidinteraction quality
Core Design Contradiction:
Device complexityVSEase of operation

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.

Inventive Principle:
Principle #3Local quality
