Dynamic Self-Area Warning Control for Obstacle-Aware Immersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing apparatuses, such as head-mounted displays, struggle to balance immersive experiences with safety by accurately determining and warning users of potential collisions with real-world obstacles, leading to either unnecessary warnings or missed alerts.
Innovation Solution
An information processing apparatus that adjusts a self-area based on user movement, using external cameras and sensors to detect obstacles and provide warnings only when necessary, thereby enhancing user safety while maintaining immersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the boundary area is set wider to improve safety, then more obstacles are detected, but unnecessary warnings increase and immersive experience deteriorates
Solution Approach 1:
The self-area boundary is dynamically adjusted based on user movement state. When the user is stationary, a wider boundary provides comprehensive obstacle detection. When the user moves quickly, the boundary contracts to reduce unnecessary warnings, maintaining both safety and immersive experience across different operational conditions.
Solution Approach 2:
The system changes the parameter of boundary area size based on movement speed. By monitoring user movement and adjusting the boundary area parameter accordingly, the system optimizes the balance between safety monitoring and user experience, preventing both missed detections and excessive warnings.
2Ease of operation
If the boundary area is set narrower to improve immersive experience, then unnecessary warnings decrease, but safety coverage is reduced
Solution Approach 1:
The boundary dynamically expands when the user is stationary to ensure comprehensive safety coverage, and contracts when moving to preserve immersive experience. This dynamic adjustment resolves the contradiction between safety coverage and user experience across different activity states.
Solution Approach 2:
The system adjusts the boundary area parameter based on movement speed measurements. By changing this parameter dynamically, the system achieves both wide coverage when needed for safety and narrow coverage when needed for immersive experience.
3Device complexity
If the boundary is fixed to simplify system complexity, then device complexity is reduced, but adaptability to changing environments deteriorates
Solution Approach 1:
Rather than implementing a complex fixed boundary system with multiple adjustment mechanisms, the system uses dynamic adjustment based on simple movement detection. This approach maintains relatively simple device architecture while achieving high adaptability to changing environmental conditions and user behaviors.
