Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable devices do not adapt spatial audio processing based on the current listening mode, leading to a suboptimal user experience as users must manually adjust settings to achieve desired listening conditions.
Innovation Solution
A computer-implemented method and apparatus for wearable devices that dynamically detect the activated listening mode and adjust spatial audio processing settings accordingly, including applying different settings for active noise cancellation and transparency listening modes, and optionally adjusting based on environmental acoustic properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If spatial audio processing settings are kept fixed across all listening modes, then device complexity is reduced, but listening experience quality deteriorates
Solution Approach 1:
The patent implements dynamic spatial audio processing settings that automatically adapt to the current listening mode. The system transitions from static, fixed settings to dynamic, mode-dependent settings. When the listening mode changes (e.g., from noise cancellation to transparency mode), the spatial audio rendering algorithm automatically adjusts its parameters without requiring manual user intervention, thereby maintaining high listening experience quality while managing device complexity through automated adaptation.
2Ease of manufacture
If spatial audio processing is manually adjusted for each listening mode, then listening experience quality is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements a self-service mechanism where the spatial audio processing system automatically detects the current listening mode and adjusts its own settings accordingly. The system monitors listening mode changes and autonomously reconfigures spatial audio parameters without requiring user intervention. This eliminates the need for manual adjustment while maintaining optimized listening experience quality across different listening modes.
Solution Approach 2:
The system employs feedback mechanisms by continuously monitoring the current listening mode state and using this information to automatically adjust spatial audio processing settings. The listening mode detection provides feedback to the spatial audio rendering algorithm, which then adapts its parameters in real-time to match the active listening mode, ensuring optimal performance without manual user input.
3Ease of manufacture
If different spatial audio processing settings are applied for each listening mode, then listening experience quality is improved, but device complexity increases
Solution Approach 1:
The patent manages device complexity by implementing a dynamic configuration system where spatial audio processing settings are automatically selected based on the current listening mode. Rather than requiring separate manual configurations for each mode, the system dynamically adapts settings through automated detection and adjustment, thereby supporting multiple optimized configurations without proportionally increasing operational complexity.
