Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of head-mounted audio devices face the challenge of needing to perform complex operations to activate or deactivate noise reduction and ambient functions as their state or situation changes, often requiring manual intervention and removal of the device.
Innovation Solution
An information processing device and method that automatically control audio output modes by recognizing user states through sensors and adjusting noise reduction and ambient functions dynamically, allowing seamless transitions without user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If noise reduction and ambient functions are selectively activated/deactivated according to user state changes, then audio listening suitability is improved, but operation complexity increases
Solution Approach 1:
The system automatically detects user state changes through sensors (accelerometer, gyroscope, microphone) and autonomously switches between noise reduction and ambient functions without requiring manual user intervention. The device serves itself by monitoring its own operational context and adjusting audio processing accordingly.
Solution Approach 2:
The audio processing mode dynamically adapts to changing user states. The system transitions between static modes (noise reduction or ambient) based on detected motion patterns, device removal events, and audio analysis, making the audio experience flexible and context-aware rather than fixed.
2Measurement precision
If manual activation/deactivation of audio functions is required for each state change, then function control precision is improved, but time consumption increases
Solution Approach 1:
The system performs preliminary detection of user state changes through continuous sensor monitoring (accelerometer, gyroscope) and audio analysis. By detecting motion patterns, device removal, or ambient sound changes in advance, the system proactively switches audio functions before the user needs to manually intervene, reducing response time while maintaining appropriate function selection.
Solution Approach 2:
The system continuously monitors sensor data (acceleration, rotation, audio input) and provides feedback loops that automatically trigger function switching. The feedback mechanism analyzes detected states and adjusts audio processing in real-time, eliminating the need for manual user decisions while maintaining precise function control aligned with actual usage context.
3Adaptability or versatility
If head mounted-type audio device is temporarily removed for state changes, then adaptability to user needs is improved, but convenience deteriorates
Solution Approach 1:
The device automatically detects when it has been removed from the user's head using sensors (accelerometer, gyroscope, proximity sensors) and autonomously switches to appropriate audio modes or notifies the user, eliminating the need for manual device removal and reattachment operations.
Solution Approach 2:
The audio processing system dynamically adapts to device wear state changes. When the device detects it has been removed or is about to be removed through sensor analysis, it automatically transitions between audio modes, maintaining adaptability to user needs while keeping the device in place and avoiding the inconvenience of repeated physical manipulation.
