HMD Volume Adjustment Using Ear-Entrance Noise Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of head-mounted display devices face difficulty in adjusting volume in noisy environments, as existing methods are cumbersome or inconvenient, especially when playing games or watching videos.
Innovation Solution
A method and apparatus that automatically adjusts the volume of head-mounted display devices by picking up sound signals at the ear entrance, extracting environment sound signals, determining an output volume target value based on these signals, and adjusting the volume accordingly using a preset relational expression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual volume adjustment methods are used (exiting to UI or pressing volume button), then volume control is achieved, but operation convenience deteriorates especially when playing games or watching videos
Solution Approach 1:
The system automatically detects environmental noise levels and adjusts volume without user intervention. The noise detection module continuously monitors the environment and the volume adjustment module autonomously modifies output based on detected noise, eliminating the need for manual volume control operations.
Solution Approach 2:
The system implements a feedback loop where the noise detection module continuously monitors environmental sound levels and feeds this information to the volume adjustment module, which then modifies the volume output accordingly. This closed-loop control enables automatic adaptation to changing noise conditions without user input.
2Reliability
If volume is increased to overcome environmental noise, then sound clarity improves, but device output power increases consuming more energy
Solution Approach 1:
The system dynamically adjusts volume based on real-time environmental noise conditions rather than maintaining a fixed high volume. The noise detection module continuously monitors noise levels and the volume adjustment module adapts the output accordingly, ensuring sound clarity is maintained at the minimum necessary power level.
Solution Approach 2:
The system changes the volume parameter dynamically based on environmental conditions. The noise detection module measures environmental sound levels and the volume adjustment module modifies the output volume parameter accordingly, optimizing the balance between sound clarity and energy consumption.
3Ease of operation
If automatic volume adjustment based on environmental noise is implemented, then ease of operation improves, but device complexity increases due to additional modules
Solution Approach 1:
The existing audio processing components are made multi-functional by adding noise detection capabilities and automatic volume adjustment logic. The same processing pipeline that handles audio playback is extended to also analyze environmental noise and control volume, reducing the need for completely separate dedicated hardware modules.
