Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio apparatuses provide interactive audio that is unrealistic due to its lack of consideration for the user's position, speaker position, and the space characteristics of the main audio, resulting in poor liveness and immersion.
Innovation Solution
An audio apparatus and method that processes audio signals by panning interactive audio based on user and sound source positions, and mixing it with main audio to create a 3D space effect, utilizing position information and space characteristics to enhance the realism and liveness of the interactive audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interactive audio is provided regardless of user position and space characteristics, then the audio apparatus structure remains simple, but the liveness and realism of interactive audio deteriorates
Solution Approach 1:
The patent applies dynamics by making the interactive audio parameters (position, panning, spatial characteristics) variable and adaptive rather than fixed. The system dynamically adjusts audio parameters based on real-time detection of user position and space characteristics, transforming the static audio output into a dynamic one that responds to changing conditions, thereby improving liveness without requiring a completely complex system architecture
Solution Approach 2:
The patent changes audio parameters such as position, panning coefficients, and spatial characteristics based on detected user position and space characteristics. By modifying these parameters dynamically, the system achieves more realistic interactive audio while maintaining a relatively simple processing architecture, resolving the contradiction between reliability and device complexity
2Reliability
If interactive audio is provided without considering space characteristics, then the audio processing is simpler, but the realism and immersion of the audio experience deteriorates
Solution Approach 1:
The patent implements feedback by detecting space characteristics and user position, then using this information to adjust interactive audio parameters. The system continuously monitors the audio environment and adapts the audio output accordingly, creating a closed-loop system that improves realism while managing processing complexity through intelligent feedback mechanisms
Solution Approach 2:
The patent applies preliminary action by pre-processing and storing space characteristics and audio parameter mappings before actual audio playback. The system pre-calculates and stores appropriate audio parameters for different space types and user positions, enabling rapid retrieval and application during actual use, thus improving realism without proportionally increasing real-time processing complexity
3Reliability
If interactive audio is provided without considering user position, then the system operation is simpler, but the liveness and engagement of the user deteriorates
Solution Approach 1:
The patent applies self-service by having the system automatically detect user position and space characteristics without requiring explicit user input or configuration. The system serves itself by autonomously gathering environmental information and adjusting audio parameters accordingly, improving liveness while maintaining ease of operation as users simply need to be present in the detected space
Solution Approach 2:
The patent makes the audio apparatus universal by enabling it to automatically adapt to different user positions and space characteristics through a single unified processing system. The same basic architecture handles multiple scenarios (different positions, spaces, and configurations) without requiring separate operation modes or complex user interactions, thus improving liveness while preserving ease of operation
