Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If only visual integration is implemented in augmented reality, then image fusion capability is achieved, but auditory integration capability is lacking

Engineering Contradiction:
Improveintegration capabilityVSAvoidauditory dimension
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent combines real audio signals from the physical environment with virtual audio signals from the augmented reality scene through sound mixing processing. The mixing module merges these two audio sources into a unified audio output, enabling simultaneous presentation of both real and virtual auditory information to the user.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The audio processing system is designed to handle multiple audio sources and mixing modes universally. It can process real audio signals, virtual audio signals, and their combinations through different mixing strategies (additive mixing, multiplicative mixing, or selective mixing), making the system adaptable to various augmented reality scenarios.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple sound mixing modes are provided, then user customization and scene adaptability are improved, but system complexity increases

Engineering Contradiction:
Improvesound mixing mode selectionVSAvoidprocessing system
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system provides dynamic sound mixing modes that can be switched based on different augmented reality scenes and user preferences. The mixing module can adaptively change between additive mixing, multiplicative mixing, and selective mixing strategies, allowing the system to respond dynamically to different operational contexts without requiring separate hardware for each mode.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different sound mixing modes are achieved by changing the processing parameters and algorithms within the mixing module. By adjusting mixing coefficients, signal combination methods, and gain parameters, the system can transition between different mixing strategies using the same hardware infrastructure, thereby reducing overall system complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If real and virtual audio signals are mixed, then immersive experience is enhanced, but audio processing complexity increases

Engineering Contradiction:
Improveimmersive experienceVSAvoidaudio processing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The audio processing system segments the audio signal stream into distinct real audio signals and virtual audio signals. This segmentation allows independent processing of each signal type before combining them, enabling precise control over the mixing process while maintaining manageable complexity through modular signal handling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The mixing module acts as an intermediary component that receives both real and virtual audio signals, processes them through selected mixing strategies, and produces the final mixed audio output. This intermediary structure simplifies the overall system architecture by centralizing the complex mixing operations in a dedicated module rather than distributing complexity throughout the entire audio processing chain.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

This application provides an audio processing method performed by a computer device. The method includes: obtaining a real audio signal from a real environment and a virtual audio signal from a virtual environment in an augmented reality scene; selecting one sound mixing mode from a plurality of sound mixing modes configured for the augmented reality scene as a target sound mixing mode; performing sound mixing processing on the real audio signal and the virtual audio signal according to the target sound mixing mode to obtain a sound-mixed signal; and outputting the sound-mixed signal via a speaker of the computer device. In this way, integration of sounds in an augmented reality scene is realized in an auditory dimension, thereby enriching an integration capability in the augmented reality scene, and improving an overall immersed sense of a user in the augmented reality scene.
