Spatial Audio Processing for Immersive VR Sound
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual reality (VR) and augmented reality (AR) technologies fail to provide immersive sound experiences as they often separate virtual and real sound sources, leading to reduced realism and lack of spatial sound adaptation based on user orientation.
Innovation Solution
A method and apparatus that process sound effects by obtaining relative orientation information between a user's electronic device and sound source objects in a virtual environment, applying sound effect processing algorithms to generate and provide spatially accurate sound signals, enhancing the immersive experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sound is reproduced only through the AR device using external playback, then the device complexity is reduced, but the immersion and realism of the sound experience deteriorates
Solution Approach 1:
The patent merges virtual sound sources and real physical sound sources into a unified sound reproduction system. The wearable device integrates both virtual audio output (through headphones/speakers) and real audio capture (through microphones), processing them together to create a cohesive immersive experience that maintains realism while using a single device.
Solution Approach 2:
The patent introduces an intermediary processing system that captures real-world sounds through microphones, processes them along with virtual sound sources, and outputs the combined result through audio output units. This intermediary processing layer reconciles the simplicity of external playback with the realism of integrated sound reproduction.
2Device complexity
If sound is reproduced only through the AR device without spatial processing, then the processing complexity is reduced, but the immersive sound experience deteriorates
Solution Approach 1:
The patent implements dynamic spatial sound processing that adapts to the user's movement and orientation. The system continuously tracks the user's position and adjusts the sound field accordingly, making the audio experience dynamic and responsive to user actions rather than static.
Solution Approach 2:
The patent employs feedback mechanisms where the system continuously monitors user position, movement, and orientation through sensors, and uses this information to adjust the spatial sound reproduction in real-time. This closed-loop feedback ensures the sound experience remains synchronized with the user's physical state.
3Ease of operation
If virtual and real sound sources are separated, then the ease of operation is improved, but the overall immersion and user experience deteriorates
Solution Approach 1:
The patent merges virtual and real sound sources into a unified processing framework. Both types of sound sources are captured, processed, and reproduced together through the same audio output units, creating a seamless immersive experience while maintaining simple operation through automated integration.
Data Source
AI summary
A method for processing a sound effect is provided. The method includes obtaining relative orientation information of a first electronic device worn by a first user relative to at least one sound source object in a preset virtual environment, obtaining a processed sound source signal by performing sound effect processing on a sound source signal of the at least one sound source object based on the relative orientation information, and providing the processed sound source signal to the first user through the first electronic device.
