Spatial Audio Sector Rendering for Immersive Call Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current immersive audio rendering during calls fails to differentiate between spatial audio sources within the call and those from the surrounding environment, leading to a reduction in the immersive experience due to limitations in 3D or 6DoF movement and inability to distinguish between normal and spatial participants.
Innovation Solution
The method involves rendering spatial audio sources within specific sectors that can be modified based on user activity, such as head movement, allowing differentiation between call audio and environmental sounds by adjusting the width and positioning of these sectors, while keeping participants in a fixed position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spatial audio sources are rendered in a call to provide immersive audio experience, then the realism of the call is improved, but the ability to differentiate between call audio and environmental sounds deteriorates
Solution Approach 1:
The audio space is segmented into multiple sectors, each associated with specific participants or audio sources. This segmentation allows the system to apply different rendering characteristics to different audio sources, enabling differentiation between call audio and environmental sounds while maintaining immersive experience. Each sector can be independently controlled and modified based on user activity.
2Adaptability or versatility
If the audio rendering is modified in response to user activity to enhance interactivity, then the adaptability is improved, but the complexity of the rendering system deteriorates
Solution Approach 1:
The audio rendering system is made dynamic by allowing real-time modification of sector characteristics in response to user activity such as head movement. The system can adjust audio parameters like spatial position, width, and positioning of sectors dynamically, creating an adaptive immersive experience that responds to user interactions without requiring complete system redesign.

AI summary
Disclosed is a method comprising: rendering a call, for a user, wherein the call comprises a first sector and a second sector, wherein the first sector comprises a first participant in the call and at least one spatial audio source associated with the first participant, and the second sector comprises a second participant and at least one spatial audio source associated with the second participant, detecting an activity of the user, and as a response to the activity of the user, providing an audible change in the rendering of the call by modifying at least one of the first and the second sector.
