Spatial Audio Layout for More Immersive Online Meetings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual meetings lack engagement and productivity due to their inability to simulate an in-person experience, as participants are isolated in distinct locations, leading to reduced interpersonal interactions.
Innovation Solution
A virtual meeting system that uses trigonometric functions to adjust audio parameters such as volume and balance based on the virtual location of participants, allowing them to select their own location and enhancing the immersive experience by simulating a shared space, while also enabling features like parallel meetings and audio adjustments for hearing impairments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional virtual meetings place participants in distinct locations, then technical simplicity is maintained, but participant engagement and interpersonal interaction are reduced
Solution Approach 1:
The patent introduces a spatial dimension to virtual meetings by implementing a virtual meeting space with defined locations and distances. Participants are positioned at different virtual locations (e.g., around a virtual table) rather than being in distinct isolated locations. This spatial arrangement enables direction-aware audio processing where audio parameters change based on the relative positions and orientations of participants, creating an immersive experience that simulates in-person interactions while maintaining technical feasibility through software-based audio processing.
2Adaptability or versatility
If audio parameters are adjusted based on virtual location, then immersive experience is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical or hardware-based spatial audio systems with software-based audio processing. Instead of requiring specialized hardware to achieve direction-aware audio, the system uses trigonometric functions and audio parameter adjustments processed through software applications on standard devices. The server-side application calculates audio parameters based on virtual positions and transmits processed audio signals to client devices, which then render the spatial audio using standard audio output capabilities.
3Productivity
If participants occupy the same virtual space, then interpersonal interaction is enhanced, but audio clarity among multiple speakers may deteriorate
Solution Approach 1:
The patent applies local quality by adjusting audio parameters specifically for each participant based on their virtual location and orientation. When multiple participants are in the same virtual space, the system processes audio signals individually, applying direction-aware audio processing that enhances the speaker's voice based on the listener's relative position. This allows multiple speakers to coexist in the virtual space while maintaining audio clarity, as each participant receives optimized audio from speakers in their respective directions.

AI summary
A virtual meeting system is discussed herein. An online meeting application places participants in their own virtual location with a common virtual meeting space and adjusts the audio volume and balance on a listener's device to simulate the virtual location of the participant who is speaking. The application includes a trigonometric function to adjust the audio volume and balance based on the location of the listener relative to the speaker. The application can also permit the participants to select their own virtual locations upon entry to the virtual meeting, can assign a virtual location or adjust audio based on a participant's settings, or can allow for parallel meetings.
