Virtual Meeting Spatial Audio for Parallel Side Conversations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional virtual meetings lack the ability to simulate an in-person experience, leading to reduced participant engagement and productivity due to participants being in distinct locations, which diminishes interpersonal interactions.
Innovation Solution
A virtual meeting system that adjusts audio parameters such as volume and balance based on the relative location of participants within a virtual space using trigonometric functions, allowing participants to select their virtual location and enabling parallel meetings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional virtual meetings place participants in distinct locations, then participants can communicate remotely, but participant engagement and interpersonal interactions are reduced
Solution Approach 1:
The patent transitions from conventional 2D video conferencing to a 3D virtual environment where participants are represented by avatars in a shared virtual space. This dimensional enhancement allows participants to perceive spatial relationships, distances, and directions between other participants, creating a more immersive experience that mimics in-person interactions while maintaining remote communication capabilities
Solution Approach 2:
The patent dynamically adjusts audio parameters (volume, balance, spatial position) based on the virtual locations and distances between participants. By changing these acoustic parameters in real-time according to spatial relationships, the system creates a realistic auditory experience that enhances engagement and makes remote participants feel present in the same virtual room
2Ease of operation
If conventional virtual meetings provide basic video capabilities, then participants can see each other remotely, but the experience lacks immersion and feels like phone conversation rather than in-person meeting
Solution Approach 1:
The patent enhances basic video communication by adding a third dimension through 3D spatial positioning of avatars. Participants are no longer confined to flat video grids but are placed in a volumetric virtual environment where they can move, gesture, and interact spatially, transforming the experience from phone-like conversation to immersive in-person simulation
Solution Approach 2:
The patent replaces conventional video/audio transmission with a spatial audio system that uses trigonometric calculations to determine sound direction, distance, and volume based on avatar positions. This substitution of basic communication mechanics with spatial-aware audio processing creates a more natural and immersive listening experience that adapts to participant movements and orientations
3Adaptability or versatility
If audio parameters are adjusted based on virtual location using trigonometric functions, then immersive audio simulation is achieved, but device complexity increases
Solution Approach 1:
The system automatically calculates spatial relationships and adjusts audio parameters without requiring manual configuration. The trigonometric functions continuously compute distances and angles between avatars based on their positions in the virtual environment, and the audio system self-adjusts volume, balance, and spatial placement accordingly, eliminating the need for user intervention while maintaining high adaptability
4Ease of operation
If participants are placed in distinct virtual locations, then remote connection is maintained, but interpersonal interactions are diminished
Solution Approach 1:
The patent introduces avatars as intermediaries that represent participants in the virtual environment. These digital representations convey not only visual information but also spatial positioning, body language, and proximity cues that facilitate natural interpersonal interactions. The avatars mediate between the physical locations of remote participants and the virtual shared space, preserving interaction quality while maintaining remote connection

AI summary
A virtual meeting system is discussed herein. An online meeting application can provide a parallel virtual meeting between or among two or more participants of a main virtual meeting. The parallel virtual meeting permits two or more participants of the main virtual meeting to have a “smaller-sized” meeting in parallel with the main virtual speaker or presentation while still participating in the main virtual meeting. Therefore, the participants of the parallel virtual meeting do not have to connect via another device or application and can avoid disrupting the main virtual meeting. The parallel virtual meeting can permit two separate meetings, such as one meeting with all participants and one meeting with a subset of all the participants.
