Spatial Audio Conversation Discovery in Teleconference Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current teleconferencing systems prevent simultaneous conversations among participants due to equal audio distribution, limiting interaction and side conversations, and lack features available in in-person conferences.
Innovation Solution
Implement variable-volume audio based on user-controlled or system-controlled positioning in a virtual room, integrate supplemental data from social media, and analyze audio for insights like keywords and sentiment, allowing for spatial audio and enhanced conversation discovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If equal audio distribution is implemented for all participants, then all participants can hear all speakers, but simultaneous conversations become incomprehensible and direct interactions are limited
Solution Approach 1:
The patent applies local quality by providing different audio volumes to different participants based on their spatial position in the virtual room. Participants closer to a speaker receive amplified audio from that speaker, while participants farther away receive less audio. This creates localized audio zones that enable simultaneous conversations to be comprehensible to relevant participants without requiring equal distribution to everyone.
Solution Approach 2:
The patent introduces spatial positioning as a new dimension for audio distribution. Instead of uniform distribution across all participants, the system uses three-dimensional spatial coordinates to determine audio volume. Participants can move their interface elements closer to or farther from other participants to control audio reception, transforming the flat list of participants into a spatial arrangement that enables selective audio attention.
2Adaptability or versatility
If variable-volume audio based on spatial position is implemented, then multiple conversations can occur simultaneously, but the system complexity increases
Solution Approach 1:
The patent implements self-service by allowing participants to control their own audio reception through spatial positioning. Participants move their interface elements to desired locations in the virtual room, and the system automatically adjusts audio volumes based on these positions. This eliminates the need for manual audio mixing or complex control interfaces, reducing operational complexity while enabling versatile conversation capabilities.
Solution Approach 2:
The patent uses parameter changes by dynamically adjusting audio volume levels based on spatial position parameters. The system calculates the distance between participants' interface elements and applies volume attenuation accordingly. This mathematical approach to audio control is computationally efficient and avoids the complexity of traditional audio mixing equipment or manual control mechanisms.
3Ease of operation
If presenter audio is distributed to all participants while side conversations are excluded from presenter view, then presenter is not distracted, but side conversations are isolated from presenter
Solution Approach 1:
The patent applies segmentation by separating audio streams into different categories: presenter audio and side conversation audio. The system identifies which participants are presenting and which are engaged in side conversations, then distributes these audio streams differently. Presenters receive presenter audio with high volume and side conversation audio with reduced or blocked volume, while other participants receive both streams appropriately mixed for their spatial positions.

AI summary
Systems and methods for providing enhanced teleconferencing. An example method includes receiving audio streams from a plurality of client devices of participants of a teleconference; converting the audio streams for a first conversation within the teleconference into first text; converting the audio streams for a second conversation within the teleconference into a second text; analyzing the first text to identify one or more topics being discussed in the first conversation; analyzing the second text to identify one or more topics being discussed in the second conversation; and presenting, in a teleconference user interface, at least one of the one or more topics being discussed in the first conversation or the one or more topics being discussed in the second conversation.
