Descriptive Audio Channel for Multimedia Conference Inclusivity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Participants in multimedia conferences who cannot observe visual content, such as those using audio-only devices or those who are visually impaired, struggle to comprehend state changes like slide changes or file uploads due to lack of information about visual events during the conference.
Innovation Solution
A system that identifies participants as 'descriptive audio participants' and provides them with audio cues indicating state changes in the conference, such as slide numbers or other meta-data, through a descriptive audio channel, ensuring they receive additional information about the conference events without overlapping with the main audio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a multimedia conference is conducted with visual content (slides, file uploads), then information is conveyed to participants, but participants using audio-only devices or who are visually impaired cannot comprehend state changes
Solution Approach 1:
The patent introduces a descriptive audio channel as an intermediary that translates visual state changes (slides, file uploads) into audio descriptions. This mediator converts information from one form (visual) to another (audio) without adding complexity to the core conferencing system, resolving the contradiction between information accessibility and system complexity.
Solution Approach 2:
The system changes the parameter of information delivery by providing alternative modalities (audio descriptions) for participants who cannot access visual content. This parameter change enables information accessibility for audio-only participants without requiring them to use different devices or complex accommodations.
2Loss of information
If audio cues are provided to describe visual changes, then comprehension is improved for audio-only participants, but the audio stream may become cluttered or overlap with main conference audio
Solution Approach 1:
The patent segments the audio output into distinct channels: the main conference audio stream and a separate descriptive audio channel. This segmentation allows state change descriptions to be delivered without interfering with the primary conference audio, eliminating the harmful overlap while maintaining comprehension for audio-only participants.
3Adaptability or versatility
If descriptive audio is provided to all participants, then inclusivity is improved, but bandwidth and processing requirements increase
Solution Approach 1:
The patent applies local quality by providing descriptive audio selectively only to participants who have indicated they are audio-only or have visual impairments, rather than to all participants. This targeted approach maintains inclusivity while minimizing bandwidth consumption and processing requirements by delivering additional audio data only where necessary.
Data Source
AI summary
A computer-implemented method of conducting a multimedia conference can include identifying a participant from a plurality of participants as a descriptive audio participant in the multimedia conference and detecting a state change during the multimedia conference. The method can include correlating the state change with an audio cue and outputting the audio cue to the descriptive audio participant.
