Video Conference System Dynamic Display Adaptation for Disability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video conferencing systems often fail to accommodate participants with disabilities, as they rely on fixed display rules that do not account for varying needs such as hearing, vision, or speech impairments, potentially hindering their ability to fully participate.
Innovation Solution
A system that analyzes participant characteristics, such as voice, gestures, and facial expressions to dynamically adjust video conference settings, including display size and format, to better facilitate participation for individuals with disabilities, such as enlarging the active speaker's image for the partially blind or providing lip reading assistance for the hard of hearing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed display rules are used for video conferencing, then the system is simple and easy to operate, but it cannot accommodate participants with disabilities
Solution Approach 1:
The video conference system dynamically adjusts display parameters such as window size, position, and visibility based on real-time detection of participant disabilities. The system transitions from static fixed rules to dynamic adaptive configuration, modifying the display layout according to detected needs of participants with hearing, vision, or speech impairments
Solution Approach 2:
The system automatically detects participant disabilities through analysis of video feeds and audio characteristics, then self-configures the display settings without requiring manual input from participants. The system serves itself by identifying needs and implementing accommodations autonomously
2Ease of operation
If automatic disability detection and dynamic configuration is implemented, then participation of individuals with disabilities is enhanced, but the system complexity increases
Solution Approach 1:
The system replaces manual configuration operations with automated detection and adjustment mechanisms. Instead of requiring participants to manually adjust settings, the system uses computer vision and audio analysis to automatically detect disabilities and configure optimal display parameters
Solution Approach 2:
The system changes multiple display parameters simultaneously including window size, position, visibility, and layout configuration based on detected disability types. Parameters such as the size of active speaker windows and positioning of participant video feeds are dynamically adjusted to accommodate specific needs
3Measurement precision
If multiple active speakers are displayed for hard of hearing participants, then lip reading capability is improved, but the display layout complexity increases
Solution Approach 1:
The display is segmented into functional zones with different purposes: enlarged active speaker windows for lip reading, smaller background participant windows, and text caption areas. The segmentation allows optimization of specific display regions for particular functions while maintaining overall system coherence
4Illumination intensity
If the active speaker image is enlarged for partially blind participants, then visibility is improved, but other participants may be less visible
Solution Approach 1:
The system uses spatial arrangement in multiple display dimensions to resolve the visibility conflict. Enlarged active speaker windows are positioned in primary viewing areas while smaller participant windows are arranged in background or peripheral areas, ensuring both prominence of active speakers and visibility of other participants through strategic spatial distribution

AI summary
Video conferences are a common occurrence in many business, academic, and other settings. Systems and methods provided herein enable a participant of a video conference, who has an impairment or disability, such as to hearing, speech, or vision, to have that impairment or disability mitigated by automatically detecting and implementing mitigating actions to the participants local device and/or the devices of the remote participants.
