Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video teleconferencing systems fail to create an immersive collaboration experience due to lack of spatial and visual cues, inadequate synchronization of conference environments, and inaccurate audio cueing, leading to a sense of remoteness among participants.
Innovation Solution
An advanced video teleconferencing system with carefully designed table and room geometry, supplementary displays showing mirrored imagery, networked environmental control, AutoDirector with keyword and gesture recognition, and audio reflection from the display or beam splitter to enhance the sense of a shared space and accurate audio sourcing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional video teleconferencing systems are used, then basic communication functionality is provided, but spatial and visual cues are lacking causing a sense of remoteness among participants
Solution Approach 1:
A beam splitter is introduced as an intermediary optical element between the display and participants. The beam splitter reflects audio towards participants while allowing video imagery to pass through, creating accurate audio cueing that matches the visual display location and eliminating the sense of remoteness
Solution Approach 2:
Supplementary displays create mirrored copies of the main display content and are positioned to show imagery in a mirrored manner. This copying approach provides additional spatial references and visual cues that reinforce the sense of a shared physical space among remote participants
2Device complexity
If conventional display and audio routing is used, then simple system configuration is maintained, but audio cueing is inaccurate causing remote participant voices to emanate from locations other than their displayed images
Solution Approach 1:
The beam splitter serves as an optical intermediary that physically routes audio signals to emanate from the correct spatial location corresponding to each remote participant's video image, achieving accurate audio cueing without complex software configuration
Solution Approach 2:
The patent replaces conventional speaker-based audio routing with an optical-mechanical system using a beam splitter to physically direct audio. This substitution achieves precise spatial audio cueing through optical paths rather than electronic signal routing
3Loss of information
If supplementary displays are added to enhance spatial perception, then visual cues are improved, but system complexity increases
Solution Approach 1:
Supplementary displays are configured to show mirrored copies of the main display content. This copying strategy enhances spatial perception by providing additional visual references while maintaining a standardized configuration that simplifies system integration
Solution Approach 2:
The supplementary displays are positioned and configured to provide localized visual information that complements the main display. Each display serves a specific spatial function, creating a distributed visual field that enhances overall spatial perception without requiring complex centralized control
