Telepresence Gestural Interface Single Screen Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional teleconferencing systems require remote attendees to choose between viewing the presenter or the electronic presentation, often necessitating additional hardware and being cumbersome to navigate between the two, especially when trying to discuss slides or images.
Innovation Solution
A video telepresence system that integrates real-time video of the presenter within the electronic presentation on a single screen, using a gestural interface to control the presentation, allowing for seamless interaction and control without the need for dual screens or additional hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If remote attendees use dual screens to view both presenter and presentation, then viewing completeness is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges the presenter video feed and electronic presentation onto a single screen display. The system composites the presenter's video image with the presentation slides, allowing remote attendees to view both simultaneously on one screen rather than requiring dual screens. This is achieved by capturing the presenter's video, extracting the presentation content, and overlaying or positioning them together on the same display device.
Solution Approach 2:
The single screen display serves multiple functions: it displays the electronic presentation slides, overlays the presenter's video feed, and enables interaction through gestural interface. This multi-functional display eliminates the need for separate dedicated screens for presentations and video conferencing, reducing hardware complexity while maintaining complete viewing capability.
2Loss of information
If remote attendees use dual screens to view both presenter and presentation, then viewing completeness is improved, but ease of operation deteriorates
Solution Approach 1:
By combining the presenter video and presentation on a single screen, the system eliminates the need for attendees to manually switch between different display devices. The merged display presents both elements simultaneously in a unified interface, making operation simpler and more intuitive.
Solution Approach 2:
The system introduces a gestural interface as an intermediary mechanism that enables natural interaction with the merged display. Attendees can control the presentation navigation, highlight elements, and interact with both the video and presentation content through gestures, eliminating the need to physically switch screens or use complex control mechanisms.
3Measurement precision
If the presenter's video is fully opaque, then video clarity is improved, but presentation content visibility deteriorates
Solution Approach 1:
The system applies different transparency levels to different regions of the display. The presenter's video feed uses partial transparency (e.g., 50-70% opacity) rather than full opacity, allowing presentation content to show through in certain areas. This local quality adjustment enables simultaneous visibility of both the presenter and presentation content without requiring dual screens.
Solution Approach 2:
The presentation content is nested behind the semi-transparent video overlay. The video feed is positioned in front of the presentation slides with adjusted transparency, creating a layered composition where both elements are visible. This nesting approach allows the video to dominate visually while still permitting presentation content to be perceived through the transparent portions.

AI summary
Methods, systems and computer-readable storage mediums encoded with computer programs executed by one or more processors for providing a telepresence with gestural interface for remote collaboration are disclosed. An electronic presentation including a background object and a foreground object is received. A real-time video of a presenter is received over a network for display within the electronic presentation. A layered presentation is composited. The layered presentation including the background object composited behind the opaque representation of the presenter composited behind the foreground object composited behind the translucent representation of the presenter. The layered presentation is provided for rendering in real-time.
