Video Conference Presenter Control via Gesture Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video conferencing systems lack effective methods for dynamically switching presenter control during a conference, limiting user engagement and participation, especially for users who are deaf or mute.
Innovation Solution
A system that detects predefined gestures, such as hand waves or sign language, and voice inputs to automatically switch the video streams in a user interface, promoting users who intend to be the current presenter to a prominent position, while maintaining others in secondary positions until they relinquish control or are overtaken.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual presenter switching is used in video conferencing, then control is simple and direct, but user engagement and participation are limited
Solution Approach 1:
The system automatically detects gestures and voice inputs to switch presenters without manual intervention. The video conferencing system serves itself by autonomously identifying user intent through gesture recognition and voice analysis, eliminating the need for users to manually request presenter status changes.
Solution Approach 2:
The patent replaces manual mechanical control (buttons, switches) with gesture-based and voice-based control mechanisms. Users wave their hands or speak to indicate presenter intent, substituting physical button-pressing actions with more natural, accessible gestures that can be performed by users with various abilities.
2Device complexity
If traditional video conferencing interfaces are used, then the system is simple, but accessibility for deaf or mute users is poor
Solution Approach 1:
The system incorporates multiple input modalities (gesture recognition, voice analysis, heuristic evaluation) to serve diverse user needs. By providing multiple ways to indicate presenter intent, the system becomes universally accessible to users with different abilities, including deaf or mute users who can use gestures instead of voice.
Solution Approach 2:
The system changes the control parameters from voice-only or button-press-based to include gesture-based control. By introducing new control parameters (hand waving motions, sign language gestures), the system expands accessibility options without fundamentally redesigning the entire video conferencing platform.
3Adaptability or versatility
If automatic presenter switching is implemented, then user engagement improves, but system complexity increases
Solution Approach 1:
The system implements partial automation by focusing on specific, high-impact features (gesture detection for presenter switching) rather than fully automating all video conferencing functions. This selective approach improves user engagement through automatic presenter switching while avoiding the complexity of comprehensive system automation.
Solution Approach 2:
The patent introduces heuristic analysis as an intermediary layer between gesture detection and presenter switching. The heuristic module evaluates multiple factors (gesture confidence, current presentation context, user roles) before making presenter switching decisions, mediating between raw sensor data and system actions to manage complexity.
4Ease of operation
If gesture recognition is added to detect presenter intent, then accessibility for deaf or mute users improves, but detection precision requirements increase
Solution Approach 1:
The system employs feedback mechanisms where detected gestures are analyzed through heuristic evaluation that considers multiple factors including gesture confidence levels, contextual information, and user patterns. This feedback loop allows the system to adjust detection sensitivity and make more accurate presenter intent determinations despite the inherent variability in gesture recognition.

AI summary
Embodiments generally relate to presenter control during a video conference. In one embodiment, a method includes providing a user interface of a video conference between at least a first user and a second user, where the user interface displays a first user video stream in a current presenter position and displays a second user video stream in a secondary presenter position. The method also includes detecting at least one gesture from the second user, where the detecting of the at least one gesture indicates that the second user intends to be a current presenter. The method also includes causing the user interface to display the second user video stream in the current presenter position and to display the first user video stream in the secondary presenter position in response to the detecting.
