Mirrored Video Feed Orientation for Gesture Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current videoconferencing systems fail to accurately represent the direction of gaze and gestures among participants in gallery views, leading to confusion and misinterpretation of interactions, as the orientation of video feeds does not align with the user's perspective, affecting social dynamics and interactive experiences.
Innovation Solution
The system automatically displays video feeds in a mirrored fashion for interacting participants, ensuring that gestures and gaze directions are perceived correctly by all users, while non-interacting participants see unmirrored feeds to maintain a natural interaction environment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If video feeds are displayed in standard orientation, then the view matches how others see the participant, but gestures and gaze directions become misaligned with the user's perspective
Solution Approach 1:
The patent applies different display orientations to different participants based on their interaction status. Interacting participants have their video feeds mirrored to align gestures and gaze with the user's perspective, while non-interacting participants remain in standard orientation. This local differentiation resolves the contradiction by applying mirroring only where it benefits gesture accuracy.
Solution Approach 2:
The patent inverts the conventional approach by mirroring video feeds of interacting participants instead of displaying them in standard orientation. This inversion aligns the visual representation with the user's physical perspective, making gestures and gaze directions accurate while maintaining awareness of others through visual cues.
2Measurement precision
If all video feeds are mirrored, then gestures and gaze directions align with user perspective, but it becomes difficult to distinguish interacting from non-interacting participants
Solution Approach 1:
The patent applies mirroring selectively only to interacting participants rather than all participants. This creates a visual distinction where mirrored feeds indicate active interaction while unmirrored feeds indicate passive observation, preserving interaction status information while achieving gesture alignment for those who need it.
Solution Approach 2:
The patent segments participants into two groups: interacting participants whose feeds are mirrored, and non-interacting participants whose feeds remain unmirrored. This segmentation allows the system to provide gesture alignment benefits to active participants while maintaining visual distinction and information about interaction status across all participants.
3Measurement precision
If video feeds are rearranged in mirrored fashion, then interaction dynamics are preserved accurately, but the display complexity increases
Solution Approach 1:
The patent segments the video feed arrangement into two distinct groups: interacting participants arranged in mirrored fashion and non-interacting participants in standard arrangement. This segmentation enables accurate interaction dynamics for active participants while keeping the overall system manageable through clear visual separation and automated detection of interaction status.

AI summary
A virtual space view is provided in an online meeting user interface associated with a videoconferencing system that is changeable by gestures of meeting participants. The virtual space view displays avatars or video feeds of the meeting participants on their respective participant computers. The videoconferencing system captures video feeds of all meeting participants, including meeting participants being displayed as avatars. Software of the videoconferencing system recognizes a specific gesture of a meeting participant. The specific gesture is associated with a predefined directional movement of the meeting participant's avatar or video feed within the virtual space view during the online meeting, and the predefined directional movement is requested by the meeting participant via the specific gesture. The specific gesture of the meeting participant is a physical body gesture of the meeting participant which is captured in the video feed of the meeting participant. The videoconferencing system automatically repositions the video feed of the meeting participant who made the specific gesture within the virtual space view during the online meeting in accordance with the associated predefined directional movement.
