Video Communication Display Positioning for Realistic Presence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video communication systems fail to provide a realistic sense of presence as if the partner is in one's sight, leading to unnatural viewing experiences due to improper display sizing and positioning.
Innovation Solution
The system adjusts display ranges and positions based on physical size and installation position of displays, using camera and image analysis to calculate and ensure the partner's face is displayed at an appropriate height, simulating a virtual standing position, thereby providing a life-size and realistic view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the partner's video is displayed at a large size to enhance realism, then the sense of presence is improved, but the display position may become inappropriate (e.g., face too high or too low)
Solution Approach 1:
The display range is dynamically adjusted based on the detected face position and distance. The system continuously monitors the partner's face location in the video stream and automatically modifies the display parameters to maintain the face at an appropriate vertical position (e.g., eye level) while preserving the desired display size for realism.
Solution Approach 2:
The system changes display parameters (position, size, scaling) based on calculated distance and face position data. By adjusting these parameters dynamically, the system achieves both large display size for realism and correct positioning, resolving the contradiction between these two requirements.
2Area of stationary object
If the display range is adjusted to show the partner's full body, then completeness of view is improved, but the face may be displayed at an unnatural height
Solution Approach 1:
The system applies different quality requirements to different parts of the display. The face region is given priority for correct positioning at eye level, while other parts of the body can be displayed at relative positions. This local quality approach allows the face to be correctly positioned even when showing the full body.
Solution Approach 2:
The system transitions from displaying the entire body at uniform scale to a dimensionally adjusted view where the face is positioned at the correct vertical level while the body extends above and below. This may involve cropping, scaling, or composite display techniques to achieve proper face positioning while maintaining body completeness.
3Manufacturing precision
If facial recognition is used to guide user position, then viewing position accuracy is improved, but the system complexity increases
Solution Approach 1:
The system performs self-adjustment by automatically detecting the face position and distance, then autonomously modifying the display parameters without requiring external intervention or complex user guidance systems. This self-service approach reduces system complexity while maintaining high positioning accuracy.
Solution Approach 2:
The system uses feedback from face detection and distance calculation to continuously adjust display parameters. This closed-loop feedback mechanism enables accurate positioning without requiring complex pre-programming or manual configuration, simplifying the overall system while achieving high precision.
