Display Control for Gesture-Responsive Video Call UI Scaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in balancing the display of video call user interfaces (UI) with content sharing, as large UIs obstruct content viewing while small UIs diminish the video call experience.
Innovation Solution
A display apparatus that adjusts the size of the video call UI based on user gestures and voice inputs, using a processor to control the display to enlarge, reduce, or provide visual feedback when predetermined conditions are met, and considers privacy levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the video call UI is displayed to be large, then the video call interaction quality is improved, but the content viewing is obstructed
Solution Approach 1:
The video call UI size is made dynamic rather than static. The processor automatically adjusts the UI size based on real-time detection of user gestures (e.g., hand waving) and voice commands. This allows the UI to expand when interaction is needed and shrink when content viewing is prioritized, resolving the contradiction between interaction quality and content viewing area.
2Area of stationary object
If the video call UI is displayed to be small, then the content viewing area is preserved, but the video call interaction quality deteriorates
Solution Approach 1:
The system implements feedback mechanisms by detecting user gestures and voice inputs in real-time. When the processor detects specific gestures (e.g., hand waving) or voice commands, it triggers UI size adjustments. This feedback loop ensures the UI size adapts to user needs, maintaining interaction quality while preserving content viewing area when not in use.
3Adaptability or versatility
If the video call UI size is dynamically adjusted, then the user experience is enhanced, but the device complexity increases
Solution Approach 1:
The system performs self-service by automatically detecting user intent through gestures and voice, then autonomously adjusting the UI size without requiring manual user intervention. The processor analyzes detected inputs and makes decisions about UI scaling, reducing the need for complex user interfaces and manual controls while enhancing adaptability.

AI summary
A display apparatus includes a communication interface configured to communicate with another display apparatus, a display configured to display contents being shared with the other display apparatus and a video call user interface (UI) for a video call with a user of the other display apparatus, and a processor, in response to at least one of a gesture and a voice of the user included in video call data received from the other display apparatus satisfying a predetermined condition, configured to control the display to change a size of the video call UI displayed on the display.
