Adaptive Shared Content Focus for Smaller Screens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Video conferencing tools face challenges in screen sharing when participants have displays of varying sizes, leading to illegibility of shared content on smaller screens, as the same amount of text is displayed smaller, making it unreadable or inefficient for viewers.
Innovation Solution
A computing device automatically adjusts shared content by determining the display size of remote devices, calculating a focus point and enlargement factor, and adjusting the content to ensure readability on smaller screens, maintaining the same element size as on the presenter's display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the entire screen is shared with all participants, then the presenter can display complete content, but participants with smaller screens cannot read the content legibly
Solution Approach 1:
The system dynamically adjusts the shared content display by detecting the receiver's screen size and automatically calculating appropriate focus areas and enlargement factors. This transforms the static screen sharing into a dynamic adaptive process where the content presentation automatically changes based on the receiver's device characteristics, eliminating the need for manual zooming adjustments.
Solution Approach 2:
The system changes key display parameters (focus area coordinates and enlargement factor) based on the detected screen size of the receiving device. By automatically adjusting these parameters, the system ensures that content remains readable across different screen sizes without requiring manual intervention from the presenter or participants.
2Ease of operation
If manual zoom is enabled for participants, then they can enlarge content, but they must constantly adjust and cannot efficiently select appropriate content
Solution Approach 1:
The system performs self-service by automatically detecting the receiver's screen size and computing the optimal focus area and enlargement factor without requiring manual input from the presenter. The system serves itself by adapting the content display based on detected device characteristics, thereby eliminating the time-consuming manual adjustment process while maintaining ease of operation.
3Measurement precision
If the same amount of text is displayed on smaller screens, then the display resolution is maintained, but the text becomes unreadable or illegible
Solution Approach 1:
The system applies local quality by focusing on and enlarging only the relevant portion of the shared content rather than attempting to display the entire screen. By concentrating the display resources on a focused area with appropriate enlargement, the system ensures that text and important elements remain legible on smaller screens while accepting that not the entire original screen area can be displayed.

AI summary
Methods and systems for allowing for techniques of automatically targeting focus and enlarging images upon detection that a receiver of shared video content is using a smaller screen. The presenter may indicate a focus point on the displayed video being shared to indicate where the targeted focusing and enlarging should be centered. A focus area and an enlargement factor may be calculated based on a difference in screen size between a presenter device and a destination device. The focus area and enlargement factor may be calculated such that elements of the shared video content are substantially the same size to a viewer of the destination device as they appear to the presenter on their presenter device. Different destination devices may have different focus areas and enlargement factors.
