Dynamic Video Presentation Scaling for Readability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Videoconferencing systems face challenges in optimizing video presentations due to varying complexity and participant distance, leading to difficulties in ensuring that presentation content is easily readable and visible for all participants.
Innovation Solution
A method and system that automatically scale video presentation content based on the complexity of the material and the distance of participants from the display area, using face detection, voice positioning data, and multiple camera angles to determine participant location and adjust the display accordingly, allowing the presentation to be displayed on an appropriately sized screen or across multiple screens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed display size is used for video presentations, then the system is simple to implement, but presentation content becomes unreadable or invisible when participants are far from the display
Solution Approach 1:
The display size is made dynamic rather than fixed. The system automatically adjusts the display scale based on real-time detection of participant distance from the display area, ensuring optimal readability for each participant's position
Solution Approach 2:
The system uses feedback from distance detection (via cameras or sensors) to automatically adjust display scaling. The detected participant distance serves as feedback to control the display size, creating a closed-loop system that adapts to changing conditions
2Ease of operation
If the display size is increased to accommodate distant participants, then visibility improves, but the display becomes too large or inappropriate when participants are close
Solution Approach 1:
The display size dynamically adapts to participant distance, automatically adjusting between large and small display states based on real-time distance detection, ensuring optimal visibility regardless of whether participants are close or far from the display
Solution Approach 2:
The system changes the display parameter (size) based on detected participant distance. By adjusting the display size parameter in response to distance measurements, the system optimizes visibility for different viewing distances
3Ease of operation
If presentation content is scaled up for distant participants, then readability improves, but the content becomes blurry or distorted when viewed from close distance
Solution Approach 1:
The display scaling is dynamic and adaptive, adjusting the display size based on real-time distance detection to maintain optimal content quality and readability for each participant's position without blurring or distortion
Solution Approach 2:
The system uses feedback from distance detection to control display scaling, ensuring that content is displayed at the appropriate size and quality level for each participant's distance, preventing both blurriness and distortion

AI summary
A method is provided in one example embodiment and includes receiving a first presentation material for a videoconference, wherein the first presentation material is to be displayed in a display area associated with the videoconference; determining a first complexity of the first presentation material; and displaying the first presentation material on a first display based on the determined first complexity. In more particular embodiments, the method can include determining a location of a participant that will view the first presentation material; and displaying the presentation material on a second display based on the location of the participant. The location of the participant can be determined using audio data or video data.
