Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote learning environments in videotelephony sessions face challenges such as limited attention focus, difficulty in recognizing viewer engagement, and privacy concerns due to full body representations, leading to ineffective learning experiences.
Innovation Solution
A system that evaluates interactions during videotelephony sessions, transforms actual representations into avatar representations, and selectively modifies them based on context and sentiment, while mitigating bandwidth usage and protecting privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If full body representations are used in videotelephony sessions, then privacy protection is improved, but viewer engagement recognition and learning effectiveness deteriorate
Solution Approach 1:
The patent segments the representation into two distinct forms: avatar representation for privacy protection and selective body part representation (hands, face) for engagement recognition. This segmentation allows the system to simultaneously achieve privacy protection through avatars while maintaining learning effectiveness by selectively displaying body parts that convey engagement signals.
Solution Approach 2:
The patent applies local quality by selectively modifying different parts of the representation - using full avatar for identity protection while selectively revealing specific body parts (hands for gestures, face for expressions) that are critical for conveying engagement and emotional state, thus maintaining learning effectiveness without compromising overall privacy.
2Object-affected harmful factors
If avatar representations are used to protect privacy, then privacy protection is improved, but viewer engagement and emotional state recognition deteriorate
Solution Approach 1:
The patent introduces selective body part representations (hands, face) as intermediaries that convey engagement and emotional information without revealing full identity. These body parts serve as mediators that transmit engagement signals while the avatar maintains privacy protection, thus resolving the contradiction between privacy and engagement recognition.
Solution Approach 2:
The patent applies local quality by selectively revealing specific body parts (hands for gestures, face for expressions) that are critical for conveying engagement and emotional state, while maintaining avatar representation for privacy protection. This localized revelation enables engagement recognition without compromising overall privacy.
3Productivity
If selective body part representations are used, then focus and engagement recognition are improved, but bandwidth usage increases
Solution Approach 1:
The patent segments the video representation into avatar components and selective body part components, allowing the system to transmit only the necessary visual information for engagement recognition. This segmentation reduces overall bandwidth usage compared to transmitting full body representations while maintaining focus and engagement recognition through selective body part display.
Solution Approach 2:
The patent extracts and transmits only the essential body parts (hands, face) that convey engagement information, removing unnecessary visual data. This extraction approach reduces bandwidth consumption while maintaining the ability to recognize viewer engagement and emotional state.
4Device complexity
If remote learning is conducted through single window interaction, then device complexity is reduced, but viewer attention focus and learning effectiveness deteriorate
Solution Approach 1:
The patent applies dynamics by dynamically adjusting the representation type based on the learning context - using avatars for privacy protection during identity-sensitive moments and selectively revealing body parts during engagement-critical moments. This dynamic adaptation enhances learning effectiveness within the simple single-window interface without increasing device complexity.
Solution Approach 2:
The patent applies local quality by selectively enhancing specific areas (body parts) within the single window to convey engagement and emotional information, making the simple interface more effective for learning while maintaining device complexity at acceptable levels.

AI summary
Facilitating avatar modifications for learning and other videotelephony sessions in advanced networks is provided herein. Operations of a system include evaluating a recorded interaction associated with a first entity during consumption of a first portion of a video conference determined to include the first entity. The operations also can include transforming an actual representation of the first entity in the recorded interaction to an avatar representation, resulting in an edited interaction of the first entity. Further, the operations can include outputting the edited interaction of the first entity for consumption of a second portion of the video conference by rendering the edited interaction for a second entity.
