Sentiment-Aware Sign Language Avatar for Accessible Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Deaf individuals face challenges in fully enjoying audio-visual content due to difficulties in processing the audio component, which can lead to missed visual cues and reduced comprehension.
Innovation Solution
The system generates a virtual avatar that speaks sign language, synchronizing with the audio-visual content to provide real-time sign language interpretation, emotional state representation, and customizable appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If text subtitles are provided for audio-visual content, then hearing-impaired individuals can access audio information, but they struggle to process rapidly moving text and may miss visual cues such as facial expressions
Solution Approach 1:
The patent creates a virtual avatar that copies and translates spoken dialogue into sign language performance. The avatar replicates the speaker's words through standardized sign language gestures while maintaining visual accessibility, allowing hearing-impaired users to comprehend audio information through a visual medium they can process efficiently without missing other visual cues in the content
Solution Approach 2:
The system transforms audio information into a different modal parameter - from auditory speech to visual sign language gestures. By changing the parameter of information delivery from sound waves to standardized manual gestures, the system makes audio content accessible to hearing-impaired individuals at natural processing speeds without requiring rapid text reading
2Productivity
If a virtual avatar is generated to provide sign language interpretation, then comprehension efficiency improves, but system complexity increases
Solution Approach 1:
The virtual avatar serves multiple functions simultaneously: it translates spoken dialogue into sign language, conveys emotional tone through facial expressions, and provides visual synchronization with the audio-visual content. This multi-functionality consolidates what would otherwise require separate subtitle systems, emotion detection mechanisms, and synchronization tools into a single integrated solution
Solution Approach 2:
The virtual avatar acts as an intermediary between the audio-visual content and hearing-impaired users. Rather than directly presenting raw audio or simple subtitles, the avatar mediates the information by translating and adapting it into appropriate sign language form, simplifying the interaction complexity for end users while handling the transformation complexity in the background
3Loss of information
If the avatar exhibits emotional states through facial expressions, then emotional context is preserved, but the difficulty of detecting and measuring emotional states increases
Solution Approach 1:
The system implements feedback loops where the avatar's emotional expressions are continuously adjusted based on analysis of the original audio-visual content's emotional cues. By detecting emotional states in the source material and feeding this information back to modulate the avatar's facial expressions and gestures in real-time, the system preserves emotional context while using automated detection to manage the complexity of emotional state measurement

AI summary
Systems and methods for doing presenting an avatar that speaks sign language based on sentiment of a speaker is disclosed herein. A translation application running on a device receives a content item comprising a video and an audio, wherein the audio comprises a first plurality of spoken words in a first language. The video comprises a character speaking the first plurality of spoken words in the first language. The translation application translates the first plurality of spoken words of the first language into a first sign of a first sign language. The translation application determines an emotional state expressed by the character based on sentiment analysis. The translation application generates an avatar that speaks the first sign of the first sign language where the avatar exhibits the determined emotional state. The content item and the avatar are presented for display on the device.
