Sign Language Animation for Video Audio Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing impaired individuals struggle to understand video and audio communications due to their inability to hear or process auditory signals effectively.
Innovation Solution
A system and method that converts video or audio into sign language animation, utilizing a process engine to extract audio from video, transcribe it into text, and then generate sign language animated frames based on the text, allowing hearing impaired users to understand conveyed messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If video or audio is converted into sign language animation, then hearing impaired users can understand conveyed messages, but device complexity increases
Solution Approach 1:
The system segments the communication accessibility solution into distinct functional modules: an audio extractor that separates audio from video, a text transcriber that converts audio to text, and a sign language animator that generates animated sign language representations. This modular segmentation allows each component to be optimized independently while collectively solving the accessibility problem without requiring complete system redesign
Solution Approach 2:
The patent introduces text as an intermediary representation between audio and sign language animation. The audio is first transcribed into text, which then serves as the input for generating sign language animation. This intermediary text layer simplifies the overall transformation process and enables flexible processing at each stage, reducing the complexity burden on any single component
2Reliability
If audio is extracted and transcribed to text, then sign language animation can be generated, but loss of time occurs in the conversion process
Solution Approach 1:
The system performs preliminary actions by extracting and transcribing audio to text in advance, before the actual communication needs to be conveyed to hearing impaired users. This allows the text representation to be pre-prepared and ready for rapid sign language animation generation, reducing the perceived conversion time during actual use
