Research papers on 2D and 3D avatars, along with AI technology journals, provide deeper insights into these types [2].
How Sign Language Avatars Work
The technology behind sign language avatars involves a combination of motion capture, AI, and rendering techniques.
Motion Capture
- Recording: Human signers perform gestures, which are recorded using motion capture technology.
- Mapping: The recorded movements are mapped onto a digital avatar.
- Animation: The avatar replicates the gestures with precision.
AI and Machine Learning
- Data Collection: Large datasets of sign language gestures are compiled.
- Training: AI models are trained to recognize and generate sign language.
- Generation: The AI produces real-time translations based on input.
Rendering
- Modeling: The avatar’s 3D structure is created.
- Texturing: Realistic textures are applied to the avatar.
- Animation and Rendering: The final animations are rendered for display.
Motion capture technology guides and AI research provide detailed explanations of these processes [3].
