More expressive signing avatars
Connecting facial motion capture, animation, and the non-manual elements of sign language.
Facial motion carries meaning
In sign languages, communication extends beyond hand movements. Facial expressions and other non-manual elements can carry linguistic information. A signing avatar needs to account for these elements as part of the communication itself.
From motion to animation
My doctoral work at UNICAMP investigated modeling and synthesizing facial aspects of Brazilian Sign Language for signing avatars. Related work explored facial motion capture, marker placement, and mapping captured movements to a realistic avatar.
A connected research thread
The work brings together computer vision, computer graphics, language, and accessibility. It continues to inform the human-centered questions I bring to applied AI.

- Non-manual expressions in intensification in Libras
A useful project starts with a clear question.
