Week 2: Data Pipeline
Day 11: Body, Hands, and Face
Goal
Learn why whole-body tracking matters for ASL.
Learn
- Hands are critical, but ASL is not hand-only. Face, head, shoulders, torso, and signing space can carry grammar and meaning.
- A system that ignores facial grammar may miss questions, conditionals, negation, intensity, affect, or role shift.
- A system that ignores body movement may miss spatial agreement, stance changes, and where signs are placed in signing space.
Example
- For a question, the hands may carry the signs while the eyebrows and head position help show the sentence type.
- For role shift, the body may turn or lean to show a different person or viewpoint.
Practice
- Choose one ASL sentence or phrase.
- Make three columns: hands, face, and body/space.
- Write what each channel contributes.
Checkpoint
Before moving on
You can explain why ASL needs more than hand tracking.

Treat facial expression as language information, not decoration.
