Week 2: Data Pipeline

Day 11: Body, Hands, and Face

Day 11 of 2818 minGoal - Learn - Example - Practice - Checkpoint

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

  1. Choose one ASL sentence or phrase.
  2. Make three columns: hands, face, and body/space.
  3. 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.
