Life Projector 2.0

We redesigned our Life Projector as a full‑size zoetrope for the DIGF Experiences & Interfaces course (Assignment: IMMERSION).

Instead of sliding shadow frames, a spinning drum—rebuilt from old 3D‑printer Z‑axis parts—carries four silhouettes of human life:

1. Baby
2. Adult
3. Old Age
4. Death

A fixed bulb and Fresnel lens cast each frame onto a screen. A motorized Z‑axis platform lifts the drum to select which stage is in view.

How It Works

1. Story‑Driven Interaction

   • The user reads aloud an incomplete script with blanks to fill in four scripted passages—each stanza tied to a life stage.
   • A speech‑recognition program listens for keywords (baby, young, elder, demise) and identifies the current stage.

2. Voice → Motion

   • Python (voice_servo_control.py) sends a MOVE:current:target command over serial.
   • The Arduino (Test2_CntServo_LmtSwitch.ino) moves the reclaimed Z‑axis stepper to the new “stop” (stage).

3. Kinetic Projection

   • As the drum spins under the lamp, lifting it brings the next silhouette into focus.
   • Simultaneously, stage‑specific audio loops via Pygame enrich the experience.
