Key standards

Visual physical commonsense (V-PC)

  • The foam block compresses under the stick and visibly springs back to its original shape when released, remaining intact throughout the clip.

Audio physical commonsense (A-PC)

  • Each compression has a soft, muted timbre with a subtle air-release character.

Cross-modal physical commonsense (AV-PC)

  • Each compression sound aligns in time with a visible push of the stick into the foam.
