First-person egocentric view in a narrow indoor hallway. The listener walks toward a visible loudspeaker mounted on the right wall while continuous music plays; as the listener approaches and passes it, the sound is perceived from behind first and only shifts to the front after the speaker has already been passed.

Key standards

Visual physical commonsense (V-PC)

  • A first-person camera walks continuously down a narrow indoor hallway toward a visible loudspeaker mounted on the right wall, then continues past it.

Audio physical commonsense (A-PC)

  • Continuous music plays uninterrupted throughout the clip with consistent musical content.

Cross-modal physical commonsense (AV-PC)

  • While the loudspeaker is still visibly ahead of the camera, the music is localized behind the listener in the audio field.
  • After the camera has visibly passed the loudspeaker, the music shifts to be localized in front of the listener.
