Key standards

Visual physical commonsense (V-PC)

  • A person sits inside a cafe interior while the cafe front door visibly opens and then closes.
  • The door motion is continuous and the cafe geometry remains stable throughout the clip.

Audio physical commonsense (A-PC)

  • Street noise is quiet inside the cafe while the door is closed.
  • Street noise becomes loud and broadband while the door is open.
  • Street noise drops back to a quiet residual after the door closes again.

Cross-modal physical commonsense (AV-PC)

  • The surges and drops in street noise align in time with the visible opening and closing of the cafe door.
