Key standards

Visual physical commonsense (V-PC)

  • The person strikes the door twice with a hand, first as a gentle knuckle tap and then as a forceful fist pound, with each hand impact visibly contacting the door itself.

Audio physical commonsense (A-PC)

  • The forceful fist pound is noticeably louder than the gentle knuckle tap.
  • Each impact sound is a real hand-on-door impact.

Cross-modal physical commonsense (AV-PC)

  • Each impact sound aligns in time with the visible contact of the hand on the door.
  • The louder impact corresponds to the forceful fist pound.
  • The quieter impact corresponds to the gentle knuckle tap.
