Key standards

Visual physical commonsense (V-PC)

  • The wrench visibly falls from a raised position and lands on the pillow, with the pillow visibly compressing on impact.

Audio physical commonsense (A-PC)

  • The landing is a soft, muffled, dull thud at low loudness, with the timbre of a metal object on a thick pillow.

Cross-modal physical commonsense (AV-PC)

  • The thud onset aligns in time with the visible moment the wrench contacts the pillow, with audio remaining continuous from the start of the visible fall through the landing.
