Key standards

Visual physical commonsense (V-PC)

  • A visible dog barks inside a closed garage with its mouth and jaw moving in sync with each bark.
  • The same dog barks in an open backyard with its mouth and jaw moving in sync with each bark.

Audio physical commonsense (A-PC)

  • The garage bark carries a ringing reverberation tail from concrete walls.
  • The backyard bark is flat and dry with rapid decay.

Cross-modal physical commonsense (AV-PC)

  • Each bark sound aligns in time with the dog's visible barking action.
  • The reverberation character of each bark matches the visible space in which it occurs.
