Key standards

Visual physical commonsense (V-PC)

  • A person performs a hand clap inside a tile-floor hallway.
  • The same person walks outside and performs a hand clap in the open air.

Audio physical commonsense (A-PC)

  • The indoor clap carries a ringing reverberation tail from tiled-hallway reflections.
  • The outdoor clap is flat and dry with rapid decay.

Cross-modal physical commonsense (AV-PC)

  • Each clap sound aligns in time with its corresponding visible hand-clap action.
  • The reverberation character of each clap matches the visible space in which it occurs.
