Key standards

Visual physical commonsense (V-PC)

  • A person punches a soft pillow first, then punches a separate hard wall.
  • The fist visibly contacts each surface during its corresponding punch.

Audio physical commonsense (A-PC)

  • The pillow punch sound is dull and muffled with no audible reverb tail.
  • The wall punch sound is louder and sharper than the pillow punch, with at most a slight short ring.
  • Each impact sound has the natural timbre of a fist striking its respective surface.

Cross-modal physical commonsense (AV-PC)

  • Each impact sound onset aligns in time with the visible fist contact on its surface.
