Key standards
Visual physical commonsense (V-PC)
- A young man stands in the middle of a flat open grass field and visibly claps his hands.
- The surrounding environment is open with no walls, ceilings, or large reflective surfaces visible anywhere in the frame at any time.
Audio physical commonsense (A-PC)
- The clap has the sharp percussive slap of two human palms meeting.
- Following each clap, the audio carries a long sustained reverberation tail with the dense diffuse decay character of a large indoor concert hall.
Cross-modal physical commonsense (AV-PC)
- Each clap onset aligns in time with the visible palm contact of the young man.
