A smartphone lies on a bed playing music at a steady volume in a quiet bedroom; initially, the phone is fully uncovered and the music sounds normal; a thick pillow is then placed directly on top of the phone, completely covering the speaker; the sound becomes louder, clearer, and brighter after being covered, with increased high-frequency detail.

Key standards

Visual physical commonsense (V-PC)

  • A smartphone lies fully uncovered on a bed at the start of the clip, visibly playing music with no pillow on top.
  • A thick pillow is then placed directly on top of the smartphone, completely covering the phone speaker for the rest of the clip.

Audio physical commonsense (A-PC)

  • The music in the uncovered phase plays at a steady volume with the typical small-speaker character of phone audio.
  • The music in the covered phase becomes noticeably louder, clearer, and brighter than in the uncovered phase, with increased high-frequency detail.

Cross-modal physical commonsense (AV-PC)

  • The shift to louder clearer brighter music aligns in time with the moment the pillow visibly covers the smartphone speaker.
