Binocular Depth Cues
Captions available
The idea
Binocular depth cues require both eyes and arise from the slightly different images each eye receives.
In practice
Holding a finger close and alternating eyes shifts its apparent position sharply against the background.
Where people slip
Binocular cues dominate only at close range. Beyond a few meters, the two images converge.
