Monocular Cue: Interposition

Interposition is another type of monocular cue. This is described as if one object partially blocks the view of another, that object is perceived as closer.

We face this monocular cue every day of our lives when we are either inside of a building or outside.
For example, in the picture below of a man standing before several buildings downtown, we experience interposition right away. Instead of seeing a giant man towering over the hundred-feet high buildings, this monocular cue tells us that because this man partially blocks the objects ahead of him, the man is in fact closer to us.
