Book Definition: Information about depth that relies on the input of just one eye-includes Relative Size, Relative Motion, Light and Shadow, Interposition, and Atmospheric Perspective. (pg 146)

Simply Put...

  • Cues are used for the depth perception that involves the use of only one eye.
  • When using monocular cues you can determine size, shape, motion and what the object is. Also use interposition to locate objects distant from yourself.

  • This image is an example that shows how monocular cues effect perception. The person who designed this picture specifically made it so that the 2D image did not have any monocular cues including color, relative size (so when the foot seems like it is behind it is not smaller than it is when it is infront), etc. If you look at this image long enough you will not be sure if it is moving left or right.
  • Relative Size:If two objects are roughly the same size, the object that looks the largest will be judged as being the closest to the observer.
  • Aerial Perspective:Objects that are farther away are blurred or slightly hazy due to atmosphere.
  • Overlap (or Interposition):When one object overlaps another, the object is perceived as being farther away.
