Question
What are monocular cues?
Solution
Monocular cues or depth perceptions are effective only when the objects are viewed with only one eye. These cues are used by artists to induce depth in painting. Thus they are also called as pictorial cues. Some of the molecular cues are:
(i) Relative Size: The size of the retinal image allow us to judge distance based on our past and present experiences with similar objects. As the object gets away the retinal image become smaller and smaller.
(ii) Interposition or Overlapping: These cues occur when some portion of the object is covered by another object.
(iii) Linear Perspective: This reflects the phenomena by which distant object appear to be closer than nearer object.
