Verified step by step guidance

1. Understand the concept of depth perception, which is the ability to perceive the world in three dimensions and judge the distance of objects.
2. Recognize that depth cues are signals that help us perceive depth and distance. These cues can be categorized into two types: monocular and binocular.
3. Monocular cues are depth cues that can be perceived with one eye alone. Examples include relative size, interposition, and linear perspective.
4. Binocular cues require the use of both eyes and include retinal disparity and convergence, which help in perceiving depth more accurately.
5. Identify that pictorial depth cues are a type of monocular cue, meaning they can be perceived with just one eye, and are used in art to create the illusion of depth on a flat surface.
