binocular depth cues.

Question 1

what are depth cues?

Answer 1

Depth cues are visual signals that help us perceive how far away or close things are—giving us a sense of depth and distance.

Question 2

what are binocular depth cues?

Answer 2

Binocular depth cues are visual cues that require both eyes to perceive depth and distance. They help us see the world in 3D by comparing the slightly different images from each eye.

Question 2

why does each eye have a different image projected on the retina?

Answer 2

because each eye is 6-7cm apart (2.5inches) each retina receives a slightly different angle of view from each eye.

Question 3

what are the two binocular depth cues?

Answer 3

retinal disparity and convergence

Question 4

what is retinal disparity?

Answer 4

Retinal disparity is a binocular depth cue that helps your brain perceive depth and distance by comparing the slightly different images seen by each eye.

Question 5

what does the brain do in retinal disparity?

Answer 5

the brain takes note of both differing images and creates a cohesive/combined image.

Question 6

what is convergence?

Answer 6

Convergence is a binocular depth cue that helps your brain judge how close an object is by measuring how much your eyes turn inward to focus on it.
- closer the object = higher tension in eye muscles (eye’s turn in)
- further away the object = less tension.
