Depth Cues

What depth cue is being illustrated here?

• retinal disparity

• relative size

• occlusion

• linear perspective

What is the difference between linear perspective and convergence?

• Convergence is a binocular depth cue where our eyes converge whereas linear perspective is a monocular depth cue where the image we see appears to converge

• Convergence is a monocular depth cue where our eyes converge whereas linear perspective is a binocular depth cue where the image we see appears to converge

• Convergence is a binocular depth cue where the image we see appears to converge whereas linear perspective is a monocular depth cue where our eyes converge

• Convergence is a monocular depth cue where the image we see appears to converge whereas linear perspective is a binocular depth cue where our eyes converge

Match the monocular depth cue to the image

• Height in Plane

• 
• Linear Perspective

• 
• Relative Size

• 
• Occlusion

• 

Following eye surgery, Ava wears an eye patch to cover her left eye for one week. She notices that wearing the eye patch makes her clumsy and she often bumps into furniture as she moves around her house.

a) Outline one binocular depth cue that affects how people judge distance.
b) Refer to Ava’s experience in your answer.

Which of the following is a binocular depth cue?

• Relative size

• Height in plan

• Linear perspective

• Retinal disparity

This is an illustration of which binocular depth cue?

• Occlusion

• Height in plane

• Convergence

• Retinal disparity

When our eyes look slightly inward to view something closer to us...

• our vision becomes blurry so our brains have to guess the depth

• we detect the muscle movement and our brains perceive a change in the depth

• the muscles around our eyes relax and we find it easier to perceive the depth

• our vision becomes sharper so our brains have a better perception of the depth

Why might the tree near the top right look bigger than the tree in the bottom left?

• height in plane tell us it's further away but size constancy makes us perceive it as bigger as the relative size has not changed

• the distance between the trees creates retinal disparity so we wrongly perceive the tree to be bigger

• linear perspective draws our eyes towards the tree at the back and our attention makes us focus more on that tree so we perceive it as bigger

• the tree on the right is actually bigger in our visual array so viewing it in 2D causes us to perceive it as bigger because it is drawn as bigger
