Monocular and Binocular Depth Cues

In this video, we continue our discussion of the human perceptual system by discussing how we perceive depth. Using a variety of examples and demonstrations, we focus specifically on the two types of cues critical for depth perception: monocular depth cues and binocular depth cues.
Monocular Depth Cues: Depth cues that only require one eye to see.
Binocular Depth Cues: Depth cues that require both eyes to see.
Relative Size: The first monocular depth cue, which states that, all else being equal, more distant objects tend to look smaller.
Texture Gradient: The second monocular depth cue, which states that object textures become less apparent farther away.
Interposition: The third monocular depth cue, which states that if Object A blocks our view of Object B, Object A must be closer to us than Object B; also known as “occlusion.”
Linear Perspective: The fourth monocular depth cue, which states that parallel lines converge as distance increases, eventually meeting at a vanishing point.
Height in Plane: The fifth monocular depth cue, which states that distant objects tend to appear higher in our visual planes than closer objects.
Light and Shadow: The sixth and final monocular depth cue, in which objects cast shadows that tell us their 3-dimensional shapes.
Binocular Disparity: The first binocular depth cue; because our two eyes are offset, they produce two different images; our brains use the disparity between these images to calculate depth, with larger disparities meaning closer objects.
Binocular Convergence: The second and final binocular depth cue; looking at closer objects causes our eyes to converge; our brains use this information to calculate depth, with more convergence meaning closer objects.

This is an amazing video! Cleared most of my doubts. Im taking ap psychology exam btw

Am an optometrist from India, Kerala....your explanation is really hepful...Thank you so much sir

[@naziraa.8906]

Great explanations with examples. I've been reading an article about depth cues and couldn't catch a thing, now I understand a lot after watching your video.

Yes it is....

thank you for helping me understand these two concepts so well!! very good examples and simple demonstration for easy understanding! our brain is brilliant!

Excellent video with great explanation. I have an exam today and it is very helpful. Thank youu

[@yzkkoch479]

At first, when I was reading the keywords for visual cues and constancies on the AQA psychology textbook I was so confused. But now that I watched this I definitely understand way better and I re read the keywords and they make much more sense !! Thank you so much! You explain so simply which makes it easier to understand👏

I’ve never really had binocular depth perception (3D movies are surreal to me and nauseating since the glasses force my brain to process binocular vision) but know my brain still understands depth. This was interesting to learn the actual mechanics for my level of depth perception

[@ego-lay_atman-bay]

I've actually never had binocular depth perception, all because I'm blind in my right eye. I kept hearing that you need two eyes to perceive depth, so I thought for a while that I didn't have any depth perception. Now I know that I do indeed have depth perception, I just only have monocular cues. The biggest downside for only having one eye, is that I can't experience 3d movies the same way everyone else can. I can only see one image, so it looks like I'm just watching a regular movie. If some genius could invent 3d glasses that are tailored specifically towards people with only monocular vision, basically recreating the 3d image that normal people see with 3d glasses. I believe that this is only possible using technology, so I may actually be able to create those glasses in the future (I'm a programmer).

[@beepbop6697]

3D movies that use those glasses are "fake 3D". The screen is projecting two separate 2D images (one for each eye) that tricks the brain into seeing a 3D scene using parallax. Having two eyes, I can tell you it isn't really that realistic, and you aren't missing much -- I prefer to watch the 2D version of the movie without the forced distracting "trying too hard" parallax effects. What we need are truly 3D holographic movies, that require you to focus differently for the near parts vs the far parts -- and that sort of holographic movie would work for your monocular vision as well as us (with two eyes) without the need for the special glasses.

You forgot the most important one out there. As we are not living in a picture, but in a world where our vision is mainly moving, closer objects move faster than objects far away.
