Även Efter Man Läst Förklaringen Och Verkligen Försöker Bortse Skuggans Illusion, Så Stuttsar Denna

Även efter man läst förklaringen och verkligen försöker bortse skuggans illusion, så stuttsar denna boll...

Skulle det fungera om man tog bort perspektiv rutorna? Så du inte har djupet att förhålla sig till?... Hmm

Shadow Illusion

Shadow illusion

The human brain uses shadows to interpret how objects move. By faking the shadow, one can fake the perceived motion of an object. The red circle moves along a line.

Does this post explain this aswell? https://www.youtube.com/watch?v=uENITui5_jU

The Strobe Light Conundrum

The Strobe Light Conundrum

The post - Illusion of Perception obviously confused a lot of people since I have been getting a lot of requests to explain it again.

Let me try it again with another animation.

The setup

The illusion of falling droplets is created by a pump which is pushing out the water droplets at a fixed rate. ( call it X ) - Does NOT change.

Changing the frequency of the strobe light ( call it Y ) is the integral part of the illusion.

image

The flow is similar to that of your shower head. The water droplets are continuously falling down. With the strobe light, we are just illuminating the droplets at different instances of time.

When  X = Y  —>  The droplets appear stationary.

Imagine yourself to be sitting on top of the hose and watching every drop fall through. Whenever the droplet of water is about to leave the hose, the light flashes. This renders the droplet as stationary.

Let us call the distance between the droplets as L.

image

When Y > X  — > The droplets appear to move up.

Now, the strobe light flashes a little too quickly than the rate of the drop falling. This gives us the illusion of droplets moving up since you are flashing the light before the droplet has traversed the distance L.

image
image

When Y < X  — > The droplets appear to move down.

Now, the strobe light flashes a little slower than the rate of the drop falling. This gives us the illusion of droplets moving down since you are flashing the light after the droplet has traversed the distance L.

Thank you so much for expressing your concerns and I apologize if it had confused you. I hope this post made it up

Have a good day :)

EDIT - Here is the actual gif from the illusion of perception post.
