In this video, the main idea is to show everyone how the brain transforms what we see by the objects surroundings. This is called an optical illusion. This talk was very useful because it taught me about things my eyes are tricked by everyday. I find it very interesting that our eyes and brain can process certain things one way or another and sometimes it can be deceiving.
The first example he showed everyone was the different colored dots on the two white and black boards. He let people try to guess which colors on the two boards were the same, and everyone was shocked by the results. The gray dots ended up being the same color when put side by side, but each gray dot that was on the white board and the black board, they appeared to be two different shades of gray. The reasoning behind this, is that the two black and white boards determine the ways your eyes see it. The white board made the gray dot look like a darker shade of gray, and the black board made the other dot look like a lighter shade of gray. When put together on the same board, they appear as the same color of gray.
The second example, he showed a picture of desert that was put in a mirror effect and split down the middle by a black line so each side of the picture was symmetrical. Above the picture was a a red box and on the other side was a green box. We were told to stare at the black dot in the center of the desert for 30 seconds. The purpose of doing this, is that when you stare at nothing but the black dot, after a while the two sides of the image slowly change colors. One side gets lighter and one side gets darker. The reason behind this is that two colors above the image are taken in by your eye lenses and create an illusion. Over all, this video taught me that everything I see is not true. When I look at something puzzling, I'm gonna think twice before i come to a conclusion.
