I remember my family often drove to travel to small towns where the atmospheres were completely different from city area when I was young. My father was always driving and that enabled me to look the views over the car window. I remember that I was very excited whenever I saw the cows closed to the road because they were moving very fast. They were moving even faster than the airplanes from my viewpoint. So I believed that cows are much faster than airplane and, thus, I thought it was way better idea to riding a cow to travel around. My parents told me that it just “seemed” like cows are moving faster when I was in a riding car. It took little time to understand this logic and change my thought that cows are inadequate transportation that I could use for travel.
To understand me perfectly, my father drove little faster and suddenly slowed down. As he repeated, he told me to how cows are moving slower as he drove slower. But I still could not completely understand because the airplane in the sky was still moving slower than cows. For this question, my father told me that it was matter of distance. He told me that airplane would be so fast if I see that by the side. I did not fully understand with his explanation until I actually see the airplane really closed at the airport.
This childhood experience was the first thing came to my mind when we were covering the motion parallax in the lecture. The motion parallax was a comprehensive term for my father’s explanation. Motion parallax, according to lecture, is a depth cues that objects closed to us move faster across the visual field than objects farther way. This was why airplane seemed move way slower than cows from my viewpoint when I was in a car driving.
