Spatial Order Essay Example: The Ability and Significance to Perceive Depth of a Scene

Human eyes have developed the ability to see and become aware of the distance of an object – this phenomenon is known as depth perception. It starts to develop in a child who’s not more than two months old. However, it takes two eyes to develop this phenomenon. When both of these eyes look at an object, they create two images simultaneously, which are a little different from one another.

Depth perception is also responsible to form an idea of length, width and height of an object. This premise functions on a subconscious level and so quickly that we are not aware of the fact that it is actually happening. However, people with one eye might find depth perception very problematic – the phenomenon works ideally in binocular disparity (two-eyed normal vision). Neurological studies, however, suggest that the human brain has the capacity to manipulate depth of a scene with monocular vision (one eyed vision) too.

Depth perception is created by a process known as stereopsis. This process enables the brain to overlap two images created by our eyes that are processed with information given by parallax – an effect that creates a distinction between close and background objects by slowing down background objects rather than the objects closer to our eyes. Having monocular vision still let us experience parallax, but it’s not as good as binocular vision.

Depth perception is very important to keep us safe. It is the only reason that lets us know the distance of an object or how far an object is from us. Without this phenomenon taking place in our lives, it becomes very hard to differentiate between far and close objects. For example, if a person doesn’t have proper depth perception and a car is coming in his/her direction at a velocity of 200 km/h, he/she wouldn’t know how to judge the speed of the oncoming car and how far or close it is from him/her.

Poor depth perception can lead to confusion during such dire situations which leads to high fatality risks. However, since our brain can manipulate depth perception, we can train ourselves to create depth of a scene through specific exercises.

Scientists actually believe that depth perception is nothing more than a pseudo-3D effect that enables us to determine length, width and height of an object; and let us know how far or close an object is to us. However, our eyes are not capable of perceiving actual three dimensions when viewing objects. If we had real 3D perception, we would have been able to see an entire 3D object at once. But having a depth perception, even if it’s a pseudo effect, is very important to performing day to day tasks without any hindrances or running into accidents.

This is the end of our second guide. Next up, we have a third guide which explains how to write an evaluation essay properly – it assists you in writing the perfect evaluation essay which will no doubt be the subject of admiration by your professors.
