Visual perception
Visual perception is the ability to interpret the surrounding environment using light in the visible spectrum reflected by the objects in the environment. When an object is moving we tend to see if it moving from left to right or right to left. A good example of visual perception would be bistable image. Bistable image is when an image can be interpreted in one or two different possible ways. Another great example that tends to trick our vision is the hollow face illusion. The hollow face illusion is an optical illusion in which the perception of a concave mask of a face as a normal convex face, which appears to follow you as you move past it. Watch the video below to see how it works.

When I saw this I immediately thought about the "what color is the dress" phenomenon that happened a couple years ago. This is a great example of bistable image because some people saw it as blue and black, while others saw it as white and yellow/gold. It is so interesting that we see things differently than others even if it's as simple as a dress. Very cool!
