Virtual reality (VR) is a simulated experience that can be similar to or completely different from the real world. Applications of virtual reality can include

How does VR technology fool our brains?

VR here stands for Virtual Reality

Our eyes and ears work the same whether we are in a real world or a virtual one. When we simulate the way we experience the real world—for instance, by simulating three- dimensional scenes using stereoscopic vision—VR can make us feel like as if we are in a different world altogether, but a very realistic-feeling one.


To understand how effective VR works, we first need to understand a little about how the brain makes sense of the world around us.

Stop and think about the senses that allow us to experience the world: vision, hearing, and touch, to name a few. To make sense of the world, the brain needs to first bring in information from sensory organs, such as the eyes, ears, and skin. But bringing in the information only describes sensation

—the act of transmitting information from the sense organs to the brain.

What happens next is that the brain interprets this information, allowing us to understand what is happening in the environment. The brain’s interpretation of the senses which create our understanding is called perception-The process of our brain interpreting our sense to experience.

For instance, we can see a dog running across the room, hear her bark, and feel her fur brush against our skin—these are sensations that we come to understand and perceive as experiences.

The sensations all come together through perception to give us the experience of the dog. It is this interplay of sensation (using vision, hearing, etc.) and perception (our brain’s interpretation of this information) that creates our experience of reality.
