Virtual Reality (VR) is the use of technology to create a simulated environment. It is a computer-generated 3D world in which a person can move around and interact. It is often described as “immersive” because it allows the user to feel as if they are part of the environment. The user wears a headset that covers their eyes and ears, and is outfitted with sensors that track their movements. This allows them to explore the virtual world and interact with it. An example of a virtual reality experience is a video game. In a game, the user is placed in a 3D world and the headset tracks their movements and responds accordingly. For example, if the user looks around, the game will follow where they are looking. Similarly, if the user moves their arms or legs, the game will respond accordingly. VR is also used in other applications such as education, training, and therapy. It can be used to simulate a classroom environment or a dangerous situation to teach students how to respond in such a situation. It can also be used to train medical personnel or to help treat PTSD and other psychological disorders by allowing the patient to interact with a virtual environment. According to the International Data Corporation (IDC), worldwide spending on virtual and augmented reality is expected to reach $20.4 billion in 2020. This is a strong sign that VR is quickly gaining traction. An analogy to explain virtual reality would be to imagine yourself inside a video game. Instead of controlling a character on a screen, the game is now inside your head and you are the character. You can look around, explore the world, and interact with objects. Fun Fact: The first virtual reality headset was developed in the 1960s by scientist Ivan Sutherland.
