Module 4.1: What is Virtual Reality

Virtual Reality (VR): A computer-generated simulation of a three-dimensional environment that users can interact with using special equipment, such as VR headsets. In education, VR can provide immersive experiences, allowing students to explore virtual environments and scenarios.

VR Head-Mounted Displays (HMDs) are devices worn on your head that allow you to experience Virtual Reality (VR). They are like goggles or helmets with built-in screens that show a 3D, computer-generated environment. When you wear an HMD, it covers your eyes, blocking out the real world and replacing it with a virtual one.

These displays track your head movements, so when you look around, the virtual world moves with you, making it feel like you’re really inside the experience. Many HMDs also come with headphones for 3D sound and controllers to let you interact with the virtual environment. Examples include devices like the Oculus Quest, PlayStation VR, or HTC Vive.

HMDs are key to making VR immersive and engaging, whether for gaming, education, or training.
