The technology used to create virtual reality environments typically involves head-mounted displays (HMDs) and motion tracking systems. HMDs provide immersive visual experiences by displaying 3D graphics, while motion tracking systems enable user interactions and movements to be reflected within the virtual world. Devices like motion controllers enhance interactivity, allowing users to manipulate virtual objects. Combining these technologies results in a compelling, immersive experience that mimics real-life sensations and interactions, applicable in gaming, training, and simulations.
