Virtual reality systems are immersive technologies that create a simulated environment, allowing users to interact with 3D spaces and objects. These systems typically use a combination of hardware, such as headsets and motion controllers, to provide a realistic experience. Users can explore virtual worlds, play games, or engage in training simulations, making VR a versatile tool for entertainment and education. The core components of a virtual reality system include a VR headset, which displays the virtual environment, and motion sensors that track the user's movements. Some systems also incorporate haptic feedback devices to enhance the sense of touch, further enriching the immersive experience.
