Virtual reality (VR) experiences are powered by technologies such as head-mounted displays (HMDs), motion tracking, and 3D graphics. These technologies work together to immerse users in a computer-generated environment that simulates real-world experiences. VR systems use sensory feedback, including sight, sound, and sometimes touch, to create engaging and interactive experiences. Popular applications of VR include gaming, training simulations, and virtual tourism, transforming how we interact with digital content and environments.
