Virtual reality headsets are devices worn over the eyes that create immersive digital environments. They use screens and sensors to track head movements, allowing users to look around and interact with 3D worlds. This technology is commonly used in gaming, training simulations, and virtual tours. These headsets often come with built-in audio and may include handheld controllers for a more interactive experience. Popular models include the Oculus Quest, HTC Vive, and PlayStation VR. As technology advances, virtual reality is becoming more accessible and is being explored for applications in education, therapy, and social interaction.
