A VR headset is a device worn over the eyes that immerses users in a virtual environment. It uses screens and sensors to create a 3D experience, making you feel like you're inside a video game or a different world. With a VR headset, you can look around and interact with the environment, enhancing your gaming or educational experience. These headsets often come with controllers that allow you to move and manipulate objects in the virtual space. Popular brands like Oculus and HTC Vive have made VR technology accessible, providing exciting opportunities for entertainment, training, and even therapy.
