A virtual reality headset is a device worn over the eyes that immerses users in a computer-generated environment. It typically includes two small screens, one for each eye, which create a 3D effect. The headset often features sensors to track head movements, allowing users to look around and interact with the virtual world. Many virtual reality headsets also come with built-in audio and may include handheld controllers for a more interactive experience. They are used in various fields, including gaming, education, and training, providing users with a unique way to experience digital content.
