Virtual reality (VR) is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business (such as virtual meetings).

VR headsets are the most common way to experience VR. They typically have a head-mounted display (HMD) with a screen in front of each eye, and sensors that track the user’s head movements. This allows the user to look around the virtual world and interact with it in a natural way.

Other VR devices include hand-held controllers, treadmills, and even entire rooms that are outfitted with special displays and sensors. These devices can be used to provide a more immersive VR experience, but they are also more expensive and complex.

VR is a rapidly growing technology with a wide range of potential applications. It is already being used in a variety of industries, and its use is expected to grow in the years to come.
