what is a vr headset

A virtual reality headset, or VR headset, is a head-mounted device that provides virtual reality for the wearer. VR headsets are widely used with VR video games but they are also used in other applications, including simulators and trainers. VR headsets typically include a stereoscopic display (providing separate images for each eye), stereo sound, and sensors like accelerometers and gyroscopes for tracking the pose of the users head to match the orientation of the virtual camera with the users eye positions in the real world. Some VR headsets also have eye-tracking sensors and gaming controllers. When a user puts on a VR headset, they can no longer see the world around them, but instead only see VR content projected on the display screen such as 360-degree videos and VR games, workspaces, or meeting rooms for other activities. Unlike augmented reality (AR) headsets or mixed reality (MR) headsets, VR headsets do not allow users to see any element of the external physical world. Along with the headset itself, the user will rely on a set of VR controllers to navigate the experience. VR apps for both mobile and tethered apps incorporate technology such as gaze tracking, IR sensors, gyroscopes, and accelerometers to move the user’s point of view in a natural manner. VR headsets are divided into low-end, mid-range, and high-end virtual reality headsets.
