### Notable For
- As a standalone virtual reality device that incorporates all necessary components into a self - contained unit.
- Utilizes stereoscopy for 3D visual experiences, enhancing immersion.
- Distinguished from mixed reality headsets by focusing solely on virtual environments.
- Includes brands like Oculus (founded 2012) and models such as Oculus Rift (2016) and Valve Index.
- Features common hardware components like display devices, lenses, and head straps.

### Body
#### Classification and Relationships
A virtual reality headset is classified as a **head - mounted display** and a **peripheral** hardware device. It belongs to the broader category of stereoscopes, which use stereoscopy to create 3D visual effects. Unlike mixed reality headsets, which blend virtual and real - world elements, VR headsets focus exclusively on immersive virtual environments.

#### Key Components
The device typically includes:
- **Display device**: Provides the visual output.
- **Lens**: Enhances the field of view and depth perception.
- **Strap**: Secures the device to the wearer's head.
- **Headphones** (often included): For audio output.
- **Gyroscope**: For motion tracking and orientation detection.

#### Notable Models and Brands
- **Oculus**: A brand of VR hardware and software, with its first product line launched in 2012. The Oculus Rift, a standalone VR headset, was released in 2016.
- **Valve Index**: A virtual reality headset developed by Valve Corporation, designed for high - performance VR experiences.
- **Standalone VR headsets**: Devices that integrate all necessary components (processing, display, sensors) into a single unit, eliminating the need for external computers.

#### Usage and Technology
Virtual reality headsets rely on **stereoscopy** to create 3D visuals, presenting two slightly offset images to each eye to simulate depth. They may also use motion sensors (like gyroscopes) to track head movements and adjust the virtual environment in real time. Some models, such as smartphone - based VR headsets, utilize a smartphone as the primary processing and display unit, reducing costs and increasing accessibility.
