A VR headset is a computer component designed for immersion, featuring high-resolution displays for stereoscopic 3D visuals, lenses to direct the images, and motion sensors (gyroscopes, accelerometers) to track head and body position for interactive experiences. It also uses input devices like controllers for interaction and integrated audio for spatial sound, all driven by a powerful computer with a dedicated graphics processing unit (GPU) to render the virtual world with minimal latency.

Core Components

Display: Integrated screens that project stereoscopic images, with a slightly different view for each eye to create the perception of depth.

Lenses: These lenses focus and shape the images from the screens, filling the user's field of view and contributing to a convincing 3D effect.

Motion Sensors (Tracking): Gyroscopes and accelerometers within the headset track the user's head movements, allowing the virtual environment to update in real-time to match physical movements.

Audio System: Built-in headphones or audio drivers provide spatial audio, creating a 3D soundscape that enhances immersion.

Input Devices: Handheld controllers, gloves, or other devices are used to interact with the virtual world by tracking hand and finger movements.

The computer processes the VR software, sending stereoscopic images to the headset's display. The headset's lenses focus these images, creating a 3D virtual world that fills the user's vision. When the user moves their head or hands, the motion sensors in the headset and input devices detect these movements. The computer, powered by the GPU, updates the visuals in real-time based on the sensor data, ensuring the virtual world aligns with the user's physical movements. Spatial audio and, in some cases, haptic feedback (from controllers) further enhance the feeling of being present in the virtual environment.
