Passthrough
see-through view, video passthrough, color passthrough, camera passthrough(으)로도 알려짐
Passthrough shows you a live camera view of your real surroundings inside a headset, so you can see your room, find your controllers or mix virtual objects with the real world.
A VR headset covers your eyes, so you cannot see the room directly. Passthrough solves this by feeding images from the headset's outward-facing cameras to the displays in real time. The result is a video view of your surroundings that you see without taking the headset off.
Black-and-white versus color
Earlier and lower-cost implementations use grayscale cameras and were mainly meant for quick checks, such as finding your drink or drawing a boundary. The PlayStation VR2 offers this kind of see-through view. Newer headsets like the Meta Quest 3 and Meta Quest 3S use color cameras and depth sensing to produce a much more usable picture. High-end devices such as the Apple Vision Pro and the Samsung Galaxy XR aim for high-resolution, low-latency passthrough suitable for long sessions.
What it enables
- Quick awareness of your room without removing the headset.
- Mixed reality apps that place virtual objects on your real table or walls.
- Productivity setups with virtual monitors floating in your real space.
Limits
Passthrough is still a camera image. Fine text, such as a phone screen, can look soft, low light adds noise, and very close objects may appear slightly distorted.
