'''Passthrough''', also known as "video passthrough", is a capability of mixed reality/virtual reality headsets where they can display the outside world by using cameras to the user. This makes it a sort of pseudo-augmented reality.

'''Passthrough''' is a capability of a mixed reality headset to show the outside world to the user by using cameras to pass through a video feed. It is also known as "video passthrough". This makes it a sort of pseudo-augmented reality or some people call it mixed reality.

Video passthrough was popularized by the [[Lynx R1]].

Video passthrough was popularized by the [[Lynx R1]] and furthered by the [[Quest 2]] and [[Quest Pro]].

One of the difficulties of getting this right is the positional difference between cameras on the outside of a headset and the eyes of the user. So the image has to go through a distortion process. On the [[Quest Pro]] and [[Quest 3]], this uses a neural network. Other devices potentially also use a neural network.
