Watch the other side of the world with "Mixed AR" Today, everything is digitalized, and even the scenery in front of our eyes is scanned in real time, and the world on the other side exists simultaneously. What would we find in "reality" if we were to see that world, which we don't usually see? In this work, you can experience it using VR goggles for smartphones with camera. In your left eye, there is an image of the real world, in your right eye, the world on the other side of the world is projected in the blue space. They are superimposed and perceived in the brain from the retina onwards. We can see both sides of the world through the camera, and the world behind it. By observing at the same time, we may be able to have a new perspective.
