Notice the reflection of Gentaro's hand and the flashlight beam in the computer generated object. In the real environment, a reflective sphere is sitting at the location of the teapot. Only precise registration allows us to know where the sphere is located in the HMD image. Here are some Quicktime movies that we have made of demonstrating our system. This movie shows the camera panning across our scene.
Landmarks come in to view and then disappear.
Notice that the virtual and real cuboids remain registered. This demonstrates the robustness of our system. This video clip shows how our system reacts to landmark obscuration. Here a hand is waved in front of the camera, hiding landmarks from the tracking system. As the landmarks reappear in the camera's view, the system quickly re-acquires them.
