GroundCam: A Tracking Modality for Mobile Mixed Reality

Anywhere Augmentation pursues the goal of lowering the initial investment of time and money necessary to participate in mixed reality work, bridging the gap between researchers in the field and regular computer users. Our paper contributes to this goal by introducing the GroundCam, a cheap tracking modality with no significant setup necessary. By itself, the GroundCam provides high frequency, high resolution relative position information similar to an inertial navigation system, but with significantly less drift. When coupled with a wide area tracking modality via a complementary kalman filter, the hybrid tracker becomes a powerful base for indoor and outdoor mobile mixed reality work.
