Mobile devices become smaller and more powerful with each generation distributed. Because of the tiny enclosures the interaction with such devices o®ers limited input capabilities. In contrast there are hardly any mobile phones purchasable that do not have a built-in camera. We developed a concept of an intuitive interaction technique using optical inertial tracking on mobile phones. The key of this concept is the user moving the mobile device which results in a moving video stream of the camera. The direction of the movement can be calculated with a suitable algorithm. This paper outlines the algorithm Projection Shift Analysis developed to run on mobile phones.
