The increasing number of media faĂ§ades in urban spaces offers great potential for interaction. Due to their size and physical properties interacting with them directly by touching them is not possible. In this paper, we present a sensor-based approach, which relies on the GPS, compass and accelerometer data of a mobile device to control a pointer on large-scale urban displays, such as media faĂ§ades. We calculate the pointing direction based on the location and orientation of the mobile device and display a preview of the content around the current cursor position to overcome the limitations of current GPS sensors. We further report on an initial user evaluation, revealing the presented approach as accurate and easy-to-use.
