We present a novel approach for creating and exploring annotations in place using mobile phones. The system can be used in large-scale indoor and outdoor scenarios and offers an accurate mapping of the annotations to physical objects. The system uses a drift-free orientation tracking based on panoramic images, which can be initialized using data from a GPS sensor. Given the current position and view direction, we show how annotations can be accurately mapped to the correct objects, even in the case of varying user positions. Possible applications range from Augmented Reality browsers to pedestrian navigation.
