Abstract We present a novel system allowing in-situ content creation for mobile Augmented Reality in unprepared environments. This system targets smartphones and therefore allows a spontaneous authoring while in place. We describe two different scenarios, which are depending on the size of the working volume and consequently use different tracking techniques. A natural feature-based approach for planar targets is used for small working spaces whereas for larger working volume a panoramic based rotation tracking is deployed. Both are integrated into one system allowing the user to use the same interaction for creating the content applying a set of simple, yet powerful modeling functions for content creation. The resulting AR content can be shared with other users using a dedicated content server or kept in a private inventory for later use.
