Designing novel and meaningful interactions in the domain of Augmented Reality (AR) requires an efficient and appropriate methodology. A user centered design process requires the construction and evaluation of several prototypes with increasing technical fidelity. Although the main content of the application can already be conveyed with prerendered video, one of the main interactions in AR - The user-selected viewpoint - is only available in a very late stage. We propose the use of panoramic 360? video for scenario based user evaluation, where the user can select his point of view during playback. Initial users report a high degree of immersion in the constructed scenario, even for handheld AR.
