Within the ARCHEOGUIDE project, an outdoor AR cultural heritage on-site guide was developed. The GEIST project combined outdoor AR with digital storytelling in 17th century Heidelberg, Germany. To our knowledge, the first 3D maps for the mobiles, running on Nokia communicator, were developed in the Tellmaris project. Finally, the LoVEUS project creating multimedia location-based services for a variety of mobile devices. The LoVEUS project will be presented in more detail because it is a perfect system for further research and development in AR user interfaces for location-based services.en3D city modellocation-based service (LBS)Augmented reality (AR)mobile multimediamultimedia database system006book article
