The great success of wearables and smartphone apps for provision of extensive physical workout instructions boosts a whole industry dealing with consumer oriented sensors and sports equipment. But with these opportunities there are also new challenges emerging. The unregulated distribution of instructions about ambitious exercises enables unexperienced users to undertake demanding workouts without...
In recent years, the importance of location-based services and indoor positioning systems increased significantly for both, research and industry. Visual localization systems have the advantage of not depending on dedicated infrastructure and thus they are interesting for navigation within buildings. While there are already approaches which are using pre-recorded databases of reference images to obtain...

Immer mehr Anwendungen und digitale Dienste verlagern sich in die Cloud, insbesondere im Unternehmenskontext. Dadurch entstehen neue Anforderungen an die Sicherheit. Zwar bieten viele Systeme im Web ein detailliertes Sicherheitskonzept, der Zugang zu diesen Diensten wird jedoch meist durch ein einfaches Kennwort geschützt. Insbesondere im Unternehmensumfeld werden hohe Anforderungen an ein sicheres...
Due to the increasing popularity of location-based services, the need for reliable and cost-effective indoor positioning methods is rising. As an alternative to radio-based localization methods, in 2011, we introduced MoVIPS (Mobile Visual Indoor Positioning System), which is based on the idea to extract visual feature points from a query image and compare them to those of previously collected geo-referenced...
With the increasing computational power of mobile devices and the increase in the usage of ordinary location-based services, the area of indoor location-based services is of growing interest. Nowadays indoor location-based services are used mainly for personalized information retrieval of maps and points of interest. Advanced location-based functionality often suffers from imprecise positioning methods...
