Geofencing 2.0: Taking Location-based Notifications to the Next Level Sandro Rodriguez Garzon Service-centric Networking Telekom Innovation Laboratories, TU-Berlin Berlin, Germany [email protected] Bersant Deva Service-centric Networking Telekom Innovation Laboratories, TU-Berlin Berlin, Germany [email protected] ABSTRACT Recently, Location-based Services (LBS) became proactive by supporting smart notifications in case the user enters or leaves a specific geographical area, well-known as Geofen- cing . However, different geofences cannot be temporally re- lated to each other. Therefore, we introduce a novel method to formalize sophisticated Geofencing scenarios as state and transition-based geofence models. Such a model considers temporal relations between geofences as well as duration con- straints for the time being within a geofence or in transition between geofences. These are two highly important aspects in order to cover sophisticated scenarios in which a notifica- tion should be triggered only in case the user crosses multiple geofences in a defined temporal order or leaves a geofence after a certain amount of time. As a proof of concept, we introduce a prototype of a suitable user interface for design- ing complex geofence models in conjunction with the corres- ponding proactive LBS.

Information Interfaces and Presentation (e.g. HCI): Miscellaneous INTRODUCTION Over the last years, mobile devices such as smartphones or tablets became an integral part of everyone’s daily life. As envisioned by Mark Weiser , those technologies are seamlessly integrated into the environment by making use of sensing technologies and sophisticated ambient services. Thereby, the mobile devices are expected to act within an in- telligent environment in which they are supposed to support the user by adapting its capabilities towards the situational needs .
