Crumblr: Aggregation and Sharing of Spatial Content in Mobile Environments

In the growing mobile computing sector two trends are more and more wide-spread and gain further momentum: location-sensing technologies and mobile Internet access. In this paper we describe Crumblr, an application for semi-automatic capturing, aggregating and sharing spatial content in mobile environments. While existing Web 2.0 services focus mostly on points of interest or on routes, our application combines these two entities and additionally enriches them with contextual data. The result is the generation of an implicit network among people, linked via spatial information. This allows us to provide them with personalized recommendations of places, routes and related other people.
