Digital Graffiti - a Comprehensive Location-Based Travel Information System

Description

Digital Graffiti is an open, extensible platform for mobile location-based services that context-sensitively supports travelers using public transportation on their individual travel routes across transportation companies. The personal mobile phone of each traveler automatically checks for connecting transportation options, shows their current locations and triggers re-planning on delays such that the mobile phone appears as an intelligent companion throughout the journey. It additionally enables its users to produce user-generated location-bound content for other travelers in order to enrich navigation in a self-organizing wag, e.g., for more appropriate instructions for handicapped people (blind people guide blind people). This paper sketches the basic architecture of the system and gives an impression on its potentials.
