Presentations at the 4th International Symposium on LBS and TeleCartography

I am in Hong-Kong for the 4th International Symposium on LBS and TeleCartography where I introduced two different works in the Mobile Users Analysis track. First I presented my paper “Understanding of Tourist Dynamics from Explicitly Disclosed Location Information” that describes the early results of the Tracing the Visitor’s Eye project based with data collected in the Province of Florence. I intended to communicate the complementary perspective new types of digital footprints can bring to mobility, urban and travel studies. The content of other presentations in the session (mainly Ahas Rein‘s Mobile Positioning: New Perspective in GIS and Geographical Studies. Ahas chairs an upcoming workshop on social positioning method) that are based GSM network data, helped situate the originality of my approach based on act of communications “I was here” instead of passive, implicit mobility data. It means also no issues of scalability, infrastructure and negotiations with operators. I suggested the idea the explicitly disclosed location data can help inform the design of LBS (e.g. help define area of attention of people, the area of influence of objects, and the granularity of information). Finally, of course, I mentioned the feedback loop generated by people’s past interactions with the urban environment and infrastructure that become recommendations and impact the perception of the space.

Later, I presented (on behalf of the WikiCity team) the main concepts and design of the MIT SENSEable City Lab current project WikiCity. Without getting into the technical details, I stressed the importance of developing a real-time mapping of city dynamics for people to become actuators and prime actors of the cityspace. The scenarios of WikiCity is based on the fusion of 3 elements agents (individuals, companies, local authorities…), the environment (architecture, infrastructure, climate…) and technology features (opportunities and limitation positioning and sensing technologies. A main challenge is to provide a common format for interchange of realtime location-based data and to communicate the information to multi-modal interfaces (close to the person such as mobile/fixed devices, embedded in the infrastructure, vehicles (public transport, individual cars).
