P3 Systems

Overview of the challenges of P3 systems or `people to people to geographical spaces', also called placecasting, at http://ieeexplore.ieee.org/search/wrapper.jsp?arnumber=1510603

The availability of technologies enables a new class of location-aware information systems that link people-to-people-to-geographical-places (P3 systems). P3 systems can strengthen the relationship between social networks and physical places. They can also help individuals leverage location information to make new social ties and coordinate interactions that reinforce existing ties. Using the P3 systems framework, we describe the design space for location-aware community systems and important socio-technical challenges and opportunities.
