Enhancing Social Life with Path Solvers: Rendezvous without Constraints on Meeting Place and Time

This paper presents a novel approach to help rendezvous between a group of people by means of their own mobile device. The group is dynamically created and consists of pedestrians who take part to a common activity, share a common context and have some kind of social relationship. When the rendezvous is called by a group member, he/she becomes the group leader and a light-weight path-solving algorithm guides all the other group members right away to their leader, who is not constrained to wait in a predefined meeting place, as he becomes the dynamic target of the path solver.
