We present a new mobile application SocialCRC to simplify the process of coordinating an impromptu rendezvous. By considering contextual information and the social relationships between the attendants of a rendezvous, SocialCRC can identify a more satisfactory rendezvous point. In this study, we deploy SocialCRC in the context of a dinner rendezvous. A preliminary user evaluation indicates that SocialCRC can offer satisfactory results for the most influential person involved in the coordination process. It also provides an acceptable solution for the whole group, without diminishing the satisfaction of the least influential person in the group.
