Constructed Narratives is a tangible social interface designed for use in public spaces where people have the opportunity to encounter the game and subsequently learn about each other. The hardware and software system architecture developed for this project could be applied for experimental computer-based interfaces for several human computer interaction domains including collaborative learning (CSCL), and collaborative design activities in the tradition of computer supported collaborative work (CSCW). The current domain explored for Constructed Narratives is that of computer systems designed to enable shared experience through play, or computer supported collaborative play (CSCP).
