The project is creating a novel approach to the curation of ambient music played in venues through Near Field Communications (NFC) enabled check-ins. The system know as ‘CheckinDJ’ utilises NFC enabled objects linked to individual venue patrons social network accounts to create a dynamic music play-list for the venue based on the combined preferences of the customers currently present. To enhance the usability of the system we employ gameful design to encourage and maintain particpation amongst users.
