CharmMe is a mobile social discovery application that helps people meet each other during events. The application blends physical and digital proximity to help you connect with with other like-minded individuals. Armed with RFID sensors and a model of how the Lab works, CharmMe determines who you should talk to using information including checking in to conference talks or "liking" projects using QR codes. In addition, possible opening topics of conversation are suggested based on users' expressed similar interests.
