MODO I, II : Reactive sculptures with RFID This project aims to present the representation and aesthetics of Radio Frequency Identification (RFID) technology as a method of creating rich user experiences and active participation in public space. In this experimental project, the unique ID number sets of RFID tags are used to generate tangible modules and associated patterns of sound. Modules combine to produce an interactive sculpture responsive to a group of participants. Based on these results we outline a problem space for designing ambient and direct forms of interaction with light and sound in urban environments.
