Demo of the RHIFID speakers developed at CIID. Using a combination of RFID technology, Processing and Arduino, the speakers work as location aware controllers, allowing the user to interact with music and the environment by moving the speakers around.Paragraph. Putting the two speakers together triggers the speakers into playing one common song, creating a social listening experience. The RHIFID speakers can also be modified into musical creators rather than just controllers, allowing location and rotation to control such things as pitch, samples and effects.
