This is the basic concept that I think the project should be created from. A container shaped hub is the main, static object. This will sit in the room when most social interaction takes place, usually the living room. Each user will have an object which embodies their playlist as a physical item. This will be something small which they can carry around without being obtrusive. When users enter the room they can place their object into the hub. The hub will read each object and know what playlist each one contains. It will then merge all the contained playlists into one large playlist and play each track in a shuffled order. This allows tracks from each playlist to be heard. This will be the basic operation of the device. Currently there will be no control over playback, only volume which will be provided by the users own speaker system. This may change when my cultural probes are returned and I can see what information they contain.
