The dominant metaphor for RFID interaction is touch where the gesture of touching or the contact between two objects is seen as a suitable model for near field interactions. However touch may be a limiting metaphor for RFID interfaces, in that it doesn’t suggest the possible range of interactions that RFID affords.
Three recent Touch projects suggest different senses as metaphors for physical RFID interaction:
Silje Søftings Pling Plong project uses an eye as the ‘reader’ of audiobook tokens.
Bilal Chaudhry & Marius Johansen’s project Le Chef uses a huge tongue giving the appearance that the chef character is tasting the food tokens that are placed on it.
Sara Johansson’s Sniff project uses the nose of a toy dog as the reader, giving the impression that the dog is sniffing token objects.
Are these other human senses more successful than touch in creating the right kind of metaphors for RFID interaction? Can we use human senses as metaphors to create a richer design space for RFID, or does the inspiration have to come from somewhere else?
