interaction design

NFC(Near Field Communication) is how the mobile phone industry calls RFID for phones: A reader is build into the mobile phone and acts as a tag at the same time. This leads to number of use cases (Nokia) as: the hip teen can download music (Nokia) related to a movie by reading the tag on the poster. or: the craftman, who needs to read meters (Nokia). French Telecom has also a nice movie on application scenarios like paying with the phone or Location-Based Services.

Interesting is the feature that allows phones to read tags and be a tag at the same time. This reminds me of an interesting interface solution by Rekimoto at Sony's CSL: he is suggesting FEEL, a gesture-based interaction to establish communication between to networked devices. So the pairing doesn't need to be performed.

Another interesting interaction method was also developed by Rekimoto: Pick-and-Drop. With the quite natural gesture of picking screen-based objects (data) through a pen and dropping these objects on other screen-based computers an easy way of transfering data could be achieved.

Mathias Dahlström developed in his thesis at IDII a gesture-based language for sharing data (in his case: music). I particulary like his idea of sending data by making a throwing gesture towards the receiver.
