Two NFC interaction techniques for quickly exchanging pictures between a mobile phone and a computer

Uploading and downloading pictures between a mobile phone and a computer is still a very cumbersome process. Because of this, many users actually do not copy, move or backup their pictures onto another computer until the storage capacity of the mobile phone is reached. This paper presents the prototypes (and respective implementation details) of the touch & connect and touch & select interaction techniques. Both techniques allow the quick and easy exchange of pictures by touching the computer with the mobile device. The first interaction technique: touch & connect, allows the user to touch a computer with their mobile phone in order to establish a Bluetooth connection and initiate a file transfer between the two devices. The second interaction technique: touch & select, extends this concept and allows the selection of a specific picture or location on the computer screen by touching it with the mobile phone. The interaction techniques were implemented using Near Field Communication (NFC) tags attached to the computer and an NFC phone capable of reading those tags
