Micro-Interactions With NFC-Enabled Mobile Phones
This paper coins the term micro-interactions to refer to the class of small exchanges between devices that occur almost instantaneously. For example, a mobile payment using Near-Field Communication (NFC) is a micro-interaction. The arrival of NFC on smart phones makes possible a wide array of applications using micro-interactions, from sharing photos between a phone and a TV to checking a car into a valet parking service by touching two phones. This paper addresses the challenge of how to create intuitive, frictionless micro-interactions that require no pre-configuration for a large class of applications.
