Modeling NFC-triggered user interactions with simple services in a smart environment

NFC is an emerging wireless technology that can enable users to interact with smart objects in a smart environment. NFC applications have been developed to provide services like ticketing, access control, tourism information extension, voucher redemption and contactless payment. The interaction technique is a sort of "tap-and-go" as it is currently employed in smartcard usage for travel operations and workspace access/logging. Employing a recently introduced framework for human interaction with mobiquitous services, we present a model of NFC-triggered user interactions with simple context-awareness services in a smart environment. The rationale is to provide a conceptual tool for both an appropriate communication among NFC ecosystem stakeholders and the interface design of NFC apps with a generic applicability. Lastly, we discuss the application of the model in a project which required the design of NFC-based interactions with services for car parking management in a city area
