Real-World Tagging in the Wild: On the Usability and Accessibility of NFC-based Interactions

Abstract

With the introduction of NFC-equipped mobile phones real-world tagging technologies have become available to a wide audience. It is therefore time to investigate the usability of the mobile touch interaction paradigm in real contexts to ensure its acceptance among users. In this paper we discuss usability issues of mobile touch interactions regarding the user interface, user interactions, and the user experience. We further present results from a study on NFC interaction and a prototype to leverage the accessibility of real-world tagging technologies.
