Design and Evaluation of Techniques for Mobile Interaction with Dynamic NFC-Displays
In Proceedings of the 5th International Conference on Tangible, Embedded and Embodied Interaction (TEI 2011), Funchal, Portugal, January 23 - 26, 2011

Near Field Communication (NFC) is a technology for mobile, touch-based interaction with tagged objects that can serve as physical user interfaces (UI). Dynamic NFC-displays use a grid of NFC-tags as a physical UI and combine it with a projected application UI to enable direct interactions between mobile devices and large screens. In this paper, we explore the design of interaction techniques for dynamic NFC-displays beyond the common touch-select interaction with single tags and evaluate them with an NFC-pinboard prototype. A user study confirms the general preference for the simple touch-select, but also shows that other techniques can provide alternatives, e.g. to implement interactions for which users want to feel more in control.
