Physical mobile interaction with dynamic physical object

Human-Computer Interaction – INTERACT 2011

Abstract. The Keystroke-Level Model (KLM) is a model for predicting the execution time of routine tasks. Initially, it had been devised for standard keyboard-desktop settings but an extension of this model for interactions with mobile phones has been described by Holleis et al. [10]. We propose a considerable update of this KLM focusing on NFC-based applications and interactions which are continuously gaining interest. Insufficiencies within the previous model regarding operators for Pointing, Mental Acts, and System Response Time are treated. We present the results of several studies conducted in order to update the values of these operators. A specific focus is put on the differences between static (NFC tags behind a printed poster or object) and dynamic interfaces (tagged displays or projections). Finally, we validate our results by modeling two applications with the former and the proposed model. The latter performed consistently better when compared with measurements from real user interaction data.

“…That way, tags can be dynamically mapped to the UI elements of different applications. Vetter et al [18] and Hardy et al [8] have created and refined the first dynamic NFC-displays that use a grid of NFC-tags for the interaction with an application UI that is projected onto this interactive surface. Similarly, Ramírez-González et al [11] have combined a grid of NFC-tags and a projected application UI to build an interactive NFC-panel.…”

Touch to Play -- Exploring Touch-Based Mobile Interaction with Public Displays

Abstract-Mobile interactions with public displays are often indirect and not very convenient for multiple users at the same time. In this paper we use the physical, touch-based interaction with Near Field Communication (NFC) to investigate direct mobile interactions with public displays for multiple users. For that purpose, we adopt the Whack-a-Mole game for dynamic NFC-displays, which combine the physical interaction with NFCtagged objects and the visual output capabilities of public displays. We show that a grid of NFC-tags can be used to implement direct mobile interaction with public displays in general and a highly interactive multiplayer game in particular. Our study shows that users appreciate this physical, NFC-based mobile interaction, although technical advances are still necessary in order to improve its recognition rate of about 70%. The study also indicates that users are willing to interact with large displays in public, but prefer private or semi-public places, where their interactions attract less attention.

“…That way, tags can be dynamically mapped to the UI elements of different applications. Vetter et al [17] and Hardy et al [5] have created and refined the first dynamic NFC-displays that use a grid of NFC-tags for the interaction with an application UI that is projected onto this interactive surface.

“…The dynamic NFC-display of Vetter et al [17] has supported bounding box selection and path selection. Hardy et al [5] have added new interaction techniques for their Touch & Interact-approach: Hovering shows information about a tag on a mobile device when holding them close to each other.…”

Design and evaluation of techniques for mobile interaction with dynamic NFC-displays

Proceedings of the Fifth International Conference on Tangible, Embedded, and Embodied Interaction

et al. 2010

Near Field Communication (NFC) is a technology for mobile, touch-based interaction with tagged objects that can serve as physical user interfaces (UI). Dynamic NFCdisplays 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 touchselect 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.
