  • Perci: Pervasive service Interaction with the internet of things
    IEEE Internet Computing, 2009
    Co-Authors: Gregor Broil, Enrico Rukzio, Massimo Paolucci, Albrecht Schmidt, Matthias Wagner, Heinrich Hussmann
    Abstract:

    The advancement of ubiquitous computing technologies has greatly improved the availability of digital resources in the real world. Here, the authors investigate Mobile Interaction with tagged, everyday objects and associated information that's based on the Internet of things and its technologies. Their framework for integrating Web services and Mobile Interaction with physical objects relies on information typing to increase interoperability. Two prototypes for Mobile Interaction with smart posters build upon this framework to realize multi-tag Interaction with physical user interfaces. The authors' evaluation identifies usability issues regarding the design of physical Mobile Interactions, interfaces, and applications.

  • collect drop a technique for multi tag Interaction with real world objects and information
    Ambient Intelligence, 2008
    Co-Authors: Gregor Broll, Enrico Rukzio, Massimo Paolucci, Matthias Wagner, Markus Haarlander, Albrecht Schmidt
    Abstract:

    The advancement of Ubicomp technologies leverages Mobile Interaction with physical objects and facilitates ubiquitous access to information and services. This provides new opportunities for Mobile Interaction with the real world, but also creates new challenges regarding the complexity of Mobile applications, their Interaction design and usability. In order to take advantage of this potential beyond simple Interaction with single objects and tags, this paper investigates Mobile Interaction with multiple objects, tags and associated information. It introduces Collect&Drop as a generic technique for Multi-Tag Interaction that supports the collection, storage and management of information from the real world as well as its usage with different services. This paper describes the concept, architecture and Interaction design of Collect&Drop and presents a user study that evaluates its features.

  • collect drop a technique for physical Mobile Interaction
    2008
    Co-Authors: Gregor Broll, Enrico Rukzio, Massimo Paolucci, Matthias Wagner, Markus Haarlaender, Albrecht Schmidt
    Abstract:

    The proposed demonstration presents Collect&Drop, a new technique for Physical Mobile Interaction with the real world, its objects and associated information. Collect&Drop is integrated with the PERCI framework to interact with Web Services through the Interaction with real world objects. By supporting Physical Mobile Interaction techniques such as Touching or Pointing, the framework tries to make Mobile service Interaction more intuitive and shift its focus from Mobile devices to augmented physical objects. The demonstration will put a focus on the Mobile Collect&Drop-client and complimentary posters for Mobile ticketing that are augmented with NFC-tags and visual markers.

  • Mobile Interaction with the real world an evaluation and comparison of physical Mobile Interaction techniques
    Ambient Intelligence, 2007
    Co-Authors: Enrico Rukzio, Karin Leichtenstern, Gregor Broll, Albrecht Schmidt
    Abstract:

    Mobile devices are more and more used for Mobile Interactions with things, places and people in the real world. However, so far no studies have discussed which Interaction techniques are preferred by users in different contexts. This paper presents an experimental comparison of four different physical Mobile Interaction techniques: touching, pointing, scanning and user-mediated object Interaction. To evaluate these techniques across different scenarios and to collect real usage data, four prototypes were implemented: a system for Mobile Interaction in smart environments, a Mobile tourist guide, a Mobile museum guide and a prototype for Mobile Interaction with advertisement posters. In each setting an experimental comparison was performed. Based on the results of these studies, which involved over 60 participants in total, advantages and disadvantages of these Interaction techniques are described. Context-specific user preferences are presented for the Interaction techniques, to help application designers and developers decide which Interaction technique(s) to integrate into their application and which consequences this decision has.

  • supporting Mobile service usage through physical Mobile Interaction
    IEEE International Conference on Pervasive Computing and Communications, 2007
    Co-Authors: Gregor Broll, Enrico Rukzio, Massimo Paolucci, Matthias Wagner, Sven Siorpaes, John Hamard, Albrecht Schmidt
    Abstract:

    Although Mobile services can be used ubiquitously, their employment and the Interaction with them are still restricted by the constraints of Mobile devices. In order to facilitate and leverage Mobile Interaction with services, we present a generic framework that combines semantic Web service technology and physical Mobile Interaction. This Interaction paradigm uses Mobile devices to extract information from augmented physical objects and use it for a more intuitive and convenient invocation of associated services. For that purpose, the presented framework exploits Web service descriptions for the automatic and dynamic generation of customizable user interfaces that support and facilitate physical Mobile Interaction. This generic approach to Mobile Interaction with services through the Interaction with physical objects promises to meet the complementary development of the Internet of things. A user study with a prototype application for Mobile ticketing confirms our concept and shows its limits

  • Mobile Interaction with static and dynamic nfc based displays
    Human-Computer Interaction with Mobile Devices and Services, 2010
    Co-Authors: Robert Hardy, Enrico Rukzio, Paul Holleis, Matthias Wagner
    Abstract:

    This paper reports on a development framework, two prototypes, and a comparative study in the area of multi-tag Near-Field Communication (NFC) Interaction. By combining NFC with static and dynamic displays, such as posters and projections, services are made more visible and allow users to interact with them easily by interacting directly with the display with their phone. In this paper, we explore such Interactions, in particular, the combination of the phone display and large NFC displays. We also compare static displays and dynamic displays, and present a list of deciding factors for a particular deployment situation. We discuss one prototype for each display type and developed a corresponding framework which can be used to accelerate the development of such prototypes whilst supporting a high level of versatility. The findings of a controlled comparative study indicate, among other things, that all participants preferred the dynamic display, although the static display has advantages, e.g. with respect to privacy and portability.

  • an experimental comparison of physical Mobile Interaction techniques touching pointing and scanning
    Ubiquitous Computing, 2006
    Co-Authors: Enrico Rukzio, Albrecht Schmidt, Karin Leichtenstern, Vic Callaghan, Paul Holleis, Jeannette Chin
    Abstract:

    This paper presents an analysis, implementation and evaluation of the physical Mobile Interaction techniques touching, pointing and scanning. Based on this we have formulated guidelines that show in which context which Interaction technique is preferred by the user. Our main goal was to identify typical situations and scenarios in which the different techniques might be useful or not. In support of these aims we have developed and evaluated, within a user study, a low-fidelity and a high-fidelity prototype to assess scanning, pointing and touching Interaction techniques within different contexts. Other work has shown that Mobile devices can act as universal remote controls for Interaction with smart objects but, to date, there has been no research which has analyzed when a given Mobile Interaction technique should be used. In this research we analyze the appropriateness of three Interaction techniques as selection techniques in smart environments.
