    Acknowledgments

    This is a thesis in fulfillment of the requirements for the Diplom-Medieninformatik degree at the Department of Media Informatics at Ludwig-Maximilians-Universität, München, Germany. The research study was hosted by the Institute for Creative Industries and Innovation at the Queensland University of Technology (QUT), Brisbane, Australia.

    First of all I thank my Australian supervisor Dr Marcus Foth for his support, advice and guidance during the entire period of this thesis. Sharing his senior intellectual and practical knowledge helped me to understand and apply important research processes in multi- disciplinary academic projects such as this study. I also thank him for his mentorship, as well as encouraging, supporting, and co-authoring my publications related to the key results of this study in academic journals and international conference papers.

    I would like to thank Prof. Greg Hearn, the Director of the Institute for Creative Industries and Innovation (iCi), for providing a scholarship to support my study and stay at QUT. Thanks also to the German National Academic Foundation (Studienstiftung des deutschen Volkes) for providing additional financial support that allowed me to attend the Locative Media Summer Conference in Siegen, Germany to present this study. My special appreciation goes to Dr Helen Klaebe for warmly taking care of me and her emotional as well as social support during my entire stay in Brisbane and at QUT. I would like to thank Alexander De Luca for supervising the technical parts of my work. Furthermore I thank Fiona Crawford, Natalie Carr and all of the previously mentioned people for their critical and thorough proof reading.

    Finally, I would like to express my very deepest gratitude and dedicate this thesis to my parents Mladen and Marija Bilandzic, as well as my brother Marin and my sister Ana, who always gave me infinite support, love, and patience for all my personal as well as professional activities. I love you.

    Abstract

    This thesis presents social requirements and design considerations from a study evaluating interactive approaches to social navigation and user-generated information sharing in urban environments using mobile devices. It investigates innovative ways to leverage mobile information and communication technology in order to provide a social navigation platform for residents and visitors in and for public urban places.

    Through a design case study this work presents CityFlocks, a mobile information system that offers an easy way for information-seeking new residents or visitors to access tacit knowledge from local people about their new community. It is intended to enable visitors and new residents in a city to tap into the knowledge and experiences of local residents in order to gather information about their new environment. Its design specifically aims to lower existing barriers of access and facilitate social navigation in urban places. In various user tests it evaluates two general user interaction alternatives – direct and indirect social navigation – and analyses which interaction method works better for people using a mobile device to socially navigate urban environments. The outcomes are relevant for the user interaction design of future mobile information systems that leverage the social navigation approach.
