Trust is a concept used throughout our daily lives. We give trust to friends, colleagues and strangers. We also give trust to the technical artifacts we use in our everyday lives. We must also rely on the services we use to work the way we expect them to. There is plenty of research on trust in e-commerce and online banking on website based platforms. What is missing is research on how we give trust to mobile map applications (and mobile applications in general), and how this trust, or lack of trust, affect our use of map applications in everyday life. We will also use a model of trust to see if we can get a deeper understanding of this trust.
