Recent developments in information and positioning technologies, converging into portable devices offer new opportunities not only for tracking tourist movements, but also for interactive description and development of experiences. In this paper, we asses the usefulness of a small GPS-GSM device to track tourist movements on a Danish island dominated by summer house tourism, supported by a central database and Internet-based visualisation. Of equal importance to the technical issues, found to work as expected, was the psychological issues related to recruiting participants and make them share their impressions and provide information on their in-situ decisions.
