In this paper we describe and discuss a requirements analysis that aimed at informing the design of a pervasive application. We approached the requirements analysis by conducting a survey and a covered field observation to understand tourists on a bicycle trip. Both studies yielded significantly different results. We therefore join arguing that studies of different types should be mixed in order to get a complete understanding of the target situations. We showcase that the field observation, although supposedly being less valid than the survey, yielded important results that we would not have found by concluded the survey only. Our field observation also highlights that there is a need for guidelines about ethics when evaluating pervasive applications in the field.
