The paper describes the use of cultural probes in a design process that involves elderly people and it explores some their implications and effects. We describe a project where probes were used in a different way compared to their first description by Gaver. We show the way we build our probes and our use of them and we highlight some interesting effects that we expirienced in the field. This expirience suggests that Cultural probes might help in establishing a proper hospital mood in the adoption and acceptance of new technologies yet to be implemented. This point help us look at the concept of hospitality in a much practical way and it suggests the idea that hospital mood can be – if not engineered – at least favoured, triggered and established by diluting the “visit of the stranger”.
