In this paper, we present the first results of a research aiming at developing an intelligent agent able to interact with users in public spaces through a touch screen or a personal device. The agent communication is adapted to the situation at both content and presentation levels, by generating an appropriate combination of verbal and non-verbal agent behaviours.
