Abstract-- The interface for the next generation of Unmanned Vehicle Systems should be an interface with multi-modal displays and input controls. Then, the role of the interface will not restricted to be a support of interactions between the ground operator and vehicles. Interfaces must take part in the interaction management too. In this paper, we show that recent works in pragmatics and philosophy [1] provide a suitable theoretical framework for the next generation of UV System's interface. We concentrate on two main aspects of the collaborative model of interaction based on acceptance: multi-strategy approach for generation and interpretation of communicative acts and communicative alignment.
