When interacting with spoken and multimodal dialogue systems, it is often difficult for users to understand and influence how their input is processed by the system. In this paper, wedescribe how these problems were addressed in the multimodal real-estate dialogue systemAdApt. During the course of a dialogue, the user's contraints are translated into symbolicicons that are visualized on the screen and can be manipulated by drag-and-drop operations.Users are thus given a clear picture of how their utterances are understood, and are given atransparent means of controlling the interaction with the system.
