20 © W. Wahlster Which feature films are shown tonight on TV? Combination of Speech and Gesture in SmartKom I show you a survey of tonight's TV films. I can't find anything interesting. Then I'll go to the movies. Here you see a programme listing of the movies shown in Heidelberg today. This one I would like to see. Where is it shown? On this map all movie theatres are highlighted, that are showing "A Little Christmas Story".

21 © W. Wahlster Multimodal Input and Output in SmartKom There I would like to get a reservation. In this movie theatre a reservation is not possible. Then let's check another theatre. What about this one? This overview lists all show times for the movie "A Little Christmas Story" in the movie theatre "Castle". Here I would like to get a reservation. Please show me where you would like to be seated. I would like to get two seats here. Is this okay? Sure. I have reserved the seats. Your confirmation number is 635. You can pick up the tickets till half an hour before the show at the ticket box. Okay. Thank you. Good Bye. Good bye.

62 © W. Wahlster Burning Issues in Multimodal Interaction Multimodality: from alternate modes of interaction towards mutual disambiguation and synergistic combinations Discourse Models: from information-seeking dialogs towards argumentative dialogs and negotiations Domain Models: from closed world assumptions towards the open world of web services Dialog Behaviour: from automata models towards a combination of probabilistic and plan-based models

63 © W. Wahlster SmartKom is a multimodal dialog system that combines speech, gesture, and mimics input and output. Spontaneous speech understanding is combined with the video- based recognition of natural gestures. One of the major scientific goals of SmartKom is to design new computational methods for the seamless integration and mutual disambiguation of multimodal input and output on a semantic and pragmatic level. SmartKom is based on the situated delegation-oriented dialog paradigm, in which the user delegates a task to a virtual communication assistant, visualized as a life-like character on a graphical display.
