Perception in Multimodal Dialogue Systems

The IEEE Tutorialand ResearchWorkshopon Perceptionand InteractiveTe- nologies for Multimodal Dialogue Systems (PIT 2008) is the continuation of a successful series of workshops that started with an ISCA Tutorial and Research WorkshoponMultimodalDialogueSystemsin1999.Thisworkshopwasfollowed by a second one focusing on mobile dialogue systems (IDS 2002), a third one exploring the role of a?ect in dialogue (ADS 2004), and a fourth one focusing on perceptive interfaces (PIT 2006). Like its predecessors, PIT 2008 took place at Kloster Irsee in Bavaria. Due to the increasing interest in perceptive interfaces, we decided to hold a follow-up workshop on the themes discussed at PIT 2006, but encouraged aboveallpaperswithafocusonperceptioninmultimodaldialoguesystems.PIT 2008received37 paperscoveringthe following topics (1) multimodal and spoken dialogue systems, (2) classi?cation of dialogue acts and sound, (3) recognitionof eye gaze, head poses, mimics and speech aswellascombinationsofmodalities, (4) vocal emotion recognition, (5) human-like and social dialogue systems and (6) evaluation methods for multimodal dialogue systems. Noteworthy was the strong participation from industry at PIT 2008. Indeed, 17 of the accepted 37 papers come from industrial organizations or were written in collaboration with them.
