LAST MINUTE: a Multimodal Corpus of Speech-based User-Companion Interactions
TL;DR: The recordings in this data collection are taken from a WOZ experiment that allows to investigate how users interact with a companion system in a mundane situation with the need for planning, re-planning and strategy change.
Proceedings Article

J"org Frommer,Bernd Michaelis,Dietmar R"osner,Andreas Wendemuth,Rafael Friesen,Matthias Haase,Manuela Kunze,Rico Andrich,Julia Lange,Axel Panning,Ingo Siegert +10 more
TL;DR: First results are reported about first attempts to automatically and manually analyze the different modes with respect to emotions and affects exhibited by the subjects in the LAST MINUTE corpus.

Dmytro Prylipko,Dietmar F. Rösner,Ingo Siegert,Stephan Günther,Rafael Friesen,Matthias Haase,Bogdan Vlasenko,Andreas Wendemuth +7 more
TL;DR: The presented investigations coherently support age-dependence of both expressiveness and problem-solving ability in communication with dialog systems, and induces design rules for future automatic designated “companion” systems.
Book ChapterDOI
Intentionality in interacting with companion systems: an empirical approach
TL;DR: A WOZ experiment is reported about with a carefully designed scenario that allows to investigate how users interact with a companion system in a mundane situation with the need for planning, re-planning and strategy change.
Book ChapterDOI
Message oriented middleware for flexible wizard of Oz experiments in HCI
TL;DR: This paper focuses on experimental WOZ designs, their realisation within the SEMAINE framework and lessons learned from deploying the implemented solutions as the basis for ongoing controlled experiments with 120 subjects.
