TITLE: Multimodal interaction research at 'Tampere Unit for Computer-Human Interaction' (TAUCHI)

SPEAKER: Markku Turunen

I will present an overvirew of multimodal interaction research activities at the Tampere Unit for Computer-Human Interaction (TAUCHI). University of Tampere is one of the largest universities in Finland, with about 14.500 students. It is a full-scale university with nine schools. As a sizeable part of the School of Information Sciences, Tampere Unit for Human-Computer Interaction (TAUCHI) consists of 45 staff members. It is the largest research unit in its area in Finland and one of the largest in the world. The unit it has been identified as the "as the strongest Finnish group in HCI" in the report of Academy of the Finland. TAUCHI is further divided into four research groups, Multimodal Interaction, Emotions, Sociality, and Computing, Speech-based and Pervasive Interaction Group, and Visual Interaction research Group. I will introduce the research activities of these group, and provide some detailed examples from relevant case studies of the Speech-based and Pervasive Interaction Group.

TITLE: Die Effizienz von multimedialen Präsentationstechniken in der Kommunikation des radiologischen Befundes

SPEAKER: Franziska Franz, TU Berlin

In der Radiologie kommen heutzutage hochentwickelte Verfahren zum Einsatz, durch die das Innerste des menschlichen Körpers präzise und kontrastreich abgebildet wird. Dieses Bildmaterial ist Grundlage für den radiologischen Befund, in dem der Radiologe seine Beobachtungen beschreibt und die Beurteilung dazu abgibt.
Der überweisende Mediziner, der Empfänger des radiologischen Befundes, erhält in den meisten Fällen einen rein sprachlich- visuellen Befund in Textform. Seit Jahrzehnten erhalten Überweiser Befunde in derselben Form. Das Ausgangsmaterial für seine Therapieentscheidungen ist dasselbe geblieben, obwohl sich das Ausgangsmaterial für die Beurteilungen der Radiologen drastisch verbessert hat und sich viele neue Modellierungs- und Betrachtungsmöglichkeiten bieten.
Diese Arbeit untersucht unter kognitionspsychologischen Aspekten, ob Überweiser von einer multimedialen Präsentation der Befundinhalte, die die radiologischen Bilder einschließt, profitieren.
Ziel war es, die Effizienz von multimedialen Gestaltungstechniken in der Kommunikation des radiologischen Befundes zu prüfen. Dafür wurden zwei Formen multimedialer Befunde (analog und audiovisuell) mit dem herkömmlichen Textbefund verglichen.

TITLE: A Short History of Tabletop Research, Technologies, and Products

Christian Müller-Tomfelde

In his talk Christian will present a brief history of scientific research into interactive tabletops, associated and emerging technologies, and commercial products. As part of the introductory chapter of the upcoming Springer book about tabletops, it summarizes and visualizes a body of scientific work, identifies major advances during the past fifteen years, and thereby draws a picture of the research landscape to date. Furthermore, key innovations during this period are identified and their research impact discussed. The historical information become synthesized into a synoptic landscape including research highlights, enabling technologies, prototypes, and products. On top of this landscape, innovations are pointed out that stimulated and triggered three key transitions in research and technology. These innovations have also played a major role in leveraging ideas from a conceptual level to widespread adoption and use.

Christian Müller-Tomfelde is a researcher at the Information Engineering Laboratory of the CSIRO ICT Centre in Sydney. His expertise lies in the research area of Human Computer Interaction and Virtual and Hybrid Environments focussing on the support of co-located and remote collaboration support. His interests also include novel forms of interaction, multimodal interaction such as sound feedback. After finishing his studies in electrical engineering at the University of Hamburg-Harburg, he worked at the Center for Art and Media Technology (ZKM) in Karlsruhe. In 1997 he joined the GMD-IPSI's division AMBIENTE "Workspaces of the Future" in Darmstadt/Germany. He was involved in the i- LAND project and in the design of the roomware components of the first and second generations. In his dissertation he explored new forms of audio feedback for the collaborative interaction in hybrid, next generation work environments. As a post-doctoral fellow Christian was investigating aspects of Human Computer Interaction in virtual haptic environments. Now Christian is leading national research projects in distributed collaboration and for interactions on large high-resolution displays and in Multi-Display Environments within the CSIRO.

TITLE: Towards Optimized Quality of Experience for 3DTV and Mobile Video

SPEAKER: Lutz Goldmann


Quality of Experience in 3DTV:
The success of 3D video, as one of the emerging multimedia formats, will largely
depend on the improved quality of experience that it provides to viewers when compared
to conventional 2D video. Therefore reliable methods for 3D video quality assessment
are crucial in order to optimize 3D video systems and services. The goal of this talk is to
review recent developments in subjective and objective 3D video quality evaluation, survey
the current research activities of our group in this field and, discuss future directions and
possible collaborations.

Optimized Video Streaming for Mobile Devices:
The rapid technical evolution of portable devices and mobile networks has lead to a time
where mobile internet is extremely popular. Considering the usage trends, web video is one
of the most important services. The large variety of mobile devices and the limited bandwidth
of mobile networks, require an optimization of these video services in terms of quality and
resources. The goal of this talk is to review recent developments in mobile video streaming, survey
the current research activities of our group in this field, and discuss future directions and possible

Lutz Goldmann received the Dipl.-Ing. degree in Electrical Engeinnering from the Technische
Universität Dresden (TUD) in 2002 and the Dr.-Ing. degree in Electrical Engineering from the
Technische Universität Berlin (TUB) in 2009.
Between 2003 and 2009 he worked as a research assistant in the field of multimedia content
analysis and machine learning at the Communication Systems Lab, Technische Universität Berlin.
In 2009, he joined the Multimedia Signal Processing Group, Ecole Polytechnique Federale de
Lausanne (EPFL) as a postdoctoral researcher working on quality of experience, 3D video processing
and 2D video transcoding. During the last years he was involved in several national and international
projects, including the European Networks of Excellence 3DTV, K-Space, and VISNET and the recent

TITLE: Enabling In-Turn Processing in Spoken Dialogue Systems

SPEAKER: Timo Baumann

Current spoken dialogue systems are not yet suitable for natural, conversational dialogue for a number of technical and theoretical reasons. One major research topic in this area is incremental processing, that is, processing of user input while it is still ongoing. Incremental processing allows a system to react more quickly, to give feedback during a user's turn, or even to interrupt the user. Focussing on the input side, I will present methods that we have developed to improve incremental speech recognition and present ongoing research in predicting when a currently ongoing word is expected to end.

TITLE: Gesture-based Representations of Speech: Acquiring and Analysing Resources for Audio-visual Processing 

SPEAKER: Stephen Wilson

I’ll talk mainly about my PhD work which developed set of linguistically motivated gestures that describe visible aspects of the speech production process. These gestures form part of an innovative representational model that allows phonemic sound units to be described in terms of an underlying multitiered gestural structure, one that goes beyond the level of description afforded by the traditional unit of visual speech representation, the viseme.

Stephen Wilson is from Ireland and gained his PhD in Computer Science from University College Dublin for work on speech representations and audio-visual speech resources.At T-Labs he will be working on audio-visual asynchrony and the impact this has on perceived quality.
