Content of Tutorials

Mobile Multimodal Dialogue Systems (Prof. Wolfgang Wahlster)

Mobile multimodal dialogue systems allow the user and the system to adapt their choice of input and output modality according to various technical and cognitive resource limitations and the task at hand. They combine speech, gestures, haptics and facial expressions for input and/or output. Some of these systems like SMARTKOM and PEACH provide an anthropomorphic and affective interface through the personification of an interface agent. A dialogue system with symmetric multimodality must not only understand and represent the user's multimodal input, but also its own multimodal output. We present the anatomy of the SMARTKOM system, that provides full symmetric multimodality in a mixed-initiative dialogue system with an embodied conversational agent. SMARTKOM represents a new generation of multimodal dialogue systems, that deal not only with simple modality integration and synchronization, but cover the full spectrum of dialogue phenomena that are associated with symmetric multimodality (including crossmodal references, one-anaphora, and backchannelling). The application of this technology is especially motivated in non-desktop scenarios, such as smart rooms, kiosks, or mobile environments. We discuss the situated understanding of possibly imprecise, ambiguous or incomplete multimodal input and the generation of coordinated, cohesive, and coherent multimodal presentations based on advanced methods for multimodal fusion and fission. We show that plug-an-play architectures support multiple recognizers for a single modality, eg. the user's speech signal can be processed by three unimodal recognizers in parallel (speech recognition, emotional prosody, boundary prosody). The mutual disambiguation of modalities and the resolution of multimodal anaphora are based on a three-tiered discourse model, that consists of a domain, a discourse and a modality layer. We argue that intelligent multimodal interfaces are key to the consumers’ acceptance of new location-based web services for 3G UMTS smartphones and present various industrial spin-off products, e.g. the BPN system that can be used as a mobile travel companion for car drivers and pedestrians.

Tangible Interfaces (Dr. Brygg Ullmer)

This tutorial will give an introduction to the field of tangible interfaces. The first day will present an overview, theory, and context of this research area. The second day will provide a practical introduction to some of the physical and electronic tools and technologies which support and enable research in this area, including RFID tagging, rapid physical prototyping, and embedded networked computing. Tangible interfaces are a genre of human-computer interaction where spatially reconfigurable physical objects are used as representations and controls for digital information. This approach has recently drawn considerable interest, with several dozen embodying systems published over the past few years. Tangible interfaces have demonstrated special potential for contexts and domains such as collocated collaboration, simulation, and education, often situated within physical and social contexts that are poorly supported by traditional graphical interfaces. This research area has been enabled and fueled by technological advances in embedded computing, sensing, and networking; RFID tagging; and rapid physical prototyping, among others. This tutorial should give participants the theoretical and practical exposure both to understand this body of work, as well as to begin designing and realizing their own novel systems.

Building Practical Dialogue Systems (Prof. Johanna Moore & Dr. Oliver Lemon)

This course will cover a variety of techniques for building dialogue systems of different types: from simple form-filling applications to more complex task management and tutorial dialogue systems. The focus will be on choosing the right technology for a particular application to be developed, and its desired linguistic and interactive features. We will also cover a range of research issues in the field. In the first part of the course we will explain important issues in dialogue system design, such as as the representation and management of dialogue context, and the various linguistic and interactive properties which a system can exhibit (e.g. initiative, question accommodation). Then we compare the main approaches to building dialogue systems: finite state systems, form-based systems, Voice XML, agenda-based systems, task-based systems, and the "Information State Update" approach of TRINDI and DIPPER. We will present a variety of architectures, components, and resources that can be used to build working systems, many of which are freely available. We will also present a demonstration of a task-based multimodal dialogue system which uses Information State updates. The second part of the course will discuss ongoing research issues in dialogue system design, for example: Natural Language Generation in dialogue, task modelling and task switching, reconfigurable systems, context-sensitive speech recognition, and learning and adaptivity.

Instrumental interaction (Prof. Michel Beaudouin-Lafon)

This course will present the principles of graphical interaction techniques and Instrumental Interaction, a model that can describe a wide variety of interaction techniques as well as help compare them and generate new ones. I will then introduce three design principles that have proved powerful to design novel interactive systems : reification, polymorphism and reuse. I will illustrate instrumental interaction and the design principles through a real world example, the CPN2000 system developed at University of Aarhus (Denmark) Finally, I will discuss power and simplicity, two conflicting goals facing any interaction designer and how to tackle them.
