Abstract:
This paper is concerned with representations which enable a technical agent to recognize objects and aggregates from mechanical parts as they evolve in an ongoing construction task. The general goal is that the technical agent has a detailed understanding of the task situation such that it can execute instructions issued by a human user in a dynamically changing situation. A levelled approach for comprehensive shape representation is presented which is motivated by a cognitive model of pictorial shape representations prototypes. In particular our system is able to derive and represent spatial properties such as orientation and geometric features e.g. axes or planes that can be ascribed to the developing construct.

Natural Timing in Coverbal Gesture of an Articulated Figure

Working notes, "Communicative Agents" Workshop, Autonomous Agents '99, Seattle, WA, 1999.

Abstract:
In this paper, a virtual anthropomorphic agent is presented which is based on an articulated figure. Based on preceding work in this line, the aim of our current research is to make the agent able to perform coverbal gestures in a natural fashion. Besides the selection of the appropriate body movement to be performed as coverbal gesture, another crucial point is the correct timing of the motion with respect to the generated spoken utterance. The relationships between speech and gesture are discussed and consequences for generating coverbal gesturing and animation control of an articulated agent are drawn.

Abstract:
Dieser Beitrag stellt ein System für die sprachlich-gestische Interaktion zur Steuerung eines Systems zur Virtuellen Konstruktion vor. Eine Übersicht über verschiedene Manipulationsaufgaben in dieser Domäne dient als Grundlage, um Interaktionsbeispiele zu erläutern. Neben deiktischen Gesten des Benutzers werden mimetische Gesten, die gewünschte Veränderungen "vormachen", betrachtet. Diese werden durch sprachliche oder gestische Trigger eingeleitet und bewirken eine Anpassung in den Funktionsmodi der Auswertung, wobei zwischen diskreten und kontinuierlichen Interaktionen unterschieden wird. Um kontinuierliche Modifikationen in der virtuellen Szene umzusetzen, werden neben dem Konzept der Manipulatoren sogenannte Aktuatoren als Repräsentanten für Benutzer- modalitäten sowie Motion-Modifikatoren zur Korrektur unscharfer Sensor-Eingaben eingeführt.

Abstract:
This paper presents a technical approach for temporal symbol integration aimed to be generally applicable in unimodal and multimodal user interfaces. It draws its strength from symbolic data representation and an underlying rulebased system, and is embedded in a multi-agent system. The core method for temporal integration is motivated by findings from cognitive science research. We discuss its application for a gesture recognition task and speech-gesture integration in a Virtual Construction scenario. Finally an outlook of an empirical evaluation is given.

Abstract:
Todays multimodal systems, which allow full-body (3D) gestures and speech as input modalities, are quite restricted to easily interpretable coverbal gestures with a predefined shape and meaning. In this paper, we propose methods to abstract the concrete shape of gestures by using high-level features and to integrate them with coexpressive words using their phonological attributes. The application of this approach is discussed for a class of gestures useful in virtual design. We sketch our technical environment and first implementation approaches to build a prototype system.

Abstract:
Led by the fundamental role that rhythms apparently play in speech and gestural communication among humans, this study was undertaken to substantiate a biologically motivated model for synchronizing speech and gesture input in human computer interaction. Our approach presents a novel method which conceptualizes a multimodal user interface on the basis of timed agent systems. We use multiple agents for the purpose of polling presemantic information from different sensory channels (speech and hand gestures) and integrating them to multimodal data structures that can be processed by an application system which is again based on agent systems. This article motivates and presents technical work which exploits rhythmic patterns in the development of biologically and cognitively motivated mediator systems between humans and machines.
