Book Description
Embodied Conversational Agents (ECAs) are a new type of computer interface which have human-like bodies and conversational skills. Users interacting with agents will be more engaged and participative if the agents exhibit behaviors which look coherent across different situations and emotional states. In the present work, we aim at increasing agents' believability by looking at two main aspects of the problem: - an agent must be able to show its emotional state and communicative intentions not only through specific facial expressions, gestures, etc., but also by varying the quality of its movements (e.g., their speed, amplitude, etc.) and the choice of the modalities that are used to communicate; - the agent must maintain a distinctive behavior, that is, its global behavior tendency has to remain apparent during any communication. We have developed a model to solve the two above issues. We have evaluated the realism and believability of the resulting agent's behaviors through perceptual tests and application scenario. The resulting system is highly extensible and configurable. It can also be used as a research tool to study human communication.

Book Description
During a conversation, listeners do not assimilate passively all of the speaker's words; they actively participate in the interaction providing information about how they feel and what they think of the speaker's speech. The speaker relies on signals emitted by the listener to know if he is listening or not, understanding or not, agreeing or not, etc. This informs the speaker on the success or failure of the communication and helps him to decide how to carry on with the interaction. In this thesis, to refer to signals provided by listeners, we adopt the term backchannel proposed by Yngve. We define backchannels as acoustic and non-verbal signals provided during the speaker's turn to exchange information about the communicative functions: contact, perception, understanding, and attitude. Backchannels are emitted in a non-intrusive way: that is, without interrupting the speaker's speech. Two fundamental characteristics of backchannels are: (i) they can be emitted at different level of intentionality; (ii) they can be reactive (deriving from a first process of perception of the speaker's speech) or response (deriving from a more aware evaluation). A particular form of backchannel is the mimicry of the speaker's behavior. By mimicry, we mean the behavior displayed by an individual who does what another person does. This type of behavior has been proven to play quite an important role during conversations. Due to the importance of the listener's behavior, in this thesis we propose to implement a model that generates this type of behavior for an Embodied Conversational Agent while interacting with a user. We aim to improve the human-machine interaction.

Book Description
Musical robotics is a multi- and trans-disciplinary research area involving a wide range of different domains that contribute to its development, including: computer science, multimodal interfaces and processing, artificial intelligence, electronics, robotics, mechatronics and more. A musical robot requires many different complex systems to work together; integrating musical representation, techniques, expressions, detailed analysis and controls, for both playing and listening. The development of interactive multimodal systems provides advancements which enable enhanced human-machine interaction and novel possibilities for embodied robotic platforms. This volume is focused on this highly exciting interdisciplinary field. This book consists of 14 chapters highlighting different aspects of musical activities and interactions, discussing cutting edge research related to interactive multimodal systems and their integration with robots to further enhance musical understanding, interpretation, performance, education and enjoyment. It is dichotomized into two sections: Section I focuses on understanding elements of musical performance and expression while Section II concentrates on musical robots and automated instruments. Musical Robots and Interactive Multimodal Systems provides an introduction and foundation for researchers, students and practitioners to key achievements and current research trends on interactive multimodal systems and musical robotics.

Book Description
Embodied conversational agents (ECA) and speech-based human-machine interfaces can together represent more advanced and more natural human-machine interaction. Fusion of both topics is a challenging agenda in research and production spheres. The important goal of human-machine interfaces is to provide content or functionality in the form of a dialo

Book Description
Communication is not just about the transfer of verbal information. Gestures, facial expressions, intonation and body language are all major sources of information during conversation. This book presents a new perspective on communication, one that will help us to better understand humans, and also to build machines that can communicate.

Book Description
Computer graphics is now used in various fields; for industrial, educational, medical and entertainment purposes. The aim of computer graphics is to visualize real objects and imaginary or other abstract items. In order to visualize various things, many technologies are necessary and they are mainly divided into two types in computer graphics: modeling and rendering technologies. This book covers the most advanced technologies for both types. It also includes some visualization techniques and applications for motion blur, virtual agents and historical textiles. This book provides useful insights for researchers in computer graphics.

Book Description
Recent years have seen the rise of a remarkable partnership between the social and computational sciences on the phenomena of emotions. This book reports on the state-of-the-art in both social science theory and computational methods, and illustrates how these two fields, together, can both facilitate practical computer/robotic applications and illuminate human social processes.
