    Embodied Conversational Agents

    Justine Cassell, Joseph Sullivan, Scott Prevost, and Elizabeth F. Churchill

    This book describes research in all aspects of the design, implementation, and evaluation of embodied conversational agents as well as details of specific working systems.

    Embodied conversational agents are computer-generated cartoonlike characters that demonstrate many of the same properties as humans in face-to-face conversation, including the ability to produce and respond to verbal and nonverbal communication. They constitute a type of (a) multimodal interface where the modalities are those natural to human conversation: speech, facial displays, hand gestures, and body stance; (b) software agent, insofar as they represent the computer in an interaction with a human or represent their human users in a computational environment (as avatars, for example); and (c) dialogue system where both verbal and nonverbal devices advance and regulate the dialogue between the user and the computer. With an embodied conversational agent, the visual dimension of interacting with an animated character on a screen plays an intrinsic role. Not just pretty pictures, the graphics display visual features of conversation in the same way that the face and hands do in face-to-face conversation among humans. This book describes research in all aspects of the design, implementation, and evaluation of embodied conversational agents as well as details of specific working systems. Many of the chapters are written by multidisciplinary teams of psychologists, linguists, computer scientists, artists, and researchers in interface design. The authors include Elisabeth Andre, Norm Badler, Gene Ball, Justine Cassell, Elizabeth Churchill, James Lester, Dominic Massaro, Cliff Nass, Sharon Oviatt, Isabella Poggi, Jeff Rickel, and Greg Sanders.

  • Critical Theory and Interaction Design

    Critical Theory and Interaction Design

    Jeffrey Bardzell, Shaowen Bardzell, and Mark Blythe

    Classic texts by thinkers from Althusser to Žižek alongside essays by leaders in interaction design and HCI show the relevance of critical theory to interaction design.

    Why should interaction designers read critical theory? Critical theory is proving unexpectedly relevant to media and technology studies. The editors of this volume argue that reading critical theory—understood in the broadest sense, including but not limited to the Frankfurt School—can help designers do what they want to do; can teach wisdom itself; can provoke; and can introduce new ways of seeing. They illustrate their argument by presenting classic texts by thinkers in critical theory from Althusser to Žižek alongside essays in which leaders in interaction design and HCI describe the influence of the text on their work. For example, one contributor considers the relevance Umberto Eco's “Openness, Information, Communication” to digital content; another reads Walter Benjamin's “The Author as Producer” in terms of interface designers; and another reflects on the implications of Judith Butler's Gender Trouble for interaction design. The editors offer a substantive introduction that traces the various strands of critical theory.

    Taken together, the essays show how critical theory and interaction design can inform each other, and how interaction design, drawing on critical theory, might contribute to our deepest needs for connection, competency, self-esteem, and wellbeing.
