In recent years increasing attention has been given to making interactions with Intelligent Virtual Agents (IVAs) more human-like, for example by incorporating social competencies such as expressive speech and body gestures, incorporating backchannels and more realistic turn-taking into dialogue systems. Although such competencies have been seen as important in improving the human-like nature of IVA interaction, little is known about how these aspects contribute to the level of engagement between human and virtual agent or how such a concept can be evaluated in these contexts. This workshop explores the role of these social competencies in engaging interlocutors in successful social communication and how to evaluate user engagement in such interactions.
Engagement refers to the quality of the user experience that emphasizes the positive aspects of the interaction. Numerous methods have been proposed to measure engagement, but further work is needed to validate and relate these measures and so provide a firm basis for assessing the quality of the user experience in a virtual agent context. By exploring the potential of subjective (questionnaire, user perception) and objective (behavioral and multimodal feature extraction for engagement classification) engagement measures, the ultimate aim of this workshop is to contribute to the discussion on how user engagement can be studied, measured, and explained, to facilitate the development of user interfaces able to engage users in social communication.

Particular topics of interest include but not limited to:

  • Analysis of social aspects of speech communication relevant for engagement.
  • Development of technology for Social Competent Intelligent Virtual Agents.
  • Evaluation of applications of IVAs which expect to engage in the interaction and provide a more immersive communication similar to that found in communication between humans, such as companion agents for health care, animated characters in video games, etc.
  • Experimental methodologies that are useful for evaluation of engagement.
  • Inference of engagement from semantic analysis of the human speech, biometric data captured using sensors and other multimodal data such as gestures.
  • Social signal processing and computer vision techniques to capture and interpret social behaviour such as posture, gesture and facial signals.
  • Machine learning methods for classification of engagement.
