Adding nonverbal behaviors. Nonverbal behaviors were added using the Cornerstone Immerse (formerly Talespin CoPilot Designer) avatar animation features. The interface enables poses and gestures to be combined and aligned to the conversation. The vertical yellow bar indicates the current frame in which the avatar is leaning forward (“Interested” pose) while nodding (“Head Nodding Forward” gesture) and smiling (“Face Smile” gesture). (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
