Abstract. Virtual agents can provide a sense of continuity in applications that span long periods of time and incorporate diverse activities, media, and modalities. We describe the design of a virtual lactation educator -agent that promotes breastfeeding in three settings, across different time spans, using a range of media and counseling techniques. The agent provides "interpersonal continuity of care" that is important in many areas of medicine. The results of a pilot study and an ongoing clinical trial are presented.
