title: Movie magic in the clinic: computer-generated characters for automated health counseling.
abstract: In this presentation, I demonstrate how many of the technologies used in movie special effects and games have been successfully used in health education and behavior change interventions. Computer-animated health counselors simulate human face-to-face dialogue as a computer interface medium, including not only verbal behavior but nonverbal conversational behavior such as hand gesture, body posture shifts, and facial display of emotion. This technology has now been successfully used in a wide range of health interventions for education and counseling of patients and consumers, including applications in physical activity promotion, medication adherence, and hospital discharge. These automated counselors have been deployed on home computers, hospital-based touch screen kiosks, and mobile devices with integrated health behavior sensing capability. Development of these agents is an interdisciplinary endeavor spanning the fields of character modeling and animation, computational linguistics, artificial intelligence, health communication and behavioral medicine. I will give demonstrations of several fielded systems, describe the technologies and methodologies underlying their development, and present results from five randomized controlled trials that have been completed or are in progress.
