"IPSViz: After Action Review for Human-Virtual Human Experiences"

Abstract: In this talk, I propose pairing after-action review with human-virtual human (H-VH) experiences. H-VH experiences are seeing increased use for interpersonal skills training in a variety of application domains, including military leadership, cultural competency, law enforcement, and medicine. Adding after-action review to H-VH experiences improves training by enabling end-users to review, evaluate, and get feedback on their interpersonal skills.

The interpersonal scenario visualizer (IPSViz), a visualization system that supports after-action review of H-VH experiences, is presented. IPSViz supports after-action review by generating visualizations that highlight communication between a human and a virtual human. IPSViz builds upon my previous work on a training system that allows medical students to practice patient interviews by interacting with virtual human patients. Immediately after interviewing a virtual human patient, medical students use IPSViz to review their interview and gain insight into their interpersonal communication skills. The results of a user study (N=27) indicate that after-action review with IPSViz: 1) changes end-user perceptions of their interactions with virtual humans and 2) has the potential to improve end-user interactions with real humans.
