The purpose of this project is to develop technology for virtual humans to act as question-answering characters as part of interviewer training. Trainee interviewers can practice by interviewing virtual characters. The focus of the project is on tactical questioning, but the technology has been used successfully for a variety of interview tasks, including reporter-source, criminal investigator-prisoner, doctor-patient, and also used for training deception detection. The starting point was the Sgt Blackwell Character. We have since created several characters and a couple of generations of the architecture for tactical questioning characters.
