Abstract:Simulating human behaviour in virtual persona's is an important step to create realistic virtual agents. As part of building a police interview training simulation system, a response model for suspect behaviour is created. This model is based on theory gathered in several ways. The model uses abstract factors like stance, rapport and strategies as input, updates the internal state of the system and provides a response in abstract factors such as answer type (lie/truth), answer length and friendliness. This model was validated through a user experiment in which participants acted as police officers interviewing a suspect. The experiment showed that the model provided more realistic behaviour than random output generation would and that predefined persona's were recognized 81% of the time. The response model can be used in future work to act as the decision making unit for a suspect agent in a interview training simulation.
