Becoming a better cop by gaming?

Rieks op den Akker and Merijn Bruijnes, both from the COMMIT/project IUALL, have won the best paper award with “The Recognition of Acted Interpersonal Stance in Police Interrogations” at the 4th IEEE International Conference on Cognitive Infocommunication.

Merijn Bruijnes tells us more about the winning paper: the skill to conduct a police interview needs to be trained and the police use the model of interpersonal stance (see the picture below) to learn this skill.

We are developing a virtual suspect agent that can assist in training this skill in the form of a serious game where the police student can practice his/her interview skill on the agent.

This paper describes how suspects in a police interview express their interpersonal stance. The model of interpersonal stance consists of two axes: affiliation (are you working together or are opposed) and dominance (are you dominant or submissive).

We asked 8 actors to act out four stances dominant-positive, submissive- positive, submissive-hostile, and dominant- hostile. We asked participants to describe these clips using adjectives (see figure). 

Some clips were recognized better than others. The best clips can be used to model the behaviour of a virtual suspect agent. When the agent wants to display a stance (for example, look dominant), this work makes the agent look more human-like.
