At the moment, most research in HRI is done in a 1-to-1 situation. However real relationships are mostly n-to-m relationships. To test what influence this relationships might have on human language and human behavior we created Morphessor. Morephessor is a board game based research platform to study multi agent verbal Human-Robot Interactions. The platform is specifically made to be flexible and scalable. It is designed to run in the browser so it can also be used outside the lab. The robot interface can either be a real robot or a virtual robot.
