In the emergent narrative approach to Interactive Storytelling, narratives arise from the interactions between player-or computer-controlled characters in a simulated story world. This approach offers much freedom to the players, but this freedom may come at the cost of narrative structure. In this paper we study stories created by children using a(More)
As games are continuously assessing the player, this assessment can be used to adapt the complexity of a game to the proficiency of the player in real time. We performed an experiment to examine the role of dynamic adaptation. In one condition, participants played a version of our serious game for triage training that automatically adapted the complexity(More)
We present two prototypes of a serious game which is a aimed at raising police officers' awareness of social stance during street interventions by letting them interact with virtual characters. We discuss the design, implementation and evaluation of a method of feedback on the police officers' game actions. This method uses thought bubbles to show the(More)
We describe the design of a perception system for the characters in the Virtual Storyteller (VST), a character-centric story generation system. Previously, these characters were omniscient; stories involving sneaking and deception could not be generated. To remedy this, we limited the characters' visual perception using simple rules. We enabled the(More)
We demonstrate loiter-tb, a prototype of a serious game meant to improve the social awareness of police students. Central to its design is the provision of feedback through thought bubbles of virtual characters with which players interact. Our initial experiments provide weak support for our hypothesis that this form of feedback leads to gains in police(More)
In this paper we investigate the communication of children playing with an interactive digital storytelling system. What users say during their interaction with a digital storytelling system can tell us much about how they relate to the characters and how engrossed they are in the storytelling activity. We propose a communication annotation scheme that(More)
