Emergent narrative (EN) is a narrative concept in virtual reality that relies on emergence for a flexible shaping of stories as opposed to fixed pre-determined plots. This has consequences for the creative role of the author in an EN system. In this paper, we aim to clarify the actual function of the author by investigating what is exactly mediated in ENs and how this can be filled in by an author at design time.

We describe CMION, an open source architecture for coordinating the various sensors and effectors of an artificial intelligent agent with its mind, i.e. the high level decision making processes. The architecture was designed to work for virtual graphical agents, including those on mobile devices, as well as robots. Its built-in migration feature allows a character to move between these differing embodiments, inhabiting them in turn. We emphasize the importance of modularity for an architecture supporting migration and highlight design decisions promoting modularity in CMION. An applied example of the architectures use in a migration situation is given.

Role-play can be a powerful educational tool, especially when dealing with social or ethical issues. However, while other types of educational activity have been routinely technology-enhanced for some time, the specific problem of supporting educational role-play with technology has only begun to be tackled recently. Within the eCIRCUS project we have designed a framework for technology-enhanced role-play with the aim of educating adolescents about intercultural empathy. This work was influenced by related fields such as intelligent virtual agents, interactive narrative and pervasive games. In this paper, we will describe the different components of our role-play technology by means of a prototype implementation of this technology, the ORIENT showcase. Furthermore we will present results of our evaluation of ORIENT.

This paper investigates how graphically displayed intelligent virtual actors, mobile devices and innovative interaction modalities can support and enhance educational role-play as well as deepen the sense of engagement and presence in participants to produce more successful learning. The discussion will be presented using a showcase from the eCIRCUS project, ORIENT, an application combining virtual and real life role-play for social and emotional learning.

This paper investigates user perceptions of continuous identity as agents migrate between different embodiments. It reports an experiment seeking to establish whether migrating or not migrating the interaction memory of the agent would affect the users perception of consistent agent identity over different embodiments. The experiment involved a treasure hunt in which a virtual agent migrated from a screen to a mobile phone in order to accompany a user while they searched for clues. A total of 45 subjects took part in three different conditions with 15 subjects in each. The outcome showed that the presence of memory affected the competence users ascribed to the virtual agent. However it had no significant effect on a strong perception of consistent identity across multiple embodiments.

ENIGMA is an experimental platform for collaborative authoring of the behaviour of autonomous virtual characters in interactive narrative applications. The main objective of this system is to overcome the bottleneck of knowledge acquisition that exists in generative storytelling systems through a combination of crowd-sourcing and machine learning. While the authoring front-end of the application is used to create short example stories set in a specific story domain, the server side of the application collects many of those stories and derives behaviour models for autonomous virtual characters such as formal planning operator descriptions from them. A mixed initiative mode increases coherence by feeding already learnt character behaviour back into the client.
