Interactive storytelling has been receiving a growing attention from AI and game communities and a number of computational approaches have shown promises in generating stories for games. However, there has been little research on stories evoking specific cognitive and affective responses. The goal of the work we describe here is to develop a system that(More)
Conflict is an unavoidable feature of life, but the development of conflict resolution management skills can facilitate the parties involved in resolving their conflicts in a positive manner. The goal of our research is to develop a serious game in which children may experiment with conflict resolution strategies and learn how to work towards positive(More)
We present a technology demonstrator for an adaptive serious game for teaching conflict resolution and discuss the research questions associated with the project. The prototype is a single-player 3D mini-game which simulates a resource management conflict scenario. In order to teach the player how to resolve this type of conflict, the underlying system(More)
We present an ontology-based reasoning approach for saving energy in a smart home setting where a mobile phone can serve as a generic sensor which can collect the inhabitant's contextual data. The paper details an ontology that describes the smart home domain and a prototype to test the system. Finally, we conclude with lessons learned from our work in(More)
In this paper we describe a system called ViGLS (Visualization of Game Log Summaries) that generates summaries of gameplay sessions from game logs. ViGLS automatically produces visualization of the summarized actions that are extracted based on cognitive models of summarization. ViGLS is implemented using a serviceoriented architecture, de-coupling the(More)
The advances in computing technologies enable the computer users to create and share their own stories to the community at large. However, it is still regarded as complicated and laborious to author interactive narratives, where a story adapts as the user interacts with it. In authoring interactive narratives, two main approaches—branching graphs and AI(More)
The advances in the interactive contents enable users to have a variety of experiences on diverse devices. In particular, two main approaches have been researched to construct digital interactive contents: a) conditional branch techniques and b) planning techniques. Each approach offers its own benefits; the conditional branch techniques allow the user to(More)
We experiment with mood-expressing, procedurally generated music for narrative foreshadowing in videogames, investigating the relationship between music and the player's experience of narrative events in a game. We designed and conducted a user study in which the game's music expresses true foreshadowing in some trials (e.g. foreboding music before a(More)
