Player agency in interactive narrative: audience, actor & author
The question motivating this review paper is, how can
computer-based interactive narrative be used as a constructivist learn-
ing activity? The paper proposes that player agency can be used to
link interactive narrative to learner agency in constructivist theory,
and to classify approaches to interactive narrative. The traditional
question driving research in interactive narrative is, ‘how can an in-
teractive narrative deal with a high degree of player agency, while
maintaining a coherent and well-formed narrative?’ This question
derives from an Aristotelian approach to interactive narrative that,
as the question shows, is inherently antagonistic to player agency.
Within this approach, player agency must be restricted and manip-
ulated to maintain the narrative. Two alternative approaches based
on Brecht’s Epic Theatre and Boal’s Theatre of the Oppressed are
reviewed. If a Boalian approach to interactive narrative is taken the
conflict between narrative and player agency dissolves. The question
that emerges from this approach is quite different from the traditional
question above, and presents a more useful approach to applying in-
teractive narrative as a constructivist learning activity
Facilitating open plot structures in story driven video games using situation generation
Story driven video games are rising in popularity, along with the players desire to make meaningful choice within the plot and therefore become more involved and immersed within the experience. This paper investigates the problems which arise from implementing interactive narrative within video games and potential techniques to solve those problems. The main focus of the study was the situation generation technique, used to maintain the continuity within open, emergent plot structures, using behaviour trees as a means to implement and traverse plot sequences. The ISGEngine was developed during the course of this study in order to implement and evaluate the situation generation technique
Designing online role plays with a focus on story development to support engagement and critical learning for higher education students
Online role plays, as they are designed for use in higher education in Australia and internationally, are active and authentic learning activities (Wills, Leigh & Ip, 2011). In online role plays, students take a character role in developing a story that serves as a metaphor for real-life experience in order to develop a potentially wide range of subject-related and generic learning outcomes. The characteristics of these stories are rarely considered as factors in the design―and success―of these activities. The unspoken cultural assumptions, norms and rules in the stories that impact on the meanings students make from their experiences are also rarely scrutinised in the online role play literature. This paper presents findings from a case study of an asynchronous text-based online role play involving politics and journalism students from three Australian universities. The findings highlight the centrality of students’ collaborative story-building activity to their engagement and learning, including their development of critical perspectives. The study underlines the importance of certain aspects of the role play\u27s design to support students\u27 story-building activity
Ontological Approaches to Modelling Narrative
We outline a simple taxonomy of approaches to modelling narrative, explain how these might be realised ontologically, and describe our continuing work to apply these techniques to the problem of Memories for Life

The Cosmos Project: a journey to the stars
There seems to be some agreement that ‘science for all’ does not necessarily mean ‘one size fits all’ (Lynch, 2001). Teaching scientific disciplines in schools has been traditionally concerned with delivering science as a product with a main focus on its conceptual structure. In our research we propose to concentrate on science as a process, putting it in the societal context. We introduce the Cosmos project that aims to explore the use of narrative and performative languages, as well as new media technologies in relation to delivering complex scientific topics to pre-school children aged three to six. We created a theatrical piece and developed a set of new interactive preschool activities that enabled young learners to participate and contribute to their learning through physical engagement enhanced by modern technologies. This paper presents a critical discussion about the recent tendencies in teaching science to young learners; the rationale for the Cosmos project and its main research objectives. It will conclude with evaluation of the pre- and postperformance educational activities
Agents for educational games and simulations
This book consists mainly of revised papers that were presented at the Agents for Educational Games and Simulation (AEGS) workshop held on May 2, 2011, as part of the Autonomous Agents and MultiAgent Systems (AAMAS) conference in Taipei, Taiwan. The 12 full papers presented were carefully reviewed and selected from various submissions. The papers are organized topical sections on middleware applications, dialogues and learning, adaption and convergence, and agent applications
SAGA: A DSL for Story Management
Video game development is currently a very labour-intensive endeavour.
Furthermore it involves multi-disciplinary teams of artistic content creators
and programmers, whose typical working patterns are not easily meshed. SAGA is
our first effort at augmenting the productivity of such teams.
Already convinced of the benefits of DSLs, we set out to analyze the domains
present in games in order to find out which would be most amenable to the DSL
approach. Based on previous work, we thus sought those sub-parts that already
had a partially established vocabulary and at the same time could be well
modeled using classical computer science structures. We settled on the 'story'
aspect of video games as the best candidate domain, which can be modeled using
state transition systems.
As we are working with a specific company as the ultimate customer for this
work, an additional requirement was that our DSL should produce code that can
be used within a pre-existing framework. We developed a full system (SAGA)
comprised of a parser for a human-friendly language for 'story events', an
internal representation of design patterns for implementing object-oriented
state-transitions systems, an instantiator for these patterns for a specific
'story', and three renderers (for C++, C# and Java) for the instantiated
abstract code.Comment: In Proceedings DSL 2011, arXiv:1109.032
Improvising Linguistic Style: Social and Affective Bases for Agent Personality
This paper introduces Linguistic Style Improvisation, a theory and set of
algorithms for improvisation of spoken utterances by artificial agents, with
applications to interactive story and dialogue systems. We argue that
linguistic style is a key aspect of character, and show how speech act
representations common in AI can provide abstract representations from which
computer characters can improvise. We show that the mechanisms proposed
introduce the possibility of socially oriented agents, meet the requirements
that lifelike characters be believable, and satisfy particular criteria for
improvisation proposed by Hayes-Roth.Comment: 10 pages, uses aaai.sty, lingmacros.sty, psfig.st
Video summarisation: A conceptual framework and survey of the state of the art
This is the post-print (final draft post-refereeing) version of the article. Copyright @ 2007 Elsevier Inc.Video summaries provide condensed and succinct representations of the content of a video stream through a combination of still images, video segments, graphical representations and textual descriptors. This paper presents a conceptual framework for video summarisation derived from the research literature and used as a means for surveying the research literature. The framework distinguishes between video summarisation techniques (the methods used to process content from a source video stream to achieve a summarisation of that stream) and video summaries (outputs of video summarisation techniques). Video summarisation techniques are considered within three broad categories: internal (analyse information sourced directly from the video stream), external (analyse information not sourced directly from the video stream) and hybrid (analyse a combination of internal and external information). Video summaries are considered as a function of the type of content they are derived from (object, event, perception or feature based) and the functionality offered to the user for their consumption (interactive or static, personalised or generic). It is argued that video summarisation would benefit from greater incorporation of external information, particularly user based information that is unobtrusively sourced, in order to overcome longstanding challenges such as the semantic gap and providing video summaries that have greater relevance to individual users
