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
Optimizing Player and Viewer Amusement in Suspense Video Games
Broadcast video games need to provide amusement to both players and audience. To achieve
this, one of the most consumed genres is suspense, due to the psychological effects it has on both roles.
Suspense is typically achieved in video games by controlling the amount of delivered information about
the location of the threat. However, previous research suggests that players need more frequent information
to reach similar amusement than viewers, even at the cost of jeopardizing viewers' engagement. In order
to obtain models that maximize amusement for both interactive and passive audiences, we conducted an
experiment in which a group of subjects played a suspenseful video game while another group watched it
remotely. The subjects were asked to report their perceived suspense and amusement, and the data were
used to obtain regression models for two common strategies to evoke suspense in video games: by alerting
when the threat is approaching and by random circumstantial indications about the location of the threat.
The results suggest that the optimal level is reached through randomly providing the minimal amount of
information that still allows players to counteract the threat.We reckon that these results can be applied to a
broad narrative media, beyond interactive games
Toward Intelligent Support of Authoring Machinima Media Content: Story and Visualization
The Internet and the availability of authoring tools have enabled a
greater community of media content creators, including nonexperts. However, while media authoring tools often make it technically feasible to generate, edit and share digital media artifacts, they do not guarantee that the works will be valuable or meaningful to the community at large. Therefore intelligent tools that support the authoring and creative processes are especially valuable. In this paper, we describe two intelligent support tools for the authoring and production of machinima. Machinima is a technique for producing computer-animated movies through the manipulation of computer game technologies. The first system we describe, ReQUEST, is an intelligent support tool for the authoring of plots. The second system, Cambot, produces machinima from a pre-authored script by manipulating virtual avatars and a virtual camera in a 3D graphical environment
Towards a crowdsourced solution for the authoring bottleneck in interactive narratives
Interactive Storytelling research has produced a wealth of technologies that can be
employed to create personalised narrative experiences, in which the audience takes
a participating rather than observing role. But so far this technology has not led
to the production of large scale playable interactive story experiences that realise
the ambitions of the field. One main reason for this state of affairs is the difficulty
of authoring interactive stories, a task that requires describing a huge amount of
story building blocks in a machine friendly fashion. This is not only technically
and conceptually more challenging than traditional narrative authoring but also a
scalability problem.
This thesis examines the authoring bottleneck through a case study and a literature
survey and advocates a solution based on crowdsourcing. Prior work has already
shown that combining a large number of example stories collected from crowd workers
with a system that merges these contributions into a single interactive story can be
an effective way to reduce the authorial burden. As a refinement of such an approach,
this thesis introduces the novel concept of Crowd Task Adaptation. It argues that in
order to maximise the usefulness of the collected stories, a system should dynamically
and intelligently analyse the corpus of collected stories and based on this analysis
modify the tasks handed out to crowd workers.
Two authoring systems, ENIGMA and CROSCAT, which show two radically different
approaches of using the Crowd Task Adaptation paradigm have been implemented and
are described in this thesis. While ENIGMA adapts tasks through a realtime dialog
between crowd workers and the system that is based on what has been learned from
previously collected stories, CROSCAT modifies the backstory given to crowd workers
in order to optimise the distribution of branching points in the tree structure that
combines all collected stories. Two experimental studies of crowdsourced authoring
are also presented. They lead to guidelines on how to employ crowdsourced authoring
effectively, but more importantly the results of one of the studies demonstrate the
effectiveness of the Crowd Task Adaptation approach
