Playing The Role: Towards An Action Selection Architecture For Believable Behaviour In Non Player Characters and Interactive Agents

Non Player Characters(NPC) in many types of video games must make believable choices in order to create player immersion and enjoyment. This thesis proposes, implements and tests a novel NPC architecture making use of Role Theory, Appraisal Theory and Utility-Based decision making

Building Artificially Intelligent Learning Games

The idea of digital game-based learning (DGBL) is gaining acceptance among researchers, game designers, educators, parents, and students alike. Building new educational games that meet educational goals without sacrificing what makes games engaging remains largely unrealized, however. If we are to build the next generation of learning games, we must recognize that while digital games might be new, the theory and technologies we need to create DGBL has been evolving in multiple disciplines for the last 30 years. This chapter will describe an approach, based on theories and technologies in education, instructional design, artificial intelligence, and cognitive psychology, that will help us build intelligent learning games (ILGs)

An Architecture for Believable Socially Aware Agents

The main focus of this thesis is to solve the believability problem in video game agents by integrating necessary psychological and sociological foundations by means of role based architecture. Our design agent also has the capability to reason and predict the decisions of other actors by using its own mental model. The agent has a separate mental model for every actor

Directed Emergent Drama

A fully interactive drama, where the player interacts with intelligent Non- Player Characters (NPCs), can revolutionise entertainment, gaming, education, and therapy. Creating such a genuinely interactive drama that is entertaining and gives players a sense of coherency as active participants in the unfolding drama has seen a substantial research effort. Authors have the power to shape dramatised stories for theatre or television at will. Conversely, the authors' ability to shape interactive drama is limited because the drama emerges from players' and NPCs actions during game-play, which significantly limits authoring control. A coherent drama has a recognisable dramatic structure. One philosophy is to use planning algorithms and narrative structures to reduce required authoring. However, planning algorithms are intractable for the large state-spaces intrinsic to interactive dramas, and they have not reduced the authoring problem sufficiently. A more straightforward and computationally feasible method is emergent interactive drama from players' and NPCs' actions. The main difficulty with this approach is maintaining a drama structure and theme, such as a mystery theme or a training scenario, that the player experiences while interacting with the game world. Therefore, it is necessary to impose some form of structure to guide or direct the unfolding drama. The solution introduced in this thesis is to distribute the computation among autonomous actors that are guided by goals and drama structures which a centralised autonomous director agent distributes among the actors, which comprises the following four main elements: a) autonomous rational actor agents that know they are acting and can negotiate dialogues between them to remain realistic while simultaneously progressing the drama, without the player knowing, b) Bayesian network to model the actors reasoning, including beliefs about other actors' mental states c) an autonomous director agent uses "schemas", conceptual structures based on motifs, to guide the actors

Designing an engaging learning universe for situated interactions in virtual environments

A thesis submitted to the University of Bedfordshire, in partial fulfilment of the requirements for the degree of Doctor of Philosophy (PhD)Studies related to the Virtual Learning approach are conducted almost exclusively in Distance Learning contexts, and focus on the development of frameworks or taxonomies that classify the different ways of teaching and learning. Researchers may be dealing with the topic of interactivity (avatars and immersion are key components), yet they do so they mainly focusing on the interactions that take place within the virtual world. It is the virtual world that consists the primary medium for communication and interplay. However, the lines are hard to be drawn when it comes to examining and taxonomising the impact of interactions on motivation and engagement as a synergy of learners’ concurrent presence. This study covers this gap and sheds light on this lack—or, at least, inadequacy—of literature and research on the interactions that take place both in the physical and the virtual environment at the same time. In addition, it explores the impact of the instructional design decisions on increasing the learners’ incentives for interplay when trying to make sense of the virtual world, thus leading them to attain higher levels of engagement. To evaluate the potential of interactions holistically and not just unilaterally, a series of experiments were conducted in the context of different Hybrid Virtual Learning units, with the participation of Computer Science & Technology students. One of the goals was to examine the learners’ thoughts and preconceptions regarding the use of virtual worlds as an educational tool. Then, during the practical sessions, the focus was placed on monitoring students’ actions and interactions in both the physical and the virtual environment. Consequently, students were asked as a feedback to report their overall opinion on these actions and interactions undertaken. The study draws a new research direction, beyond the idea of immersion and the development of subject-specific educational interventions. The conclusions provide suggestions and guidelines to educators and instructional designers who wish to offer interactive and engaging learning activities to their students, as well as a taxonomy of the different types of interactions that take place in Hybrid Virtual Learning contexts

Cultural literacy acquisition through video game environments of a digitally born generation

[ES] Los videojuegos modernos son complejos, diversos, inmersivos y muy extendidos, y su influencia en la sociedad y en las personas es muy profunda. Al principio, los videojuegos y sus impactos fueron demonizados, pero con el tiempo los estudios empezaron a evaluar sus efectos positivos en las competencias y habilidades relacionadas con las destrezas del siglo XXI, entre las que se encuentra la alfabetización cultural. Esta tesis sigue esta tendencia y examina el modo en que los juegos de entretenimiento comerciales, los juegos serios, los juegos educativos y las simulaciones pueden ayudar a los jugadores en su aprendizaje y en la adquisición de destrezas que mejoran su alfabetización cultural. Un análisis de las tendencias comunes en las destrezas y competencias necesarias para tener éxito en el siglo XXI (estudiadas por la UNESCO, el British Council, IBM, Google, LinkedIn y el Foro Económico Mundial) reveló que para vivir en un mundo VUCA (volátil, incierto, complejo y ambiguo) hace falta un modelo nuevo y actualizado de la alfabetización cultural. Esta tesis propone tal modelo. Se hizo una revisión de la literatura reciente sobre el impacto y los resultados de los videojuegos. Dicha revisión mostró que los videojuegos pueden reforzar o debilitar los estereotipos, que ayudan a adquirir conocimientos culturales y a desarrollar la alfabetización intercultural, la alfabetización sociocultural, la conciencia cultural, la autoconciencia y el entendimiento cultural de diferentes espacios geopolíticos, y que hasta cierto punto facilitan el desarrollo de las habilidades interculturales. El corazón de la tesis es una investigación sobre la efectividad de los videojuegos en el abordaje de problemas sociales difíciles como son los movimientos migratorios y la crisis de refugiados. Se realizaron dos estudios, uno cuantitativo y otro cualitativo, que obtuvieron resultados alentadores para los creadores de videojuegos de empatía. Muchos participantes informaron que sintieron más empatía y menos rechazo hacia los migrantes y refugiados, así como una mayor motivación para ayudar de forma activa a gente necesitada. Se hizo, además, una encuesta amplia que dio a conocer los géneros de entretenimiento AAA, los personajes, los elementos de juego y las características que los nativos digitales encuentran atractivos, así como los que echan en falta y que les gustaría ver en el futuro. Los hallazgos también confirmaron que los juegos no son solamente una fuente de diversión, sino también de mucho aprendizaje. El inglés, las bases de la informática, el pensamiento estratégico, la geografía y la historia, el trabajo en equipo, conocimientos culturales, el cambio de perspectiva y la creatividad... todo esto se aprende y refuerza con los videojuegos. Las evidencias presentadas en esta tesis sugieren que hay una demanda para herramientas que faciliten la educación intercultural. El punto culminante de esta tesis es el diseño de Chuzme, un juego educativo digital que pretende elevar la autoconciencia (cultural) y el reconocimiento del sesgo cultural con el fin de generar actitudes positivas hacia los migrantes, refugiados y expatriados. En resumen, esta tesis apoya la idea de que los videojuegos facilitan la adquisición de la alfabetización cultural y aporta pruebas de que los videojuegos proporcionan beneficios culturales, sociales y comunicativos que espere animen a los profesores a integrar activamente los videojuegos en su práctica docente.

Al principi, els videojocs i els seus impactes van ser demonitzats però amb el temps els estudis van començar a avaluar els seus efectes positius en les competències i habilitats relacionades amb les destreses del segle XXI, entre les quals es troba l'alfabetització cultural. Aquesta tesi segueix aquesta tendència i examina la manera en què els jocs d'entreteniment comercials, els jocs seriosos, els jocs educatius i les simulacions poden ajudar els jugadors en el seu aprenentatge i en l'adquisició de destreses que milloren la seva alfabetització cultural. Una anàlisi de les tendències comunes en les destreses i competències necessàries per tenir èxit en el segle XXI (estudiades per la UNESCO, el British Council, IBM, Google, LinkedIn i el Fòrum Econòmic Mundial) va revelar que per viure en un món VUCA (volàtil , incert, complex i ambigu) cal un model nou i actualitzat de l'alfabetització cultural. Aquesta tesi proposa aquest model. Es va fer una revisió de la literatura recent sobre l'impacte i els resultats dels videojocs. La dita revisió va mostrar que els videojocs poden reforçar o debilitar els estereotips, que ajuden a adquirir coneixements culturals i a desenvolupar l'alfabetització intercultural, l'alfabetització sociocultural, la consciència cultural, l'autoconsciència i l'enteniment cultural de diferents espais geopolítics, i que fins a cert punt faciliten el desenvolupament de les habilitats interculturals. El cor de la tesi és una investigació sobre l'efectivitat dels videojocs en l'abordatge de problemes socials difícils com són els moviments migratoris i la crisi de refugiats. Es van realitzar dos estudis, un quantitatiu i un altre qualitatiu, que van obtenir resultats encoratjadors per als creadors de videojocs d'empatia. Molts participants van informar que van sentir més empatia i menys rebuig cap als immigrants i refugiats, així com una major motivació per ajudar de forma activa a gent necessitada. Es va fer, a més, una enquesta àmplia que va donar a conèixer els gèneres d'entreteniment AAA, els personatges, els elements de joc i les característiques que els nadius digitals troben atractius així com els que troben a faltar i que els agradaria veure en el futur. Les troballes també van confirmar que els jocs no són només una font de diversió, sinó també de molt aprenentatge. L'anglès, les bases de la informàtica, el pensament estratègic, la geografia i la història, el treball en equip, coneixements culturals, el canvi de perspectiva i la creativitat ... tot això s'aprèn i reforça amb els videojocs. Les evidències presentades en aquesta tesi suggereixen que hi ha una demanda per a eines que facilitin l'educació intercultural. El punt culminant d'aquesta tesi és el disseny de Chuzme, un joc educatiu digital que pretén elevar l'autoconsciència (cultural) i el reconeixement del biaix cultural amb la finalitat de generar actituds positives cap als migrants, refugiats i expatriats. En resum, aquesta tesi dóna suport a la idea que els videojocs faciliten l'adquisició de l'alfabetització cultural i aporta proves que els videojocs proporcionen beneficis culturals, socials i comunicatius que esperi animin els professors a integrar activament els videojocs en la seva pràctica docent.

Video games and their impacts were initially demonised, but over time research started assessing the positive effects of games on competencies and abilities connected to twenty-first-century skills that include cultural literacy. In line with this trend, this thesis examines how entertaining commercial titles, serious games, educational games and simulations can support players in learning and in acquiring skills that enhance cultural literacy. An analysis of the common trends for the skills and competencies needed for success in the twenty-first century ¿studied by UNESCO, the British Council, IBM, Google, LinkedIn, and the World Economic Forum, among other,¿ revealed that living in a VUCA (volatility, uncertainty, complexity and ambiguity) world requires a new, updated model of cultural literacy. This thesis proposes such a model. A review was made of the recent literature on the impact and outcomes of video games, showing that video games can reinforce or weaken stereotypes; help to acquire cultural knowledge and develop intercultural literacy, socio-cultural literacy, cultural awareness, self-awareness, and the cultural understanding of different geopolitical spaces; and to some extent also facilitate the development of intercultural skills. The heart of the thesis is an investigation into the effectiveness of video games for tackling difficult social issues such as migratory movements and the refugee crisis. Two studies were conducted one quantitative and the other qualitative that obtained heartening results for producers of empathy video games. Many participants reported feeling more empathy and less rejection towards migrants and refugees, as well as being more motivated to actively help people in need. Additionally, a broad survey revealed the AAA entertainment game genres, characters, and in-game elements and features that digital natives find attractive and those they miss and would like in the future. The findings also confirmed that games produce not only fun but also a great deal of learning. The English language, the basics of informatics, strategic thinking, geography and history, teamwork, cultural knowledge, perspective change, and creativity are all learnt and reinforced during video game play. The evidence presented in this thesis suggests there is a demand for tools facilitating intercultural education. The high point of the thesis is the design of Chuzme, an educational digital game that focuses on raising cultural self-awareness and the acknowledgement of cultural bias in order to generate positive attitudes towards migrants, refugees and expatriates. In summary, this thesis supports the idea that video games facilitate the acquisition of cultural literacy and provides evidence on the cultural, social and communication bene¿ts of gaming that hopefully encourages scholars to actively integrate video games in their teaching practice.

DISE : a game technology-based digital interactive storytelling framework

This thesis details the design and implementation of an Interactive Storytelling Framework. Using software engineering methodology and framework development methods, we aim to design a full Interactive Storytelling system involving a story manager, a character engine, an action engine, a planner, a 3D game engine and a set of editors for story data, world environment modelling and real-time character animation. The framework is described in detail and specified to meet the requirement of bringing a more dynamic real-time interactive story experience to the medium of computer games. Its core concepts borrow from work done in the fields of narrative theory, software engineering, computer games technology, HCI, 3D character animation and artificial intelligence. The contributions of our research and the novelties lie in the data design of the story which allows a modular approach to building reusable resources such as actions, objects, animated characters and whole story 'levels'; a switchable story planner and re-planning system implementation, allowing many planners, heuristics and schedulers that are compatible with PDDL (the "Planning Domain Definition Language") to be easily integrated with minor changes to the main classes; a 3D game engine and framework for web launched or in browser deployment of the finished product; and a user friendly story and world/environment editor; so story authors do not need advanced knowledge of coding PDDL syntax, games programming or 3D modelling to design and author a basic story. As far as we know our Interactive Storytelling Framework is the only one to include a full 3D cross-platform game engine, procedural and manual modelling tools, a story -editor and customisable planner in one complete integrated solution. The finished interactive storytelling applications are presented as computer games designed to be a real-time 3D first person experience, with the player as a main story character in a world where every context filtered action displayed is executable and the player's choices make a difference to the outcome of the story, whilst still allowing the authors high level constraints to progress the narrative along their desired path(s)

Adding simple simulations to video games to improve realism

In this paper a method of enhancing the realism of certain computer game types, particularly First Person Shooter games, is explored by attempting to include intelligent neutral background characters to the game environment. This method also requires that the inclusion of these background characters will not adversely affect the performance of a game by drastically increasing the computational complexity of the game. A simulation was created to show how this can be done using a group of intelligent agents based in a simulated world, and a simplified system of norms designed to influence the agents’ behavior. The agents are designed to interact with each other and other objects in their virtual world, in a fashion that could be considered human-like. To show the validity of this method, the simulation was designed to be minimally resource intensive. Furthermore, extensive tests were performed using a variety of initial starting values for various aspects of the simulation, to show that the simulation, and thus the method, can sustain itself long enough to provide an improvement to a gaming environment. The results of the tests are discussed at length, as well as theories as to how this method could be used successfully in computer gaming

Second-Person Surveillance: Politics of User Implication in Digital Documentaries

This dissertation analyzes digital documentaries that utilize second-person address and roleplay to make users feel implicated in contemporary refugee crises, mass incarceration in the U.S., and state and corporate surveillances. Digital documentaries are seemingly more interactive and participatory than linear film and video documentary as they are comprised of a variety of auditory, visual, and written media, utilize networked technologies, and turn the documentary audience into a documentary user. I draw on scholarship from documentary, game, new media, and surveillance studies to analyze how second-person address in digital documentaries is configured through user positioning and direct address within the works themselves, in how organizations and creators frame their productions, and in how users and players respond in reviews, discussion forums, and Let’s Plays. I build on Michael Rothberg’s theorization of the implicated subject to explore how these digital documentaries bring the user into complicated relationality with national and international crises. Visually and experientially implying that users bear responsibility to the subjects and subject matter, these works can, on the one hand, replicate modes of liberal empathy for suffering, distant “others” and, on the other, simulate one’s own surveillant modes of observation or behavior to mirror it back to users and open up one’s offline thoughts and actions as a site of critique. This dissertation charts how second-person address shapes and limits the political potentialities of documentary projects and connects them to a lineage of direct address from educational and propaganda films, museum exhibits, and serious games. By centralizing the user’s individual experience, the interventions that second-person digital documentaries can make into social discourse change from public, institution-based education to more privatized forms of sentimental education geared toward personal edification and self-realization. Unless tied to larger initiatives or movements, I argue that digital documentaries reaffirm a neoliberal politics of individual self-regulation and governance instead of public education or collective, social intervention. Chapter one focuses on 360-degree virtual reality (VR) documentaries that utilize the feeling of presence to position users as if among refugees and as witnesses to refugee experiences in camps outside of Europe and various dwellings in European cities. My analysis of Clouds Over Sidra (Gabo Arora and Chris Milk 2015) and The Displaced (Imraan Ismail and Ben C. Solomon 2015) shows how these VR documentaries utilize observational realism to make believable and immersive their representations of already empathetic refugees. The empathetic refugee is often young, vulnerable, depoliticized and dehistoricized and is a well-known trope in other forms of humanitarian media that continues into VR documentaries. Forced to Flee (Zahra Rasool 2017), I am Rohingya (Zahra Rasool 2017), So Leben Flüchtlinge in Berlin (Berliner Morgenpost 2017), and Limbo: A Virtual Experience of Waiting for Asylum (Shehani Fernando 2017) disrupt easy immersions into realistic-looking VR experiences of stereotyped representations and user identifications and, instead, can reflect back the user’s political inaction and surveillant modes of looking. Chapter two analyzes web- and social media messenger-based documentaries that position users as outsiders to U.S. mass incarceration. Users are noir-style co-investigators into the crime of the prison-industrial complex in Fremont County, Colorado in Prison Valley: The Prison Industry (David Dufresne and Philippe Brault 2009) and co-riders on a bus transporting prison inmates’ loved ones for visitations to correctional facilities in Upstate New York in A Temporary Contact (Nirit Peled and Sara Kolster 2017). Both projects construct an experience of carceral constraint for users to reinscribe seeming “outside” places, people, and experiences as within the continuation of the racialized and classed politics of state control through mass incarceration. These projects utilize interfaces that create a tension between replicating an exploitative hierarchy between non-incarcerated users and those subject to mass incarceration while also de-immersing users in these experiences to mirror back the user’s supposed distance from this mode of state regulation. Chapter three investigates a type of digital game I term dataveillance simulation games, which position users as surveillance agents in ambiguously dystopian nation-states and force users to use their own critical thinking and judgment to construct the criminality of state-sanctioned surveillance targets. Project Perfect Citizen (Bad Cop Studios 2016), Orwell: Keeping an Eye on You (Osmotic Studios 2016), and Papers, Please (Lucas Pope 2013) all create a dual empathy: players empathize with bureaucratic surveillance agents while empathizing with surveillance targets whose emails, text messages, documents, and social media profiles reveal them to be “normal” people. I argue that while these games show criminality to be a construct, they also utilize a racialized fear of the loss of one’s individual privacy to make players feel like they too could be surveillance targets. Chapter four examines personalized digital documentaries that turn users and their data into the subject matter. Do Not Track (Brett Gaylor 2015), A Week with Wanda (Joe Derry Hall 2019), Stealing Ur Feelings (Noah Levenson 2019), Alfred Premium (Joël Ronez, Pierre Corbinais, and Émilie F. Grenier 2019), How They Watch You (Nick Briz 2021), and Fairly Intelligent™ (A.M. Darke 2021) track, monitor, and confront users with their own online behavior to reflect back a corporate surveillance that collects, analyzes, and exploits user data for profit. These digital documentaries utilize emotional fear- and humor-based appeals to persuade users that these technologies are controlling them, shaping their desires and needs, and dehumanizing them through algorithmic surveillance
