Autorenumgebung für Serious Games - StoryTec: Eine Autorenumgebung und narrative Objekte für personalisierte Serious Games

Serious Games vereinen die Charakteristik von Unterhaltungsspielen mit einem „characterizing goal“ und Spezifika dedizierter Serious Games Anwendungsbereiche. Das Potential von Serious Games ist groß, dennoch ist die Qualität oftmals nicht optimal und die Nutzerakzeptanz entsprechend gering. Auch gibt es oftmals eine falsche Erwartungshaltung gegenüber Serious Games im Hinblick auf das Kosten-Nutzenverhältnis und auf notwendige Entwicklungsbudgets für Serious Games. Daher sind innovative Methoden, Konzepte und Technologien erforderlich, die signifikant zur Qualitätssteigerung und der erfolgreichen Verbreitung von Serious Games beitragen. Im Rahmen dieser Arbeit werden hierfür mit der Autorenumgebung StoryTec und dem Modell für narrative Objekte eigene Forschungsbeiträge zur Erstellung, Steuerung und Evaluation von personalisierten, adaptiven Serious Games vorgestellt. Basierend auf dieser Ausgangssituation werden in Kapitel 2 Serious Games Technologien als Lösungsansätze zur Erstellung, Steuerung und Evaluation von Serious Games beschrieben und die eigene Arbeit in dieses komplexe Forschungsfeld eingeordnet. Kapitel 3 und 4 beschreiben die Autorenumgebung „StoryTec“ und das Modell der „Narrative Game-based Learning Objects“ (NGLOB). StoryTec fungiert als Rapid Prototyping Umgebung, bestehend aus dem Authoring Tool „StoryTec Editor“ und den beiden Abspielkomponenten (Player) „StoryPublish“ und „StoryPlay“, die speziell Autoren ohne Programmierkenntnisse bei der Entwicklung von Serious Games unterstützen. NGLOBs dienen als konzeptionelle Grundlage von personalisierten Story-basierten Lernspielen; sie vereinen narrative dramaturgische Aspekte mit benutzerindividuellen Spieler- und Lernermodellen. Das NGLOB-Konzept wurde prototypisch realisiert und vollständig in StoryTec integriert. In Kapitel 5 „Serious Games für Bildung und Gesundheit“ werden die erarbeiteten Methoden und Konzepte anhand des Geographie-Lernspiels „80Days“ und dem personalisierten Bewegungsspiel „ErgoActive“ validiert. Abschließend werden die wesentlichen Ergebnisse der Arbeit zusammengefasst und ein Ausblick für weiterführende Forschungsarbeiten skizziert – u.a. im Hinblick auf die Konzeption eines Metadaten-gestützten Informationssystems für Serious Games, das eine (standardisierte) Beschreibung und (individuelle) Suche nach (geeigneten) Serious Games ermöglicht

Users' performance of accessible sound-only computer games

This work is conducted at two levels to meet the requirements of this research. The first objective is to develop a better understanding of how to design better sound-only games for a wide range of users. A new theoretical framework has been crafted to achieve this objective (Human Understanding Theory of Novel Games with Simplex, or the HUNGS theory). Such a theory aims to capture the current consensus about user requirements (as far as it is possible to do so) whilst understanding the principles and practices of interactive systems, namely the design of accessible sound-only games. The second objective is to understand better the psychology of intended users of such games. The importance of the present work is to test psychological concepts in the very different and very popular context of computer games. Implications found for users at work or working on serious tasks may not generalize to game players. To achieve the second requirement, a number of existing games were explored before a new game was designed (namely the Totally Lost game), using a range of methods. The Totally Lost game and different versions of the same game have been designed and evaluated based on user experiences

Virtual Heritage: new technologies for edutainment

Cultural heritage represents an enormous amount of information and knowledge. Accessing this treasure chest allows not only to discover the legacy of physical and intangible attributes of the past but also to provide a better understanding of the present. Museums and cultural institutions have to face the problem of providing access to and communicating these cultural contents to a wide and assorted audience, meeting the expectations and interests of the reference end-users and relying on the most appropriate tools available. Given the large amount of existing tangible and intangible heritage, artistic, historical and cultural contents, what can be done to preserve and properly disseminate their heritage significance? How can these items be disseminated in the proper way to the public, taking into account their enormous heterogeneity? Answering this question requires to deal as well with another aspect of the problem: the evolution of culture, literacy and society during the last decades of 20th century. To reflect such transformations, this period witnessed a shift in the museum’s focus from the aesthetic value of museum artifacts to the historical and artistic information they encompass, and a change into the museums’ role from a mere "container" of cultural objects to a "narrative space" able to explain, describe, and revive the historical material in order to attract and entertain visitors. These developments require creating novel exhibits, able to tell stories about the objects and enabling visitors to construct semantic meanings around them. The objective that museums presently pursue is reflected by the concept of Edutainment, Education + Entertainment. Nowadays, visitors are not satisfied with ‘learning something’, but would rather engage in an ‘experience of learning’, or ‘learning for fun’, being active actors and players in their own cultural experience. As a result, institutions are faced with several new problems, like the need to communicate with people from different age groups and different cultural backgrounds, the change in people attitude due to the massive and unexpected diffusion of technology into everyday life, the need to design the visit by a personal point of view, leading to a high level of customization that allows visitors to shape their path according to their characteristics and interests. In order to cope with these issues, I investigated several approaches. In particular, I focused on Virtual Learning Environments (VLE): real-time interactive virtual environments where visitors can experience a journey through time and space, being immersed into the original historical, cultural and artistic context of the work of arts on display. VLE can strongly help archivists and exhibit designers, allowing to create new interesting and captivating ways to present cultural materials. In this dissertation I will tackle many of the different dimensions related to the creation of a cultural virtual experience. During my research project, the entire pipeline involved into the development and deployment of VLE has been investigated. The approach followed was to analyze in details the main sub-problems to face, in order to better focus on specific issues. Therefore, I first analyzed different approaches to an effective recreation of the historical and cultural context of heritage contents, which is ultimately aimed at an effective transfer of knowledge to the end-users. In particular, I identified the enhancement of the users’ sense of presence in VLE as one of the main tools to reach this objective. Presence is generally expressed as the perception of 'being there', i.e. the subjective belief of users that they are in a certain place, even if they know that the experience is mediated by the computer. Presence is related to the number of senses involved by the VLE and to the quality of the sensorial stimuli. But in a cultural scenario, this is not sufficient as the cultural presence plays a relevant role. Cultural presence is not just a feeling of 'being there' but of being - not only physically, but also socially, culturally - 'there and then'. In other words, the VLE must be able to transfer not only the appearance, but also all the significance and characteristics of the context that makes it a place and both the environment and the context become tools capable of transferring the cultural significance of a historic place. The attention that users pay to the mediated environment is another aspect that contributes to presence. Attention is related to users’ focalization and concentration and to their interests. Thus, in order to improve the involvement and capture the attention of users, I investigated in my work the adoption of narratives and storytelling experiences, which can help people making sense of history and culture, and of gamification approaches, which explore the use of game thinking and game mechanics in cultural contexts, thus engaging users while disseminating cultural contents and, why not?, letting them have fun during this process. Another dimension related to the effectiveness of any VLE is also the quality of the user experience (UX). User interaction, with both the virtual environment and its digital contents, is one of the main elements affecting UX. With respect to this I focused on one of the most recent and promising approaches: the natural interaction, which is based on the idea that persons need to interact with technology in the same way they are used to interact with the real world in everyday life. Then, I focused on the problem of presenting, displaying and communicating contents. VLE represent an ideal presentation layer, being multiplatform hypermedia applications where users are free to interact with the virtual reconstructions by choosing their own visiting path. Cultural items, embedded into the environment, can be accessed by users according to their own curiosity and interests, with the support of narrative structures, which can guide them through the exploration of the virtual spaces, and conceptual maps, which help building meaningful connections between cultural items. Thus, VLE environments can even be seen as visual interfaces to DBs of cultural contents. Users can navigate the VE as if they were browsing the DB contents, exploiting both text-based queries and visual-based queries, provided by the re-contextualization of the objects into their original spaces, whose virtual exploration can provide new insights on specific elements and improve the awareness of relationships between objects in the database. Finally, I have explored the mobile dimension, which became absolutely relevant in the last period. Nowadays, off-the-shelf consumer devices as smartphones and tablets guarantees amazing computing capabilities, support for rich multimedia contents, geo-localization and high network bandwidth. Thus, mobile devices can support users in mobility and detect the user context, thus allowing to develop a plethora of location-based services, from way-finding to the contextualized communication of cultural contents, aimed at providing a meaningful exploration of exhibits and cultural or tourist sites according to visitors’ personal interest and curiosity

Providing Hints, Next Steps and Feedback in a Tutoring System for Structural Induction

Structural induction is a proof technique that is widely used to prove statements about discrete structures. Students find it hard to construct inductive proofs, and when learning to construct such proofs, receiving feedback is important. In this paper we discuss the design of a tutoring system, LogInd, that helps students with constructing stepwise inductive proofs by providing hints, next steps and feedback. As far as we know, this is the first tutoring system for structural induction with this functionality. We explain how we use a strategy to construct proofs for a restricted class of problems. This strategy can also be used to complete partial student solutions, and hence to provide hints or next steps. We use constraints to provide feedback. A pilot evaluation with a small group of students shows that LogInd indeed can give hints and next steps in almost all cases.Comment: In Proceedings ThEdu'19, arXiv:2002.1189

Human Factors in Agile Software Development

Through our four years experiments on students' Scrum based agile software development (ASD) process, we have gained deep understanding into the human factors of agile methodology. We designed an agile project management tool - the HASE collaboration development platform to support more than 400 students self-organized into 80 teams to practice ASD. In this thesis, Based on our experiments, simulations and analysis, we contributed a series of solutions and insights in this researches, including 1) a Goal Net based method to enhance goal and requirement management for ASD process, 2) a novel Simple Multi-Agent Real-Time (SMART) approach to enhance intelligent task allocation for ASD process, 3) a Fuzzy Cognitive Maps (FCMs) based method to enhance emotion and morale management for ASD process, 4) the first large scale in-depth empirical insights on human factors in ASD process which have not yet been well studied by existing research, and 5) the first to identify ASD process as a human-computation system that exploit human efforts to perform tasks that computers are not good at solving. On the other hand, computers can assist human decision making in the ASD process.Comment: Book Draf

E-learning and motivation: a multi-faceted investigation of eleven to fourteen year olds' attraction to computer-based learning, and their motivational responses to the novelty and nature of a selection of self-study computer-based learning activities.

Are eleven to fourteen year old learners attracted to computers? Can computers motivate them to learn? How do they respond to new self-study, computer-based learning activities? Does the type of computer-based learning activity affect their motivation? This study focuses on three important facets of e-learning and motivation – attraction, novelty and activities. The first facet (attraction) relates to verifying the existence of, and reasons for, the attraction to computers. Further areas of investigation relate to the effects of this attraction (if it exists) and learners’ perceptions of proficiency on motivation. The second facet (novelty) relates to learners’ perceptions of novelty and responses to different types of novel self-study, computer-based learning activities. Activities (the third facet) relates to the motivational effects of different types of self-study, computer-based learning activities. The study took place in three schools in different geographical areas of the United Kingdom. The participants were eleven to fourteen year olds. The first facet (attraction) was approached using surveys, through online questionnaires and focus group interviews. The second and third facets (novelty and activities) were approached through multiple-case studies, mainly through observations, self-report forms, and focus group interviews. An important finding is that most learners are attracted to computers, but not necessarily motivated to learn with computers. It is argued that today’s learners have learning attitudes that are based around fun. Hence, e-learning must accommodate this whilst delivering “serious learning”. The research evidence also show differences in perceived novelty and motivational effects of different types of e-learning activities. In particular, the research evidence suggests that the perception of novelty can be extended by changes or discussions during the interaction with certain activities (“regenerative novelty”). It is argued that knowledge of the novelty and motivational effects should be harnessed to provide engagement with learning

Designing engaging experiences with location-based augmented reality games for urban tourism environments.

Gameplay has recently unfolded as playfulness in various cultural forms using mobile technologies. The rapid affordability paired with the latest technology improvements enabled the diffusion of mobile devices among tourists, who are among the most avid users of mobile technologies. The advent of mobile devices has initiated a significant change in the way we perceive and connect with our environment and paved the way for location-based, mobile augmented reality (AR) games that provide new forms of experiences for travel and tourism. With the recent developments like Pokémon Go and a prediction of 420 million downloads per year by 2019, the mobile game market is one of the fastest growing fields in the sector. Location-based AR games for mobile devices make use of players‟ physical location via the GPS sensor, accelerometer and compass to project virtual 2D and 3D objects with the build-in camera in real time onto the mobile game user interface (GUI) in order to facilitate gameplay activities. Players interact with the virtual and physical game world and overcome artificial challenges while moving around in the real environment. Where current mobile games withdraw players from reality, location-based AR games aim to engage players with the physical world by combining virtual and physical game mechanics in an enhanced way that increases the level of interactive educative and entertaining engagement. Despite some recent research on location-based AR games, game designers do not know much about how to address tourism requirements and the development of mediated playful experiences for urban tourism environments. This study explores the use of location-based AR games to create engaging and meaningful experiences with the tourism urban environment by combining interdisciplinary research of social sciences, (mobile) game design and mobile game user research (mGUR) to contribute to experience design in the context of travel and tourism. Objectives of the study are to identify the influence of key game elements and contextual gameplay parameters on the individual game experience (GX). To achieve the aim, the study has taken a pragmatic interpretivist approach to understand the player‟s individual GX in an evolving gameplay process in order to inform location-based game design. The project explores the interaction between the player, the game and the tourism context, which is assessed by a sequential triangulation of qualitative mixed methods. Two games were identified to be relevant for the tourism application that fulfilled the attributes of a location-based AR game. The first game is a role-playing adventure game, set in the time and place of the Cold War, called Berlin Wall 1989. The second game, Ingress, is a fictive, large area, massively multiplayer role-playing game that uses the real world as the battleground between two game fractions. A conceptual framework has been developed that presents the player engagement process with location-based AR games in urban tourism environments. The findings of the study indicate that gameplay is a moment-by-moment experience that is influenced by multiple aspects. The creation of engaging experiences between players, the game and the tourism context is related to six identified engagement characteristics; emotional engagement, ludic engagement, narrative engagement, spatial engagement, social engagement and mixed reality engagement. The study identified that the main motivations of playing a location-based AR game are the exploration of and learning about the visited destination, curiosity about the new playful activity and socialising with other players. Emotions underlie the creation of engagement stimulated by the alteration of playful interactions. The findings revealed that storytelling and simple game mechanics such as walking, feedback and goal orientation are essential elements in the creation of engaging experiences. Augmented reality, as a feature to connect the real with the virtual world, needs to create real added value for the gameplay in order to be perceived as engaging for players. The study proposes serious location-based AR games as an alternative form for tourism interpretation and has showed opportunities to enhance the tourist experience through self-directed, physical and mental interaction between players, the environment and the location-based AR game. The findings of the research illustrate the complexity of designing location-based game experiences. The developed conceptual framework can be used to inform future location-based AR game design for travel and tourism
