Feedback-Based Gameplay Metrics and Gameplay Performance Segmentation: An audio-visual approach for assessing player experience.

Gameplay metrics is a method and approach that is growing in popularity amongst the game studies research community for its capacity to assess players’ engagement with game systems. Yet, little has been done, to date, to quantify players’ responses to feedback employed by games that conveys information to players, i.e., their audio-visual streams. The present thesis introduces a novel approach to player experience assessment - termed feedback-based gameplay metrics - which seeks to gather gameplay metrics from the audio-visual feedback streams presented to the player during play. So far, gameplay metrics - quantitative data about a game state and the player's interaction with the game system - are directly logged via the game's source code. The need to utilise source code restricts the range of games that researchers can analyse. By using computer science algorithms for audio-visual processing, yet to be employed for processing gameplay footage, the present thesis seeks to extract similar metrics through the audio-visual streams, thus circumventing the need for access to, whilst also proposing a method that focuses on describing the way gameplay information is broadcast to the player during play. In order to operationalise feedback-based gameplay metrics, the present thesis introduces the concept of gameplay performance segmentation which describes how coherent segments of play can be identified and extracted from lengthy game play sessions. Moreover, in order to both contextualise the method for processing metrics and provide a conceptual framework for analysing the results of a feedback-based gameplay metric segmentation, a multi-layered architecture based on five gameplay concepts (system, game world instance, spatial-temporal, degree of freedom and interaction) is also introduced. Finally, based on data gathered from game play sessions with participants, the present thesis discusses the validity of feedback-based gameplay metrics, gameplay performance segmentation and the multi-layered architecture. A software system has also been specifically developed to produce gameplay summaries based on feedback-based gameplay metrics, and examples of summaries (based on several games) are presented and analysed. The present thesis also demonstrates that feedback-based gameplay metrics can be conjointly analysed with other forms of data (such as biometry) in order to build a more complete picture of game play experience. Feedback based game-play metrics constitutes a post-processing approach that allows the researcher or analyst to explore the data however they wish and as many times as they wish. The method is also able to process any audio-visual file, and can therefore process material from a range of audio-visual sources. This novel methodology brings together game studies and computer sciences by extending the range of games that can now be researched but also to provide a viable solution accounting for the exact way players experience games

Offene-Welt-Strukturen: Architektur, Stadt- und Naturlandschaft im Computerspiel

Welche Rolle spielen Algorithmen für den Bildbau und die Darstellung von Welt und Wetter in Computerspielen? Wie beeinflusst die Gestaltung der Räume, Level und Topografien die Entscheidungen und das Verhalten der Spieler_innen? Ist der Brutalismus der erste genuine Architekturstil der Computerspiele? Welche Bedeutung haben Landschaftsgärten und Nationalparks im Strukturieren von Spielwelten? Wie wird Natur in Zeiten des Klimawandels dargestellt? Insbesondere in den letzten 20 Jahren adaptieren digitale Spielwelten akribischer denn je Merkmale der physisch-realen Welt. Durch aufwändige Produktionsverfahren und komplexe Visualisierungsstrategien wird die Angleichung an unsere übrige Alltagswelt stets in Abhängigkeit von Spielmechanik und Weltlichkeit erzeugt. Wie sich spätestens am Beispiel der Open-World-Spiele zeigt, führt die Übernahme bestimmter Weltbilder und Bildtraditionen zu ideologischen Implikationen, die weit über die bisher im Fokus der Forschung stehenden, aus anderen Medienformaten transferierten Erzählkonventionen hinausgehen. Mit seiner Theorie der Architektur als medialem Scharnier legt der Autor offen, dass digitale Spielwelten medienspezifische Eigenschaften aufweisen, die bisher nicht zu greifen waren und der Erforschung harrten. Durch Verschränken von Konzepten aus u.a. Medienwissenschaft, Game Studies, Philosophie, Architekturtheorie, Humangeografie, Landschaftstheorie und Kunstgeschichte erarbeitet Bonner ein transdisziplinäres Theoriemodell und ermöglicht anhand der daraus entwickelten analytischen Methoden erstmals, die komplexe Struktur heutiger Computerspiele - vom Indie Game bis zur AAA Open World - zu verstehen und zu benennen. Mit "Offene-Welt-Strukturen" wird die Architektonik digitaler Spielwelten umfassend zugänglich

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse
