"This paper explores the distinction between operative and resultant actions in games, and proposes that the learning space created by a serious game is a function of these actions. Further, it suggests a possible relationship between these actions and the forms of cognitive load imposed upon the game player. Association of specific types of cognitive load with respective forms of actions in game mechanics also presents some heuristics for integrating learning content into serious games. Research indicates that different balances of these types of actions are more suitable for novice or experienced learners. By examining these relationships, we can develop a few basic principles of game design which have an increased potential to promote positive learning outcomes."

"This thesis proposes the development of a video game platform to increase the publics knowledge of required protective actions in the event of a nuclear terrorism attack. Current scientific analyses have identified elementary steps the public should take to increase the likelihood of survival in the event of a nuclear terrorism incident; however, a knowledge gap currently exists with regard to the publics understanding of these required actions. Unfortunately, todays preparedness initiatives do not have the efficacy required to impact significant improvements in this area. Video games, more specifically a sub-genre of games known as serious games, are uniquely postured to address this knowledge gap. Not only do video games provide a motivating, enriching and engaging educational medium, but also they are unique in that they address the emerging educational needs of todays games generation, which desires more interactive educational environments since they have been immersed in technology for the majority of their lives. As such, leveraging this technology can help close the current knowledge gap and increase the nations resilience to nuclear terrorism."

Abstract: "This article discusses the application of an Alexandrian pattern language to the design of interactive systems. It grew out of an University course titled A Pattern Approach to Action Game Design, which was offered as an elective in the Creative Technologies program at Auckland University of Technology, NZ, in 2011. We sketch out the idea of design patterns and describe our experiences with the process of using them for designing oldschool action games, that is, finding patterns, making a language, using it for creating several game designs and realizing one of these designs collaboratively. We discuss the concept of the course and present our pattern language and the game we made. While the language is arguably more like a patchy pattern collection, the various game designs quite loose and the realized game unfinished, the process was challenging and intense, and offered students a new perspective on design. In the spirit of design patterns, we only did what the task at hand required, not artificial exercises. We attempted to connect theory and practice in a natural, direct way as we presented, discussed and used everything we did in order to continue our journey. Our course was not aimed at fixed or frozen products, but on a process that is constantly in flux through collaboration by people who interact and share a common pattern language, use, test, revise and refine it while moving on."

"Create the Gotham for your Batman, the African savannah for your Simba, or the bustling newsroom for your Clark Kent. Background, setting, environment...whatever you call it, it is the silent character in the visual story, and a dynamic and compelling setting can define and hone the action and drama of your story."

Abstract: "Video games that customize to a player's experience level and abilities have the potential to allow a broader range of players to become engaged and maintain interest as they progress in experience level. A game that uniquely customizes the player's experience could attract additional demographics to gaming, which will result in a distinct edge in marketability and potential revenue. This thesis examines a subsection of adaptive gaming systems from the perspective of identifying game factors that alter the level of difficulty. Our focus is to provide a solution useful to both research and commercial gaming communities by developing a system that simulates results offline yet can be integrated into online play. While online performance is the main goal of an adaptive system, the offline simulation provides several benefits. Offline simulation allows the elimination of insignificant factors from inclusion in the training and evolution phase of machine learning algorithms. In addition it provides commercial games with a useful tool or method for performing game balancing and level tuning. To test our approach we designed a test-bed version of the game Pac-Man. The experimental testbed alters environment variables to evaluate their effect on a set of selected response variables. Observing the results of several response variables provides the potential to represent multiple player states, though our focus is on controlling the difficulty for a player. The testbed will simulate the actions of both Pac-Man and the ghosts over a variety of different settings and strategies. The evaluation of a factor's significance and its effect size are calculated using a factorial analysis approach. This method allows the identification of factors relevant to both individual strategies, and the set of all player strategies. Finally, as a proof of concept for both the online and adaptation prospects of this method, we developed a prototype adaptive system. Utilizing the releva

Abstract: "This paper demonstrates the use of a crowdsourced human computation game to accumulate annotations from non-experts as a means to provide labels for an affective facial expression database. To do so, a human computation game is played, in which players are encouraged to ask each other related facial expression questions. These questions are based on the Facial Action Coding System. Emphasis is placed on the participant's overall understanding of the task and on the ease-of-use of the game so that labeling accuracy is reinforced. Additional game mechanics can be used in future work to encourage players to keep playing the game. This crowdsourced labeling of an affective facial expressions database is important because the manual labeling of an affective database can be relatively expensive and time consuming. Our game shows that non-experts are comparable in labeling our affective database based on the ground truth."

Abstract: "Player coordination is a key element in many multi-player real-time digital games and cooperative real-time multi-player modes are now common in many digital-game genres. Coordination is an important part of the design of these games for several reasons: coordination can change the game balance and the level of difficulty as different types and degrees of coordination can make the game easier or more difficult; coordination is an important part of 'playing like a team' which affects the quality of play; and coordination as a shared activity is a key to sociality that can add to the sociability of the game. Being able to exercise control over the design of these coordination requirements is an important part of developing successful games. However, it is currently difficult to understand, describe, analyze or design coordination requirements in game situations, because current frameworks and theories do not mesh with the realities of video game design. I developed a new framework (called PLATO) that can help game designers to understand, describe, design and manipulate coordination episodes. The framework deals with five atomic aspects of coordinated activity: Players, Locations, Actions, Time, and Objects. PLATO provides a vocabulary, methodology and diagram notation for describing and analyzing coordination. I demonstrate the framework's utility by describing coordination situations from existing games, and by showing how PLATO can be used to understand and redesign coordination requirements."

Abstract: "Application domains for Computational Creativity projects range from musical composition to recipe design, but despite all of these systems having computational methods in com- mon, we are aware of no projects to date that focus on pro- gram code as the created artefact. We present the Mechanic Miner tool for inventing new concepts for videogame inter- action which works by inspecting, modifying and executing code. We describe the system in detail and report on an eval- uation based on a large survey of people playing games using content it produced. We use this to raise issues regarding the assessment of code as a created artefact and to discuss future directions for Computational Creativity research."

Abstract: "This paper describes the design and evaluation of Zoo U, a novel computer game to assess children's social skills development. Zoo U is an innovative product that combines theory-driven content and customized game mechanics. The game-like play creates the opportunity for stealth assessment, in which dynamic evidence of social skills is collected in real time and players' choices during gameplay provide the needed data. To ensure the development of an engaging and valid game, we utilized an iterative datadriven validation process in which the game was created, tested, revised based on student performance and feedback, and retested until game play was statistically matched to independent ratings of social skills. We first investigated whether the data collected through extensive logging of student actions provided information that could be used to improve the assessment. We found that detailed game logs of socially relevant player behavior combined with external measures of player social skills provided an efficient vector to incrementally improve the accuracy of the embedded assessments. Next, we investigated whether the game performance correlated with teachers' assessments of students' social skills competencies. An evaluation of the final game showed (a) significant correlations between in-game social skills assessments and independently obtained standard psychological assessments of the same students and (b) high levels of engagement and likeability for students. These findings support the use of the interactive and engaging computer game format for the stealth assessment of children's social skills. The created innovative design methodologies should prove useful in the design and improvement of computer games in education."

"In this paper we will discuss how positive psychology can contribute to the design of digital games and in particular training applications like Serious Games. While digital games have been known for their ability to deeply immerse users, stimulate the senses and tap into a broad range of emotions, it has proven rather challenging to use them as a vehicle for pedagogy. Relevant research is still at its infancy and many of the mechanisms that foster knowledge creation and enhance learning need to be mapped out before scripted in the game. The theory of psychological flow and the role of positive emotions in broadening people's thought-action repertoires bring some practical insights and pave the path for tackling some important de-sign questions. Yet there are still major challenges and uncharted waters to be explored in order for the technology to deliver what has been promised."

Abstract: "In recent years videogame companies have recognized the role of player engagement as a major factor in user experience and enjoyment. This en-couraged a greater investment in new types of game controllers such as the WiiMote™, Rock Band™ instruments and the Kinect™. However, the native software of these controllers was not originally designed to be used in other game applications. This work addresses this issue by building a middleware framework, which maps body poses or voice commands to actions in any game. This not only warrants a more natural and customized user-experience but it al-so defines an interoperable virtual controller. In this version of the framework, body poses and voice commands are respectively recognized through the Ki-nect's built-in cameras and microphones. The acquired data is then translated into the native interaction scheme in real time using a lightweight method based on spatial restrictions. The system is also prepared to use Nintendo's Wiimote™ as an auxiliary and unobtrusive gamepad for physically or verbally impractical commands. System validation was performed by analyzing the per-formance of certain tasks and examining user reports. Both confirmed this ap-proach as a practical and alluring alternative to the game's native interaction scheme. In sum, this framework provides a game-controlling tool that is totally customizable and very flexible, thus expanding the market of game consumers."

Published 2013 and excerpted in Google Books. "The book helps new programmers learn the concepts and techniques used to produce appealing 2D graphics. It starts with the basics and then covers topics pertaining to motion and depth, such as cel animation, tiling, and layering. The text also describes advanced graphics, including the use of particle systems, shaders, and splines. Code samples in the text and online allow readers to see a particular line of code in action or as it relates to the code around it. In addition, challenges and suggested projects encourage readers to work through problems, experiment with solutions, and tinker with code."

Abstract: "ideo games and other applications using off - the - shelf tracking devices often take a simple approach to gesture and pose recognition: a recognized gesture is always mapped to the same action . This approach basically turns a gesture into a binary button pre ss and misses much of the nuance implicit in natural gestures. In this paper we explore , in a game design setting , the use of continuous 3D gesture sequences where in attributes of individual gestures, such as speed, direction, etc., combine to influence th e r esult of the sequence as a whole . We present Pixelbending, a game demo built using the Microsoft Kinect and Unreal Developers Kit (UDK) in which the player performs Tai Chi inspired movements to control water. Designed with the goal of creating a fun an d engaging 3D game experience built on a nuanced gesture set, the demo was well received by many players of different ages and sizes. Through the development process we encountered challenges to working with off - the - shelf devices."

Abstract: "Reality-based interfaces bring new design opportunities to social games. These novel game interfaces, exemplified by Wii, Kinect, and Smart phones, leverage players' existing physics, bodily, environmental, and social skills. Moreover, they enable a shared hybrid physical-digital space in which the players' co-presence can be enhanced by their physical and digital co-location. However, many digital social games occupy players' attention with the digital display and content, reducing their attention spent on one another and limiting the synchronization of actions and emotions among players. How do we design technologies that do not interfere with social play but enhance and innovate it? In this thesis work, I focus on one particular kind of reality-based interfaces, Handheld Augmented Reality (HAR), to extend players' interaction from the small mobile devices to the shared hybrid space around a computationally trackable surface. This thesis explores how to encourage social play with HAR interfaces, which brings in challenges of designing with the affordances and constraints of the HAR interface, understanding the complicated phenomenon of social play, and integrating these understandings in multiplayer HAR game design. Adopting Research-through Design as the overarching research method, I collaborate with multiple teams, design and study three multiplayer HAR game prototypes. I present four main contributions. First, this work yields design artifacts and examples of social games with HAR interfaces. I communicate to the game design and Augmented Reality communities through these prototypes, including BragFish, ARt of Defense, and NerdHerder. Second, I provide empirical findings on social play in a shared hybrid space. Through lab-based user studies, observation, video analysis, interviews, and surveys, I collect and analyze interpersonal play behaviors and emotions in the shared hybrid space enabled by the HAR interface. Third, I adopt and adapt sociologic

Abstract: "Persuasive games are an effective approach for motivating health behavior, and recent years have seen an increase in games designed for changing human behaviors or attitudes. However, these games are limited in two major ways: first, they are not based on theories of what motivates healthy behavior change. This makes it difficult to evaluate why a persuasive approach works. Second, most persuasive games treat players as a monolithic group. As an attempt to resolve these weaknesses, we conducted a large-scale survey of 642 gamers' eating habits and their associated determinants of healthy behavior to understand how health behavior relates to gamer type. We developed seven different models of healthy eating behavior for the gamer types identified by BrainHex. We then explored the differences between the models and created two approaches for effective persuasive game design based on our results. The first is a one-size-fits-all approach that will motivate the majority of the population, while not demotivating any players. The second is a personalized approach that will best motivate a particular type of gamer. Finally, to make our approaches actionable in persuasive game design, we map common game mechanics to the determinants of healthy behavior."

"Physics engines have created a whole new source of emergence and fun for digital games. Water simulation could add another similar emergent interaction element, but it is currently only rarely used as a part of gameplay. The reasons for this are analysed and different water simulation methods are compared, focusing on actual game usage. Based on this, we suggest using the extremely simple but fast pipe model. The simplicity of the underlying simulation can be masked in many ways using modern shader effects and other tricks. An example of the pipe method in action is given and compared to more sophisticated fluid solvers."

"construction of a social cues and training demonstrator (a serious game) that enables its users to improve their social behaviour. In this report, a distinction is made between strong story and strong autonomy approaches to narrative management. The former rely on central management of the narrative through drama managers, not giving their agents much freedom. Inversely, the latter focus on the autonomy of agents, without explicit top-down control over the narrative. The autonomy of such agents allows an unscripted narrative to emerge from the user's interaction with the system. The trade-off between a strict storyline and freedom of action in these approaches is called the narrative paradox. It is concluded that a strong autonomy approach can feature social behaviour of agents more easily than a strong story one, because it is inherent with this approach that its agents have more complex models. For the demonstrator, some control over the narrative is required to let its users reach given goals in the created scenarios. Therefore, our future work will focus on creating a hybrid approach that enables agents to direct the story autonomously."
