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: "Abstract-In computer games and simulations, content is often rather static and rigid. As a result, its prescripted nature can lead to predictable and impersonal gameplay, while alienating unconventional players. Adaptivity in games has therefore been recently proposed to overcome these shortcomings and make games more challenging and appealing. In this paper, we survey present research on game adaptivity, identifying, and discussing the main challenges, and pointing out some of the most promising directions ahead.We first survey the purposes of adaptivity, as the principles that could steer an adaptation and generation engine. From this perspective, we proceed to thoroughly discuss adaptivity's targets and methods. Current advances and successes in this emerging field point to many yet unexplored research opportunities. Among them, we discuss the use of gameplay expectations, learning preferences, and assessment data in the integrated adaptation of game worlds, scenarios, and quests. We conclude that, among other methods, procedural content generation and semantic modeling can powerfully combine to create offline customized content and online adjustments to game worlds, scenarios, and quests. These and other promising methods, deserving ample research efforts, can therefore, be expected to significantly contribute towards making games and simulations even more unpredictable, effective, and fun."

From the abstract: "In this paper, we propose the integration of two PCG-based approaches (experiencedriven and context-driven PCG) to support the generation of adaptive mobile game levels. We present and discuss the implementation of our approach in an existing game, 7's Wild Ride. Gameplay semantics and player modeling are used to steer a level generator, featuring a time-dependent dynamic diculty adjustment mechanism. From our two user studies, we conclude that (i) context-driven levels are preferable over traditional ones, and (ii) the game can adapt to dierent player types, keeping its gameplay balanced and player satisfaction."

Abstract: "This paper introduces Rank-based Interactive Evo- lution (RIE) which is an alternative to interactive evolution driven by computational models of user preferences to generate personalized content. In RIE, the computational models are adapted to the preferences of users which, in turn, are used as fitness functions for the optimization of the generated content. The preference models are built via ranking-based preference learning, while the content is generated via evolutionary search. The proposed method is evaluated on the creation of strategy game maps, and its performance is tested using artificial agents. Results suggest that RIE is both faster and more robust than standard interactive evolution and outperforms other state-of- the-art interactive evolution approaches"

Abstract: "With the increasing potential for gaming hardware and peripherals to support biometrics, their application within the games industry for software and design should be considered. This pa per assesses the ability to use a form of biometric measurement, heart rate, in real - time to improve the challenge and enjoyment of a game by catering it to individuals of varying ability . While the findings of this study are valuable to game developers in terested in providing additional dimensions to gameplay and testing, they may also be useful for those researching medical or the rapeutic applications for games . The results suggest that although the tested game was inherently challenging and enjoyable, t he adaptive affective gameplay was not altering the game enough to induce strong physiological or emotional responses from participants. Biofeedback games lend themselves to medical applications, but adaptive affective games can be used to respond sympathe tically to the player without requiring direct control of physiological responses as a form of input."

From the abstract :"The Vikings! is an asynchronous multiplayer social game that adapts Viking Age (700s-1000s C.E.) social practices and structures in the hopes of producing a synthetic Viking society. Players manage Viking households, sail the open seas, raid Viking and foreigner households, and develop economic and political relationships with other players to ensure their own survival and prosperity. To successfully prosecute this project, the author came to devise: a semi-formal method for adapting historical situations to interactive simulations; a set of criteria for evaluating the quality, internal consistency, and historical fidelity of such simulations; and a technique for constraining the scope of adaptation to only what is necessary for the player's enjoyment and the designer's aesthetic goals."

"We propose a course design that ts a practical game development project into a regular game design lecture course. As this approach requires a consistent structure, our concept proposes an adaption of Scrum that is based on the game development life-cycle: ABC-Sprints consist of three Sprints to iteratively create Alpha, Beta and Completed versions of a game. We present a detailed walkthrough of the course and give results of a formal evaluation. These indicate that ABC-Sprints help students to manage their workload and to increase productivity over time. Consequently, three teams each presented a game at the end of the course that technically exceeded typical outcomes of game projects without lectures. We hence encourage to apply ABC-Sprints to other curricula and provide a set of recommendations."

Abstract: "This study develops a way to use the technology of video games to help teach people the violin. The unique characteristics of this research are to create a visual representation for music for violinists, to utilize pedagogy for violin education within a video game, and to use the Fast Fourier Transform to process input from an actual acoustic instrument and use the data to track user progress. Music games like JamGuru [9], Rocksmith [19], LittleBigStar [13], and Rock Band [18] have made strides in these areas of research; however, most of these technologies have not been applied to the violin. Expected results are that students' progress rate will increase as a result of playing the game. The input processing used in this research could be applied to areas where sound recognition is important. Furthermore, the concept of an adaptable game can be applied to other academic subjects."

Abstract: "In this paper, we describe a methodology for capturing player experience while interacting with a game and we present a data-driven approach for modeling this interaction. We believe the best way to adapt games to a specic player is to use quantitative models of player ex- perience derived from the in-game interaction. Therefore, we rely on crowd-sourced data collected about game context, players behavior and players self-reports of dierent aective states. Based on this informa- tion, we construct estimators of player experience using neuroevolution- ary preference learning. We present the experimental setup and the re- sults obtained from a recent case study where accurate estimators were constructed based on information collected from players playing a rst- person shooter game. The framework presented is part of a bigger picture where the generated models are utilized to tailor content generation to particular player's needs and playing characteristics."

"Game-based simulation systems are increasingly being used to train users in several applications across government, in- dustry, and academia. Designing game-based training sys- tems that can measurably improve learning while providing an engaging training experience is a challenging problem. In this paper, we describe a novel framework that tightly inte- grates game-based training systems with instructional com- ponents using data analysis to address this problem. Intelli- gent training systems based on this framework dynamically adapt both the training and the instructional components to measurably improve learning in play sessions. We propose a three phase approach to automatically identify points in a play session to predict high-value future scenarios, validate predictions, and prescribe actions. A case study using the KDD Cup 2010 educational data set is described illustrating the e®ectiveness of the proposed approach."

Abstract: "The rising acceptance of Virtual Learning Environments (VLE) in the e- Learning field poses new challenges such as producing student-centered courses which can be automatically tailored to each student's needs. For this purpose digital games can be used, taking advantage of their flexibility (good video games always try to adapt to different players) and capabilities to stealthily track players' activity, either for producing an accurate user model or enhancing the overall assessment capabilities of the system. In this chapter we discuss the integration of digital games in Virtual Learning Environments and the need of standards that allow the interoperable communication of games and VLE. We also present a middle-ware architecture to integrate video games in VLEs that addresses the technical barriers posed by the integration. We present a case study with the implementation of the architecture in the game authoring platform, along with three examples of video game integration in educational settings"

"Smartphone devices are becoming the de facto personal com- puting platform, rivaling the desktop, as the number of smartphone users is projected to reach 1.1 billion by 2013. Unlike the desktop, smartphones have a constrained energy budget, which is further challenged by increasingly sophisti- cated applications. Amongst the most popular applications on smartphone devices are games and virtual environments that rely on 3D graphics. Due to the computational inten- sity of geometry and rasterization, as well as the perpetually illuminated display, these applications are extremely power- hungry. To prolong the battery life of devices running these applications, we propose two new energy-aware adaptation schemes that can be employed in 3D graphics applications: lighting limitation and textural transformation. Our results show that we can conserve between 20% and 33% of energy with acceptable sacrices to a user's visual experience."
