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."

Abstract :"Petri nets are graphical and mathematical tool for modeling, analyzing, and designing discrete event applicable to many systems. They can be applied to game design too, especially to design serous game. This paper describes an alternative approach to the modeling of serious game systems and classification of motivation behavior with Petri nets. To assess the motivation level of player ability, this research aims at Motivation Behavior Game (MBG). MBG improves this motivation concept to monitor how players interact with the game. This modeling employs Learning Vector Quantization (LVQ) for optimizing the motivation behavior input classification of the player. MBG may provide information when a player needs help or when he wants a formidable challenge. The game will provide the appropriate tasks according to players' ability. MBG will help balance the emotions of players, so players do not get bored and frustrated. Players have a high interest to finish the game if the players are emotionally stable. Interest of the players strongly supports the procedural learning in a serious game."

Abstract: "Herein is proposed the creation of an Application Program- ming Interface (API) for the Unity 3 and 4 video game de- velopment engine that not only reads behavioral measures from traditional video game input devices (such as if there has been an increase in mouse movements and clicks) but also takes into account physiological measures from biomet- ric devices (such as an increase in respiratory rate). The API parses these inputs based on study results that correlated player performance and engagement with physio- logical signs across several dierent game genres. Through the use of several rudimentary machine learning algorithms, raw physiological data is transformed into data relevant to a developer, including player engagement. The results of these calculations allow a game designer to have powerful tools for detecting when players experience certain emotions, and al- low for the design of aective games. Furthermore, the API also exposes the raw data to de- velopers wishing to propose and utilize their own learning algorithms, to allow for a rich development environment for developers of all skill levels. These development tools will enrich the game experience for the player, as well as prepare designers for the use of the next wave of non-traditional in- put hardware. This report serves to illustrate the current status of the API. A brief overview of the signicance of galvonic skin re- sponse (GSR), heart rate (HR), and respiratory rate (RR) in detecting player performance and engagement will be fol- lowed by a discussion of the API itself and the design choices therein."

Research shows that violent video games increase aggressive behavior and decrease prosocial behavior, but could relaxing video games have the opposite effects? In two experiments, participants were randomly assigned to play a relaxing, neutral, or prosocial video game for 20 min.

A dystopia based on investigation into behavioral economics that envisions video games that are "compelling" and addictive but not fun and rewarding

"The UT^2 game bot, created by computer scientists Jacob Schru, Igor Karpov and Risto Miikkulainen, won the Humanlike Bot Competition at the IEEE World Congress on Computational Intelligence (WCCI 2012). "The idea of the competition is to evaluate how we can make game bots, non-player characters (NPCs) controlled by AI algorithms, appear as human as possible," explains Miikkulainen, professor of computer science in the College of Natural Sciences. "It is generally recognized that NPCs are relatively weak in most video games: their behavior is predictable and mechanical, and they often make mistakes that human players would be unlikely to make. Players often enjoy playing against other humans, because it provides a more interesting game experience. The goal of the competition is to promote more research in human-like bots, as well as evaluate how well we are currently doing in this area."

Abstract: "Adolescent obesity is an increasing challenge, and pervasive social health games hold much promise for promoting sustained healthy behaviors. Researchers and d esigners of these systems have many potential theories and existing best practices at their disposal. Our study, grounded in participatory design, shows which ones matter - both for pervasive social health games and within the cultural context of a community we studied over the course of three years. We worked with 112 US middle school students from a lower - income community in a series of participatory design exercises focused on social rewards for everyday physical activity. In our analysis, we discuss design implications in four key areas : social presence, gender effects, incentives and competition. We show how these themes manifested in students' designs and why they were particularly important to our participa nts. We then use our findings to suggest design strategies for youth - focused pervasive social health games."

As the game models player behavior it can use that data to encourage desired behavior, specifically for wellness apps

"Abstract: Previous research proposes that human beings are motivated to protect endangered species by both instrumental values and intrinsic values of biodiversity. However, it has been difficult to tease apart the two kinds of value at the behavioral level. Using an innovative fishing game, we tested one kind of instrumental value (financial value) and one kind of intrinsic value (existence value) of the endangered Steller sea lion. In the fishing game, players make repeated decisions on how much Pollock to harvest for profit in each period in a dynamic ecosystem. The population of the endangered sea lion depends on the population of Pollock, which in turn depends on the harvesting behavior of humans. The data show that in general, people responded to the financial value, but not the existence value, of the sea lion by cutting down commercial fish harvesting to keep more sea lions in the ecosystem. However, not all people behaved the same regarding the existence value. Females displayed a higher existence value than males, as did people who reported stronger proenvironmental attitudes than those with less pro‐environmental attitudes. Our findings have multiple implications on public opinion elicitation and public policy design."

Abstract: "Computer based video games are receiving great interest as a means to learn and acquire new skills. As a novel approach to teaching navigation skills in the blind, we have developed Audio-based Environment Simulator (AbES); a virtual reality environment set within the context of a video game metaphor. Despite the fact that participants were naïve to the overall purpose of the software, we found that early blind users were able to acquire relevant information regarding the spatial layout of a previously unfamiliar building using audio based cues alone. This was confirmed by a series of behavioral performance tests designed to assess the transfer of acquired spatial information to a large-scale, real-world indoor navigation task. Furthermore, learning the spatial layout through a goal directed gaming strategy allowed for the mental manipulation of spatial information as evidenced by enhanced navigation performance when compared to an explicit route learning strategy. We conclude that the immersive and highly interactive nature of the software greatly engages the blind user to actively explore the virtual environment. This in turn generates an accurate sense of a large-scale three-dimensional space and facilitates the learning and transfer of navigation skills to the physical world."

From the abstract: "This thesis is dealing with what have been identified as "pervasive games". Investigation and analysis of reasons behind their appearance, popularization is made. Different trends within classical game-development and theory of classical game-design are investigated to establish similarities and differences, challenges and solutions this newly emerged type of games is introducing. Knowledge presented in theoretical sections is used to design, develop, deploy and test a game-environment for mobile platforms that is adjusted for campus area. This designed game-environment consists of two essential components: Front-End, which is represented by Android mobile application and Back-End server logic. Both of components were designed, tested and implemented. Designed game-environment received a name "DTU GoblinsNGold and has been launched. It is made available publicly worldwide through Google Play market. All of these aspects and milestones are described in details inside practical part of this thesis. During game-environment testing valuable data was received that described all aspects of functionality of implemented system together with behavioral patterns of players. These results of deployment together with conclusions are presented in later sections."

Abstract: "This paper presents data analysis from a course on Software Engineeri ng in an effort to identify metric s and techniques that would allow instructor to act proactively and identify patterns of low engagement and inefficient peer collaboration . Over the last two terms, 106 students in their second year of studies formed 20 groups and worked collaboratively to develop video games. Throughout the lab, students have to use a variety of tools for managing and developing their projects, such as software version control , static analysis tools , wikis, mailing lists, etc . The students are also supported by weekly meet ings with teaching assistants and instructors regarding group progress, code quality, and management issues. Through these meeting s and their interactions with the software tools, students leave a detailed trace of data related to their individual engageme nt and their collaboration behavior in their groups . The paper provides discussion on the different source of data that can be monitored , and present preliminary results on how the s e data can be used to analyze students' activity."

" Persuasive technology with game mechanics can educate and motivate people to adopt energy efficient lifestyles. "

from the introduction: "Collision avoidance and navigation among virtual agents is an important component of modern video games. Recent de- velopments in commodity hardware, in particular the utiliza- tion of multi-core and many-core architectures in personal computers and consoles are allowing large numbers of vir- tual agents to be incorporated into game levels in increasing numbers and with increasing fidelity. As a result, there is a need for efficient techniques to automatically generate real- istic behaviors for such groups of virtual agents"

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."

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."

Abstract: "In 2010, the authors (Jacobs, a game design professor, Sugarman, a pediatrician, and Rice, a psychotherapist ) started meeting to brainstorm design and play concepts for a therapeutic, physiologically-controlled videogame intended for use by people diagnosed with anxiety and/or autism spectrum disorder (ASD). The goal was to combine cognitive behavioral therapy (CBT), narrative therapy (NT) and biofeedback supported psychophysiological selfregulation (PSR) into a game that would engage adolescents and provide hard data on a player's physical and emotional states during a therapy session. The game concept that emerged is "MindGamersTM in School" (MG), a therapeutic game prototype being developed and tested across two 6-month sessions by the authors and two teams of undergraduate game design and development students at the Rochester Institute of Technology. Pursuing the design required half the team to learn principles, terms and methods of strength-based, client-centered psychotherapy and their application to psychophysiological selfregulation and biofeedback theory and practice. The other half of the team needed to engage in understanding the current state of role-playing videogames, avatar creation systems and game design/development processes. This paper will describe the current game prototype and then focus on MG's design and development process by looking at how the initial design period brought the game design to its current state and how it has continued to influence the production process."
