Abstract :"Quality of experience (QoE) is a measure of the customer's experience with a service. In an online gaming scenario, players expect the experience to be realistic, continuous and precise. It is important to know not just the end user's experience but also the probable cause of the experience, good or bad. Understanding the cause is essential for improving the game design via a feedback loop, which in turn con- tributes towards game longevity. We begin by focussing on two broad categories of the QoE measurement tech- niques for gaming scenario, subjective and objective measurement. We then study two frameworks, One-Click[4] and Perceptual View Inconsistency[5] from the perspec- tive of the scenarios in which they can be applied, their ability and more importantly, their inability to measure certain aspects of end user experience, and the diculties encountered while applying these techniques. Subsequently, we try to propose a sim- ple scheme in which both of these techniques can be used to complement each other in a real life scenario, and get the best out of both."

"For millennia, humans have participated in rituals in order to experience meaning and purpose in life. With the rise of digital games as a form of media, designers are increasing seeking to use games to provide meaningful experiences - the kind of experiences provided by rituals. This project, Farosia, explores the mechanisms by which rituals convey meaning, and presents a detailed framework for how to incorporate ritual into interactive experience design. The project consists of several small game prototypes, each intended to emphasis different aspects of ritual. By developing and playtesting these prototypes, we were able to determine how to implement these ritual modes within digital experiences, and how to use them to create a more meaningful experience to the user."

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: "A recent trend within computational intelligence and games research is to investigate how to affect video game players' in-game experience by designing and/or modifying aspects of game content. Analysing the relationship between game content, player behaviour and self-reported affective states constitutes an important step towards understanding game experience and constructing effective game adaptation mechanisms. This papers reports on further refinement of a method to understand this relationship by analysing data collected from players, building models that predict player experience and analysing what features of game and player data predict player affect best. We analyse data from players playing 780 pairs of short game sessions of the platform game Super Mario Bros, investigate the impact of the session size and what part of the level that has the major affect on player experience. Several types of features are explored, including item frequencies and patterns extracted through frequent sequence mining."

Abstract: "Cloud gaming now makes any computer game playable on a thin client without the previous worries and frustrations about the hardware requirements. It frees players from the need to frequently upgrade their computers as they can now play games that are hosted on remote servers with a broadband Internet connection and a thin client. However, cloud games are intrinsically more susceptible to latency than online games because game graphics are rendered on cloud servers and thin clients do not possess game state information that is required by delay compensation techniques. In this paper, we investigate how the response latency in cloud gaming would affect users' experience and how the impact of latency on players' experience varies among different games. We show that not all games are equally friendly to cloud gaming. That is, the same degree of latency may have very different impacts on a game's quality of experience depending on the game's real-time strictness. We thus develop a model that can predict a game's real-time strictness based on the rate of players' inputs and the game screen dynamics. The model can be used to simultaneously enhance players' gaming and optimize the operation cost of data centers."

"In cross-functional teams, team performance depends on how skillfully function managers carry out the cross-function coordination of team members' complementary expertise and activities. In this paper, we argue (i) that function managers' coordination skills develop in part through the coordination experience gained from interacting with managers from other function, (ii) that coordination experience has general and firm-specific dimensions, and (iii) that coordination experience leads to better team performance. Using data on development teams in the electronic games industry, we show that coordination experience and its general and firm-specific components have a positive impact on the commercial success of electronic games, and that this effect is robust to tests for omitted variables and reverse causality. Our results have implications for the theory of learning and coordination in teams and for the practice of team design in project-based organizations."

Abstract: "Cinematography is a key aspect in the development of mod- ern computer games. The quality of the visuals depends, not only on the accuracy of the rendering, but on the way that the scene is presented to the player. Which element should be included in the frame, from which point of view and in which positions are all aspects that have been widely stud- ied in classical cinematography. However, it is still unclear how the principles developed for the lm medium are ap- plicable to an interactive medium such as computer games. This article presents a study, which explores the interplay between cinematography and player experience. The results of the experiment demonstrate the existence of an impact of the cinematographic behaviour of camera on both player's aect and her in-game behaviour. Furthermore, this impact is dependent on the game mechanics highlighting once more the dierence between classic cinematography and game cin- ematography"

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."

To be published in May 2013, excepts in Google Books. "From the text adventures of Zork, to the arcade game of Pac-Man, to the corridors of Doom, and on to the city streets of Grand Theft Auto IV, the maze has often been used as a space to trap and confuse players in their navigation of gameworlds. However, the maze as a construction on the landscape has a long history before the invention of the videogame. By examining the change in the maze from the landscapes of open spaces and closed gardens through to the screen of the videogame, both mazes and labyrinths are discussed in terms of historical reference, alongside the author's personal experiences of walking and playing these structures. This book shows how our cultural experiences of real world maze landscapes may have changed, and how we negotiate videogame worlds along the various paths and meanings they so often create for us."

Abstract: "We present concepts of user experience (UX) research and show application areas where UX can be applied. We categorise assessment methods, and present estimation models and metrics of UX. Especially the relations between UX and bio-physiological responses, as well as observations are in the foreground." Includes a section on gamification and game experience.

Abstract: "The collaborative nature of many modern multiplayer games raises a lot of questions in cooperative game design. We address one of them in this paper by analyzing cooperative game patterns in remote gameplay in order to define benefits and drawbacks for each one. With the help of a user experiment, we analyzed player experience in a set of existing cooperative patterns for games played remotely without communication. By comparing patterns, supporting closely- and looselycoupled collaboration, we discovered that the first type provided a more enjoyable experience but introduced additional challenges in case of a lack of communication. By analyzing patterns for both closely- and loosely-coupled interaction, we determined the most beneficial pattern within each type. We concluded with the results of a pattern comparison in colocated and remote setups."

"Problem-based learning is a pedagogical approach which started in early 1970s. It is well developed and established until now. Aalborg University in Denmark is one of pioneering world universities in PBL and has accumulated a huge experience in PBL for many different study lines. One of them is Medialogy education, which was established in 2002. This paper presents transfer of experiences from Medialogy education in Denmark to Game development education in Serbia - a new (2 years old) study line successfully developed in the country where game development companies hardly exist, but a need for newly educated programmers is evident."

From the abstract: "we present an experience framework in order to show the effect of gamification on consumers' experiences that is illustrated through four extended examples. We conclude this article with a few implications for future research into, as well as practical application for the successful gamification of consumer experiences. But first, we discuss what gamification is and what it is not."

"this book is full of in-depth close readings of video games that parse out the various meanings to be found in the experience of playing a game. Contributors analyze sequences in a game in detail in order to illustrate and interpret how the various components of a game can come together to create fulfilling a playing experience unique to this medium.

Abstract: "Games with a strong notion of story are increasingly popular. With the increased amount of story content associated with games where player decisions significantly change the course of the game (branching games), comes an increase in the effort required to author those games. Despite the increased popularity of these kinds of games, it is unclear if a typical player is able to appreciate the rich content of these games, since any given player typically only experiences a small amount of that content. We create a non-branching game that simulates branching choices by providing players with choices followed by immediate textual feedback. We hypothesize that this game, where player decisions do not significantly change the course of the game, will maintain the player's sense of agency. Experimentation showed that in a text-based story with forced-choice points there were in most cases no significant difference in players' reported feelings of agency when they experience a branching story vs. a linear story with explicit acknowledgement of their choices."

Abstract :"This thesis deals with the analysis, design, implementation and testing of a video game prototype , which is intended for practicing lucid dreaming induction . R esearch i ndicates the potential of the video game medium in this end and the experimental game design has been the result of examining various study case s covering both video gam es and dreams , besides multiple lucid dreaming induction techniques . The design approach was more focused on creatively modif yin g existing techniques , in order to take advantage of the potential of the video game medium, than to simply copy them. This has led to establishi ng a set of formal design goals , with an emphasis on creating a game world simulating a dream, in which rehearsing can take place prior to sleep . The video game prototype is inasmuch an interactive training tool as it is an artistic video game experiment . With the aim of also tak ing the player experience into account, a set of aesthetic goals was also established , approached by the use of the MDA framework ( Hunicke , LeBlanc & Zubek, 2004) and the player involvement model - related to the concept of incorporation (Calleja, 2011)"

Abstract: "As a way to support developers , we propose the creation of specialized tools to deal with accessibility. The hypothesis defined was that it is possible to produce tools that coul d reduce the cost and effort needed to adapt games for people with special needs while achi eving a sufficient level of usability and a pleasant player exper ience . Because of the ambitious of the approach , the goal of the project is to explore if it is feasible through preliminary research . T hree experiments were set up to cover and explore different alternatives , given the diversity of player characteristics and game develop ment approaches . In these experiments we targeted t wo different platforms: a desktop game authoring tool oriented to educators , and a mobile game development framework oriented to programmers . In these experiments we used the to ols developed to produce several games that were also tested by end users . While the project focuses on disability, the ideas proposed can be generalized and applied to support optimizing game interfaces for a wide and diverse audience."

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."

Abstract: "People experience emotions when playing videogames. It can be argued that these emotions are their main reason for playing. In this paper, we investigate whether colors can be used in videogames to elicit specific emotions. We ran an experiment with a videogame in which four different colors, associated with four specific emotions, were used in four different conditions (in this case, four different rooms in the game). After each condition we measured the players' emotional responses by means of a Self-Assessment Manikin (SAM) questionnaire. Our analysis revealed that the color red evoked a highly-aroused, negative emotional response, while the color yellow evoked a positive emotional response. These results were significantly different from the emotional responses measured for other colors. Furthermore, we found that inexperienced players showed much more explicit reactions to colors than experienced players. We conclude that the use of colors is a suitable method for game designers to elicit specific emotional responses from the players, in particular from novice players."
