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."

Abstract: "For over 40 years, researchers investigated utilizing video games for education. Some of that research focused on the type of pedagogical content to embed in a game and how to integrate it, while others emphasized how to preserve the inherent intrinsic motivation in games. One of the many factors that could affect motivation and learning in video games is the different intrapersonal elements and attributes of games. In order to test those attributes' effect on motivation and learning we need to be able to define them and clearly establish a method for measuring them. The object of this study is to establish a framework for measuring three of these attributes, Challenge, Control and Goals, based on user perception. This framework is an initial step to establish a clear metric for measuring those attributes in five different game genres: First-Person Shooter, Racing, RPG, Arcade and Sports."

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: "Identifying and measuring a musical talent is not a simple task that could be performed by computers. In addition to the technical challenges, it also involves social, emotional and cultural issues. This problem is aggravated when the task needs to be performed taking as input the huge amount of music content available on the Internet today. In this paper we report work in progress on a social interactive Game with a Purpose using fun as a key motivational factor to assist in recruitment and measurement of musical talent. "

Abstract: "Intelligent Tutoring Systems (ITSs) have begun to develop hybrid systems that balance the learning benefits of ITSs with the motivational benefits of games. iSTART-ME (Motivationally Enhanced) is a new game-based learning environment developed on top of an existing ITS for reading comprehension (iSTART). In an 11 session labbased study, 40 high school students interacted with the full iSTART-ME system and completed comprehension measures at multiple time points (pretest, posttest, retention, and transfer). The current work examined students' comprehension outcomes and how they were related to performance within three integrated practice methods: Coached Practice (non-game), Showdown (game-based), and Map Conquest (game-based). Results indicate that performance within the game-based practice environments was positively related to comprehension outcomes, whereas performance within the non-game environment had no relation to subsequent comprehension measures."

From the abstract: "Our goal is to create a better understanding on how to design encounters that affect interest levels in linear FPS games. Specifically, how exactly a player's interest levels can be raised intentionally. To accomplish this, we developed a method for measuring and comparing player interest levels based on electroencephalogram (EEG) data measured using a "Neurosky Mindset" unit, which is a commercially available EEG device. We measured player EEG data for the first 4 levels of the FPS game "Call of Duty: Modern Warfare 2" and calculated player interest levels for the entire length of gameplay. By referring to recorded gameplay videos, we were able to associate each increase in interest levels for each player to a specific point in game. From this data, we found and isolated points in each level where most players showed a rise in interest levels, and discovered that certain patterns existed between these situations. These findings led to another study where we further analyzed these situations and found out what factors caused most players to show a rise in interest levels. We were able to divide these factors into 6 different categories called Triggers: "Anticipation", "Concentration", "Surprise", "Frustration", "Overwhelm" and "Fear". As these triggers represent mutually exclusive elements that affect a player's interest levels, we found that in most situations where many test subjects showed a rise in interest levels, more than one trigger is present, a phenomenon we call Stacking. While our study is still ongoing, we believe that by using these triggers as guidelines, game designers will be able to intentionally plan and control the player's interest level for FPS games with a certain level of guarantee"

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: "In this thesis we present the development of this mobile multi-platform serious game intended to teach the basic information about asthma to teenagers and young adults. We review the design of the game and the mobile technologies used to create the game. We present conclusions based on observations made while interviewees played the game, and detail the changes made to the game based on these observations. Each interviewee also provided feedback on the game, and completed several assessments to measure their knowledge of asthma before and after playing the game. We review the knowledge each interviewee gained from the interaction with the game, and draw and present conclusions based on the background each subject comes from"

From the abstract: "This study presents the defining usability quality metric for game prototype using software attributes by referring to ISO Standards 9126 - 3: Software Engineering - Product Quality, with the adaptation for the quality as surance and measurement during game p rototyping period. In order to be fully utilized and optimized the effectiveness of the proposed quality metric, it is best to define the development process environment and its application simultaneously."

"07/2012; In proceeding of: The 11th International Conference on Software Engineering Research and Practice (SERP 2012), At Las Vegas, USA ABSTRACT Usability is considered a relevant quality factor in video games. However, usability evaluations are usually performed too late in the game development lifecycle. We present a usability evaluation strategy that can be used in early stages of model-driven video game development approaches. The usability evaluation is based on a Video Game Usability Model, which extends the usability characteristic of the ISO/IEC 25010 (SQuaRE) standard by incorporating measurable attributes and measures related to the video game domain. The traceability established between the models that are produced in a modeldriven development process and the corresponding source code allows performing usability evaluations on these models, facilitating the early detection/correction of usability problems that may appear in the final video game application. To show the feasibility of this approach, we have performed an early usability evaluation of a video game for the XBOX360 platform."

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."

"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: "Mobile games - in particular, games played on smartphones and tablet computers - are becoming increasingly popular. Yet, there has been little research into whether players can experience immersion while playing mobile games. As the potential for immersive mobile games would be of interest to game developers, researchers and players, it is proposed to measure mobile immersion by comparing Osmos, a multi-platform ambient video game, on three differentsized devices - a smart phone, a tablet and a desktop computer."

Abstract: "Our study was carried out in order to improve our understanding of the relationship between 3D audio and video, and user experience in video games. In order to determine the best way to attempt to measure these effects, we researched several methods of 3D video and 3D audio delivery. We decided to use two different games to gauge the effectiveness of 3D video, Mario Kart 7 and Crysis 2. Due to a small sample size, we were unable to conclude strongly in either way about many of the factors we believed that 3 D video and audio would effect, but were able to see an increase in enjoyment and perceived ability from our surveys."

Abstract: "The rich interaction space of man y educational games presents a challenge for designers and researchers who strive to help players achieve specific learning outcomes. Giving players a large amount of freedom over how they perform a complex game task makes it difficult to anticipate what t hey will do. In order to ad dress this issue designers must ask : what are students do ing in my game? And does it embody what I intended them to learn? To answer these questions, designers need methods to expose the details of student play. We describe our a pproach for automatic extract ion of conceptu al features from logs of student play sessions within an open educational game utilizing a two - dimensional context - free grammar. We demonstrate how these features can be used to clu s- ter student solutions in the e ducational game RumbleBlocks . U s- ing these clusters , we explore the range of solutions and measure how many students use the designers' envisioned solution . Equipped with this information, designers and researchers can focus redesign efforts to areas in the game where discrepancies exist between the designer s' intention s and player experience s."

Abstract: "Serious Games are increasingly used as a training and educational tool. Fire keeps claiming a high number of victims. Some authors allege failures during the evacuation process as the main cause that contributes for that number. Fire drills are used to train buildings' occupants for emergency situations. However, fire drills' participants often have prior knowledge of their schedule and as result they are not as focused as they should. Moreover, fire drills require the mobilization of some resources, leading to financial costs. Performing a fire drill will always affect the normal functioning of the place where they take place; for this reason, sometimes they are not performed at all. In some special locations, like hospitals, fire drills are unsuitable. Emergency planning is crucial to prevent and minimize damage and victims. Albeit the improvement on safety measures, many occupants and employers in this type of buildings still lack adequate knowledge and training on how to behave in such hazardous situations. EVA is presented as a possible solution, which is based on the concept of Serious Game that can be used as a training tool for healthcare professionals. A preliminary prototype was developed. A sample of 20 subjects was selected to test it giving promising results. Results also showed that users who had training in fire prevention appear to perform better in the course. Moreover, participants who regularly play computer games overcame easily the game challenges. Further research and development are still to be explored, which are discussed in the concluding part of this paper."

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: "This paper proposes a new framework for automated analysis of game-play metrics for aiding game designers in nding out the critical aspects of the game caused by factors like design modications, change in playing style, etc. The core of the algorithm measures similarity between spatial distribution of user generated in-game events and automatically ranks them in order of importance. The feasibility of the method is demonstrated on a data set collected from a modern, multiplayer First Person Shooter, together with application examples of its use. The proposed framework can be used to accompany traditional testing tools and make the game design process more efficient."
