To address this, we present a theory of gamefulness that splits gamefulness into more specific constructs and outlines their effects in a process model.
Method: We integrate extant literature from psychology, human-computer interaction, and other fields to define gameful design, systems, and experiences. Most critically, we argue that gameful experience is the core focal construct of this theory and define it as an interactive state occurring when a person perceives non-trivial achievable goals created externally, is motivated to pursue them under an arbitrary set of behavioral rules, and evaluates that motivation as voluntary.
Results: We present six resulting propositions: (1) gameful systems lead to gameful experiences, (2) gameful systems impact psychological characteristics, (3) effective gameful design leads to a gameful system, (4) gameful systems lead to behavioral change, (5) behavioral change causes the distal outcomes gamification designers target, and (6) individual differences moderate the effectiveness of gameful systems.
Conclusion: Gameful experience theory provides researchers with a unified foundation to study gamification from any social scientific lens.},

Empirical Validation of the Gamification User Types Hexad Scale in English and Spanish
@article{Tondello2018e,
abstract = {Gamification, the use of game elements in non-game systems, is now established as a relevant research field in human-computer interaction (HCI). Several empirical studies have shown that gameful interventions can increase engagement and generate desired behavioural outcomes in HCI applications.

The Gamification User Types Hexad scale allows us to parse different user motivations in participants‘ interactions with gameful applications, which are measured using a self-report questionnaire. Each user type represents a style of interaction with gameful applications, for example, if the interactions are more focused on achievements, socialization, or rewards. Thus, by scoring an individual in each one of the user types of the Hexad model, we can establish a profile of user preferences for gameful interactions. However, we still lack a substantial empirical validation of this scale. Therefore, we set out to validate the factor structure of the scale, in both English and Spanish, by conducting three studies, which also investigated the distribution of the Hexad‘s user types in the sample. Our findings support the structural validity of the scale, as well as suggesting opportunities for improvement.

}Despite the emergence of many gameful design methodologies in the literature, there is a lack of methods to evaluate the resulting designs. Gameful design techniques aim to increase the user’s motivation to interact with a software, but there are presently no accepted guidelines on how to find out if this goal was achieved during the design phase of a project. This paper presents the Gameful Design Heuristics, a novel set of guidelines that facilitate a heuristic evaluation of gameful software, with a focus on the software’s potential to afford intrinsic and extrinsic motivation for the user. First, we reviewed several gameful design methods to identify the most frequently employed dimensions of motivational affordances. Then, we devised a set of 28 gamification heuristics that can be used to rapidly evaluate a gameful system. Finally, we conducted a summative empirical evaluation study with five user experience professionals, which demonstrated that our heuristics can help the evaluators find more motivational issues in interactive systems than they would without the heuristics. The suggested method fulfills the need for evaluation tools specific to gameful design, which could help evaluators assess the potential user experience of a gameful application in the early phases of a project.
Older Adults’ Physical Activity and Exergames: A Systematic Review

“I don't fit into a single type”: A Trait Model and Scale of Game Playing Preferences

year = {2019}
}Player typology models classify different player motivations and behaviours. These models are necessary to design personalized games or to target specific audiences. However, many models lack validation and standard measurement instruments. Additionally, they rely on type theories, which split players into separate categories. Yet, personality research has lately favoured trait theories, which recognize that people's preferences are composed of a sum of different characteristics. Given these shortcomings of existing models, we developed a player traits model built on a detailed review and synthesis of the extant literature, which introduces five player traits: aesthetic orientation, narrative orientation, goal orientation, social orientation, and challenge orientation. Furthermore, we created and validated a 25-item measurement scale for the five player traits. This scale outputs a player profile, which describes participants' preferences for different game elements and game playing styles. Finally, we demonstrate that this is the first validated player preferences model and how it serves as an actionable tool for personalized game design.

Effect of personalized gameful design on student engagement

}In distributed multiplayer games, it can be difficult to communicate strategic information for planning game moves and player interactions. Often, players spend extra time communicating, reducing their engagement in the game. Visual annotations in game maps and in the gameworld can address this problem and result in more efficient player communication. We studied the impact of real-time feedback on planning annotations, specifically two different annotation types, in a custom-built, third-person, multiplayer game and analyzed their effects on player performance, experience, workload, and annotation use. We found that annotations helped engage players in collaborative planning, which reduced frustration, and shortened goal completion times. Based on these findings, we discuss how annotating in virtual game spaces enables collaborative planning and improves team performance.

}When player skill levels are not matched, games provide an unsatisfying player experience. Player balancing is used across many digital game genres to address this, but has not been studied for co-located augmented reality (AR) tabletop games, where using boosts and handicaps can adjust for different player skill levels. In the setting of an AR table football game, we studied the importance of game balancing being triggered by the game system or the players, and whether player skill should be required to trigger game balancing. We implemented projected icons to prominently display game balancing mechanics in the AR table football game. In a within-subjects study (N=24), we found players prefer skill-based control over game balancing and that different triggers are perceived as having different fairness. Further, the study showed that even game balancing that is perceived as unfair can provide enjoyable game experiences. Based on our findings, we provide suggestions for player balancing in AR tabletop games.
Online-only friends, real-life friends or strangers? Differential associations with passion and social capital in video game play

}The present study tests a recently proposed model in which social video game play supports wellbeing by contributing to a harmonious type of engagement with the game. Players (N = 2030) of the online-only multiplayer first-person shooter game, Destiny, reported the frequency they played with real-life friends, online-only friends and strangers, their type of engagement with the game – measured as harmonious and obsessive passion, and completed a wellbeing measure of social capital. Telemetry data also recorded their total time playing over the duration of the study. A structural equation model supported the prediction that harmonious – but not obsessive – passion would mediate the positive association between playing with others and social capital. The findings also supported a supplementary hypothesis that the three types of social relationships would be differentially associated with two forms of social capital – bridging versus bonding – as a function of the closeness of social ties. Real-life friends was positively associated with bonding, strangers with bridging, and online-only friends with both. Overall, these results emphasise that social interactions in (and around) online multiplayer video games are effective for building social capital, and do so by ensuring game play is in harmony with other goals and values.

}Persuasive gameful systems are effective tools for motivating behaviour change. Research has shown that tailoring these systems to individuals can increase their efficacy; however, there is little knowledge on how to personalize them. We conducted a large-scale study of 543 participants to investigate how different gamification user types responded to ten persuasive strategies depicted in storyboards representing persuasive gameful health systems. Our results reveal that people’s gamification user types play significant roles in the perceived persuasiveness of different strategies. People scoring high in the ‘player’ user type tend to be motivated by competition, comparison, cooperation, and reward while ‘disruptors’ are likely to be demotivated by punishment, goal-setting, simulation, and self-monitoring. ‘Socialisers’ could be motivated using any of the strategies; they are the most responsive to persuasion overall. Finally, we contribute to CHI research and practice by offering design guidelines for tailoring persuasive gameful systems to each gamification user type.

Towards Customizing Gameful Systems by Gameful Design Elements

}Recently, several researchers have suggested that personalized game-ful systems can be more effective than generic approaches. However, there is still scarce empirical evidence that the suggested factors for personalization, such as gender, age, user types, and personality traits, will be effective in im-proving user engagement and performance for personalized gameful systems. In this work-in-progress, we present a research plan for empirical evaluation of a customizable gameful system. Upon completion of this study, we expect to pro-vide empirical evidence that the participants’ selection of gameful design ele-ments in a practical application will correspond to the theorized relationships suggested by prior survey-based research, and that the system can suggest the gameful design elements that users are more likely to enjoy. The results of this research will provide an actionable path for gamification designers to imple-ment personalized gameful systems and for researchers to develop recommen-dation algorithms for gamification.
Towards a Trait Model of Video Game Preferences

}Sound and virtual reality (VR) are two important output modalities for creating an immersive player experience (PX). While prior research suggests that sounds might contribute to a more immersive experience in games played on screens and mobile displays, there is not yet evidence of these effects of sound on PX in VR. To address this, we conducted a within-subjects experiment using a commercial horror-adventure game to study the effects of a VR and monitor-display version of the same game on PX. Subsequently, we explored, in a between-subjects study, the effects of audio dimensionality on PX in VR. Results indicate that audio has a more implicit influence on PX in VR because of the impact of the overall sensory experience and that audio dimensionality in VR may not be a significant factor contributing to PX. Based on our findings and observations, we provide five design guidelines for VR games.

A Framework and Taxonomy of Videogame Playing Preferences

However, current models suggested by the extant literature are generally based on classifying abstract gaming motivations or player archetypes.

To address this issue, we propose a conceptual framework of player preferences based on two dimensions: game elements and game playing styles. To investigate these two concepts, we conducted an exploratory empirical investigation of player preferences, which allowed us to create a taxonomy of nine groups of game elements and five groups of game playing styles. These two concepts are foundational to games, which means that our model can be used by designers to create games that are tailored to their target audience. In addition, we demonstrate that there are significant effects of gender and age on participants' preferences and discuss the implications of these findings.},

Elements of Gameful Design Emerging from User Preferences

}Why do we care if our teammates are not human? This study seeks to uncover whether or not the perception of other players as human or artificial entities can influence player experience. We use both deception and a between-participants blind study design to reduce bias in our experiment. Our qualitative results show that people do care about the perceived nature of other players, even though they are not always able to correctly identify them as human or as non-player character teammates. Interview data suggest believing that one is playing with other humans can positively affect a player’s subjective experience. Furthermore, our qualitative results indicate that players view their non-player character teammates as humanized entities, but adopt a neo-feudalistic (i.e., an unequal rights) view of them. Based on our results, we establish game design guidelines for non-player character teammates leading to stronger, emotional human-computer relationships in video games.

Testing Incremental Difficulty Design in Platformer Games
@inproceedings{Wehbe2017,
abstract = {Designing difficulty levels in platformer games is a challenge for game designers. It is important because design decisions that affect difficulty also directly affect player experience. Consequently, design strategies for balancing game difficulty are discussed by both academics and game designers. In this paper, we study how manipulating the following design decisions, commonly found in platformers, moderates difficulty: Scroll Speed, Target Size, Jump Task Complexity, and Perspective. Results for Scroll Speed and Target Size indicate that errors increase as speed increases and platform size decreases. However, results for jump task complexity demonstrate a separation of errors from task complexity. Specifically, while double-jump tasks are harder than single-jump tasks, triple-jump tasks appear to be as difficult as double-jump tasks. Additionally, the study demonstrates how changes in perspective affect the errors made by players in gameplay.

}Designing difficulty levels in platformer games is a challenge for game designers. It is important because design decisions that affect difficulty also directly affect player experience. Consequently, design strategies for balancing game difficulty are discussed by both academics and game designers. In this paper, we study how manipulating the following design decisions, commonly found in platformers, moderates difficulty: Scroll Speed, Target Size, Jump Task Complexity, and Perspective. Results for Scroll Speed and Target Size indicate that errors increase as speed increases and platform size decreases. However, results for jump task complexity demonstrate a separation of errors from task complexity. Specifically, while double-jump tasks are harder than single-jump tasks, triple-jump tasks appear to be as difficult as double-jump tasks. Additionally, the study demonstrates how changes in perspective affect the errors made by players in gameplay. The study results are applicable both to automatic level generation and dynamic difficulty adjustment in platformer games.
The Impact of Health-Related User Interface Sounds on Player Experience

abstract = {Background. Understanding how sound functions on informational and emotional levels within video games is critical to understanding player experience of games.

To address this research gap in user interface sounds, we present two studies: The first study examines the impact of the presence or absence of player-health sounds on player experience. The second study explores the impact of the types of sound used to indicate player health. We use mixed methods with qualitative and physiological measures. Results. Our results reveal that despite the presence of visual cues, sound is still important to game design for conveying health-related information and that the type of sound affects player experience.},

Research has shown that tailoring these systems can increase their efficacy.

Our results reveal that people's personality traits play a significant role in the perceived persuasiveness of different strategies.

All about that Base: Differing Player Experiences in Video Game Genres and the Unique Case of MOBA Games
@inproceedings{Johnson2015,
Abstract = {Video games provide unique interactive player experiences (PX) often categorised into different genres. Prior research has looked at different game genres, but rarely through a PX lens. Especially, PX in the emerging area of massive online battle arena (MOBA) games is not well understood by researchers in the field. We address this knowledge gap by presenting a PX study of different game genres, which we followed up with a second semi-structured interview study about PX in MOBA games. Among the results of our analyses are that games that are likely played with other players, such as MOBA games, stimulate less immersion and presence for players. Additionally, while challenge and frustration are significantly higher in this genre, players get a sense of satisfaction from teamwork, competition and mastery of complex gameplay interactions. Our study is the first to contribute a comprehensive insight into key motivators of MOBA players and how PX in this genre is different from other genres.},

CHI PLAYGUE: A Networking Game of Emergent Sociality
@inproceedings{Tondello2015a,
Abstract = {Modern professional networking is heavily reliant on social media. In recognition of this trend, we present CHI PLAYGUE, a conference game designed to facilitate interaction among strangers and encourage social networking to create a community. The game facilitates the emergence of social dynamics related to trust, allegiance, betrayal, selective interaction, and long- term strategic cooperation. By providing a platform for large-scale playful interaction, we will create an experience that will foster the development of mutually beneficial personal and professional relationships among players.},

Personalization in Serious and Persuasive Games and Gamified Interactions

Fuzzy Affective Player Models: A Physiology-Based Hierarchical Clustering Method
@inproceedings{nogueira2014fuzzy,
Abstract = {Current approaches to game design improvements rely on time-consuming gameplay testing processes, which rely on highly subjective feedback from a target audience. In this paper, we propose a generalizable approach for building predictive models of players' emotional reactions across different games and game genres, as well as other forms of digital stimuli. Our input agnostic approach relies on the following steps: (a) collecting players' physiologically-inferred emotional states during actual gameplay sessions, (b) extrapolating the causal relations between changes in players' emotional states and recorded game events, and (c) building hierarchical cluster models of players' emotional reactions that can later be used to infer individual player models via fuzzy cluster membership vectors. We expect this work to benefit game designers by accelerating the affective play-testing process through the offline simulation of players' reactions to game design adaptations, as well as to contribute towards individually-tailored affective gaming.},

Introducing the Biometric Storyboards Tool for Games User Research
@inproceedings{mirza2014introducing,
Abstract = {Evaluating and communicating affective user experience in games is an important component of the growing field of games user research (GUR). An important goal for the game industry and researchers alike is the successful unification of physiological measurements and player experience reports to generate meaningful insights, which is challenging due to the varying natures of the data. In this paper, we present a tool that facilitates GUR with a method called Biometric Storyboards (BioSt). The tool allows GUR professionals to visualize relationships between changes in a player's physiological state, a player's self-reported experience, and in-game events.

Physiological Acrophobia Evaluation Through In Vivo Exposure in a VR CAVE
@inproceedings{costa2014physiological,
Abstract = {Acrophobia (i.e., the fear of heights) is commonly treated using Virtual Reality (VR) applications. Patients that suffer from this clinical condition can experience extreme levels of anxiety, stress, and discomfort, even at relatively low heights. VR computer-assisted virtual environments (CAVEs) have been found to be highly immersive and successful in the treatment of acrophobia. The general method of evaluating therapy progress is through self-reported questionnaire measures. However, these are subject to participant bias. Physiological measures, on the other hand, could provide a more objective way of assessing acrophobia. To our knowledge, psychophysiological measures are not commonly used in the evaluation of acrophobes and their therapy progress within CAVEs. Thus, we present a CAVE application for acrophobia treatment, which includes a physiological feedback mechanism to assess patient progress. It also permits patient movement to facilitate increased presence and immersion. In this application, players sequentially gain access to increasing heights as they successfully progress through lesser heights, as assessed through the evaluation of their physiological responses to VR stimuli.},

Social Player Analytics in a Facebook Health Game
@inproceedings{Nacke:2014:SPA:2729485.2729512,
Abstract = {Social health games can drive healthy behaviour. To track social behaviour change in social network games (SNGs), gameplay metrics should quantify socially-engaging gameplay behaviour based on player interactions. We developed social player metrics in a quantitative study of player behaviour in a social health game called Healthseeker (developed by Ayogo Health Inc.). This Facebook game targets people with diabetes to help them manage health goals in real life. Our metrics identify which game mechanics led to more gameplay success, connectedness and virality. We also identified how the behaviour of successful players differs from unsuccessful players in the game. Our results support that game mechanics aiming at social interactions can motivate players to solve more missions, to fulfill more healthy goals and to play the game longer. We conclude that having a well-connected social network can improve player success in solving game missions.},

Unified Visualization of Quantitative and Qualitative Playtesting Data

Visualization techniques can facilitate the understanding of relationships among these data sets. Although various visualization techniques have already been introduced in GUR, most of these techniques only focus on displaying large amounts of data captured directly via telemetry without integrating qualitative or contextual data on players' emotional experience.

A Hybrid Approach at Emotional State Detection: Merging Theoretical Models of Emotion with Data-Driven Statistical Classifiers
@inproceedings{nogueira2013hybrid,
Abstract = {With the rising popularity of affective computing techniques, there have been several advances in the field of emotion recognition systems. However, despite the several advances in the field, these systems still face scenario adaptability and practical implementation issues. In light of these issues, we developed a nonspecific method for emotional state classification in interactive environments. The proposed method employs a two-layer classification process to detect Arousal and Valence (the emotion's hedonic component), based on four psychophysiological metrics: Skin Conductance, Heart Rate and Electromyography measured at the corrugator supercilii and zygomaticus major muscles. The first classification layer applies multiple regression models to correctly scale the aforementioned metrics across participants and experimental conditions, while also correlating them to the Arousal or Valence dimensions. The second layer then explores several machine learning techniques to merge the regression outputs into one final rating. The obtained results indicate we are able to classify Arousal and Valence independently from participant and experimental conditions with satisfactory accuracy (97\% for Arousal and 91\% for Valence).},

A Regression-Based Method for Lightweight Emotional State Detection in Interactive Environments
@article{nogueira2013regression,
Abstract = {With the popularity increase in affective computing techniques the number of emotion detection and recognition systems has risen considerably. However, despite their steady accuracy improvement, they are yet faced with application domain transferability and practical implementation issues. In this paper, we present a novel methodology for modelling individuals' emotional states in multimedia interactive environments, while addressing the aforemen- tioned transferability and practical implementation issues. Our method relies on a two-layer classification process to classify Arousal and Valence based on four distinct physiological sensor inputs. The first classification layer uses several regression models to normalize each of the sensor inputs across participants and experimental conditions, while also correlating each input to either Arousal or Valence. The second classification layer then employs decision trees to merge the various regression outputs into one optimal Arousal/Valence classification. The presented method not only exhibits convincing accuracy ratings -- 89\% for Arousal and 84\% for Valence - but also presents an adaptable and practical ap- proach at emotional state detection in interactive environment experiences.},

Assessing User Preference of Video Game Controller Button Settings
@inproceedings{ellick2013assessing,
Abstract = {Only very few studies exist linking preference in controller usage to physiological effects and user experience (UX). While many games already feature different controller layouts, there is a lack of research on whether giving control to participants over their button choices affects their UX in the game. In our study, participants were given two predetermined button configurations for playing FIFA 12. Their preferences were assessed through electroencephalography (EEG) and a Game Experience Questionnaire (GEQ). Our results show no significant difference in EEG intensity between participants using their preferred or non-preferred button settings. Preference also appears to have no significant effect on subjective feelings assessed by the GEQ. We have identified three distinct factors that may have potentially compromised this study.

Contextual Influences on Mobile Player Experience--A Game User Experience Model
@article{engl2012contextual,
Abstract = {In this paper we are discussing a new model of mobile gameplay experience with a special focus on contextual influences of play in ubiquitous environments. The model was developed based on prior general gameplay models which were extended and refined based on the results and personal experiences taken from several evaluative user field studies with mobile games. The experimental results point to two different playing contexts: home and mobile, which were evaluated with a gameplay experience questionnaire (GEQ). The GEQ showed significant difference in negative affect and immersion between mobile and home setting, which are moderated by several influencing contextual factors. This leads us to propose a contextual gameplay experience model that accounts for spatial, temporal, social, cultural, and psychological influences in an external context. The implications of the contextual gameplay model are discussed in light of future research.},

Url = {https://hcigames.com/download/contextual-influences-on-mobile-player-experience-a-game-user-experience-model},
Volume = {4},
Year = {2013},In this paper we are discussing a new model of mobile gameplay experience with a special focus on contextual influences of play in ubiquitous environments. The model was developed based on prior general gameplay models which were extended and refined based on the results and personal experiences taken from several evaluative user field studies with mobile games. The experimental results point to two different playing contexts: home and mobile, which were evaluated with a gameplay experience questionnaire (GEQ). The GEQ showed significant difference in negative affect and immersion between mobile and home setting, which are moderated by several influencing contextual factors. This leads us to propose a contextual gameplay experience model that accounts for spatial, temporal, social, cultural, and psychological influences in an external context. The implications of the contextual gameplay model are discussed in light of future research.
Deconstructing `Gamified' Task-Management Applications
@inproceedings{kappen2013deconstructing,
Abstract = {Many tasks---and the societal need to attend events as part of our office culture---have an overwhelming effect on our management capacity. Using gamification to make task and chore management more exciting could allow people to be more productive while they are engaged and focused on their tasks. There is currently a lack of studies on the usefulness of gamified task-management applications. We address this by taking a look at two memory-aid applications with task-based gamification: Task Hammer (TH) and Epic Win (EW). Among our findings is that TH was easier to learn to use while EW was more satisfying and motivating. Participants who felt good about an apps' reward system were also more satisfied with its use. Conventional task managers are, however, preferred for speed and efficiency. Based on our interviews, it seems that gamified task managers are not more useful than classical ones. However, there is a relation between how participants perceive game elements and how useful they find it for task management.},

Designing and Evaluating Sociability in Online Video Games
@inproceedings{christou2013designing,
Abstract = {The emergence of Online Video Games has led to new ways of socializing with friends. Nowadays a good online game is also associated with the pleasure of socializing and interaction with other players. One cannot play such a game solitarily in a meaningful sense without interacting with the other players. However, there are still no integrated ways of designing and evaluating the inherent sociability of online video games, nor are there methods or guidelines for designing and evaluating social user experiences. Designers of online video games are often left to use their intuition and experience, many times leading to design failures. This workshop aims to further the understanding of designing for sociability and evaluating such designs for online video games. The goal is to exact a framework for the design of sociability structures in online games, and identify methods of effective evaluation of those structures that are practical and can be applied in the industry. With the wide reach of online video games, the time is ripe to codify and integrate the methods that have been developed for designing and evaluating social player experiences. The results will then be turned into a methodological framework that enables online video game designers to select appropriately existing methods and tools to design and evaluate systematically the social player experience of their online computer game prototypes and products.},

EEG-Based Assessment of Video and In-Game Learning
@inproceedings{wehbe2013eeg,
Abstract = {People often learn game-related information in video games by taking turns playing and watching each other play. This type of in-game learning involves both observation and imitation of actions. However, games are also made to be learnt individually during gameplay. Our study seeks to assess which is more effective for learning: just playing a game yourself or watching somebody play it first. We compare two gameplay situations: playing a digital game before watching a game-play video and playing a digital game after watching a gameplay video. Using a between-participants design, to measure learning effectiveness we recorded Mu rhythms, which are indirectly linked to mirror neuron activation during imitation learning. We also analyze hemispheric frontal alpha asymmetry. Our results indicate that presentation order of the video game matters and players are more aroused when watching a gameplay video before playing.},

Guided Emotional State Regulation: Understanding and Shaping Players' Affective Experiences in Digital Games
@inproceedings{nogueira2013guided,
Abstract = {Designing adaptive games for individual emotional experi- ences is a tricky task, especially when detecting a player's emotional state in real time requires physiological sensing hardware and signal processing software. There is currently a lack of software that can identify and learn how emotional states in games are triggered. To address this problem, we developed a system capable of understanding the fundamen- tal relations between emotional responses and their eliciting events. We propose time-evolving Affective Reaction Mod- els (ARM), which learn new affective reactions and manage conflicting ones. These models are then meant to provide in- formation on how a set of predetermined game parameters (e.g., enemy and item spawning, music and lighting effects) should be adapted, to modulate the player's emotional state. In this paper, we propose and describe a framework for modulating player emotions and the main components in- volved in regulating players' affective experience. We ex- pect our technique will allow game designers to focus on defining high-level rules for generating gameplay experi- ences instead of having to create and test different content for each player type.},

How Does It Play Better? Exploring User Testing and Biometric Storyboards in Games User Research

Abstract = {Improving game design is a hard task. Few methods are available in games user research (GUR) to test formally how game designs work for players. In particular, the usefulness of user tests (UTs) for game designers has not been fully studied in the CHI community. We propose a novel GUR method called Biometric Storyboards (BioSt) and present a study demonstrating how a Classic UT and a BioSt UT both help designers create a better gameplay experience. In addition, we show that BioSt can help designers deliver significantly better visuals, more fun, and higher gameplay quality than designing without UTs and that classic UTs do not provide this significant advantage. Our interviews support the idea that BioSt provides more nuanced game design improvement. The design implication is that a game designed with the BioSt method will result in high gameplay quality.},

These sites offer tools and opportunities for social interaction, but little is known about how people really interact on these sites. To learn more about social dynamics on game sites, we analysed three months of log files from a large site to explore three themes: permanence (whether people formed a long-term association with the site); social interaction (in terms of shared activity and verbal communication); and formation of ties (whether people made contacts with others). Our analyses showed that while the site seems very social when we consider gameplay, the population was highly transient, and people talked very little. To explain these behaviours, we suggest that games and game-based activity should be considered as a legitimate form of human interaction. Our analysis provides new information and new ways of thinking about how game environments can be designed to support many kinds of sociability.},

Feedback-Based Gameplay Metrics: Measuring Player Experience via Automatic Visual Analysis
@inproceedings{marczak2012feedback,
Abstract = {Using gameplay metrics to articulate player interaction within game systems has received increased interest in game studies. The value of gameplay metrics comes from a desire to empirically validate over a decade of theorization of player experience and knowledge of games as ludic systems. Taking gameplay metrics beyond formalized user testing (i.e. with the aim of improving a product) allows researchers the freedom of examining any commercially available game without the need to have access to the game's source code. This paper offers a new methodology to obtain data on player behavior, achieved through analyzing video and audio streams. Game interface features are being analyzed automatically, which are indicative of player behavior and gameplay events. This paper outlines the development of this methodology and its application to research that seeks to understand the nature of engagement and player motivations.},

Full-Body Motion-Based Game Interaction for Older Adults
@inproceedings{gerling2012full,

Full-body motion-control games provide an opportunity for these adults to remain active and engaged; these games are not designed with age-related impairments in mind, which prevents the games from being leveraged to increase the activity levels of older adults. In this paper, we present two studies aimed at developing game design guidelines for full-body motion controls for older adults experiencing age-related changes and impairments. Our studies also demonstrate how full-body motion-control games can accommodate a variety of user abilities, have a positive effect on mood and, by extension, the emotional well-being of older adults. Based on our studies, we present seven guidelines for the design of full-body interaction in games. The guidelines are designed to foster safe physical activity among older adults, thereby increasing their quality of life.},

Our results show participants have a preference for direct physiological control in games. This has two major design implications for physiologically controlled games: (1) Direct physiological sensors should be mapped intuitively to reflect an action in the virtual world; (2) Indirect physiological input is best used as a dramatic device in games to influence features altering the game world.},

We explain how each of these player archetypes relates to older player typologies (such as Myers-Briggs), and how each archetype characterizes a specific playing style. We conducted a survey among more than 50,000 players using the BrainHex model as a personality type motivator to gather and compare demographic data to the different BrainHex archetypes.

Calibration Games : Making Calibration Tasks Enjoyable by Adding Motivating Game Elements
@inproceedings{Flatlaetal2011,
Abstract = {Interactive systems often require calibration to ensure that input and output are optimally configured. Without calibration, user performance can degrade (e.g., if an input device is not adjusted for the user's abilities), errors can increase (e.g., if color spaces are not matched), and some interactions may not be possible (e.g., use of an eye tracker). The value of calibration is often lost, however, because many calibration processes are tedious and unenjoyable, and many users avoid them altogether. To address this problem, we propose calibration games that gather calibration data in an engaging and entertaining manner. To facilitate the creation of calibration games, we present design guidelines that map common types of calibration to core tasks, and then to well-known game mechanics. To evaluate the approach, we developed three calibration games and compared them to standard procedures. Users found the game versions significantly more enjoyable than regular calibration procedures, without compromising the quality of the data. Calibration games are a novel way to motivate users to carry out calibrations, thereby improving the performance and accuracy of many human-computer systems.},

Developing a Triangulation System for Digital Game Events, Observational Video, and Psychophysiological Data to Study Emotional Responses to a Virtual Character
@article{matias2011developing,
Abstract = {Game researchers are currently lacking comprehensive data analysis tools that triangulate game events, event-related survey data, and psychophysiological data. Such a tool would allow a comprehensive analysis of player engagement in digital games. The development of this tool was motivated by an experimental psychology study that asked whether emotional reactions to congruent and incongruent emotional stimuli within an intrinsically motivated game task are the same as within the traditional experimental picture-viewing paradigm. To address the needs of our study, we used the Source SDK (Valve Corporation) for creating a system that automates event logging, video management psychophysiological data markup. The system also allowed recording of self-report measures at individual play events without interrupting the game activity.},

BdskUrl2 = {http://dx.doi.org/10.1016/j.entcom.2011.03.006}}Game researchers are currently lacking comprehensive data analysis tools that triangulate game events, event-related survey data, and psychophysiological data. Such a tool would allow a comprehensive analysis of player engagement in digital games. The development of this tool was motivated by an experimental psychology study that asked whether emotional reactions to congruent and incongruent emotional stimuli within an intrinsically motivated game task are the same as within the traditional experimental picture-viewing paradigm. To address the needs of our study, we used the Source SDK (Valve Corporation) for creating a system that automates event logging, video management psychophysiological data markup. The system also allowed recording of self-report measures at individual play events without interrupting the game activity.

From Game Design Elements to Gamefulness: Defining "Gamification"
@inproceedings{deterding2011game,
Abstract = {Recent years have seen a rapid proliferation of mass-market consumer software that takes inspiration from video games. Usually summarized as "gamification", this trend connects to a sizeable body of existing concepts and research in human-computer interaction and game studies, such as serious games, pervasive games, alternate reality games, or playful design. However, it is not clear how "gamification" relates to these, whether it denotes a novel phenomenon, and how to define it. Thus, in this paper we investigate "gamification" and the historical origins of the term in relation to precursors and similar concepts. It is suggested that "gamified" applications provide insight into novel, gameful phenomena complementary to playful phenomena. Based on our research, we propose a definition of "gamification" as the use of game design elements in non-game contexts.},

Influencing Experience: The Effects of Reading Game Reviews on Player Experience
@incollection{livingston2011influencing,
Abstract = {Game reviews are used by game developers for making business decisions and measuring the success of a title, and have been shown to affect player perception of game quality. We conducted a study where players read positive or negative reviews of a game before playing, and show that the valence of review text affected game ratings and that these differences could not be explained by mediating changes in mood. Although we show predictable changes in player experience over the course of the study (measured objectively through physiological sensors), there were no objective differences in experience depending on review valence. Our results suggest that reading reviews does not directly affect play experience, but rather is a post-play cognitive rationalization of the experience with the content of the review. Our results are important for understanding player experience and to the game industry where reviews and user forums affect a game's commercial success.},

LAIF: A Logging and Interaction Framework for Gaze-Based Interfaces in Virtual Entertainment Environments

Player Typology in Theory and Practice

Examination of psychometric typologies reveal that type theories have---except in rare cases---proven inadequate and have made way for alternative trait theories.

Statistical analysis of the results of one survey in this lineage is presented, along with a discussion of theoretical and practical ways in which the surveys and their implied typological instruments have evolved.},

Player-Game Interaction Through Affective Sound
@article{nacke2011player,
Abstract = {This chapter treats computer game playing as an affective activity, largely guided by the audio-visual aesthetics of game content (of which, here, we concentrate on the role of sound) and the pleasure of gameplay. To understand the aesthetic impact of game sound on player experience, definitions of emotions are briefly discussed and framed in the game context. This leads to an introduction of empirical methods for assessing physiological and psychological effects of play, such as the affective impact of sonic player-game interaction. The psychological methodology presented is largely based on subjective interpretation of experience, while psychophysiological methodology is based on measurable bodily changes, such as context-dependent, physiological experience. As a means to illustrate both the potential and the difficulties inherent in such methodology we discuss the results of some experiments that investigate game sound and music effects and, finally, we close with a discussion of possible research directions based on a speculative assessment of the future of player-game interaction through affective sound.},

BioS-Play: Workshop on Multiuser and Social Biosignal Adaptive Games and Playful Applications
@article{kuikkaniemi2010bios,
Abstract = {BioS-Play is a workshop targeted to explore the focused domain of biosignal adaptive games and playful application in a multiuser or social context. Using biosignal instrumentation is an established process in medical domains and experimental psychology. During recent years there have been many efforts in industry and research to develop applications, games and various kinds of interfaces which use biosignal analysis in real time. However, most of these applications are single user setups. According to our earlier work we have realized that there is great potential in developing biosignal adaptive applications for multiuser and social scenarios. The applications we have been developing have been either games or playful applications. Games have unique characteristics, which work well for biosignal augmentation. In addition, games can be used in a laboratory setup for exploring the social biosignal interaction design elements overall in a structured and efficient way. Ultimately, we believe that combination of biosignal adaptation, social and multiuser context, and playful interaction is useful for various kinds of situations and can elicit never before- seen experiences. The workshop organizers have several years of experience in researching games, psychophysiology, multiuser application development, and combination of them all. The workshop will be organized with a help of the Presemo presentation environment, which is also a biosignal, adaptive, social, and playful system. The workshop aims at creating new collaborations by facilitating networking of interested researchers and discussing research future research ventures in this domain, distributing knowledge among participants and developing a roadmap related to the future development in this field. Workshop participants are expected to show interest in developing biosignal prototypes or running experiments with experimental psychophysiological systems. In addition to game researchers and individuals with experience in analyzing and working with biosignals, we hope that also people with experience or strong interest in multiuser applications and social interaction will join the session.},

The applications we have been developing have been either games or playful applications. Games have unique characteristics, which work well for biosignal augmentation. In addition, games can be used in a laboratory setup for exploring the social biosignal interaction design elements overall in a structured and efficient way. Ultimately, we believe that combination of biosignal adaptation, social and multiuser context, and playful interaction is useful for various kinds of situations and can elicit never before- seen experiences. The workshop organizers have several years of experience in researching games, psychophysiology, multiuser application development, and combination of them all. The workshop will be organized with a help of the Presemo presentation environment, which is also a biosignal, adaptive, social, and playful system. The workshop aims at creating new collaborations by facilitating networking of interested researchers and discussing research future research ventures in this domain, distributing knowledge among participants and developing a roadmap related to the future development in this field. Workshop participants are expected to show interest in developing biosignal prototypes or running experiments with experimental psychophysiological systems. In addition to game researchers and individuals with experience in analyzing and working with biosignals, we hope that also people with experience or strong interest in multiuser applications and social interaction will join the session.

Correlation Between Heart Rate, Electrodermal Activity and Player Experience in First-Person Shooter Games
@inproceedings{Drachen2010,
Abstract = {Psychophysiological methods are becoming more popular in game research as covert and reliable measures of affective player experience, emotions, and cognition. Since player experience is not well understood, correlations between self-reports from players and psychophysiological data may provide a quantitative understanding of this experience. Measurements of electrodermal activity (EDA) and heart rate (HR) allow making inferences about player arousal (i.e., excitement) and are easy to deploy. This paper reports a case study on HR and EDA correlations with subjective gameplay experience, testing the feasibility of these measures in commercial game development contexts. Results indicate a significant correlation (p < 0.01) between psychophysiological arousal (i.e., HR, EDA) and self-reported gameplay experience. However, the covariance between psychophysiological measures and self-reports varies between the two measures. The results are consistent across three different contemporary major commercial first-person shooter (FPS) games (Prey, Doom 3, and Bioshock).},

Critic-Proofing: Robust Validation Through Data-Mining
@article{livingston2010critic,
Abstract = {Critic-proofing is a modified heuristic evaluation technique, specifically designed to provide a fine-grained, prioritized list of heuristic violations. The critic-proofing technique weights the severity of a problem based on the frequency that similar problems are found in similar games. The severity ratings are calculated using data collected from game reviews, and the severity assigned to a problem during the heuristic evaluation process. However, heuristic techniques have had limited adoption within the video game industry. One reason for this is the perceived lack of validity and robustness of game specific heuristic principles.

Electroencephalographic Assessment of Player Experience: A Pilot Study in Affective Ludology
@article{NackeSG2010,
Abstract = {Psychophysiological methods, such as electroencephalography (EEG), provide reliable high-resolution measurements of affective player experience. In this article, the authors present a psychophysiological pilot study and its initial results to solidify a research approach they call affective ludology, a research area concerned with the physiological measurement of affective responses to player-game interaction. The study investigates the impact of level design on brainwave activity measured with EEG and on player experience measured with questionnaires. The goal of the study was to investigate cognition, emotion, and player behavior from a psychological perspective. For this purpose, a methodology for assessing gameplay experience with subjective and objective measures was developed extending prior work in physiological measurements of affect in digital gameplay. The authors report the result of this pilot study, the impact of three different level design conditions (boredom, immersion, and flow) on EEG, and subjective indicators of gameplay experience. Results from the subjective gameplay experience questionnaire support the validity of our level design hypotheses. Patterns of EEG spectral power show that the immersion-level design elicits more activity in the theta band, which may support a relationship between virtual spatial navigation or exploration and theta activity. The research shows that facets of gameplay experience can be assessed with affective ludology measures, such as EEG, in which cognitive and affective patterns emerge from different level designs.},

Gameplay Experience Testing with Playability and Usability Surveys-An Experimental Pilot Study
@article{nacke2010gameplay,
Abstract = {This pilot study investigates an experimental methodology for gathering data to create correlations between experiential factors measured by a gameplay experience questionnaire and player quality measures, such as playing frequency, choice of game, and playing time. The characteristics of two distinct games were examined concerning the aspects of game experience, subjective game quality, and game usability. Interactions within the three aspects were identified. The results suggest that gameplay experience dimensions flow and immersion are similarly motivating in different game genres, which however might not be equally enjoyable. On the one hand, usability ratings may be positively influenced when a game provides immersion and flow or on the other hand, flow and immersion may be negatively influenced by poor usability ratings. These results emphasize the need for an approach to classify games based on correlation patterns involving game experience, quality, and usability.},

More Than a Feeling: Measurement of Sonic User Experience and Psychophysiology in a First-Person Shooter Game
@article{Nacke2010b,
Abstract = {The combination of psychophysiological and psychometric methods provides reliable measurements of affective user experience (UX). Understanding the nature of affective UX in interactive entertainment, especially with a focus on sonic stimuli, is an ongoing research challenge. In the empirical study reported here, participants played a fast-paced, immersive first-person shooter (FPS) game modification, in which sound (on/off) and music (on/off) were manipulated, while psychophysiological recordings of electrodermal activity (EDA) and facial muscle activity (EMG) were recorded in addition to a Game Experience Questionnaire (GEQ). Results indicate no main or interaction effects of sound or music on EMG and EDA. However, a significant main effect of sound on all GEQ dimensions (immersion, tension, competence, flow, negative affect, positive affect, and challenge) was found. In addition, an interaction effect of sound and music on GEQ dimension tension and flow indicates an important relationship of sound and music for gameplay experience. Additionally, we report the results of a correlation between GEQ dimensions and EMG/EDA activity. We conclude subjective measures could advance our understanding of sonic UX in digital games, while affective tonic (i.e., long-term psychophysiological) measures of sonic UX in digital games did not yield statistically significant results. One approach for future affective psychophysiological measures of sonic UX could be experiments investigating phasic (i.e., event-related) psychophysiological measures of sonic gameplay elements in digital games. This could improve our general understanding of sonic UX beyond affective gaming evaluation.},

Abstract = {Psychophysiological methods provide covert and reliable affective measurements of user experience (UX). The nature of affective UX in interactive entertainment is currently not well understood. With the dawn of new gaming consoles, scientific methodologies for studying user interaction in immersive entertainment (e.g., digital gaming) are needed. This paper reports a study on the influence of interaction modes (Playstation 2 game controller vs. Wii remote and Nunchuk) on subjective experience and brain activity measured with electroencephalography (EEG). Results indicate that EEG alpha and delta power correlate with negative affect and tension when using regular game controller input. EEG beta and gamma power seem to be related to the feeling of possible actions in spatial presence with a PS2 game controller. Delta as well as theta power correlate with self-location using a Wii remote and Nunchuk.},

The nature of affective UX in interactive entertainment is currently not well understood. With the dawn of new gaming consoles, scientific methodologies for studying user interaction in immersive entertainment (e.g., digital gaming) are needed. This paper reports a study on the influence of interaction modes (Playstation 2 game controller vs. Wii remote and Nunchuk) on subjective experience and brain activity measured with electroencephalography (EEG). Results indicate that EEG alpha and delta power correlate with negative affect and tension when using regular game controller input. EEG beta and gamma power seem to be related to the feeling of possible actions in spatial presence with a PS2 game controller. Delta as well as theta power correlate with self-location using a Wii remote and Nunchuk.

Affective Ludology, Flow and Immersion in a First-Person Shooter: Measurement of Player Experience
@article{Nacke_AL2009,
Abstract = {Gameplay research about experiential phenomena is a challenging undertaking,given the variety of experiences that gamers encounter when playing and whichcurrently do not have a formal taxonomy, such as flow, immersion, boredom, andfun. These informal terms require a scientific explanation. Ludologists alsoacknowledge the need to understand cognition, emotion, and goal- orientedbehavior of players from a psychological perspective by establishing rigorousmethodologies. This paper builds upon and extends prior work in an area forwhich we would like to coin the term "affective ludology." The area isconcerned with the affective measurement of player-game interaction. Theexperimental study reported here investigated different traits of gameplayexperience using subjective (i.e., questionnaires) and objective (i.e.,psychophysiological) measures. Participants played three Half-Life 2 game leveldesign modifications while measures such as electromyography (EMG),electrodermal activity (EDA) were taken and questionnaire responses werecollected. A level designed for combat-oriented flow experience demonstratedsignificant high-arousal positive affect emotions. This method shows thatemotional patterns emerge from different level designs, which has greatpotential for providing real-time emotional profiles of gameplay that may begenerated together with self- reported subjective player experience descriptions.},

Affective Ludology: Scientific Measurement of User Experience in Interactive Entertainment
@misc{Nacke2009h,
Abstract = {Digital games provide the most engaging interactive experiences. Researching gameplay experience is done mainly in the science and technology (e.g., human-computer interaction, physiological and entertainment computing) and social science (e.g., media psychology, psychophysiology, and communication sciences) research communities. This thesis is located at the intersection of these research areas, bringing together emerging methodological and scientific approaches from these multi-faceted communities for an affective ludology; a novel take on game analysis and design with focus on the player. The thesis contributes to game research with three important results: the establishment of a objective/subjective correlation methodology founded on psychophysiological methods, the creation of a formal theoretical framework in which to conduct user experience (UX) research related to games, and the combination of results regarding cognitive and emotional factors for describing, defining, and classifying the interactive relationship between players and games. Two approaches for measuring gameplay experience are used in this thesis. First, objective assessment of physiological user responses together with automated event-logging techniques, so called game metrics, allows collecting essential player- and game-related variables for a comprehensive understanding of their interaction. Second, using psychometric questionnaires allows a reliable assessment of players' subjective emotion and cognition during gameplay. The benefit of psychophysiological methods is that they are non-intrusive, covert, reliable, and objective. To fully understand psychophysiological results, a correlation between subjective gameplay experience ratings and psychophysiological responses is necessary and has been done in this thesis and prior work it builds on. This thesis explores objective and subjective assessment of gameplay experience in several experiments. The experiments focus on: level design implications from psychophysiological and questionnaire measurements, the impact of form and age on subjective gameplay experience, the impact of game audio and sound on objective and subjective player responses, and the impact of game interaction design on and the relationship between experience and electroencephalographic measures. In addition, the thesis includes a theoretical framework for UX research in games, which classifies gameplay experience along the dimensions of abstraction and time. One remaining conceptual and empirical challenge for this framework is the huge variety of vaguely defined experiential phenomena, such as immersion, flow, presence, and engagement. However, the results from the experimental studies show that by establishing correlations between psychophysiological responses and questionnaire data, we are approaching a better, scientifically grounded, understanding of gameplay experience. Many possibilities open from here. More detailed analyses of cognition will help us understand to what extent gameplay experience depends on emotional or cognitive processing. In addition, the inclusion of more complex and detailed gameplay metrics data together with psychophysiological metrics will enable a comprehensive analysis of player behavior, attention, and motivation. Finally, the integration of new measurement technologies in interactive entertainment applications will not only allow a detailed assessment of gameplay, but also improve physical and mental interaction with future games.},

Brain Training for Silver Gamers: Effects of Age and Game Form on Effectiveness, Efficiency, Self-Assessment, and Gameplay Experience.
@article{NackeEtAl2009a,
Abstract = {In recent years, an aging demographic majority in the Western world has come to the attention of the game industry. The recently released "brain-training" games target this population, and research investigating gameplay experience of the elderly using this game form is lacking. This study employs a 2 x 2 mixed factorial design (age group: young and old x game form: paper and Nintendo DS) to investigate effects of age and game form on usability, self-assessment, and gameplay experience in a supervised field study. Effectiveness was evaluated in task completion time, efficiency as error rate, together with self-assessment measures (arousal, pleasure, dominance) and game experience (challenge, flow, competence, tension, positive and negative affect). Results indicate players, regardless of age, are more effective and efficient using pen-and-paper than using a Nintendo DS console. However, the game is more arousing and induces a heightened sense of flow in digital form for gamers of all ages. Logic problem-solving challenges within digital games may be associated with positive feelings for the elderly but with negative feelings for the young. Thus, digital logic-training games may provide positive gameplay experience for an aging Western civilization.},

Abstract = {Assessing gameplay experience for gaze interaction games is a challenging task. For this study, a gaze interaction Half-Life 2 game modification was created that allowed eye tracking control. The mod was deployed during an experiment at Dreamhack 2007, where participants had to play with gaze navigation and afterwards rate their gameplay experience. The results show low tension and negative affects scores on the gameplay experience questionnaire as well as high positive challenge, immersion and flow ratings. The correlation between spatial presence and immersion for gaze interaction was high and yields further investigation. It is concluded that gameplay experience can be correctly assessed with the methodology presented in this paper.},
