The definitive version was published in CHI PLAY '15 Proceedings of the 2015 Annual Symposium on Computer-Human Interaction in Play, https://doi.org/10.1145/2793107.2810260Serious and persuasive games and gamified interactions have become popular in the last years, especially in the realm of behavior change support systems. They have been used as tools to support and influence human behavior in a variety of fields, such as health, sustainability, education, and security. It has been shown that personalized serious and persuasive games and gamified interactions can increase effectivity of supporting behavior change compared to "one-size-fits all"-systems. However, how serious games and gamified interactions can be personalized, which factors can be used to personalize (e.g. personality, gender, persuadability, player types, gamification user types, states, contextual/situational variables), what effect personalization has (e.g. on player/user experience) and whether there is any return on investment is still largely unexplored. This full-day workshop aims at bringing together the academic and industrial community as well as the gaming and gamification community to jointly explore these topics and define a future roadmap.Österreichische ForschungsförderungsgesellschaftPeer-reviewe

Gamification Strategies : A Characterization Using Formal Argumentation Theory

Gamified software applications are omnipresent in everyday life. The idea of using game design elements in non-game contexts to engage and motivate tasks has rapidly gained traction in the human–computer interaction and the psychology fields, but scarcely in the artificial intelligence (AI) research area. In this paper, we propose a software agent perspective of gamification elements to solve two specific problems: (1) a reactive perspective that gamification designers have for those gamified affordances, i.e. the visual cue (output) is only triggered by user interaction, and (2) a lack of formal treatment of gamified software, where strict characterization of software behavior as done in AI, guarantee that the information-based output follows the intended goal of the software. Our contributions presented in this paper are (1) two taxonomies of affordances based on the type of information that every element communicates, and the type of agency that is capable; (2) a framework to formalize the decision-making process for gamified software agents; and (3) a characterization of gamified stories using formal argumentation theory dialogues. We exemplify our contributions with two gamified platforms in the healthcare and financial literacy fields.© The Author(s) 2022.

Convergence of Gamification and Machine Learning: A Systematic Literature Review

Recent developments in human–computer interaction technologies raised the attention towards gamification techniques, that can be defined as using game elements in a non-gaming context. Furthermore, advancement in machine learning (ML) methods and its potential to enhance other technologies, resulted in the inception of a new era where ML and gamification are combined. This new direction thrilled us to conduct a systematic literature review in order to investigate the current literature in the field, to explore the convergence of these two technologies, highlighting their influence on one another, and the reported benefits and challenges. The results of the study reflect the various usage of this confluence, mainly in, learning and educational activities, personalizing gamification to the users, behavioral change efforts, adapting the gamification context and optimizing the gamification tasks. Adding to that, data collection for machine learning by gamification technology and teaching machine learning with the help of gamification were identified. Finally, we point out their benefits and challenges towards streamlining future research endeavors.publishedVersio

Understanding personal and contextual factors to increase motivation in gamified systems

Gamification, the use of game elements in non-game contexts, has been shown to help people reaching their goals, affect people's behavior and enhance the users' experience within interactive systems. However, past research has shown that gamification is not always successful. In fact, literature reviews revealed that almost half of the interventions were only partially successful or even unsuccessful. Therefore, understanding the factors that have an influence on psychological measures and behavioral outcomes of gamified systems is much in need. In this thesis, we contribute to this by considering the context in which gamified systems are applied and by understanding personal factors of users interacting with the system. Guided by Self-Determination Theory, a major theory on human motivation, we investigate gamification and its effects on motivation and behavior in behavior change contexts, provide insights on contextual factors, contribute knowledge on the effect of personal factors on both the perception and effectiveness of gamification elements and lay out ways of utilizing this knowledge to implement personalized gamified systems. Our contribution is manifold: We show that gamification affects motivation through need satisfaction and by evoking positive affective experiences, ultimately leading to changes in people's behavior. Moreover, we show that age, the intention to change behavior, and Hexad user types play an important role in explaining interpersonal differences in the perception of gamification elements and that tailoring gamified systems based on these personal factors has beneficial effects on both psychological and behavioral outcomes. Lastly, we show that Hexad user types can be partially predicted by smartphone data and interaction behavior in gamified systems and that they can be assessed in a gameful way, allowing to utilize our findings in gamification practice. Finally, we propose a conceptual framework to increase motivation in gamified systems, which builds upon our findings and outlines the importance of considering both contextual and personal factors. Based on these contributions, this thesis advances the field of gamification by contributing knowledge to the open questions of how and why gamification works and which factors play a role in this regard.Gamification, die Nutzung von Spielelementen in spielfremden Kontexten, kann nachweislich Menschen helfen, ihre Ziele zu erreichen, das Verhalten von Menschen zu beeinflussen und die Erfahrung der User in interaktiven Systemen zu verbessern. Allerdings hat die bisherige Forschung gezeigt, dass Gamification nicht immer erfolgreich ist. So haben Literaturübersichten ergeben, dass fast die Hälfte der Interventionen nur teilweise erfolgreich oder sogar erfolglos waren. Daher besteht ein großer Bedarf, die Faktoren zu verstehen, die einen Einfluss auf psychologische Maße sowie auf das Verhalten von Usern in gamifizierten Systemen haben. In dieser Arbeit tragen wir dazu bei, indem wir den Kontext, in dem gamifizierte Systeme eingesetzt werden, betrachten und persönliche Faktoren von Usern, die mit dem System interagieren, verstehen. Geleitet von der Selbstbestimmungstheorie, einer der wichtigsten Theorien zur menschlichen Motivation, untersuchen wir Gamification und dessen Auswirkungen auf Motivation und Verhalten in Kontexten zur Verhaltensänderung. Wir liefern Erkenntnisse über kontextuelle Faktoren, tragen Wissen über den Einfluss persönlicher Faktoren auf die Wahrnehmung und Effektivität von Gamification-Elementen bei und bieten Möglichkeiten, dieses Wissen für die Implementierung personalisierter gamifizierter Systeme zu nutzen. Unser Beitrag ist mannigfaltig: Wir zeigen, dass Gamification die Motivation durch Bedürfnisbefriedigung und durch das Hervorrufen positiver affektiver Erfahrungen beeinflusst, was letztlich zu Verhaltensänderungen führen kann. Darüber hinaus zeigen wir, dass das Alter, die Absicht, das Verhalten zu ändern, und Hexad-Usertypen eine wichtige Rolle bei der Erklärung von interpersonellen Unterschieden in der Wahrnehmung von Gamification-Elementen spielen. Ebenso zeigen unsere Resultate dass die Anpassung von gamifizierten Systemen auf Basis dieser persönlichen Faktoren positive Auswirkungen auf psychologische und verhaltensbezogene Ergebnisse hat. Letztlich zeigen wir, dass Hexad-Usertypen teilweise durch Smartphone-Daten und Interaktionsverhalten in gamifizierten Systemen vorhergesagt werden können und dass sie auf spielerische Art und Weise erhoben werden können. Dies ermöglicht, unsere Erkenntnisse in der Gamification-Praxis zu nutzen. Auf Basis dieser Ergebnisse schlagen wir ein konzeptuelles Framework zur Steigerung der Motivation in gamifizierten Systemen vor, das die Wichtigkeit der Berücksichtigung sowohl kontextueller als auch persönlicher Faktoren hervorhebt. Diese Erkenntnisse bereichern das Forschungsfeld Gamification, indem sie Wissen zu den offenen Fragen, wie und warum Gamification funktioniert und welche Faktoren in diesem Zusammenhang eine Rolle spielen, beitragen

Adaptive and Personalized Gamification Designs: Call for Action and Future Research

Gamification refers to the use of game-like elements in non-entertainment contexts to make activities more engaging and enjoyable to improve utilitarian outcomes. The gamification literature and the use of gamification in practice suggest that gamification can be a useful tool to support behavioral and psychological changes. Recent developments show that there is potential for new waves of gamification research. Therefore, we conducted a workshop at the International Conference on Wirtschaftsinformatik (WI) 2021 to discuss the future of gamification with interested scholars. The discussion with 25 gamification experts led to a research agenda that supports the need for adaptive and personalized gamification designs. Together with the experts, we identify three clusters for future research: 1) the personalization of gamification concepts, 2) theories and concepts for gamified human-computer interaction, and 3) the “dark side” of gamification (e.g., addiction). We also address what the gamification concept means. Aligned with the three clusters, we provide valuable starting points for future research inquiries to help researchers better understand the nature of gamification. We also discuss the capabilities and limits of gamification

Review of Serious Energy Games : Objectives, Approaches, Applications, Data Integration, and Performance Assessment

In recent years, serious energy games (SEGs) garnered increasing attention as an innovative and effective approach to tackling energy-related challenges. This review delves into the multifaceted landscape of SEG, specifically focusing on their wide-ranging applications in various contexts. The study investigates potential enhancements in user engagement achieved through integrating social connections, personalization, and data integration. Among the main challenges identified, previous studies overlooked the full potential of serious games in addressing emerging needs in energy systems, opting for oversimplified approaches. Further, these studies exhibit limited scalability and constrained generalizability, which poses challenges in applying their findings to larger energy systems and diverse scenarios. By incorporating lessons learned from prior experiences, this review aims to propel the development of SEG toward more innovative and impactful directions. It is firmly believed that positive behavior changes among individuals can be effectively encouraged by using SEG

Developing and evaluating MindMax: promoting mental wellbeing through an Australian Football League-themed app incorporating applied games (including gamification), psychoeducation, and social connectedness

Gamification is increasingly being used as a behavioural change strategy to increase engagement with apps and technologies for mental health and wellbeing. While there is promising evidence supporting the effectiveness of individual gamification elements, there remains little evidence for its overall effectiveness. Furthermore, a lack of consistency in how ‘gamification’ and related terms (such as ‘applied games’, an umbrella term of which gamification is one type) are used has been observed within and across multiple academic fields. This contributes to the difficulty of studying gamification and decreases its accessibility to people unfamiliar with applied games. Finally, gamification has also been critiqued by both game developers and by academics for its reliance on extrinsic motivators and for the messages that gamified systems may unintentionally convey. In this context, the aims of this thesis were fourfold: 1) to iteratively co-design and develop a gamified app for mental health and wellbeing, 2) to evaluate the eventuating app, 3) to consolidate literature on gamification for mental health and wellbeing, and 4) to synthesise findings into practical guidelines for implementing gamification for mental health and wellbeing. Chapter 2 reports the first study which addresses the first aim of this thesis. Six participatory design workshops were conducted to support the development of MindMax, an Australian Football League (AFL)-themed mobile phone app aimed at AFL fans (particularly male ones) that incorporates applied games, psychoeducation, and social connectedness. Findings from these workshops were independently knowledge translated and fed back to the software development team, resulting in a MindMax prototype. This prototype was further tested with 15 one-on-one user experience testing interviews at three separate time points to iteratively refine MindMax’s design and delivery of its content. The findings of this study suggest that broadly, participants endorsed a customisable user experience with activities requiring active user participation. These specifications were reflected in the continual software updates made to MindMax. Chapters 3 and 4 report the second and third studies which address the second aim of this thesis. As regular content, performance, and aesthetic updates were applied to MindMax (following the model of the wider tech industry), a naturalistic longitudinal trial, described in Chapter 3, was deemed to be the most appropriate systematic evaluation method. In this study, participants (n=313) were given access to MindMax and asked to use it at their leisure, and surveys were sent out at multiple time points to assess their wellbeing, resilience, and help-seeking intentions. Increases in flourishing (60-day only), sense of connection to MindMax, and impersonal help-seeking intentions were observed over 30 and 60 days, suggesting that Internet-based interventions like MindMax can contribute to their users’ social connectedness and encourage their help-seeking. The third study, described in Chapter 4, reports a secondary analysis of data collected for Chapter 3, and further explores participants’ help-seeking intentions and their links to wellbeing, resilience, gender, and age. An explanatory factor analysis was conducted on Day 1 General Help-Seeking Questionnaire (GHSQ) data (n=530), with the best fitting solution resulting in three factors: personal sources, health professionals, and distal sources. In addition to providing more evidence that younger people aged 16–35 categorise apps and technologies for mental health and wellbeing like MindMax alongside other distal social sources such as phone helplines and work or school, our findings also suggest that the best way to target individuals who are least likely to seek help, particularly men, may be through these distal sources as well. Chapter 5 reports the fourth study, which addresses the third aim. In order to consolidate literature on gamification for mental health and wellbeing, this systematic review identified 70 papers that collectively reported on 50 apps and technologies for improving mental health and wellbeing. These papers were coded for gamification element, mental health and wellbeing domain, and researchers’ justification for applying gamification to improving mental health and wellbeing. This study resulted in two major findings: first, that the current application of gamification for mental health and wellbeing does not resemble the heavily critiqued mainstream application that relies on extrinsic motivators; and second, that many authors of the reviewed papers provided little or no justification for why they applied gamification to their mental health and wellbeing interventions. While the former finding is encouraging, the latter suggests that the gamification of mental health and wellbeing is not theory-driven, and is a cause for concern. Finally, to address the final aim of this thesis, all study learnings were synthesised into practical guidelines for implementing gamification for mental health and wellbeing. First, it is important to assess the suitability of implementing gamification into the intervention. Second, this implementation should ideally be integrated at a deeper, systemic level, with the explicitly qualified intention to support users, evidence-based processes, and user engagement with these processes. Third, it is important to assess the acceptability of this gamified intervention throughout its development, involving all relevant stakeholders (particularly representative end user populations). Fourth, it is important to evaluate the impact of this gamified intervention. Fifth, and finally, comprehensive and detailed documentation of this process should be provided at all stages of this process. This thesis contributes to a growing literature on the increasing importance and relevance of Internet-based resources and apps and technologies for mental health and wellbeing, particularly for young people. Given the dominance of games in society and culture across history, and the increasing contemporary prominence of digital games (also known as video games) in particular, gamification is uniquely positioned to have the potential to make large contributions to mental health and wellbeing research. In this context, this thesis contributes a systematically derived operationalisation of gamification, an evaluation of a gamified app for mental health and wellbeing, and best practice guidelines for implementing gamification for mental health and wellbeing, thereby providing frameworks that future implementations of gamified mental health and wellbeing interventions and initiatives may find useful

Towards a Persuasive Design Pattern for a Gamified M-Learning Environment

New innovative technologies create opportunities for persuasive engagement. Persuasive technology is all about software, systems and applications designed to hook, reinforce, change and shape the attitudes of the learners without using coercion or deception. Persuasive design pattern if applied effectively and efficiently may influence learners’ attitudes towards the learning task, and may hook them to the specific learning activity offered via a gamified mobile application. In this paper the concept of persuasive design pattern in gamified m-learning platforms should be introduced to the scientific community. Persuasive design in a gamified mobile learning environment is described and persuasive set of design patterns appropriate to a gamified mobile environment is introduced. These persuasive design pattern are divided into three categories to suit to the appropriate learning environment
