    The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-10422-5_22In order to achieve flow and increase player retention, it is important that games di culty matches player skills. Being able to evaluate how people play a game is a crucial component for detecting gamers strategies in videogames. One of the main problems in player strategy detection is whether attributes selected to define strategies correctly detect the actions of the player. In this paper, we will study a Real Time Strategy (RTS) game. In RTS the participants make use of units and structures to secure areas of a map and/or destroy the opponents resources. We will extract real-time information about the players strategies at several gameplays through a Web Platform. After gathering enough information, the model will be evaluated in terms of unsupervised learning (concretely, KMeans). Finally, we will study the similitude between several gameplays where players use di erent strategies

    In recent years, problematic and addictive gaming has been a phenomenon of growing concern worldwide. In light of the increasing awareness about this issue, the latest (fifth) edition of the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders (DSM-5) included Internet Gaming Disorder (IGD) as an area in need of more empirical research. The Internet Gaming Disorder Test (IGD-20 Test) was developed as a valid and reliable tool to assess IGD. The aim of the present study was to validate the Spanish version of the IGD-20 Test, and analyze the different profiles found among a sample of 1,074 Spanish-speaking gamers. A confirmatory factor analysis showed the validity of the Spanish version of the IGD-20 Test and its six factor structure (i.e., salience, mood modification, tolerance, withdrawal, conflict and relapse). The latent profile analysis (LPA) showed five different gamer classes. The 'disordered gamers’ class comprised 2.6% of the participants. Based on this class, sensitivity and specificity analyses showed an adequate empirical cut-off point of 75 (out of 100). It is concluded that the Spanish version of the IGD-20 Test is valid and reliable and can be used in research into IGD among Spanish speaking populations

    Aims: Although the general public appears to have embraced the term 'video game addiction', the scientific debate as to whether 'gaming addiction' can actually be considered an addiction similar to substance addictions of DSM-IV is still unsettled. To date, research on gaming addiction has focused on problematic behavior from the gaming activity itself and there has been little empirical research related to pathological personality patterns that usually are associated with substance addictions. Therefore, the current study examined how excessive gaming and ‘problematic gaming behavior’ are related to personality patterns associated with addiction by means of the Minnesota Multiphasic Personality Inventory-2 MMPI-2). Design, setting, and participants: A large-scale survey study among 1,004 adolescent boys (age-range 11-18 years; M =14.18, SD=1.36; response rate 96.17%). Measurements: Problematic gaming behavior, physical game-related symptoms, gaming behavior and three MMPI-2 subscales measuring personality patterns usually associated with substance addiction (MAC-R, APS, AAS) were assessed. Findings: Results showed that problematic gaming and physical game-related symptoms were positively related to all three substance abuse subscales of the MMPI-2. Conclusions: Problematic gaming should be clearly distinguished from excessive gaming. In short, excessive gaming merely indicates enthusiasm for some although it may be psychopathological for others

    PREDICTING CROSS-GAMING PROPENSITY USING E-CHAID ANALYSIS

    Cross-selling different types of games could provide an opportunity for casino operators to generate additional time and money spent on gaming from existing patrons. One way to identify the patrons who are likely to cross-play is mining individual players’ gaming data using predictive analytics. Hence, this study aims to predict casino patrons’ propensity to play both slots and table games, also known as cross-gaming, by applying a data-mining algorithm to patrons’ gaming data. The Exhaustive Chi-squared Automatic Interaction Detector (E-CHAID) method was employed to predict cross-gaming propensity. The E-CHAID models based on the gaming-related behavioral data produced actionable model accuracy rates for classifying cross-gamers and non-cross gamers along with the cross-gaming propensity scores for each patron. Using these scores, casino managers can accurately identify likely cross-gamers and develop a more targeted approach to market to them. Furthermore, the results of this study would enable casino managers to estimate incremental gaming revenues through cross-gaming. This, in turn, will assist them in spending marketing dollars more efficiently while maximizing gaming revenues

    This report examines the role interactive entertainment plays in Australian households. Foreword We began national studies of computer game audiences in 2005 to widen the conversation about games and tackle stereotypes that prevented an understanding in the wider community that computer games were a popular medium that had become not only normalised, but a medium valued by Australians of all ages. Rather than challenge negative stereotypes about games with rhetoric, we provided quantitative empirical data using established social and market research practice – something that had not been available for Australia’s journalists and policy-makers who relied on overseas data. Over the five Australian studies since 2005, we documented the ascendency of computer and video games to centre stage in media culture. Game Play Australia 2005 conveyed the reality that Australia is a nation of game-lovers who enjoy playing games on a sporting field and on the screen. In 2005: 76% of households had a device for playing games and PCs dominated consoles, 38% of gamers were female and the average age was 24, Less than an hour was the play duration and twice a week was the frequency 49% of households had broadband connections, 35% played games online, 66% of parents played video games, 88% said Australia should have an R18+ for games, and 68% said classification information was very influential when choosing games for their children. Interactive Australia 2007 and 2009 illustrated the growing ability of games to foster social interaction. Moreover, games consoles and the Internet had matured and grown in popularity. By 2009: 88% of households had a device for playing games and consoles took the lead from PCs, 46% of gamers were female and the average age was 30, An hour was the play duration and every other day was the frequency, 81% of households had broadband connections, 48% played games online, 70% of parents played games, 60% of households were home to 2 or more players, 91% said Australia should have an R18+ for games, and 46% said classification information was very influential when choosing games for their children. Digital Australia 2012 illustrated the rapid maturation of digital media and more avenues for game experiences to anyone who wanted to play. By 2012: 92% of households had a device for playing games and consoles lead and phones outflanked handhelds, 47% of gamers were female and the average age was 32, An hour was the play duration and every other day was the frequency, 83% of parents played games, 70% of households were home to 2 or more players, and 41% said classification information was very influential when choosing games for their children. Digital Australia 2014 completes this phase of reports on computer games and Australians. The profile of the gamer and the gaming household is nearly synonymous with the profile of the typical Australian and Australian household. It demonstrates that multiple screens and game devices are commonplace and that games have expanded from the loungeroom to the pocket, played frequently and for longer durations. It suggests that the moral panic over established media like music, films, television and games is now moving to social media and the Internet. Adult gamers have formed great memories over the years of family time, characters, story, play and interaction from a medium that has emerged from its adolescence.   Authored by Jeffrey E.

    The differences between self-reported and observed emotion have only marginally been investigated in the context of speech-based automatic emotion recognition. We address this issue by comparing self-reported emotion ratings to observed emotion ratings and look at how differences between these two types of ratings affect the development and performance of automatic emotion recognizers developed with these ratings. A dimensional approach to emotion modeling is adopted: the ratings are based on continuous arousal and valence scales. We describe the TNO-Gaming Corpus that contains spontaneous vocal and facial expressions elicited via a multiplayer videogame and that includes emotion annotations obtained via self-report and observation by outside observers. Comparisons show that there are discrepancies between self-reported and observed emotion ratings which are also reflected in the performance of the emotion recognizers developed. Using Support Vector Regression in combination with acoustic and textual features, recognizers of arousal and valence are developed that can predict points in a 2-dimensional arousal-valence space. The results of these recognizers show that the self-reported emotion is much harder to recognize than the observed emotion, and that averaging ratings from multiple observers improves performance

    The popularity of Massively Multi-Player Online Role-Playing Games (MMORPGs) has risen dramatically over the last decade. Some gamers spend many hours a day in these virtual environments interacting with others gamers, completing quests, and forming social groups. The present study set out to explore the experiences and feelings of online gamers. The study comprised 71 interviews with online gamers (52 males and 19 females) from 11 different countries. Many themes emerged from the analyses of the interview transcripts including (i) relationship with social networking, (ii) social interaction, (iii) the community, (iv) learning real-life skills, (v) reinforcement schedules and operant conditioning, (vi) game design and content, (vii) escaping from real life, (viii) playing longer than intended, and (ix) gamers’ obligations towards others in online worlds. These findings specifically showed the social networking capabilities of online gaming, the community aspects and the psychological mechanisms within MMORPGs that can lead to excessive online gaming. The implications of these findings are discussed in relation to previous qualitative and quantitative research in the area
