Designing for Disengagement: Challenges and Opportunities for Game Design to Support Children's Exit From Play

Games research and industry have developed a solid understanding of how to design engaging, playful experiences that draws players in for hours and causes them to lose their sense of time. While these designs can provide enjoyable experiences, many individuals -- especially children -- may find it challenging to regulate their playing time, and often they struggle to turn off the game. In turn, this affords external regulation of children's playing behavior by limiting playing time or encouraging alternative activities, which frequently leads to conflicts between parents and the children. Here, we see an opportunity for game design to address player disengagement through design, facilitating a timely and autonomous exit from play. Hence, while most research and practitioners design for maximizing player engagement, we argue for a perspective shift towards disengagement as a design tool that allows for unobtrusive and smooth exits from the game. We advocate that interweaving disengagement into the game design could reduce friction within families, allowing children to finish game sessions more easily, facilitate a sense of autonomy, and support an overall healthier relationship with games. In this position paper, we outline a research agenda that examines how game design can address player disengagement, what challenges exist in the specific context of games for children, and how such approaches can be reconciled with the experiential, artistic, and commercial goals of games

Violent video games and attitudes towards victims of crime: an empirical study among youth

Previous research has indicated that playing violent video games may be associated with an increase in acceptance of violence and positive attitudes towards perpetrators of crime. This study is the first to investigate the relationship between playing violent video games and attitudes towards victims of crime. A total of 206 young people (aged 12-24 years) completed measures of attitudes towards victims and violent video game exposure. The results suggest that exposure to violent video games is associated with less concern being reported for victims of crime. Young people who play more violent video games reported less concern for general victims and for culpable victims, and these effects cannot be explained by gender or age differences. The results are discussed in relation to relevant research in the area, along with recommendations for future research

Eye quietness and quiet eye in expert and novice golf performance: an electrooculographic analysis

Quiet eye (QE) is the final ocular fixation on the target of an action (e.g., the ball in golf putting). Camerabased eye-tracking studies have consistently found longer QE durations in experts than novices; however, mechanisms underlying QE are not known. To offer a new perspective we examined the feasibility of measuring the QE using electrooculography (EOG) and developed an index to assess ocular activity across time: eye quietness (EQ). Ten expert and ten novice golfers putted 60 balls to a 2.4 m distant hole. Horizontal EOG (2ms resolution) was recorded from two electrodes placed on the outer sides of the eyes. QE duration was measured using a EOG voltage threshold and comprised the sum of the pre-movement and post-movement initiation components. EQ was computed as the standard deviation of the EOG in 0.5 s bins from –4 to +2 s, relative to backswing initiation: lower values indicate less movement of the eyes, hence greater quietness. Finally, we measured club-ball address and swing durations. T-tests showed that total QE did not differ between groups (p = .31); however, experts had marginally shorter pre-movement QE (p = .08) and longer post-movement QE (p < .001) than novices. A group × time ANOVA revealed that experts had less EQ before backswing initiation and greater EQ after backswing initiation (p = .002). QE durations were inversely correlated with EQ from –1.5 to 1 s (rs = –.48 - –.90, ps = .03 - .001). Experts had longer swing durations than novices (p = .01) and, importantly, swing durations correlated positively with post-movement QE (r = .52, p = .02) and negatively with EQ from 0.5 to 1s (r = –.63, p = .003). This study demonstrates the feasibility of measuring ocular activity using EOG and validates EQ as an index of ocular activity. Its findings challenge the dominant perspective on QE and provide new evidence that expert-novice differences in ocular activity may reflect differences in the kinematics of how experts and novices execute skills

Player retention in league of legends: A study using survival analysis

© 2018 ACM. Multi-player online esports games are designed for extended durations of play, requiring substantial experience to master. Furthermore, esports game revenues are increasingly driven by in-game purchases. For esports companies, the trends in players leaving their games therefore not only provide information about potential problems in the user experience, but also impacts revenue. Being able to predict when players are about to leave the game-churn prediction-is therefore an important solution for companies in the rapidly growing esports sector, as this allows them to take action to remedy churn problems. The objective of the work presented here is to understand the impact of specific behavioral characteristics on the likelihood of a player continuing to play the esports title League of Legends. Here, a solution to the problem is presented based on the application of survival analysis, using Mixed Effects Cox Regression, to predict player churn. Survival Analysis forms a useful approach for the churn prediction problem as it provides rates as well as an assessment of the characteristics of players who are at risk of leaving the game. Hazard rates are also presented for the leading indicators, with results showing that duration between matches played is a strong indicator of potential churn
