With the proliferation of hedonic information systems, understanding users' acceptance of hedonic information systems has become a new topic for practitioners and academics. While perceived playfulness or perceived enjoyment has been found to have a significant influence on the behavioral intention to use hedonic information systems, little research has been conducted to Investigate empirically the antecedents of perceived playfulness and the mediating role that perceived playfulness has in user acceptance of hedonic information systems. Thus, the main purpose of this study is to explore the mediating role of perceived playfulness in the psychological process of user acceptance of hedonic online game systems. Based on previous literature, two individual difference variables (i.e., computer self-efficacy and computer anxiety) and three system characteristics variables (i.e., challenge, feedback, and speed) were proposed as potential antecedents of perceived playfulness in the context of massive multiplayer online games. The results indicate that perceived playfulness plays a partial mediating role in the relationship of system characteristics and individual differences to behavioral intention. Both challenge and computer self-efficacy were found to have a significant influence on behavioral intention via perceived playfulness, with computer self-efficacy also having a direct influence on behavioral intention. Computer anxiety, however, was only found to have a direct influence on behavioral intention. Also, neither feedback nor speed was found to have a significant effect on perceived playfulness. The results of this study provide several important implications for research and practices of hedonic information systems/online game design and promotion.

The aims of this research were to describe Finnish adolescents' different motives for digital game playing, and to examine relations between digital game playing and parent-child communication, school performance, sleeping habits, and perceived health. A questionnaire was used to assess a nationwide postal sample of 12-18-year-old Finns (6761 respondents, response rate 69%) in winter 2003. Among respondents, 4085 adolescents played digital games and answered questions on digital game motives. Two main motives emerged: instrumental (learn new things and procedures, have a common topic for conversation, use and develop game playing skills, experience different roles/worlds) and ritualized (pastime, entertainment; recover, relax; escape everyday life, forget worries). The importance of all motives increased for participants with longer playing times. Instrumental motives were more important to boys and younger respondents. They were associated with earlier bedtime, worse perceived health, better mother communication, and better school grades, but only among boys. The importance of ritualized motives increased with age and was related to better school performance, worse sleeping habits, and worse perceived health in both sexes. Digital games seem to have the same basic functions as media in serving adolescents' mood management and stimulation seeking. Among boys, gaming is part of the male socio-cultural communication context. (C) 2009 Elsevier Inc. All rights reserved.

Games technology has undergone tremendous development. In this article, the authors report the rapid advancement that has been observed in the way games software is being developed, as well as in the development of games content using game engines. One area that has gained special attention is modeling the game environment such as terrain and buildings. This article presents the continuous level of detail terrain modeling techniques that can help generate and render realistic terrain in real time. Deployment of characters in the environment is increasingly common. This requires strategies to map scalable behavior characteristics for characters as well. The authors present two important aspects of crowd simulation: the realism of the crowd behavior and the computational overhead involved. A good simulation of crowd behavior requires delicate balance between these aspects. The focus in this article is on human behavior representation for crowd simulation. To enhance the player experience, the authors present the concept of player adaptive entertainment computing, which provides a personalized experience for each individual when interacting with the game. The current state of game development involves using very small percentage (typically 4% to 12%) of CPU time for game artificial intelligence (AI). Future game AI requires developing computational strategies that have little involvement of CPU for online play, while using CPU's idle capacity when the game is not being played, thereby emphasizing the construction of complex game AI models offline. A framework of such nonconventional game AI models is introduced.

Computer games are now becoming ways to communicate, teach, and influence attitudes and behavior. In this article, we address the role of humor in computer games, especially in support of serious purposes. We begin with a review of the main theories of humor, including superiority, incongruity, and relief. These theories and their interrelationships do well in helping us understand the humor process, but they have been developed in the context of traditional human activity. To explore how they relate to computer games, we present the findings of a qualitative study of player experience of humor and show how it relates to the theoretical perspectives. We then review the main functions of humor, especially its effects on social, emotional, and cognitive behavior. We show how each of these functions can be used in game design to support the specific experiences and outcomes of game-play. Finally, we address the issue of serious games and make suggestions on how humor can inform and support the design of those games. We suggest that humor can support design by smoothing and sustaining the game mechanics. Moreover, games can draw on the functions of humor in the real world for enhancing communication, learning, and social presence. Using humor makes games richer and more powerful, as well as fun.

This letter proposes a categorization matrix to analyze the playing style of a computer game player for a shooting game genre. Our aim is to use human-centered modeling as a strategy for adaptive games based on entertainment measure to evaluate the playing experience. We utilized a self-organizing map (SOM) to cluster the player's style with the data obtained while playing the game. We further argued that style-based adaptation contributes to higher enjoyment, and this is reflected in our experiment using a supervised multilayered perceptron (MLP) network.

Pervasive games are rapidly maturing - from early research experiments with locative games we now start to see a range of commercial projects using locative and pervasive technology to create technology-supported pervasive games. In this paper we report on our experiences in transferring the successful involvement of players in computer games to 'modding' for pervasive games. We present the design process, the enabling tools and two sample games provided in boxes to end users. Finally we discuss how our findings inform the design of 'modding' tools for a pervasive game community of the future.

We adapted the computer game TETRIS to investigate the process of affective-motivational counter-regulation, that is, attentional biases for emotional stimuli that are in opposition to the momentary Motivational focus. Counter-regulation is seen as a mechanism which should prevent escalation and impulsivity, and it should help to avoid becoming "locked up" in affective-motivational states. Accordingly, for a negative outcome focus condition (i.e., risk of losing a current high score), we hypothesized greater interference by positive distractors that were included in the game, whereas for a positive outcome focus (i.e., chance to improve one's current high score), we hypothesized greater interference by negative distractors. Supporting our hypotheses, we found the predicted interactions between distractor valence and type of outcome focus. (C) 2009 Elsevier B.V. All rights reserved.

Background: Although considerable research suggests that health-risk factors vary as a function of video-game playing among young people, direct evidence of such linkages among adults is lacking.Purpose: The goal of this Study was to distinguish adult video-game players from nonplayers on the basis of personal and environmental factors. It was hypothesized that adults who play video games, compared to nonplayers, would evidence poorer perceptions of their health, greater reliance on Internet-facilitated social support, more extensive media use, and higher BMI. It was further hypothesized that different patterns of linkages between video-game playing and health-risk factors would emerge by gender.Methods: A cross-sectional, Internet-based survey was conducted in 2006 with a sample of adults from the Seattle-Tacoma area (n=562), examining health risks; media use behaviors and perceptions, including those related to video-game playing; and demographics. Statistical analyses conducted in 2008 to compare video-game players and nonplayers included bivariate descriptive statistics, stepwise discriminant analysis, and ANOVA.Results: A total of 45.1% of respondents reported playing video games. Female video-game players reported greater depression (M=1.57) and poorer health status (M=3.90) than female nonplayers (depression, M=1.13; health status, M=3.57). Male video-game players reported higher BMI (M=5.31) and more Internet use time (M=2.55) than male nonplayers (BMI, M=5.19; Internet use, M=2.36). The only determinant common to female and male video-game players was greater reliance on the Internet for social support.Conclusions: A number of determinants distinguished video-game players from nonplayers, and these factors differed substantially between men and women. The data illustrate the need for further research among adults to clarify how to use digital opportunities more effectively to promote health and prevent disease. (Am J Prev Med 2009;37(4):299-305)

Acts of interpersonal touch - a touch shared between two people are used by couples to communicate in a simple and emotionally intimate way. In this paper, we argue that the intimacy afforded by acts of interpersonal touch can be used in computer entertainment to support enjoyable and engaging activities for couples. To support this notion, we have developed Matchmaker; a two-player, cooperative tabletop video game based on themes of love and romance. Matchmaker's gameplay is directly controlled by a set of collaborative tabletop interaction techniques, as well as by acts of interpersonal touch between its players. In this paper we present a detailed description of Matchmaker's design and the results of an exploratory user suggesting that Matchmaker is enjoyable to play and that its use of interpersonal touch contributes to players' enjoyment.

A large-scale content analysis of characters in video games was employed to answer questions about their representations of gender, race and age in comparison to the US population. The sample included 150 games from a year across nine platforms, with the results weighted according to game sales. This innovation enabled the results to be analyzed in proportion to the games that were actually played by the public, and thus allowed the first statements able to be generalized about the content of popular video games. The results show a systematic over-representation of males, white and adults and a systematic under-representation of females, Hispanics, Native Americans, children and the elderly. Overall, the results are similar to those found in television research. The implications for identity, cognitive models, cultivation and game research are discussed.
