Perceived control and gender difference on the relationship between trialability and intent to play new online games

With the growing number of online game players and the increasing of new online games development, it is imperative for marketers to develop a better understanding of players’ new game adoption decisions. This study examines perceived control as a mediator of trialability-product adoption relationship, and gender difference as a moderator of the relationship between trialability-product adoptions. A field survey was conducted to test the hypotheses of the study. Respondents were graduate students from Taiwan universities. A total of 411 undergraduate students with massively multiplayer online gaming (MMOGs) experience participated in this study. The structural equation model (SEM) method was employed to analyze the data. The findings indicate that perceived product trialability has a direct influence on intent to play new games, and indirect effects through perceived process control. Gender differences also moderate the trialability effects on the adoption of new online games. Perceived trialability had more of an effect on intention to play new online games for female players than for male players. To develop an effective product development and communication strategy, the finding suggests that online game firms should focus on new product characteristics and consider consumer gender differences.

Defining the virtual self: Personality,behavior, and the psychology of embodiment

Although researchers have discussed the existence of a virtual self, or embodiment of human characteristics within an avatar, little known about how the virtual self influences a player’s behavior within a virtual environment. To better understand this relationship, World of Warcraft game players were asked to complete personality-rating scales for both themselves and their avatars. In addition, in-world behavior was recorded and then analyzed using a behavioral assessment checklist. Results suggested a relationship between personality and behavior within the domain of agreeableness. Based on these findings, the researchers discuss implications for the construct known as the virtual self, as well as the inclusion of psychological systems design into the overall game design process.     

Interactive effects of individual- and group-level variables on virtual purchase behavior in online communities

Focusing on social network theories, we examine the interactive influence of both group-level (i.e. community influences) and individual-level variables (intrinsic and extrinsic motivations) simultaneously as the drivers of Massively Multiplayer Online Role-Playing Game (MMORPG) players’ virtual purchase behavior. We demonstrate that several aspects of real-world behavior are reflected in virtual purchase behavior. Notably, normative interpersonal influences and community identity are critical drivers and moderators of virtual purchases. Moreover, clear advancement and enjoyment opportunities offer important triggers for virtual purchase behavior. This study provides insights for game developers to increase virtual purchases, and identifies domain-specificity of each gaming platform.     

Event-triggered optimal tracking control of multiplayer unknown nonlinear systems via adaptive critic designs

In this article, the event-triggered optimal tracking control problem for multiplayer unknown nonlinear systems is investigated by using adaptive critic designs. By constructing a neural network (NN)-based observer with input–output data, the system dynamics of multiplayer unknown nonlinear systems is obtained. Subsequently, the optimal tracking control problem is converted to an optimal regulation problem by establishing a tracking error system. Then, the optimal tracking control policy for each player is derived by solving coupled event-triggered Hamilton-Jacobi (HJ) equation via a critic NN. Meanwhile, a novel weight updating rule is designed by adopting concurrent learning method to relax the persistence of excitation (PE) condition. Moreover, an event-triggering condition is designed by using Lyapunov's direct method to guarantee the uniform ultimate boundedness (UUB) of the closed-loop multiplayer systems. Finally, the effectiveness of the developed method is verified by two different multiplayer nonlinear systems.     

基于P2P的MMOG中动态负载均衡算法

P2P技术在解决大规模网络游戏的伸缩性方面提供了很好的解决方案。但是由于节点的计算能力和带宽方面的异构性,网络游戏系统应该具有一定的负载均衡能力,即能够以较小的负载迁移率动态地将负载从超载节点迁移到轻载节点中。该文提出了一种在游戏动态运行过程中的一种动态负载均衡算法。实验表明,该算法能够有效地均衡负载分布和降低负载迁移率。
