Designing social videogames for educational uses

In this paper we analyze the main areas of research into educational videogames and in the evolution of the technologies and design methodologies that are making these interactive systems increasingly natural, immersive and social. We present the design and development of a prototype for a collaborative educational videogame based on a Massively Multiplayer Online Role-Playing Game (MMORPG) engine for use in various educational contexts in (a) university education and (b) secondary education.     

控位滑行航行器的运动分析与弹道仿真

控位滑行航行器是一种结构简单、能源的利用率高,同时机动性也较好的新型水下航行器.为了解决控位滑行航行器的运动优化控制,针对控位滑行航行器的滑翔和近水面的控位运动稳定性问题,利用控位和滑翔运动特点,根据动量和动量矩定理建立了航行器空间运动数学模型,通过MATLAB/ Simulink软件模块建立了航行器空间六自由度运动仿真模型,并对滑翔和控位运动弹道进行了仿真,分析总结了航行器在不同运动模式和工况下的稳定性,并对不同参数条件下的航行器稳定性品质和衰减历程进行了对比.结果表明在给定的初始条件下控位滑行航行器是能按照预设轨迹航行,完成航行任务,满足设计要求的.     

Player–video game interaction: A systematic review of current concepts

Video game design requires a user-centered approach to ensure that the experience enjoyed by players is as good as possible. However, the nature of player–video game interactions has not as yet been clearly defined in the scientific literature. The purpose of the present study was to provide a systematic review of empirical evidences of the current concepts of player–video game interactions in entertainment situations. A total of 72 articles published in scientific journals that deal with human–computer interaction met the criteria for inclusion in the present review. Major findings of these articles were presented in a narrative synthesis. Results showed that player–video game interactions could be defined with multiple concepts that are closely linked and intertwined. These concepts concern player aspects of player–video game interactions, namely engagement and enjoyment, and video game aspects, namely information input/output techniques, game contents and multiplayer games. Global approaches, such as playability, also exist to qualify player–video game interactions. Limitations of these findings are discussed to help researchers to plan future advances of the field and provide supplementary effort to better know the role of less-studied aspects. Practical implications are also discussed to help game designers to optimize the design of player–video game interactions.
