Abstract: "A key problem for crowd - sourced systems is motivating contributions from participants and ensuring the quality of these contributions. Games have been suggested as a motivational approach but there are concerns about data quality , particularly when the data are to be used for scientific research . To address these concerns, w e compare the quality of data obtained from two citizen science games, one a "gamified" version of a species classificatio n task and one a fantasy game that used the classification task only as a way to advance in the game play. Surprisingly, though we did observe cheating in the fantasy game, data quality from the two games was not significantly different . As well, the quali ty of data from short - time contributors was at a usable level. These findings suggest that games can be a useful way to motivate contributions to citizen science projects. "

Abstract: "This paper presents data analysis from a course on Software Engineeri ng in an effort to identify metric s and techniques that would allow instructor to act proactively and identify patterns of low engagement and inefficient peer collaboration . Over the last two terms, 106 students in their second year of studies formed 20 groups and worked collaboratively to develop video games. Throughout the lab, students have to use a variety of tools for managing and developing their projects, such as software version control , static analysis tools , wikis, mailing lists, etc . The students are also supported by weekly meet ings with teaching assistants and instructors regarding group progress, code quality, and management issues. Through these meeting s and their interactions with the software tools, students leave a detailed trace of data related to their individual engageme nt and their collaboration behavior in their groups . The paper provides discussion on the different source of data that can be monitored , and present preliminary results on how the s e data can be used to analyze students' activity."

Abstract: "Cloud gaming now makes any computer game playable on a thin client without the previous worries and frustrations about the hardware requirements. It frees players from the need to frequently upgrade their computers as they can now play games that are hosted on remote servers with a broadband Internet connection and a thin client. However, cloud games are intrinsically more susceptible to latency than online games because game graphics are rendered on cloud servers and thin clients do not possess game state information that is required by delay compensation techniques. In this paper, we investigate how the response latency in cloud gaming would affect users' experience and how the impact of latency on players' experience varies among different games. We show that not all games are equally friendly to cloud gaming. That is, the same degree of latency may have very different impacts on a game's quality of experience depending on the game's real-time strictness. We thus develop a model that can predict a game's real-time strictness based on the rate of players' inputs and the game screen dynamics. The model can be used to simultaneously enhance players' gaming and optimize the operation cost of data centers."

Abstract: "Citizen science is a form of social computation where members of the public are recruited to contribute to scientific investigations. Citizen-science projects often use web-based systems to support collaborative scientific activities, making them a form of computer-supported cooperative work. However, finding ways to attract participants and confirm the veracity of the data they produce are key issues in making such systems successful. We describe a series of web-based tools and games currently under development to support taxonomic classification of organisms in photographs collected by citizen-science projects. In the design science tradition, the systems are purpose-built to test hypotheses about participant motivation and techniques for ensuring data quality. Findings from preliminary evaluation and the design process itself are discussed."

Abstract: "Through the use of an online discussion, this study collected the detailed perspectives of 29 'hardcore' and 'casual' gamers, regarding the topic of FPS video games. It investigates what the gamers want in a FPS by means of an online discussion which builds on the benefits of both ethnography and focus group methodologies. Since the study's main goal was exploratory, a qualitative approach was considered the most appropriate; in addition to this, the method used to collect the data was done within a grounded theory framework. This study finds that, though graphics have historically been a major factor in driving the success of a FPS video game, this is no longer the case. Gamers expect there to be a balance between the different components, with a more holistic gaming experience desired, and that too much focus on one component at the expense of another will result in an unsatisfactory video game experience. This can be seen in comments given by the participants indicating too much emphasis of the graphics quality in a FPS and not enough on story or the multiplayer aspects results in a video game which is neither fun nor praiseworthy. The latter is perceived significant as with such an oversaturation in the video game market, developers rely heavily on positive word of mouth to advertise their games. This study's main goal was to develop a better understanding of the expectations of gamers regarding FPS; in doing so, it has laid out the basis for producing a 'magic formula' for a great FPS video game. It has also highlighted several other areas which need further investigation in order to better understand the behavioural motives and actions of gamers from both 'hardcore' and 'casual' communities."

"Digital technology empowers one to access vast amounts of on-line data. From a learning perspective, however, it is difficult to access meaningful on-site information within a given context. The Hypercontextualized Game (HCG) design model interweaves on-site resources, translated as content, and the digital game. As a local game design process, HCG builds on the resources available on-site (context) and transfers them beyond their origin (hyper). A successful example is the HCG stories in LieksaMyst, an application developed for the Pielinen Museum, in which the player is guided through a series of activities by a virtual host from the historic past. It took three years of extensive work and research for the LieksaMyst HCG stories to mature from brainstorming concepts to a fully-fledged museum service. Curators, educational technology experts and a total of 476 visitors (from 6 to 77 years old) contributed to the design process. The analysis of the context and feedback from the visitors enabled us to choose media, content and activities suitable to the Pielinen Museum. Our findings indicate that quality time, sincere reflection and communication between local experts and potential players, are indispensable when designing a HCG based game. The analysis benefits researchers and practitioners who are interested in the ways in which a game can bridge the gap between people and relevant on-site information"
