Bipartite electronic SLA as a business framework to support cross-organization load management of real-time online applications

Online applications such as games and e-learning applications fall within the broader category of real-time online interactive applications (ROIA), a new class of ‘killer’ application for the Grid that is being investigated in the edutain@grid project. The two case studies in edutain@grid are an online game and an e-learning training application. We present a novel Grid-based business framework that makes use of bipartite service level agreements (SLAs) and dynamic invoice models to model complex business relationships in a massively scalable and flexible way. We support cross-organization load management at the business level, through zone migration. For evaluation we look at existing and extended value chains, the quality of service (QoS) metrics measured and the dynamic invoice models that support this work. We examine the causal links from customer quality of experience (QoE) and service provider quality of business (QoBiz) through to measured quality of service. Finally we discuss a shared reward business ecosystem and suggest how extended service level agreements and invoice models can support this

Optimal configuration of active and backup servers for augmented reality cooperative games

Interactive applications as online games and mobile devices have become more and more popular in recent years. From their combination, new and interesting cooperative services could be generated. For instance, gamers endowed with Augmented Reality (AR) visors connected as wireless nodes in an ad-hoc network, can interact with each other while immersed in the game. To enable this vision, we discuss here a hybrid architecture enabling game play in ad-hoc mode instead of the traditional client-server setting. In our architecture, one of the player nodes also acts as the server of the game, whereas other backup server nodes are ready to become active servers in case of disconnection of the network i.e. due to low energy level of the currently active server. This allows to have a longer gaming session before incurring in disconnections or energy exhaustion. In this context, the server election strategy with the aim of maximizing network lifetime is not so straightforward. To this end, we have hence analyzed this issue through a Mixed Integer Linear Programming (MILP) model and both numerical and simulation-based analysis shows that the backup servers solution fulfills its design objective

Social gaming: A systematic review

Digital games often constitute a shared activity where people can spend time together, communicate and socialize. Several commercial titles place social interaction at the center of their design. Prior works have investigated the social outcomes of gaming, and factors that impact the experience. Yet, we lack a comprehensive understanding of how social gaming has been approached and explored before. In this work, we present a systematic review covering 263 publications, gathered in February 2021, that study gaming experiences involving more than one person, with a focus on the social element that emerges among partakers (players and/or spectators). We contribute with a systematized understanding of (1) how the topic is being defined and approached, (2) what facets (mainly in terms of outcomes and determinants of the experience) are being acknowledged and (3) the methodologies leveraged to examine these. Our analysis, based on mixed deductive and inductive coding, reveals relevant gaps and tendencies, including (1) the emphasis in novel technologies and unconventional games, (2) the apparent negligence of player diversity, and (3) lower ecological validity associated with totally mediated evaluations and a lack of established constructs to assess social outcomes

Media Specialists and Gaming

The purpose of this portfolio is to provide three games that a media specialist can use to help bring play to education and to enhance a student’s education. The media center should be an ever adapting environment and a place to provide students and teachers with new materials and ideas that fit their needs. Media specialists are in an excellent position to introduce digital games and collaborate with other educators and while doing this add more play to a testing and standard focused curriculum. The research in this portfolio will look to see how play and games are affecting education and what types of games are being used in the Media Center and in classrooms. This information will be used to inform the creation of three games a media specialist can use to enhance a child’s experience and education in the school. The first game, developed by the author, will provide students with fun and educational materials that can be used in and outside the classroom and help teachers differentiate instruction for their students. The second game, also developed by the author, will motivate and encourage students to read for enjoyment. The third project provides materials to integrate an existing game that teachers can use in any subject’s curriculum as a form of formative assessment and to help students work on the 4Cs

Use of Cloud Gaming in Education

The use of digital games in education has been the subject of research for many years and their usefulness has been confirmed by many studies and research projects. Standardized tests, such as PISA test, show that respondents achieved better reading, math and physics results if they used the computer more for gaming-related activities. It has been proven that the application of video games in education increases student motivation, improves several types of key skills—social and intellectual skills, reflexes and concentration. Nevertheless, there are several challenges associated with the application of video games in schools and they can be categorized as technical (network and end device limitations), competency (teachers’ knowledge in the area), qualitative (lack of educational games of high quality), and financial (high cost of purchasing games and equipment). The novel architecture for delivery of gaming content commonly referred to as “cloud gaming” has the potential to solve most of the present challenges of using games in education. A well-designed cloud gaming platform would enable seamless and simple usage for both students and teachers. While solving most of the present problems, cloud gaming introduces a set of new research challenges which will be discussed in this section

An architecture for integrating learning object repository resources into web videoconference services

Reusing Learning Objects saves time and reduce development costs. Hence, achieving their interoperability in multiple contexts is essential when creating a Learning Object Repository. On the other hand, novel web videoconference services are available due to technological advancements. Several benefits can be gained by integrating Learning Objects into these services. For instance, they can allow sharing, co-viewing and synchronized co-browsing of these resources at the same time that provide real time communication. However, several efforts need to be undertaken to achieve the interoperability with these systems. In this paper, we propose a model to integrate the resources of the Learning Object Repositories into web videoconference services. The experience of applying this model in a real e-Learning scenario achieving interoperability with two different web videoconference services is also described
