Nowadays, online games have become a highly profitable e-commerce application. Therefore, researchers increasingly believe that understanding online game player behavior is critical to the success of online game practitioners. The factors influencing the flow of online games are of major concern to academic researchers and online games practitioners. Drawing on the theory of flow, this study em...

To learn, a person has to be able to communicate effectively with others about the knowledge to be learned. Communication processes in class rooms can be supported by Group Support Systems (GSS), that enable students to communicate anonymously and in parallel. GSS experiences suggest that the technology increases observed learning, self-reported learning, on-task participation, and satisfaction...

This paper examines the experiences of players of a problem-solving game. The main purpose of the paper is to validate the flow antecedents included in an experiential gaming model and to study their influence on the flow experience. Additionally, the study aims to operationalize the flow construct in a game context and to start a scale development process for assessing the experience of flow i...

.......Competition between platforms generates vendor behavior that sometimes aligns with the interests of users and application developers, and sometimes does not. For example, competition gives platform leaders incentives to improve the functionality of their code and improve the experiences of their users. It also leads them to make it difficult for users and programmers to switch between pl...

Echocardiography is a widely used imaging technique to examine various cardiac functions, especially to detect the left ventricular wall motion abnormality. Unfortunately the quality of echocardiograph images and complexities of underlying motion captured, makes it difficult for an inexperienced physicians/ radiologist to describe the motion abnormalities in a crisp way, leading to possible err...

Data mining-driven agents are often used in applications such as waiting times estimation or traffic flow prediction. Such approaches often require large amounts of data from multiple sources, which may be difficult to obtain and lead to incomplete or noisy datasets. University ID card data, in contrast, is easy to access with very low noise. However, little attention has been paid to the avail...

The measurement of subjective playing experience is an important part of a game development process. The enjoyment level that a serious game offers is a key factor in determining whether a player will be engaged in a gameplay and achieve the specific objectives of the game, such as learning. In this paper, we report the results of a game design process in which two prototypes of a collaborative...

In this position paper we identify and discuss design issues involved in future nutrigenomics and nutrigenetics interfaces and services based on connecting heterogeneous data from food flows (farm to fork) to food consumption and body interaction of nutrients with DNA, microbiome etc. How to connect data from farm to fork to phenotype and what type of user experiences these data enable? What sh...

Realistic and accurate packet loss measurement of production traffic has been challenging, since the frequently-used active monitoring approaches using probe packets cannot capture the packet loss experienced by the traffic of individual user applications. In this paper, we present a new approach for the accurate measurement of the packet loss rate faced by actual production traffic based on pa...
