Pervasive games are an emerging new game genre, which includes context information as an integral part of the game. These games differ from traditional games in that they expand spatio-temporal and social aspects of gaming. Mobile devices support this by enabling players to choose when and where a game is played. Designing pervasive games can be a challenging task, since

Larger display surfaces are becoming increasingly available due to multi-monitor capability built into many systems, in addition to the rapid decrease in their costs. However, little is known about the performance benefits of using these larger surfaces compared to traditional single-monitor displays. In addition, it is not clear that current software designs and interaction techniques have been properly tuned for
We present and compare two approaches to the task of summarizing evaluative ar- guments. The first is a sentence extraction- based approach while the second is a lan- guage generation-based approach. We evaluate these approaches in a user... more
We present and compare two approaches to the task of summarizing evaluative ar- guments. The first is a sentence extraction- based approach while the second is a lan- guage generation-based approach. We evaluate these approaches in a user study and find that they quantitatively perform equally well. Qualitatively, however, we find that they perform well for different but complementary reasons.

Micro-incentives represent a new but little-studied trend in participant compensation for user studies. In this paper, we use a combination of statistical analysis and models from labor economics to evaluate three canonical micro-payment schemes in the context of high-burden user studies, where participants wear sensors for extended durations. We look at how these strategies affect compliance, data quality, and retention, and show that when used carefully, micro-payments can be highly beneficial. We find that data quality is ...

This paper describes a user study regarding the human need to stay in touch with closely related people. The study was a combination of interviews and diaries. This user needs analysis has informed the design of a novel end-to-end communication system for helping closely related people, who are spread geographically, to stay in touch. The design concept is described in brief, followed by a summary of ongoing implementation and assessment work.

Abstract. The goal of this study was to gain insight into the user experience of a recent hypernarrative interactive movie. Turbulence is a feature-length interactive narrative video and emphasising low frequency interaction, simultaneous optional plotlines and seemingly counter-agency moves. Eight participants took part in a phenomenological study of their experience, from which several directions for further study emerge.

Scholars of political socialization are paying increasing attention to how the Internet might help cure the civic disengagement of youth. This content analysis of a sample of 73 U.S.-based civic Web sites for youth introduces a framework for evaluating Web sites' strategies for fostering active communication for citizenship. We offer the first systematic assessment of the extent to which a broad range of Web sites aim to develop young people's abilities to use information and communication technology (ICT) as a vehicle for civic participation and to engage with ICT as a policy domain that encompasses issues (such as freedom of speech and intellectual property rights) that shape the conditions for popular sovereignty online. The study finds low levels of interactive features (such as message boards) that allow young people to share editorial control by offering their own content. In addition, few sites employ active pedagogical techniques (such as simulations) that research suggests are most effective at developing civic knowledge, skills, and participation. We also find little attention to ICT policy issues, which could engage budding citizens in debates over the formative conditions for political communication in the information age. We conclude with suggestions for civic Web site designers and hypotheses for user studies to test.

Text-based passwords remain the dominant authentication method in computer systems, despite significant advancement in attackers' capabilities to perform password cracking. In response to this threat, password composition policies have grown increasingly complex. However, there is insufficient research defining metrics to characterize password strength and using them to evaluate password-composition policies. In this paper, we analyze 12,000 passwords collected under seven composition policies via an online study ...

The major purpose of this study was to examine the Information Seeking Behavior of Dr Babasaheb Ambedkar marathwada university Aurangabad. Information seeking behavior is expressed in various forms, from reading printed material to research and experimentation. Informationseeking behavior Play the vital role for developing library collections, upgrading facilities, and improving services to effectively meet the information needs of users. The present era is an era of information and knowledge revolution. Many electronic resources have been made most available in the libraries. The increase in availability of information on the Web has affected Information seeking behavior
