Online social networking communities such as Facebook and MySpace are extremely popular. These sites have changed how many people develop and maintain relationships through posting and sharing personal information. The amount and depth of these personal disclosures have raised concerns regarding online privacy. We expand upon previous research on users'(More)
In this paper, we address the design issues of a collaborative workspace system, called TeamSpace, that supports geographically distributed teams by managing shared work processes and maintaining shared artifacts in a project. TeamSpace attempts to integrate both synchronous and asynchronous types of team interaction into a task-oriented environment. Since(More)
Multimedia records of meetings contain a rich amount of project information. However, finding detailed information in a meeting record can be difficult because there is no structural information other than time to aid navigation. In this paper we survey and discuss various ways of indexing meeting records by categorizing existing approaches along multiple(More)
Many social network sites, such as Facebook and MySpace, feature social applications, applications and services written by third party developers that provide additional functionality linked to a user's profile. Current platforms allow these applications to consume much of a user's profile information, as well as the profile information of the user's(More)
Users of online social networking communities are disclosing large amounts of personal information, putting themselves at a variety of risks. Our ongoing research investigates mechanisms for socially appropriate privacy management in online social networking communities. As a first step, we are examining the role of interface usability in current privacy(More)
Meeting capture has been a common subject of research in the ubiquitous computing community for the past decade. However, the majority of the research has focused on technologies to support the capture but not enough on the motivation for accessing the captured record and the impact on everyday work practices based on extended authentic use of a working(More)
Photo tagging is a popular feature of many social network sites that allows users to annotate uploaded images with those who are in them, explicitly linking the photo to each person's profile. In this paper, we examine privacy concerns and mechanisms surrounding these tagged images. Using a focus group, we explored the needs and concerns of users, resulting(More)
This paper presents Game2Learn, an innovative project designed to leverage games in retaining students in computer science (CS). In our two-pronged approach, students in integrative final-year capstone courses and summer research experiences develop games to teach computer science, which, in turn, will be used to improve introductory computing courses. Our(More)
The polularity of social networking websites such as Facebook and the subsequent levels and depth of online disclosures have raised several concerns for user privacy. Previous research into these sites has indicated the importance of disclosures between users as well as an under-utilization of extensive privacy options. This study qualitatively examines(More)
Social navigation is a promising approach to help users make better privacy and security decisions using community knowledge and expertise. Social navigation has recently been applied to several privacy and security systems such as peer-to-peer file sharing, cookie management, and firewalls. However, little empirical evaluation of social navigation cues has(More)
