“…Installations comprised dedicated devices and hardware that just displayed the video link (in contrast to a workstation that would be used for various purposes). Second, many media spaces were designed to provide connections between workplace offices or cubicles [Coutaz et al 1998, Mantei et al 1991, Dourish 1993, Dourish et al 1996, Greenberg and Rounding 2001, McEwan and Greenberg 2005. For example, CAVECAT connected multiple co-workers' offices with always-on video, mostly of each person working at his or her desk [Mantei et al 1991].…”

Video chat systems such as Skype, Google+ Hangouts, and FaceTime have been widely adopted by family members and friends to connect with one another over distance. We have conducted a corpus of studies that explore how various demographics make use of such video chat systems where this usage moves beyond the paradigm of conversational support to one in which aspects of everyday life are shared over long periods of time, sometimes in an almost passive manner. We describe and reflect on studies of longdistance couples, teenagers, and major life events, along with design research focused on new video communication systems-the Family Window, Family Portals, and Perch-that explicitly support 'alwayson video' for awareness and communication. Overall, our findings show that people highly value long-term video connections and have appropriated them in a number of different ways. Designers of future video communication systems need to consider: ways of supporting the sharing of everyday life, rather than just conversation; providing different design solutions for different locations and situations; providing appropriate audio control and feedback; and, supporting expressions of intimacy over distance.

“…sensitive details in video while still providing a low-fidelity overview useful for awareness [Zhao and Stasko 1998;Boyle et al 2000]. Publication filters, such as the background subtraction filter in Figure 1, remove details considered unimportant for awareness information [Coutaz et al 1998;Junestrand et al 2001]. Finally, potentially privacy-threatening details can be abstracted away from the video altogether such as in instant messenger status icons and in the eigenspace filter in Figure 1 [Crowley et al 2000].…”

Video media spaces are an excellent crucible for the study of privacy. Their design affords opportunities for misuse, prompts ethical questions, and engenders grave concerns from both users and nonusers. Despite considerable discussion of the privacy problems uncovered in prior work, questions remain as to how to design a privacy-preserving video media space and how to evaluate its effect on privacy. The problem is more deeply rooted than this, however. Privacy is an enormous concept from which a large vocabulary of terms emerges. Disambiguating the meanings of and relationships between these terms facilitates understanding of the link between privacy and design. In this article, we draw from resources in environmental psychology and computersupported cooperative work (CSCW) to build a broadly and deeply rooted vocabulary for privacy. We relate the vocabulary back to the real and hard problem of designing privacy-preserving video media spaces. In doing so, we facilitate analysis of the privacy-design relationship. enthusiastic about the technology yet well aware of its potential for sociological and psychological impact. This combination of participants and problems makes video media spaces an excellent crucible for examining the privacy-design link. For example, it is the application area in which Bellotti applies her framework for privacy in CSCW and CMC [Bellotti 1998]. Approaches to Privacy ResearchResearchers in CSCW generally assume that privacy problems caused by technology arise because of the way systems are designed, implemented, and deployed. For example, Grudin suggests that the underlying drive to increase human efficiency through technology-specifically context-aware systemsleads to design decisions that conflict with privacy [Grudin 2001]. This argument applies equally to video media spaces.Although there is now a reasonable body of literature that discusses the design problems found in video media spaces, the emphasis thus far has been on generalizing about the symptoms observed and then proposing specific countermeasures-point solutions-to offset specific symptoms. Although there has been excellent empirical discussion of the human and technical factors that prompt privacy problems [e.g., Bellotti 1998], not all factors are discussed nor are these factors related to one another in a cohesive fashion nor do they completely account for all problems observed. Technocentric bottom-up approaches do not readily yield insight into how to diagnose privacy problems and predict when they will occur, or provide an intellectual foundation from which to generate new kinds of solutions. Grudin [2001] compares "bottom-up" versus "top-down" methods for exploring privacy-design issues. He suggests that while bottom-up approaches readily address technical issues, they demand trial and error to address social issues and are thus too slow and unethical to use for problems like privacy.Recently, several researchers have begun top-down examinations of privacyand-design that integrate CSCW findings with theories devel...

“…The media space concept originated at Xerox-PARC in the early 1980s as prototype systems for fostering workplace collaboration. Most resulting and subsequent research [3][4][5][6] has examined the uses and reactions to video communication in the workplace, and the extension of these findings to domestic settings is questionable given the differences in expectations and behavior that typify the work and home environments. As a first example, a media space controls for home users.…”

Automated videography for residential communications

The current widespread use of webcams for personal video communication over the Internet suggests that opportunities exist to develop video communications systems optimized for domestic use. We discuss both prior and existing technologies, and the results of user studies that indicate potential needs and expectations for people relative to personal video communications. In particular, users anticipate an easily used, high image quality video system, which enables multitasking communications during the course of real-world activities and provides appropriate privacy controls. To address these needs, we propose a potential approach premised on automated capture of user activity. We then describe a method that adapts cinematography principles, with a dual-camera videography system, to automatically control image capture relative to user activity, using semantic or activity-based cues to determine user position and motion. In particular, we discuss an approach to automatically manage shot framing, shot selection, and shot transitions, with respect to one or more local users engaged in real-time, unscripted events, while transmitting the resulting video to a remote viewer. The goal is to tightly frame subjects (to provide more detail), while minimizing subject loss and repeated abrupt shot framing changes in the images as perceived by a remote viewer. We also discuss some aspects of the system and related technologies that we have experimented with thus far. In summary, the method enables users to participate in interactive video-mediated communications while engaged in other activities.
