    Exploring How a Co-Dependent Tangible Tool Design Supports Collaboration in a Tabletop Activity
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Fan, Min; Antle, Alissa N.; Neustaedter, Carman; Wise, Alyssa F.
    Many studies suggest that tangibles and digital tabletops have potential to support collaborative interaction. However, previous findings show that users often work in parallel with such systems. One design strategy that may encourage collaboration rather than parallel use involves creating a system that responds to co-dependent access points in which more than one action is required to create a successful system response. To better understand how co-dependent access points support collaboration, we designed a comparative study with 12 young adults using the same application with a co-dependent and an independent access point design. We collected and analyzed categories of both verbal and behavioural data in the two conditions. Our results show support for the co-dependent strategy and suggest ways that the co-dependent design can be used to support flexible collaboration on tangible tabletops for young adults.

    Designing Better Location Fields in User Profiles
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Wang, Ting-Yu; Harper, F. Maxwell; Hecht, Brent
    Twitter, Facebook, Pinterest and many other online communities ask their users to populate a location field in their user profiles. The information that is entered into this field has many uses in both industry and academia, with location field data providing valuable geographic context for operators of online communities and playing key roles in numerous research projects. However, despite the importance of location field entries, we know little about how to design location fields effectively. In this paper, we report the results of the first controlled study of the design of location fields in user profiles. After presenting a survey of location field design decisions in use across many online communities, we show that certain design decisions can lead to more granular location information or a higher percentage of users that fill out the field, but that there is a trade-off between granularity and the percent of non-empty fields. We also add context to previous work that found that location fields tend to have a high rate of non-geographic information (e.g. Location: Justin Bieber's Heart"), showing that this result may be site-specific rather than endemic to all location fields. Finally, we provide evidence that verifying users' location field entries against a database of known-valid locations can eliminate toponym (place name) ambiguity and any non-geographic location field entries while at the same time having little effect on field population rate and granularity."

    Investigating the Use of a Simulator to Support Users in Anticipating Impact of Privacy Settings in Facebook
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Junior, Manoel Pereira; Xavier, Simone Isabela de Rezende; Prates, Raquel Oliveira
    One of the challenges faced by Facebook users is that privacy settings change not only the visibility of the information, but also impact actions other users can take on a piece of information. These actions on their turn can also create changes to the visibility of that piece of information, sometimes granting access to people originally unintended by the user who posted the information. In this paper we investigate how a simulator that allows users to explore the different situations that can result from privacy settings may support them in anticipating the impact of their decisions. To do so, we have implemented a privacy setting simulator prototype, and evaluated it through a qualitative case-study which involved 12 regular Facebook users. Our findings indicate that the simulator improved users understanding of the effects of their privacy settings and allowed them to identify misunderstandings they had about the visibility of their information.

    If It Is Funny, It Is Mean: Understanding Social Perceptions of Yelp Online Reviews
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Bakhshi, Saeideh; Kanuparthy, Partha; Shamma, David A.
    Online recommendation communities, like Yelp, are valuable information sources for people. Yet, we assert, review communities have their own dynamics behind the social interactions therein. In this work, we study the Yelp review votes of useful, funny, and/or cool to understand these social perceptions of the review. We examine the relationship between these social signals and the emotional valence of the review itself (text and rating). We aim to understand the community's perception of each of these signaling contributions. We construct a conditional inference tree of social signals from 230K Yelp reviews to study how social signals shape the deviance in review rating from the mean rating, an indicator of the overall business rating on Yelp. We find two effects of social signals. First, reviews voted as useful and funny are associated with lower user ratings and relatively negative tone in the review text. Second, reviews voted as cool tend to have a relatively positive tone and higher ratings. Our findings open a research direction for further understanding of perceptions of social signals and have implications for design of recommendation systems.

    Impression Management Struggles in Online Dating
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Zytko, Douglas; Grandhi, Sukeshini A.; Jones, Quentin
    Online dating systems are now widely used to search for romance and yet there is little research on how people use these systems to manage their impressions with potential romantic partners. To address this issue we conducted an interview study of 41 online dating users, revealing that-contrary to prior work-online daters largely do not want to intentionally deceive their online dating partners because they think such lies would quickly be discovered face-to-face. Nevertheless, bad first dates were a norm rather than an exception for this study's participants. In this paper we present various frustrations online daters associate with conveying and forming impressions of potential romantic partners before meeting face-to-face. We discuss the implications of these findings for the design of online dating systems.

    Collaboration and Coordination in the Context of Informal Care (CCCiC): Concepts, Methods, and Technologies
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Tellioğlu, Hilda; Lewkowicz, Myriam; Pinatti De Carvalho, Aparecido Fabiano; Brešković, Ivan; Schinkinger, Susanne; Tixier, Matthieu
    Increasing attention is currently paid to informal care and the physical, emotional, and psychological burden stemming from it. Research findings suggest that such a burden might be intensified when informal caregivers are at older ages. Aiming at reducing the burden associated with informal care, some research studies have focused on developing innovative technologies to support caregivers with their activities and responsibilities. These studies highlight the importance of understanding the many variables that characterise different care situations, emphasizing the relevance of user-centered and participatory design approaches. Following up the successful first edition of the CCCiC workshop held at the 2014 ACM CSCW conference in Baltimore, this workshop elaborates on the resulting roadmap for future research in the domain: concepts, methods, and technologies. This workshop seeks contributions exploring issues of collaboration and coordination for informal care addressing concepts emerging from field research, methodological challenges, work-in-progress, and the design and evaluation of technological solutions.

    Potentials of the Unexpected: Technology Appropriation Practices and Communication Needs
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Tscheligi, Manfred; Krischkowsky, Alina; Neureiter, Katja; Inkpen, Kori; Muller, Michael; Stevens, Gunnar
    Whether in private or professional life, individuals frequently adapt the technology around them and work with what they have at hand to accomplish a certain task. In this one-day workshop, we will discuss how this form of technology appropriation is used to satisfy communication needs. Thereby, we specifically focus on technology that was not intended to facilitate communication, but which led to appropriation driven by individuals' communication needs. Our aim is to identify unexpected" communication needs, to better address these in the design of interactive systems. We focus on a variety of different contexts, ranging from not restricted contexts to environments that are characterized by strict regulations (e.g., production lines with 24/7 shift production cycles). Consequently, this workshop aims at better understanding how users adapt technology to match their individual communication purposes and how these appropriation practices interrelate with and support organizational cooperation."

    The Morphing Organization: Rethinking Groupwork Systems in the Era of Crowdwork
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Anya, Obinna; Carletti, Laura; Coughlan, Tim; Hansson, Karin; Liu, Sophia B.
    Web 2.0 has provided organizations remarkable opportunities to improve productivity, gain competitive advantage, and increase participation by engaging a crowd to accomplish tasks at scale. However, establishing and integrating crowd-based systems into organizations is still an open question. The systems and the collaborative processes they enable appear diametrically in dissonance with the norms and culture of collaboration and knowledge sharing in traditional organizations. They require mechanisms for articulation of work, coordination, cooperation, and knowledge co-creation that are fundamentally different from those in current groupwork systems and processes. Building on two workshops hosted at ACM CSCW 2014, we will explore questions such as: How does the shift in organizational work from a closed system with known individuals, to an open and crowd model that requires engagement with an undefined network of people, affect how we conceptualize groupwork? What are the implications for the design of groupwork systems? What can the crowdsourcing research community learn from groupwork systems, or conversely what can groupwork researchers learn from crowdsourcing? How do cultures, motivations, ownership and representation fit into these systems? This workshop will bring together researchers and practitioners in crowdsourcing, social computing, collaborative technologies, organizational science, and workplace research, to discuss the future of groupwork systems in the era of crowdwork with the goal of articulating an agenda for future research.

    Evaluating Mobile Remote Presence (MRP) Robots
    (Proceedings of the 2014 ACM International Conference on Supporting Group Work, 2014) Lewis, Tristan; Drury, Jill; Beltz, Brandon
    Video teleconferencing systems (VTCs) have enhanced remote meetings because their ability to convey nonverbal or social cues can make them simulate in-person interaction more closely than telephone conversations. Yet many people feel that something is still lacking, most likely because VTCs require all interaction to take place in a pre-defined set of rooms and/or from a single viewpoint. In contrast, mobile remote presence (MRP) robots, sometimes called telepresence robots, enable participants to move their focus from their colleagues' faces to a screen at the front of the room, to artifacts on a table, to posters or sticky notes on the room's walls, etc. Consumers now have a choice of several commercially available MRP systems, but there are few evaluation methods tailored for this type of system. In this paper we present a proposed set of heuristics for evaluating the user experience of a MRP robot. Further, we describe the process we used to develop these heuristics.
