Group vs Individual: Impact of TOUCH and TILT Cross-Device Interactions on Mixed-Focus Collaboration

論文アブストラクト: Cross-device environments (XDEs) have been developed to support a multitude of collaborative activities. Yet, little is known about how different cross-device interaction techniques impact group collaboration, including how their impact on independent and joint work that often occurs during group work. In this work, we explore the impact of two XDE data browsing techniques: TOUCH and TILT. Through a mixed-methods study of a collaborative sensemaking task, we show that TOUCH and TILT have distinct impacts on how groups accomplish, and shift between, independent and joint work. Finally, we reflect on these findings and how they can more generally inform the design of XDEs.

CommunityCrit: Inviting the Public to Improve and Evaluate Urban Design Ideas through Micro-Activities

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173769

論文アブストラクト: While urban design affects the public, most people do not have the time or expertise to participate in the process. Many online tools solicit public input, yet typically limit interaction to collecting complaints or early-stage ideas. This paper explores how to engage the public in more complex stages of urban design without requiring a significant time commitment. After observing workshops, we designed a system called CommunityCrit that offers micro-activities to engage communities in elaborating and evaluating urban design ideas. Through a four-week deployment, in partnership with a local planning group seeking to redesign a street intersection, CommunityCrit yielded 352 contributions (around 10 minutes per participant). The planning group reported that CommunityCrit provided insights on public perspectives and raised awareness for their project, but noted the importance of setting expectations for the process. People appreciated that the system provided a window into the planning process, empowered them to contribute, and supported diverse levels of skills and availability.

Investigating the Role of an Overview Device in Multi-Device Collaboration

論文URL: http://dl.acm.org/citation.cfm?doid=3173574.3173874

論文アブストラクト: The availability of mobile device ecologies enables new types of ad-hoc co-located decision-making and sensemaking practices in which people find, collect, discuss, and share information. However, little is known about what kind of device configurations are suitable for these types of tasks. This paper contributes new insights into how people use configurations of devices for one representative example task: collaborative co-located trip-planning. We present an empirical study that explores and compares three strategies to use multiple devices: no-overview, overview on own device, and a separate overview device. The results show that the overview facilitated decision- and sensemaking during a collaborative trip-planning task by aiding groups to iterate their itinerary, organize locations and timings efficiently, and discover new insights. Groups shared and discussed more opinions, resulting in more democratic decision-making. Groups provided with a separate overview device engaged more frequently and spent more time in closely-coupled collaboration.
