Although some forms of distributed groupware now enable fast-paced real-time collaboration (e.g., first-person shooter games), little work has been done to determine how coordination and interaction occur when people attempt to work together at high speed. Understanding the elements of high-speed coordination is important, because shared-workspace groupware systems offer opportunities for new kinds of high-speed work that is, they provide freedom from the physical constraints that can slow and restrict coordination in physical shared spaces. To better understand high-speed coordination, and to examine whether these opportunities can enable new kinds of interaction in groupware, we created and studied a new multi-player game (called RTChess) that is based on traditional chess, but adds multiple players and removes all turns from the gameplay. The result is a free-for-all game where people are limited only by their ability to move quickly and expertly a situation that is more like a team sport than a tabletop game. We carried out an observational study of 448 games of RTChess to look for the emergence of high-speed interaction, team coordination, and interactional expertise. We found that people can interact extremely quickly through distributed groupware, and saw evidence that people build expertise and develop several kinds of coordination in the game. Groupware systems like RTChess indicate that coordination and interaction in shared-workspace collaboration can occur at high speed, and suggest ways to free groupware users from the slow and stilted interactions that are common in many current multi-user systems.

We present results from a case study of the use of business intelligence systems in a human services organization. We characterize four mythologies of business intelligence that informants experience as shared organizational values and are core to their trajectory towards a "culture of data": data-driven, predictive and proactive, shared accountability, and inquisitive. Yet, for each mythology, we also discuss the ways in which being actionable is impeded by a disconnect between the aggregate views of data that allows them to identify areas of focus for decision making and the desired "drill down" views of data that would allow them to understand how to act in a data-driven context. These findings contribute initial empirical evidence for the impact of business intelligence's epistemological biases on organizations and suggest implications for the design of technologies to better support data-driven decision making.

This long-term study analyzes the structure of a technology-mediated local initiative fostering cross-cultural understanding and respect: come_IN intercultural computer clubs provide open yet guided access to modern information and computer technology and offer a space for computer-related collaborative practices of children and adults in intercultural German neighborhoods. Our study addresses problems associated with 'cultural integration' and attempts to solve them through this provision. It reveals rhythms, lifecycles and breakdown situations which, transferred to a general level, form the basic structure for a sustainable implementation of a technology-related local initiative fostering cross-cultural understanding and respect. The study is based on field notes taken in three of these clubs.

Recent research showed that augmented reality (AR) technology is a promising approach to support distributed teams in crime scene investigation. This paper reports on the development and evaluation of a handheld AR system to support team situational awareness and collaboration among co-located and remote forensic investigators. The AR system runs on a smartphone strapped to the wrists of the local investigators and on a laptop for the remote investigator. The AR system has been evaluated with three experienced forensic investigators and was carried out in two rounds: (1) with one local and one remote investigator and (2) with two local and one remote investigator. The evaluation focused on the usability of the AR system and its effect on situational awareness as well as collaboration quality. Compared to earlier experiments using head-mounted devices (HMDs), the findings suggest that the handheld AR system addresses limitations of current HMD based AR system, but the necessary division of attention between smartphone AR system and real environment impacts the situational awareness.

Grounded Theory Method (GTM) and Machine Learning (ML) are often considered to be quite different. In this note, we explore unexpected convergences between these methods. We propose new research directions that can further clarify the relationships between these methods, and that can use those relationships to strengthen our ability to describe our phenomena and develop stronger hybrid theories.

Harassment in online spaces is increasingly part of public debate and concern. Pervasive problems like cyberbullying, hate speech, and the glorification of self-harm have highlighted the breadth and depth of harassment taking place online. In this study we conduct a content analysis of the governing policies for fifteen social media platforms as they relate to harassment (of oneself and/or of community members) and other associated behaviors. We find that there is a striking inconsistency in how platform-specific policies depict harassment. Additionally, how these policies prescribe responses to harassment vary from mild censuring to the involvement of law enforcement. Finally, based on our analysis and findings, we discuss the potential for harnessing the power of the online communities to create norms around problematic behaviors.

Video records are sometimes used during meetings nowadays in order to compensate for the incompleteness of hand-written minutes. To use video effectively to record the minutes of a meeting, indices are considered necessary in addition to standard functions of movie players. Some systems can form indices by sensing human actions in the world, but such indices are not directly relevant to the contents of the discussions that occur in meetings. In this study, we propose an automated meeting index system based on people's discussions during daily meetings in the world. In our system, indices based on the contents of discussion can be automatically formulated in meetings if only paper, writing implements, and a camera are arranged in a certain manner. To this end, we develop trackable sticky notes, called "Tracky Notes," as indices. Tracky Notes can be tracked with visible markers through a camera, and is robust against occlusion. We then propose a meeting viewer where Tracky Notes are used as indices. Finally, we report the result of a user study conducted in a university classroom. The study revealed the appropriate region of visible markers and the robustness against occlusion of Tracky Notes. We also measured the effectiveness of our system comparing with standard functions of movie players.

Research in the field of assistive technologies often claims to support their target group's autonomy. However, autonomy is mostly interpreted by the researchers and designers as independence or its meaning is not further specified. There are few studies where the users' perception and interpretation of autonomy is taken into account. Hence, technology for supporting autonomy is often rather intricate and based on a generalized notion of autonomy. We argue that autonomy contains more dimensions than just mere independence. Furthermore, we argue that the perception of autonomy is individually differing and focussing on small, individual solutions my help in shaping autonomy support on an individual level.

Nodding has various communicative functions in humans, such as agreement, emphasis and turn-taking and can also create various positive impressions in communication by the person exhibiting the behavior. The ultimate aim of our research is to facilitate communication by implementing nodding behavior in robots. This study analyzed videos of human conversations in groups and focused on three aspects of people's nodding behavior as they listened to others: 1) Time period to complete a nodding cycle and each nods, 2) Time delay before initiating a nodding response, and 3) Number of continuous nods used at one time. We found that: 1) The mode time period to a nod was 0.27 s, with 96% of all nods occurring within 0.17~0.57 s. 2) The mode time delay before initiating a nodding response was 0.30 s, with 95% of all nods occurring within -0.78~1.4 s. 3) Fewer than six continuous nods were used 97% of the time - one nod, 55%, two nods, 24%, three nods, 12%, four nods, 3.0%, and five nods, 2.1%. Ultimately, the research findings serve as guidelines for implementing accurate human nodding behavior in robots.
