Contributions from the crowd are not just content-sustainable systems require ongoing behind-the-scenes infrastructural work. In this paper, I explore potential strategies for motivating volunteer contributions to large-scale collaborative projects when volunteer contributions are procedural in nature and largely invisible in the published project. I use a user-driven classification system for a large, established, and growing fanfiction collection as an example of a successful project of this type. I compare the challenges and possibilities to those established in the study of open source, wiki, and citizen science projects, which share with classification design a need for distributed human contributions to procedural tasks. Textual analysis of recruiting and training documents, informed by prolonged engagement in the community, reveals strategies that diverge from other HCI research on motivation, such as a focus on work rather than fun and insider rather than public recognition.

Memory is shaped by the media in which it is communicated (van Dijck, 2007). In a world where people live enmeshed with computing technologies, there are myriad opportunities to enrich and enhance everyday life with new kinds of memory. In my dissertation research, I employ a mixed methods interpretivist approach to investigate how people relate to and revisit memories of their past, how families collectively interact with shared memory, and how pervasive "ubicomp" technologies can be designed to support and enhance the social activities of sharing family memory across generations.

To examine the processes by which appropriation happens around an interactive art installation in an organizational context, this paper presents a qualitative, longitudinal study of an interactive art installation called mood.cloud. While designed to collect and to visually display building occupants' collective emotion, the installation was not necessarily used or interpreted in this way. Instead, building occupants saw the sensory experience of mood.cloud and the ability to change the display as a way to influence their own feelings, the feelings of others, and the overall workplace ambience. We found that interaction with mood.cloud fostered reflection about the relationship between the individual and the larger collective that the person is a part of. This relationship, between appropriation for individual benefit and appropriation for the benefit of others, afforded participants the opportunity to become more aware of their own contribution as part of a larger community. These findings suggest an opportunity to design systems around the interplay between appropriation for the individual and appropriation for the community.

User appropriation can be immensely helpful to bootstrap emerging technologies; but how do new and lesser known technologies attract these earliest adopters? This paper investigates user appropriation of emerging computing technologies, by focusing on Bitcoin, a digital monetary system supported by a peer-to-peer network of computing devices. We conducted in-depth interviews with sixteen Bitcoin community participants in Hong Kong, Singapore, and Baltimore. We describe user appropriation in this case of Bitcoin as a sociocultural journey-from encounter, research and learning, to socialization. We contribute the concept of cultural affinities, including conceptual, contextual and social dimensions, as important mediators leading to early-stage user appropriation.

Group editing is a crucial feature for many end-user applications. It requires high responsiveness, which can be provided only by optimistic replication algorithms, which come in two classes: classical Operational Transformation (OT), or more recent Conflict-Free Replicated Data Types (CRDTs). Typically, CRDTs perform better on downstream operations, i.e., when merging concurrent operations than OT, because the former have logarithmic complexity and the latter quadratic. However, CRDTs are often less responsive, because their upstream complexity is linear. To improve this, this paper proposes to interpose an auxiliary data structure, called the identifier data structure in front of the base CRDT. The identifier structure ensures logarithmic complexity and does not require replication or synchronization. Combined with a block-wise storage approach, this approach improves upstream execution time by several orders of magnitude, with negligeable impact on memory occupation, network bandwidth, and downstream execution performance.

Zoos and museums often rely on interpretive staff, called explainers, to facilitate visitors' learning through conversations and demonstrations. Many explainers begin their careers as teens, and would benefit from ongoing Professional Development (PD). As institutions begin to use mobile devices to enhance explainers' interpretation, new opportunities arise to support explainers' individual and collaborative professional development. This paper presents the results of structured participatory design sessions to engage explainers in examining and proposing features for a Facilitation, Reflection, and Augmented Interpretation Mobile System (FRAIMS). The goal for FRAIMS is to support everyday interpretive tasks while also gathering information on how explainers perform that interpretation (both passively, via logging and recording, and actively, via self-reports and ratings) to support them in their PD. Reflecting on one's own performance and the performance of others is a powerful PD strategy, but can be emotionally fraught. Via participatory design sessions with expert, in-development, and novice explainers at different informal learning institutions, we found that explainers' preferences for socially sharing performance information gathered via mobile devices varied with their experience. We detail emerging themes captured from the sessions and make suggestions for how these findings might apply more broadly to computer-supported professional development systems.

This paper is an introduction to the "Future IKEA Catalogue", enclosed here as an example of a design fiction produced from a long standing industrial-academic collaboration. We introduce the catalogue here by discussing some of our experiences using design fiction` with companies and public sector bodies, giving some background to the catalogue and the collaboration which produced it. We have found design fiction to be a useful tool to support collaboration with industrial partners in research projects - it provides a way of thinking and talking about present day concepts, and present day constraints, without being overly concerned with contemporary challenges, or the requirements of academic validation. In particular, there are two main aspects of this we will discuss here, aspects that are visible in the enclosed catalogue itself. The first is the potential of design fiction as a sort of 'boundary object' in industry and academic collaboration, and second the role of critique. After this introduction to the paper we enclose the output of our collaboration in the form of the catalogue itself.

We conducted a retrospective study on the experimental deployment of a telemedicine toolkit in ten nursing homes. The purpose of the experiment was to see whether the use of these toolkits could allow for better cooperation between nursing homes and the local emergency medical dispatch center to avoid sending costly vehicles and having elderly people unnecessarily discharged at the hospital. We investigated the domestication process of these toolkits by nurses and orderlies from the nursing homes. Our findings show different levels of domestication: for some of the nursing homes, the lack of practical relevance of the toolkit in emergencies and the difficulty to borrow artifacts from doctors prevented complete adoption. For three nursing homes, domestication occurred in an unexpected way in the sense that the objective of the domestication changed. These findings led us to provide recommendations for projects aimed at improving inter-organizational cooperation through artifacts.

Interaction environments are characterized by their spatial properties, which guide, direct, and provide an opportunity to become a place for social encounters. For example, the car cabin comprises properties such as a special seating arrangement and hence physical barriers between the back and front row. In emphasizing notions of "space" and "place", we present an initial study on how such spatial properties of the car cabin shape passenger collaboration. With this, we contribute to a better understanding of the automotive design space beyond driver and co-driver positions. In an exploratory lab study with 56 participants we observed collaborative practices in a hardware mock-up of an actual car. We found that social practices in cars need to be understood as connected to their inherent spatial manifestations, which are constraining and concurrently constituting them. We reflect upon the driver position as "the crux of the matter", the meanings people ascribe to particular positions, and how we can use this knowledge to inform automotive interaction design.

Cloud storage is widely used to share and collaborate on files over the Internet; consistency maintenance of replicated files in the face of concurrency is a major challenge. In this paper, we present a novel CSOT (Cloud Storage Operational Transformation) solution to support real-time file synchronization in front-end cloud storage and achieve consistent and desirable concurrent operation combined-effects that cannot be fully achieved by any existing cloud storage systems. We have formally verified algorithmic correctness of CSOT, built a proof-of-concept implementation, and experimentally compared results produced by CSOT and three industrial cloud storage systems, Microsoft OneDrive, Google Drive, and Dropbox, under the same collection of concurrent operation testing cases. CSOT is the first to extend OT consistency maintenance capability to shared workspaces in cloud storage and contributes to advancement of cloud-based collaboration technologies.
