Online freelancing platforms, such as Upwork, hold great promise in enabling flexible work opportunities where freelancers can combine their work with other life responsibilities, hereafter work-life. However, prior research suggests that platform features and self-managing demands of freelance work can jeopardise this apparent flexibility. In this paper, we report findings from a qualitative study, combining a 14-diary and semi-structured interview with 15 Upwork freelancers. We explored online freelancers' work practices, challenges, and the impact of platform features on their everyday lives. Our qualitative data suggest that platform features and individual context shape online freelancers' work-life practices. Freelancers develop strategies to mitigate platforms' constraints and balance their individual preferences and responsibilities. Further, our findings illustrate how platform features challenge freelancers' availability expectations, work autonomy, and work detachment. This paper contributes an empirical understanding of the factors influencing online freelancers' work-life practices by drawing upon Wanda J. Orlikowski's Structuration Model of Technology. This theoretical lens renders the interplay of freelancers, platforms, and instituted norms of freelance work.

Freelancing platforms, such as Upwork, represent an expansion of the gig economy to encompass knowledge-based work. Prior research in HCI has primarily focused on forms of gig work such as ride-sharing and microwork but has not addressed how freelancing platforms are disrupting high-skilled knowledge work. To understand freelancers’ perspectives on how these platforms are disrupting their work we have collected and thematically analysed 528 posts with 7499 comments from four relevant subforums on Reddit. The qualitative findings reveal tensions between wanting autonomy and control and the necessity of opportunities and convenience. Freelancing platforms are perceived as systems that present advantages to find clients, gain experience and mitigate precarity. However, these platforms constrain the control over their work that freelancers value. The paper contributes an improved understanding of freelance work, the role and potential for freelancing platforms in the knowledge-based gig economy, and directions for worker-centred design.

Many men stop exercising as they age, engage in risky behaviours such as alcohol misuse, are reluctant to admit to mental health problems, and avoid seeking help. Men are generally hard to reach for community health interventions. However, interventions run at football clubs have successfully engaged men and have led to positive health outcomes. Mobile health technology might similarly be designed to engage and encourage men via connections with football. This technology could be used to augment and extend community programs, or be used to target global fan bases. However, it is not clear if and how what attracts men to community interventions can translate to technology. In this paper we report a design study with 18 middle-age male participants exploring what men find important in football, and connections between football, health and technology. We present five design opportunities to guide and prompt further innovation in this area.

There is a mental health crisis facing universities internationally. A growing body of interdisciplinary research has successfully demonstrated that using sensor and interaction data from students' smartphones can give insight into stress, depression, mood, suicide risk and more. The approach, which is sometimes termed Digital Phenotyping, has potential to transform how mental health and wellbeing can be monitored and understood. The approach could also transform how interventions are designed, delivered and evaluated. To date, little work has addressed the human and ethical side of digital phenotyping, including how students feel about being monitored. In this paper we report findings from in-depth focus groups, prototyping and interviews with students. We find they are positive about mental health technology, but also that there are multi-layered issues to address if digital phenotyping is to become acceptable. Using an acceptability framework, we set out the key design challenges that need to be addressed.

We have created and evaluated a novel mobile messaging app named Curtains Messenger. The app has been designed to support synchrony in messaging. It does this by requiring users to be in the app at the same time as each other in order to send, receive and read messages. This design is contrary to typical apps where messages can be sent and read asynchronously at an individual's convenience. We have conducted a field trial in which 15 users installed the app on their own devices and used it in the wild. We present a qualitative analysis of interviews with the participants following the trial. The findings address how the app was used, how synchrony affected conversational flows, how synchrony raised issues of attention and intimacy, and what issues users faced in the practical work of conducting synchronous messaging. This work demonstrates how core concepts in the study of cooperative work such as a/synchrony can be drawn upon to reconsider taken-for-granted design features of mobile applications and the lived experience of communication.

Numerous studies have tracked people's everyday use of digital devices, but without consideration of how such data might be of personal interest to the user. We have developed a personal tracking application that enables users to automatically monitor their 'screen time' on mobile devices (iOS and Android) and computers (Mac and Windows). The application interface enables users to combine screen time data from multiple devices. We trialled the application for 28+ days with 21 users, collecting log data and interviewing each user. We found that there is interest in personal tracking in this area, but that the study participants were less interested in quantifying their overall screen time than in gaining data about their use of specific devices and applications. We found that personal tracking of device use is desirable for goals including: increasing productivity, disciplining device use, and cutting down on use.

We have developed a mobile application called Pass The Ball that enables users to track, reflect on, and discuss physical activity with others. We followed an iterative design process, trialling a first version of the app with 20 people and a second version with 31. The trials were conducted in the wild, on users' own devices. The second version of the app enforced a turn-taking system that meant only one member of a group of users could track their activity at any one time. This constrained tracking at the individual level, but more successfully led users to communicate and interact with each other. We discuss the second trial with reference to two concepts: social-relatedness and individual-competence. We discuss six key lessons from the trial, and identify two high-level design implications: attend to "practices" of tracking; and look within and beyond "collaboration" and "competition" in the design of activity trackers.

This paper characterises the use of activity trackers as "lived informatics". This characterisation is contrasted with other discussions of personal informatics and the quantified self. The paper reports an interview study with activity tracker users. The study found: people do not logically organise, but interweave various activity trackers, sometimes with ostensibly the same functionality; that tracking is often social and collaborative rather than personal; that there are different styles of tracking, including goal driven tracking and documentary tracking; and that tracking information is often used and interpreted with reference to daily or short term goals and decision making. We suggest there will be difficulties in personal informatics if we ignore the way that personal tracking is enmeshed with everyday life and people's outlook on their future.

This paper discusses a repetition of a study presented in Suchman's book Plans and Situated Actions. There have been complaints about the lack of replication studies in disciplines related to CSCW (particularly Software Engineering and HCI). However, these complaints often become embedded in wider attempts to install a principled scientific method within these disciplines. Plans and Situated Actions was not a scientific text but drew upon naturalistic analysis. This paper shows there is value in recreating Plans and Situated Actions, and argues it would be helpful to recreate other studies. However, such repetition does not and need not constitute a scientific replication. The paper argues that while repetition and reanalysis may improve rigour in computing research, this need not be with a view to making it more scientific.

Suchman’s book Plans and Situated Actions has been influential in HCI (Human Computer Interaction). The book is often discussed with reference to ethnographic fieldwork, sometimes being cited as if it were a field study. However, the book uses examples from a laboratory study and contains criticisms of ethnography. This article explores how and why Suchman carried out a laboratory study. Based upon this exploration, it argues that social analysis in HCI does not necessitate fieldwork outside the laboratory. More broadly, the paper argues that an appreciation of Plans and Situated Actions can help in moving towards forms of social analysis that span both the laboratory and the world outside. If there is to be a “turn to the wild” in HCI, this should not be a turn away from the laboratory but a turn away from research methods that ignore human practice. This is not to defend laboratory experiments, but to defend laboratory-based studies that explicate technology in practice.

As systems scale, systems management often becomes partially reliant on web forums and other social media. This paper examines the use of web forums for diagnostic work in cloud computing. We argue that forums are not simply used to communicate information but that (with users attempting to negotiate and manage the attention of providers, forming coalitions, criticizing others, and framing problems in particular ways) forums are socially organised, value laden venues for information. We conclude that providers should focus not on improving communication, but more broadly on managing community.

This paper examines how software developers discuss users and how such discussions are intrinsic to the negotiation and settling of technical decisions in the development and testing of a software product. Using ethnographic data, we show how the user features in conversations, not as a 'topic' but as 'context' to technical work. By understanding the user as a contextual feature in developers' group work we are able to draw attention to issues in the use of Extreme Programming for software product development. Extreme Programming is a participatory design method, but software product development involves envisioning and designing for future customers.

In this paper we report on an ethnographic study of a small software house to discuss the practical work of software testing. Through use of two rich descriptions, we discuss that 'rigour' in systems integration testing necessarily has to be organisationally defined. Getting requirements 'right', defining 'good' test scenarios and ensuring 'proper' test coverage are activities that need to be pragmatically achieved taking account of organisational realities and constraints such as: the dynamics of customer relationships; using limited effort in an effective way; timing software releases; and creating a market. We discuss how these organisational realities shape (1) requirements testing; (2) test coverage; (3) test automation; and (4) test scenario design.
