DisQo : A user needs analysis method for smart home

International audienceHow can people identify the services that they might expect from their smart home when they have little to no knowledge about novel technologies? This paper reports on a user needs analysis method designed to answer this question: DisQo. We have recruited 17 families and used a combination of interviews and playful cultural probes. Results show that families are willing to couple smart objects to improve their lives

User agency as a feminist frame in human computer interaction and information science

User agency within sociotechnical contexts supports both feminist reflexivity in HCI research, and the feminist ethnographic tradition present within Information Science. User agency as a unifying scholarly frame between these two disciplines that in turn expand our understanding of gender identity formation within information and computing environments

Putting the gender back in digital housekeeping

Prior work examining technology usage and maintenance practices in homes describes division of labor in terms of technical expertise. In this paper, we offer a counter-narrative to this explanation for engagement with Ubiquitous Computing. Using feminist theory as an analytic lens, we examine how gender identity work is a determining factor of whether and how people engage with digital technologies in their homes. We present a model of gender & technical identity co-construction

Software, objects and home space (NIRSA) Working Paper Series. No. 35

Through a series of interrelated developments, software is imbuing everyday objects with capacities that allow them to do additional and new types of work. On the one hand, objects are remade and recast through interconnecting circuits of software that makes them machine-readable. On the other, objects are gaining calculative capacities and awareness of their environment that allow them to conduct their own work, with only intermittent human oversight, as part of diverse actant-networks. In the first part of the paper we examine the relationship between objects and software in detail, constructing a taxonomy of new types of coded objects. In the second part we explore how the technicity of coded objects is mobilised to transduce space by considering the various ways in which coded objects are reshaping home life in different domestic spaces

Systemic Design for the innovation of home appliances The meaningfulness of data in designing sustainable systems

This work addressed the domestic environment considering this context as a complex system characterised by significant impacts in terms of resource consumption. Within the theoretical framework of Systemic Design (SD), this thesis focused on home appliances, in order to understand how to reduce the impact directly attributable to them, while optimising and simplifying daily tasks for the user. A design methodology towards environmental sustainability has been structured, by focusing on the use of data for design purposes and on creating value for the user through meaningful products. It considers the user, the product and the environment as central topics, by giving them the same relevance and the literature review is structured accordingly, investigating needs and requirements, ethical issues, but also current products and future scenarios. During my experience at TU Delft, I spent six months in the Department of Internet of Things at the Faculty of Industrial Design Engineering. Together with computer scientists, we developed a prototype to collect some missing data, establishing the importance of grounding the decision-making on reliable information. IoT and data gathering open a variety of possibilities in monitoring, accessing more precise knowledge of products and households useful for design purposes, up to understand how to fill the gap perceived by the user between needs and solutions. It considered the potential benefits of using IoT indicators to collect missing information about both the product, its use and its operating environment to address critical aspects in the design stage, thus extending products’ lifetime. This thesis highlighted the importance of building multidisciplinary design teams to investigate different classes of requirements, and the need for flexible tools to cope with complex and evolving requirements, the co-evolution of problem and solutions and investigating open-ended questions. This approach leaves room for addressing every step of the traditional life-cycle in a more circular way, shifting the focus from the life-cycle centrality of the previous century to a more complex vision about the product

Artful Systems: Investigating everyday practices of family life to inform the design of information technology for the home

This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.The research in this thesis was motivated by an interest in understanding the work and effort that goes into organising family homes, with the aim of informing the design of novel information technology for the home. It was undertaken to address a notable absence of in-depth research into domestic information and communication technology in the fields of Human Computer Interaction (HCI) and Computer Supported Cooperative Work (CSCW). To that end, this thesis presents an ethnographic study of everyday routines in thirteen family homes. Following an established tradition within HCI and CSCW, the study applies qualitative fieldwork methods as a means to investigate and interpret the empirical materials. Periods of extended observation and semi-structured interviews with the thirteen families over a three-year period form the basis of the empirical material. The materials are analysed using a hybrid perspective composed of a combination of influences from the study of material culture, to interaction analysis and ethnography. The hybrid analytical perspective draws out insights regarding the families’ mundane practices and the artfully devised solutions they use to organise daily life. Four household activities and artefacts are given specific focus: (i) household list making, (ii) the display qualities of refrigerator doors, (iii) the organisation of household clutter, and (iv) the devising of bespoke solutions in organising home life. Broader findings include the observations that people tailor solutions to meet their needs, that optimum efficiency is not the pre-eminent determinant in what method or artefact people choose to organise themselves and their homes, and that homes determine their individual characters in part by how everyday tasks and organisation are accomplished. In short, the personal qualities of these mundane practices are part of what makes a home a home. These findings are used to elicit implications for information technology design, with the aim of encouraging designers of domestic technology to be aware of and respectful towards the idiosyncratic nature of the home, and, wherever possible, to design in such a way as to allow the technology to be appropriated for families’ bespoke tailoring. To evaluate and address this point, two design projects, one on augmented magnets and another on a “media bowl”, are used to develop and test out this approach. Both projects are critically examined to reflect on the efficacy of the design approach and what lessons might be learnt for future studies and design exercises. The combination of detailed ethnographic fieldwork on family homes combined with the development of experimental design projects is intended to deepen the understanding of the mundane behaviours and everyday routines of family homes, in order to better inform the design of information technology for the home

Supporting User Understanding and Engagement in Designing Intelligent Systems for the Home.

With advances in computing, networking and sensing technology, our everyday objects have become more automated, connected, and intelligent. This dissertation aims to inform the design and implementation of future intelligent systems and devices. To do so, this dissertation presents three studies that investigated user interaction with and experience of intelligent systems. In particular, we look at intelligent technologies that employ sensing technology and machine learning algorithm to perceive and respond to user behavior, and that support energy savings in the home. We first investigated how people understand and use an intelligent thermostat in their everyday homes to identify problems and challenges that users encounter. Subsequently, we examined the opportunities and challenges for intelligent systems that aimed to save energy, by comparing how people’s interaction changed between conventional and smart thermostats as well as how interaction with smart thermostats changed over time. These two qualitative studies led us to the third study. In the final study, we evaluated a smart thermostat that offered a new approach to the management of thermostat schedule in a field deployment, exploring effective ways to define roles for intelligent systems and their users in achieving their mutual goals of energy savings. Based on findings from these studies, this dissertation argues that supporting user understanding and user control of intelligent systems for the home is critical allowing users to intervene effectively when the system does not work as desired. In addition, sustaining user engagement with the system over time is essential for the system to obtain necessary user input and feedback that help improve the system performance and achieve user goals. Informed by findings and insights from the studies, we identify design challenges and strategies in designing end-user interaction with intelligent technologies for the home: making system behaviors intuitive and intelligible; maintaining long-term, easy user engagement over time; and balancing interplay between user control and system autonomy to better achieve their mutual goals.PhDInformationUniversity of Michigan, Horace H.

On to the real world : gender and self-efficacy in Excel

Although there have been a number of studies of end-user software development tasks, few of them have considered gender issues for real end-user developers in real-world environments for end-user programming. In order to be trusted, the results of such laboratory studies must always be re-evaluated with fewer controls, more closely reflecting real-world conditions. Therefore, the research question in this paper is whether the results of a Gender HCI controlled study generalize -- to real-world end-user developers, in a real-world spreadsheet environment, using a realworld spreadsheet. Our findings are that the concepts revealed by the original laboratory study appear to be quite robust, being demonstrated in multiple ways in this real-world environment
