Probing user values in the home environment within a technology driven Smart Home project

Smart Home technology looks set to become an increasingly common feature of domestic life. However commercial desire for technical innovation rather than explicit user needs are often the driving force behind the development of Smart Home products and services. This study adapts the Cultural Probe approach developed by Gaver et al. [2] to collect primarily visual data about what people value within their home environment. Whereas Cultural Probes are predominantly used to build empathy with users when designing product concepts, this approach attempted to provide similarly fun and engaging prompts for data collection when the design process and project context required more structured consideration of user needs. This paper presents the method developed, project findings and recommendations on how the method should be applied.

Applying the lens of sensory ethnography to sustainable HCI

Sociological appropriations of practice theory as applied to sustainable design have successfully problematized overly simplistic and individualistic models of consumer choice and behavior change. By taking everyday practices as the principal units of analysis, they move towards acknowledging the socially and materially structured nature of human activity. However, to inform sustainable HCI we also need to understand how practices are part of wider experiential environments and flows of practical activity. In this article, we develop an approach rooted in phenomenological anthropology and sensory ethnography. This approach builds on theories of place, perception and movement and enables us to situate practices, and understand practical activity, as emplaced within complex and shifting ecologies of things. Drawing on an interdisciplinary study of domestic energy consumption and digital media use, we discuss ethnographic and design practice examples. We demonstrate how this theoretical and methodological framework can be aligned with the 3rd paradigm of HCI.

Opportunities and challenges for location aware computing in the construction industry

This paper describes the opportunities for location aware computing to enhance information capture and use within the construction industry. The construction industry is characterized as being slow to take up innovative mobile ICT, despite the highly mobile workforce who must collaborate with a range of on and off-site personnel, and make use of large volumes of information. Based on fieldwork and workshop activities within COMIT (a large-scale mobile IT project within the construction industry), the information used within two key business processes - health and safety audits, and site design problem resolution - is outlined, and the opportunities for support by location aware computing discussed. Some potential challenges are also identified, as is the need to understand how to provide real value (as opposed to just information) to the end user.

Merging a practice-orientated approach with an engineering-driven product development: a case study on home improvement

CALEBRE, a four year research project, is developing technologies to improve the energy efficiency of solid-walled housing in the UK, particularly in the owner occupied market. The engineering partners within the project require very specific information from user-centred design (UCD) practitioners in order to develop innovative technologies. However the project recognises that it is the ‘soft factors’ that must be addressed in order to make these measures acceptable and appealing to householders. This requires a deeper understanding of users’ motivations for improving their homes and the complex interplay of factors relating to aesthetics, lifestyle, life events, energy efficiency and finance. This paper presents how a practice-orientated UCD approach was taken to inform an engineering-driven product development process. It describes two data collection methods used within CALEBRE specifically to address these challenges and focuses on the specific home improvement practice of replacing windows.

The role of VGI and PGI in supporting outdoor activities

This paper explored the question of how volunteered and professional geographic information (VGI and PGI) can be used together in an outdoor recreation context. In particular, consideration is given to what makes each information source valuable to the user, and how this can be used to help developers of GIS provide more useful, usable and satisfying products. The assumption that VGI is inferior to PGI is shown to be unfounded; rather each has its own strengths in describing particular aspects of the user information landscape. Considering the opportunities to influence user activities, both VGI and PGI have a greater ability to influence the user in the planning phase than actually during the activity. The importance of the author of the information (volunteer or professional) is shown to be of less importance to the end-user than the characteristics which describe the information in terms of communication, frequency of updates and accessibility.

Bottom-up grassroots innovation in transport: motivations, barriers and enablers

Abstract There is a growing phenomenon of grassroots innovation, that is, that triggered by individual users or communities (physical or virtual) seeking a solution to a personal or societal problem. This has great potential as a new source of sustainable transport innovations, but has received little attention to date. This study conducted 16 in-depth interviews and a workshop with grassroots innovators in transport. A detailed thematic analysis of the interview data identified: catalysts for the idea and the motivation behind its pursuit; the barriers experienced (those that were overcome and those that were not); and the enablers that permitted the innovations to continue and to flourish. The paper concludes by identifying the conditions that need to exist for such innovations to be created, developed and exploited in order that their potential for increasing the sustainability of the transport system can be fulfilled.

Empirical investigation of the impact of using co-design methods when generating proposals for sustainable travel solutions

Abstract This paper presents an empirical comparison of idea generation within the context of reducing the number of single occupancy car journeys to and from a UK university campus. Separate co-design and consultative groups were matched with respect to (1) creativity when problem solving, (2) normal commuting mode and (3) intention to adopt sustainable behaviours. The co-design group generated a significantly greater number of innovative ideas than the consultative group (using an email-based methodology); however, this was due to the greater number of total ideas (rather than the higher proportion of innovative ideas) generated by this group. The co-design group was able to think more systemically about potential solutions and generate proposals that were not either linked to their own commute mode, or aligned with any one specific mode of transport. The findings suggest that co-design offers benefits as a process for idea generation within the sustainable travel context as it promotes idea generation and a more holistic perspective on the problem and potential solutions.

Situating Digital Interventions: Mixed Methods for HCI Research in the Home

One of the enduring problems of researching and designing digital technologies for the home is that both media technologies and uses tend to be dispersed spatially and temporally throughout the environment and routines of home.This raises a number of methodologically challenging issues: how digital media technologies are situated amongst other technologies; how materialities and textures shape the experience of home; the ways in which practices of media use are entangled with the other activities and practices that are part of the routines of home; and how digital media content and communications create part of a wider ecology of communication and interaction in home environments. In this article, we outline a methodological and practical response to these questions and describe its application through the development of tailored interdisciplinary research methods. RESEARCH HIGHLIGHTS • This paper describes research undertaken within an interdisciplinary energy project that is seeking to explore domestic energy consumption and everyday digital media use through the individual and combined lenses of engineering, design, social and computer sciences. • The paper describes the interdisciplinary application of two methods that were enacted within participants’ homes: the interactive floor plan method; and video ethnography tour and re-enactment methods. • The benefits of embedding design research in this way are discussed in relation to studying the use of technology in the home and recent research trends in ubiquitous computing.

Multidisciplinary research: should effort be the measure of success?

ABSTRACT Energy demand reduction and flexible demand from dwellings will play a critical role in achieving a low-carbon future. There remain many unanswered questions around the interaction of people with their environment and the technical systems that service them and, as a result, multidisciplinary research is a principal component of research funding internationally. However, relatively little published work considers the operational issues in undertaking epistemologically diverse, academic research projects. This paper makes a contribution by quantifying the operational effort involved in data collection on a large multidisciplinary project and connecting the operational issues encountered to knowledge production. It is found that the cost of the data gathering is £46,000/home, and participants can give upwards of 217 hours of their time per house engaging with data-gathering activities. The rate of knowledge production is found to be approximately three publication/full-time equivalents (FTE) over the lifetime of the project and the risk to generating interdisciplinary insights is shown to be dependent on largely unforeseeable operational issues that compound the characteristic differences in the collection of the data utilized by social and technical research communities.

Using mobility as a conceptual framework for informing the design of mobile ICT for construction professionals

This paper illustrates how the concept of mobility can be used to consider how contextual factors shape user requirements for mobile ICT. The spatial, temporal and contextual mobility of construction professionals is described based on fieldwork conducted within the UK. A distinction between the mobility of workers when they are operating remotely within a geographically distributed team and when they are working cooperatively with others co-located on site is reported. The implications of this finding are discussed in relation to the mobile ICT needs of construction professionals.
